Abstract

Techniques are described for accounting for travel time in scheduling appointments in an electronic calendar. For example, a travel time between appointments may be identified and a time block may be reserved on a calendar application to account for such travel time. Geographic locations of adjacent appointments in a calendar may be determined and a route between the geographic locations also may be determined. A travel time associated with traveling the route between the geographic locations may be computed and the computed travel time may be compared to unscheduled time between the adjacent appointments in the calendar to determine whether the unscheduled time exceeds the travel time. If it is determined that the unscheduled time exceeds the travel time, a time block may be reserved on the calendar application to account for the travel time.

This disclosure relates to meeting notification and modification service.

BACKGROUND

A user may populate an electronic calendar with appointmeri :s that take place at different locations. The electronic calendar may be, for example, a Microsoft Outlook calendar, and may be manually programmed to include a date and time of appointments and locations associated with the appointments.

SUMMARY

In one aspect, travel time between appointments is identified and a time block on a calendar application is reserved to account for such travel time. A first appointment in a calendar application is identified, and a geographic location of the fi 1rst appointment is identified. A second appointment that occurs later in time than the fc rst appointment in the calendar application is identified, and a geographic location of th e second appointment to the geographic location of the second appointment s identified, and a travel time associated with the route is identified. An amount of u scheduled time between the first appointment and the second appointment is deter lined, and it is determined whether the amount of unscheduled time exceeds the travel time. If it is determined that the amount of unscheduled time exceeds the travel time, a time block is reserved on the calendar application to account for the travel time.

Implementations may include one or more of the following features. For example, an ending time of the first appointment may be identified, a starting time of the second appointment may be identified, and the ending time of the first app intment may be subtracted from the starting time of the second appointment. In some implementations, it may be determined whether the amount of unscheduled time exce Is the travel time by more than a threshold amount. If it is determined that unscheduled time exceeds the travel time by more than the threshold amount, a message may be rovided that informs a user of the unscheduled time.

A reminder for the second appointment may be automatically set without user input. The reminder may be set for a specified time that precedes tie starting time of the second appointment time by at least the travel time to the second appointment. A notification window may be displayed at the specified time that precedes the starting time of the second appointment time by at least the travel time to the second appointment. The notification window may be structured and arranged to remind the user about the second appointment. hi some examples, it may be determined whether the travel time exceeds the amount of unscheduled time, and, if it is determined that travel tim exceeds the amount of unscheduled time, an alert message may be provided to inform the user that, based on the current scheduling of the first and second appointments, the us would not have enough time to arrive at the second appointment location. In these examples, one or more suggestions may be provided to enable the user to respond to the a ;rt message. The one or more suggestions may include a suggestion for at least one of: ( ) leave the first appointment sooner than the scheduled ending time of the first app )intment, (2) cancel, one or both of the first or second appointments, (3) reschedule the l:irst or second appointment, and (4) notify the other attendees of the second appoi Ltment, or another designee, that the user will arrive late. Further, in these examples, people attending the second appointment may be identified, and time availability of the people attending the second appointment may be identified. Based on the time availability of the people attending the second appointment, steps may be taken to reschedul ; the second appointment at a mutually convenient time for people attending th second appointment, In some implementations, the calendar application may be ccessed via a navigation application in response to activation of a transferring cc titrol tool that appears within an interface of the navigation application, and the first appo ntment and the second appointment may be identified in the calendar application. In thes implementations, the transferring control tool may be configured to import time and geographic information of the first and second appointments to the navigation application. Tl e transferring control may be further configured to cause the navigation application to i< ;ntify the route and the travel time associated with the route, calculate the remaining time between the ending time of the first appointment and the starting time of the second appointment, determine whether the remaining time exceeds the travel time, and instruct th i; calendar application to place the hold between the first appointment and the second appointment to account for the travel time if it is determined the remaining time exceeds the tπivel time. In some examples, the calendar application may be accessed via a client device, and the first appointment and the second appointment may be identified in the calendar application. In these examples, the client device may interface between the calendar application and a navigation application. The calendar application may be accessed in response to activation of a transferring control tool within the clien : device, and the ending time and the geographic location of the first appointment and the starting time and the geographic location of the second appointment maybe cornmuiicated to the navigation application in response to the activation of the transferri tig control.

The current location of a user may be monitored, and a change in the current location of the user may be identified. The route extending from the geographic location of the first appointment to the geographic location of the second ap pointment may be referenced and it may be determined whether the current location c f the user exceeds a threshold amount from the route. If it is determined that the current location of the user exceeds the threshold amount from the route, the user may be provided with direction to the second appointment from the current location of the user. hi another aspect, a first appointment in a calendar applicat: on is identified, a geographic location of the first appointment is identified, and a tim 2 of the first appointment is identified. A request to schedule a second appointment at a requested time is received from a user, and a geographic location of the secoi d appointment is identified. A route extending between the geographic location of ti: e first appointment

the updated travel time is not more than the threshold greater than |)he time required by the travel time entry, the travel time entry is maintained.

Implementations may include one or more of the following features. For example, conditioned on determining that the updated travel time is more th;ιn the threshold greater than the time required by the travel time entry, one or more alternative routes of travel to the geographic location of the appointment scheduled in the calendar application associated with the user may be identified, and one or more a ; lternai ive travel times associated with each of the identified one or more alternative routed of travel may be determined. It may be determined whether at least one of the one G r more alternative travel times is less than the updated travel time. Conditioned on ;ermining that at least one of the one or more alternative travel times is less than the upda ed travel time, at least one of the one or more alternative routes of travel for which the on i or more alternative travel times is lowest may be selected, and the user may be alerted ibout the selected at least one of the one or more alternative routes of travel. Condition :d on determining that at least one of the one or more alternative travel times is not less th m the updated travel time, the user may be alerted about current travel conditions and th user may be informed that the route of travel remains most efficient. hi some implementations, the travel time entry may corresp and to an estimated travel time needed for the user to, using the route of travel, travel fj om a first geographic location of a first appointment to a second geographic location of a second appointment, hi these implementations, conditioned on determining that the upd ted travel time is more than the threshold greater than the time required by the travel time intry, a time between an ending time of the first appointment and a starting time of the se cond appointment may be determined, and the updated travel time may be compared with he time between the ending time of the first appointment and the starting time of the sec ond appointment.

Based on comparison results, it may be determined whether the updated travel time is greater than the time between the ending time of the first appointm s;nt and the starting time of the second appointment. Conditioned on determining that ie updated travel time is greater than the time between the ending time of the first appoint nent and the starting time of the second appointment, the user may be alerted that at leas one of the first appointment and the second appointment needs to be modified to account for the updated travel time. Conditioned on determining that the updated travel til e is not greater than the time between the ending time of the first appointment and the starting time of the second appointment, the travel time entry may be updated to correspond to the updated travel time; and the user may be alerted of the updated travel time mtry. The user may be alerted that the user needs to leave the fϊrc t geographic location of the first appointment earlier than previously scheduled. Conditi ined on determining that the updated travel time is greater than the time between the endiinng time of the first appointment and the starting time of the second appointment, attendees of the second appointment, or another designee, may be alerted that the user ma] arrive late to the second appointment.

Conditioned on determining that the updated travel time is nore than the threshold greater than the time required by the travel time entry, one or more alternative routes of travel from the first geographic location of the first appointment to the second geographic location of the second appointment may be identified, and one or r iore alternative travel times associated with each of the identified one or more alternative routes of travel may be determined. It may be determined whether at least one of the o: e or more alternative travel times is less than the updated travel time. Conditioned on ά termining that at least one of the one or more alternative travel times is less than the upd∑ ted travel time, one of the one or more alternative routes of travel for which the one or m i<o rree alternative travel times is lowest may be selected, and the time between the ending e of the first appointment and the starting time of the second appointment may e compared with the alternative travel time associated with the selected alternative rout< of travel. Based on comparison results, it may be determined whether the time betwee: i the ending time of the first appointment and the starting time of the second appointment ; greater than the alternative travel time associated with the selected alternative route of travel. Conditioned on determining that the time between the ending time of the first appointment and the starting time of the second appointment is gre iter than the alternative travel time associated with the selected alternative route of travel, the travel time entry may be updated to correspond to the alternative travel ti ne associated with the selected alternative route of travel, and alerting the user may be alerted of the updated travel time entry and the selected alternative route of travel.

Alerting the user that at least one of the first appointment amd the second appointment needs to be modified to account for the updated trave time also may be conditioned on determining that the time between the ending time f the first appointment and the starting time of the second appointment is not greater than he alternative travel time associated with the selected alternative route of travel, and updating the travel time entry to correspond to the updated travel time and alerting the user of the updated travel time entry also may be conditioned on determining that at least on< : of the one or more alternative travel times is not less than the updated travel time.

In a further aspect, a travel time entry in a calendar associa ed with a user is automatically modified in response to cancellation of a corresponding appointment entry in the calendar associated with the user. Cancellation of an appoiπ ment entry in a calendar associated with a user is detecting, and, in response to det :cting cancellation of the appointment entry in the calendar associated with the user, it is determined whether the appointment entry is related to a travel time entry in the calend ir associated with the user. Conditioned on determining that the appointment entry is re .ted to a travel time entry in the calendar associated with the user, the travel time entry related to the appointment entry is identified, and the travel time entry is modified to account for cancellation of the appointment entry.

Implementations may include one or more of the following features. For instance, the user may be informed of the modification of the travel time ent y as a consequence of the cancellation of the appointment entry. It may be determined th it the travel time entry is near a beginning or an end of a calendar day, and one or more default travel locations corresponding to typical travel by the user at the beginning or the end of the calendar day may be identified. The travel time entry and the identified one or i iore default travel locations may be identified, and the travel time entry may be modi (led to account for cancellation of the appointment entry based on the analysis. hi some implementations, one or more calendar entries sch duled prior or subsequent to the travel time entry may be identified, and the trav time entry and the identified one or more calendar entries scheduled prior or subsequent to the travel time entry may be analyzed. The travel time entry may be modified to ccount for cancellation of the appointment entry based on the analysis. In these implemen ations, the appointment entry may be a first appointment entry, and a second ppointment entry scheduled immediately prior to the travel time entry may be identii ed. It may be determined that, after cancellation of the first appointment entry, m calendar entries are scheduled more than a threshold amount of time subsequent to the ravel time entry. The travel time entry may be cancelled, and the user may be informed c f the cancellation of the travel time entry.

In some examples, the appointment entry may be a first appointment entry, and a second appointment entry scheduled immediately subsequent to th travel time entry may

and a starting time of the third appointment may be determined, and the first travel time may be compared with the time between the ending time of the sedond appointment and the starting time of the third appointment. Based on comparison re suits, it may be determined whether the first travel time is greater than the time be ween the ending time of the second appointment and the starting time of the third appointment. Conditioned on determining that the first travel time is not greater than the time bei een the ending time of the second appointment and the starting time of the third appoiη tment, the request to schedule the first appointment may be granted, and a travel time ei try corresponding to the first travel time associated with traveling from the first geographic location to the third geographic location may be added in the calendar associated vith the user.

Conditioned on determining that the first travel time is greater thai the time between the ending time of the second appointment and the starting time of the third appointment, the user may be alerted that insufficient travel time exists for scheduli: g the first appointment at the first time.

In some examples, the user may be able to set a default parameter that indicates whether or not the user wishes to allow travel time to be scheduled during telephone or video conference call appointments. The user may be asked whetr er the user wishes to allow travel time to be scheduled during the second appointment, i nd an answer may be received from the user indicating whether the user wishes to allow travel time to be scheduled during the second appointment.

In another aspect, unscheduled time between two appointm :nt entries in a calendar other than travel time is identified and options are present 3d to a user for using the unscheduled time. At least one of a first appointment entry in calendar associated with a user and a second appointment entry in the calendar associa ed with the user is identified. The first appointment entry is associated with a first ge graphic location, the second appointment entry is associated with a second geographic 1 >cation that is different than the first geographic location, and a starting time of the secon appointment entry is subsequent to an ending time of the first appointment entry. A tra el time entry corresponding to a travel time between the first geographic location associated with the first appointment entry and the second geographic location associated with the second appointment entry is identified, and it is determined whether a time between the ending time of the first appointment entry and the starting time of the secc Ld appointment entry is more than a threshold greater than time required by the travel tin e entry. Conditioned on determining that the time between the ending time of the first appointment entry and the starting time of the second appointment entry is more than a th eshold greater than the time required by the travel time entry, unscheduled time, other tha i travel time, between the first appointment entry and the second appointment entry is idt ntified, one or more options for using the identified unscheduled time are identified, an 1 the identified one or more options are presented to the user.

Implementations may include one or more of the following features. For example, the first appointment entry in the calendar associated with the user and the second appointment entry in the calendar associated with the user may be dentified. The ending time of the first appointment entry maybe determined, the starting time of the second appointment entry may be determined, and the time between the ei ding time of the first appointment entry and the starting time of the second appointment entry may be computed. The time between the ending time of the first appointm ent entry and the starting time of the second appointment entry with the time require i by the travel time entry may be compared. Based on comparison results, it may be d ϊtermined whether the time between the ending time of the first appointment entry and the starting time of the second appointment entry is more than the threshold greater than t e time required by the travel time entry. hi some examples, information related to one or more optiφs available for using unscheduled time may be accessed, and a time associated with eac ofthe one or more options may be determined based on the accessed information rela ed to the one or more options available for using unscheduled time. The determined tim associated with each of the one or more options may be compared with the identified un scheduled time, and, based on comparison results, options for which the determined tim : is less than or equal to the identified unscheduled time may be identified. In these exar lples, information related to interests of the user may be accessed and one or more op ions may be selected from among the identified options for which the determined time is less than or equal to the identified unscheduled time based on the information related to the interests of the user.

Also, an option to spend more time at the first geographic 1 cation subsequent to the first appointment may be identified, an option to spend more tii ie at the second geographic location prior to the second appointment may be identified , and/or an option to visit a point of interest located proximate to the first geographic ocation may be identified. In addition, an option to visit a point of interest located )roximate to the second geographic location may be identified, an option to visit a p )int of interest located along a route between the first geographic location and the second geographic location may be identified, and an option to reschedule at least one of the first and second appointments to minimize the identified unscheduled time may be dentified.

In a further aspect, time associated with modality-specific i icidentals to travel is included in determining a travel time for scheduling calendar appo ntments. A first appointment associated with a calendar of a user is identified, and ; . second appointment associated with the calendar of the user is identified. The first app< intment corresponds to a first geographic location, and the second appointment corresponds to a second geographic location that is different than the first geographic locati >n. A route between the first geographic location and the second geographic location is dentified, and a modality of travel for traveling the route between the first geograp ic location and the second geographic location is determined. A modality-based trave time associated with traveling the route between the first geographic location and the se ;ond geographic location using the determined modality of travel is determined, anc at least one incidental travel time associated with traveling the route between the first gee graphic location and the second geographic location using the determined modality of ti ivel is determined. A total travel time for traveling the route between the first geographic location and the second geographic location is determined based on the determined nodality-based travel time and the determined at least one incidental travel time, and scheduling of the first appointment and the second appointment is handled based on the determined total travel time.

Implementations may include one or more of the following features. An automobile may be determined as the modality of travel for travelir g the route between the first geographic location and the second geographic location, ai:.d a mapping device may be used to determine an automobile travel time associated witi traveling the route between the first geographic location and the second geographic Io ation using the automobile. A walking travel time associated with walking from a building to the automobile prior or subsequent to traveling the route between the first geographic location and the second geographic location using the automobile may be determined, and the walking travel time may be added to the automobile travel time

In some implementations, an airplane may be determined as the modality of travel for traveling the route between the first geographic location and the second geographic location, and an air travel time associated with traveling the route h rtween the first geographic location and the second geographic location using the airplane may be determined. A security travel time associated with going through se< cunty prior to boarding the airplane may be determined, and the security travel ti ιm: < e may be added to the air travel time.

In some examples, electronic data associated with the first ppointment may be accessed, electronic data associated with the second appointment may be accessed, and information associated with a distance between the first geography location and the second geographic location may be accessed. The electronic data issociated with the first appointment, the electronic data associated with the second appoin|ment , and the information associated with the distance between the first geograp ic location and the second geographic location may be analyzed. Based on the analysj s, the modality of travel that provides the shortest travel time for traveling the route ;tween the first geographic location and the second geographic location may be automatically determined.

Further, at least one of content associated with the first appointment and a geographic location field associated with the first appointment ma] be accessed, and a driving map associated with traveling between the first geographic location and the second geographic location may be accessed. The driving map may account for potential driving routes between the first geographic location and the second geographic location.

A walking map associated with traveling between the first geographic location and the second geographic location may be accessed. The walking map may account for potential walking routes between the first geographic location and the second geographic location.

The user may be able to select the modality of travel for traveling the route between the first geographic location and the second geographic location, m addition, multiple, different modalities of travel for traveling the route between the first geographic location and the second geographic location may be determined, arid a modality-based travel time associated with traveling the route between the first gee graphic location and the second geographic location using the determined multiple, different modalities of travel may be determined. At least one incidental travel time associated with transitioning from a first modality of travel to a second modality oJ travel may be determined.

In one aspect, an appointment in a calendar application is ic entified, and a geographic location of the appointment is identified. An appointm ;nt time at which the appointment is due to start and a current time are identified, and an amount of time remaining between the current time and the appointment time at wl ich the appointment is due to start is identified. At least a first participant of the appointn ;nt is identified, and a geographic location of the first participant of the appointment is id mtified at the current time. A route extending from the geographic location of the first p aticipant to the geographic location of the appointment is identified, a travel time i isociated with the route is identified, and it is determined whether the travel time exc ;eds the amount of time remaining until the appointment time. If it is determined that he travel time exceeds the amount of time remaining, a communication is sent.

Implementations may include one or more of the following features. For example, the travel time may be identified based on a current road condition or traffic flow, or the travel time may be identified based on a historic traffic flow. A mi dality of travel of the first participant to the geographic location of the appointment may >e identified, and, based on the modality of travel, the travel time associated with the oute may be identified.

Also, a time threshold at which travel could be completed b y adding the travel time to the current time may be identified, and a later time to schec lie the appointment may be determined based on the time threshold. The later time ma be the same as or later than the time threshold. The appointment time may be postpo aed to the later time to thereby enable the first participant to arrive at the geographic locat: on of the appointment.

Based on the postponed appointment time, updated appointment in ormation may be sent to at least one participant of the appointment or another designee.

In some implementations, the first participant may be alerte 1 that the first participant will be late to the appointment, and/or a second particip mt, other than the first participant, may be alerted that the first participant will be late to tl appointment. In these implementations, the second participant may be informed of ie geographic location of the first participant and the travel time of the first participant to ie geographic location of the appointment, and the second participant may be informed th< t the appointment is being changed to account for the travel time.

In some examples, the calendar application of the first and s ;cond participants may be accessed, and time availability of the first and second parti( ipants may be identified. In these examples, a mutually convenient time for the fi st and second participants to participate in a rescheduled version of the appointm nt may be determined based on the time availability of the first and second participants, a id the appointment may be automatically rescheduled at the mutually convenient time or the first and second participants. Further, in these examples, travel time may be accoui ted for in each of the first and second participants' schedules, and the mutually convenie it time may be selected from among multiple mutually convenient times based on, among other factors, temporal proximity to geographic locations associated with adjacei t appointments in one or both of the first and second participants' calendars. Also, one or more suggestions may be provided to the first articipant to respond to the alert message. The one or more suggestions may include a s ggestion to change the modality of travel used to compute the travel time associated w th the route, and/or a suggestion to send a message to the second participant informing tl ) second participant of an estimated arrival time. Telephone contact information may b accessed for the second participant, and a suggestion may be provided to the first p; ticipant to call the second participant. The suggestion may include a telephone numbs r for the second participant determined based on the accessed telephone contact infi rmation for the second participant.

In some implementations, a current geographic location of the first participant may be identified. In these implementations, the current geographi location of the first participant may be identified based on a location-based technology utilized by a client device of the first participant. The client device may utilize a glob positioning system, Further, a notification window may be displayed at a specified time that precedes the appointment time by at least the travel time to the geographic locat Dn of the appointment if it is determined that the travel time does not exceed the amount o time remaining until the appointment time.

In another aspect, appointment information within a calend; r application is dynamically updated. An appointment within a calendar applicatio i is identified, and appointment times at which the appointment is due to start and due ;o end are identified. It is identified that the appointment has been delayed for a certain a nount of time, and at least one remaining appointment within the calendar application is dentified. A need to reschedule at least one remaining appointment is determined based >n the certain amount of time that the appointment has been delayed, it is confirmed with it least one participant of the appointment that the remaining appointment should be reschi duled. The remaining appointment is dynamically rescheduled within the calendar applies tion such that a starting time of the remaining appointment is postponed by the cert iin amount of time.

Implementations may include one or more of the following features. For instance, participants of the remaining appointment maybe informed of the i scheduling of the remaining appointment. Availability of participants of the appointi ient at the postponed starting time may be confirmed, and the participants of the appoint nent may be notified when conflicts with the postponed starting time exist. hi a further aspect, travel conditions are monitored and chaj ges to travel conditions associated with one or more participants traveling to an φpointment are dynamically processed. An amount of time remaining until an app ήntment time at which an appointment is due to start is identified, and a travel time corres >< onding to a route of travel associated with one or more participants traveling to the app intment is identified.

Based on the identified amount of time remaining until the appoint nent time ; and the identified travel time corresponding to the route, it is determined it at the one or more participants traveling to the appointment are estimated to arrive at 1 ie appointment on time. Travel conditions for the route of travel associated with the e nd or more participants traveling to the appointment are monitored and a change in travel conditions is detected for the route of travel associated with the one or more participants traveling to the appointment. In response to detecting the change in travel conditions, an updated amount of time remaining until the appointment time at which the ppointment is due to start is determined, and a current location of the one or more partic pants is determined.

Based on the current location of the one or more participants, an up dated travel time corresponding to the route of travel associated with the one or mon participants traveling to the appointment is determined. Based on the updated amount of time remaining until the appointment time and the updated travel time corresponding to I he route of travel, it is determined that the one or more participants traveling to the appoir :ment are estimated to arrive at the appointment late based on the changed travel conditions. In response to determining that the one or more participants traveling to the appointment are estimated to arrive at the appointment late based on the changed travel conditions, a communication is sent.

Implementations may include one or more of the following features. For example, one or more alternative routes may be identified for the one or mor: participants traveling to the appointment, one or more alternative travel times associated vith each of the identified one or more alternative routes of travel may be determined, and it may be determined whether at least one of the one or more alternative trave times is less than the updated travel time. Conditioned on determining that at least one o the one or more alternative travel times is less than the updated travel time, at least ne of the one or more alternative routes of travel for which the one or more alternative tra el times is lowest is selected, and the one or more participants are alerted about the selected at least one of the one or more alternative routes of travel. Conditioned on determining that at least one of the one or more alternative travel times is not less than the updated travel time, the one or more participants are alerted about current travel conditions and an informed that the route of travel remains most efficient.

In some examples, an alert message may be sent to at least me of the participants of the appointment. The alert message may indicate that the one or more participants traveling to the appointment are estimated to arrive at the appointrr ent late based on the changed travel conditions. Also, the appointment may be dynamic illy rescheduled based on the updated travel time, and the participants of the appointment nay be notified that the appointment has been dynamically rescheduled. One or more s αbsequent appointments in a calendar of at least one of the participants of the appointment may be identified, and the one or more subsequent appointments may be d] namically rescheduled based on the dynamically rescheduled appointment.

In yet another aspect, a participant is assisted with a calendar appointment when the participant diverges from a suggested route for traveling to the alendar appointment.

A current geographic location of a participant traveling to an appointment scheduled in a calendar application used by the participant is determined, and info mation indicative of the suggested route of travel is accessed. The geographic location f the participant is compared to one or more geographic locations associated with the i oute of travel suggested for the participant, and, based on comparison results, it i determined whether the current geographic location of the participant traveling to the appointment differs more than a threshold from the one or more geographic locations associated with the route of travel suggested for the participant.

Conditioned on determining that the current geographic loc; lion of the participant traveling to the appointment differs more than the threshold from e one or more geographic locations associated with the route of travel suggested ff pr the participant, an updated route of travel to the appointment is determined based on the current geographic location of the participant, and a travel time associated with the upd lated route of travel to the appointment is determined. Based on the travel time associatec with the updated route of travel, it is determined whether the participant traveling ak ng the updated route is estimated to arrive at the appointment on time. Conditioned oonn de :termining that the participant traveling along the updated route is estimated to arrive it the appointment on time, the participant is provided with information related to the updited route of travel. Conditioned on determining that the participant traveling along the updated route is not estimated to arrive at the appointment on time, the participant is provided with information related to the updated route of travel, and a communic kion is sent.

Conditioned on determining that the current geographic loc ;ation of the participant traveling to the appointment does not differ more than the threshol .ii from the one or more geographic locations associated with the route of travel suggested or the participant, it is determined whether the current geographic location of the participant is on the route.

Conditioned on determining that the current geographic location o the participant is not on the route, information is provided to the participant related to h<j w to return to the route.

Implementations may include one or more of the following features. For example, an alert message may be sent to at least one of the participants oft e appointment. The alert message may indicate that the participant traveling to the app< intment is not estimated to arrive at the appointment on time. The appointment nj ay be dynamically rescheduled based on the travel time associated with the updated re ute of travel to the appointment, and the participants of the appointment may be notifis;d that the appointment has been dynamically rescheduled. One or more subs juent appointments in a calendar of at least one of the participants of the appointment ma be identified, and the one or more subsequent appointments may be dynamically resche J< iled based on the dynamically rescheduled appointment. hi another aspect, time associated with modality-specific incidentals to travel is accounted for in dynamically assisting a participant in handling an appointment. An appointment in a calendar associated with a participant of the appointment is identified, and an appointment time at which the appointment is due to start ar d a current time are identified. An amount of time remaining between the appointment time at which the appointment is due to start and the current time is identified, and a geographic location of the appointment is identified. A current geographic location of the participant of the appointment is identified, and a route extending from the current g< ographic location of the participant to the geographic location of the appointment is iden ittified. A modality of travel for traveling the route extending from the geographic location of the participant to the geographic location of the appointment is determined, and a mo dality-based travel time associated with traveling the route extending from the geographic location of the participant to the geographic location of the appointment using the determined modality of travel is determined. Based on the determined modality of trave , at least one incidental travel time associated with traveling the route extending from the geographic location of the participant to the geographic location of the appointment is determined, and a total travel time for traveling the route extending from the geographic location of the participant to the geographic location of the appointment is det< rmined based on the determined modality-based travel time and the determined at least me incidental travel time. It is determined whether the total travel time exceeds the am unt of time remaining until the appointment time. Conditioned on determining that the to al travel time exceeds the amount of time remaining until the appointment time, the partic ipant is dynamically assisted in handling the appointment.

Implementations may include one or more of the following features. For instance, an automobile may be determined as the modality of travel for trav ling the route extending from the geographic location of the participant to the gee graphic location of the appointment, and a mapping device may be used to compute an aui mobile travel time associated with traveling the route extending from the geographic 1 >cation of the participant to the geographic location of the appointment using the lutomobile. A walking travel time associated with walking from a building to the iutomobile prior or subsequent to traveling the route extending from the geographic lo< ation of the participant to the geographic location of the appointment using the iutomobile may be determined, and the walking travel time may be added to the autorr obile travel time,

In some examples, an airplane may be determined as the m( dality of travel for traveling the route extending from the geographic location of the pp;i rticipant to the geographic location of the appointment, and an air travel time asso' iated with traveling the route extending from the geographic location of the participant o the geographic location of the appointment using the airplane may be determined, A security travel time associated with going through security prior to boarding the airplar may be determined, and the security travel time maybe added to the air travel time.

Also, content associated with the appointment may be accei sed, and information associated with a distance extending from the geographic location c f the participant to the geographic location of the appointment may be accessed. The cont ;nt associated with the appointment and the information associated with the distance ex terj ling from the geographic location of the participant to the geographic location of :he appointment may be analyzed, and, based on the analysis, the modality of travel for t aveling the route extending from the geographic location of the participant to the ge< graphic location of the appointment may be automatically determined.

DETAILED DESCRIPTION

It is contemplated that an electronic calendar may be configured to provide appointment-to-appointment directions (e.g., directions from a first appointment to a second appointment and from the second appointment to a third appointment), and/or to account for the travel time between appointments. As such, the use may be alerted when the timing of an appointment presents a potential conflict with anot ier appointment due to the travel time between the two appointments.

Along these lines, a user who maintains a calendar with app ήntments that take place at various locations may find it difficult or cumbersome to ids ntify a travel route through the locations of the user's appointments. Particularly, the u >er may find it time- consuming to manually look-up and print out directions for segmen s ofa travel route before leaving, for example, the user's home or work place.

To reduce the user's burden in identifying a travel route thrc ugh the geographic locations of the user's appointments, in one implementation describ ϊd generally with respect to FIGS. 1A-1B and 2-4, a calendar application is configure 1 to allow the user to automatically generate appointment-to-appointment directions and o reserve a time block between user's appointments to account for the travel time associate d with a route extending from one appointment to the next. To this end, the calenc ar application includes a navigation component and further includes a control opti m, manifested by an icon or a "setting," selection of which results in generation a travel route between multiple appointments and further results in reservation of a time block within the user's calendar to account for the travel time associated with the travel route.

To illustrate, assume that a user has two appointments withi i a calendar application (e.g., a first appointment and a second appointment) an< that the user selects, from within the calendar application, the control icon. In response the calendar application automatically (1) identifies a travel route extending froi i a geographic location of the first appointment to a geographic location of the sec md appointment, (2) identifies a travel time associated with the travel route, and (3) plac :s a hold on the user's calendar to account for such travel time. Additionally, the calenda application may provide the user with a reminder about the user's second appointment, taking into account the travel time associated with the calculated route extending from he geographic location of the first appointment to the geographic location of the s« cond appointment.

As such, depending on the required travel time, the user ma be presented with an option of selecting to travel immediately following the first appoint nent or just prior to the second appointment. Li the absence of sufficient time between he first and second appointments, the user is provided with an alert message at the timi of scheduling the first and/or the second appointment, informing the user of the same, as i lore fully described below with respect to FIGS. 9A-9C. The alert message may be in ε veral forms. Li one example, the alert message is in the form of automatic e-mail to the user (or a person to whom the user delegates the task of keeping the user's calendar), in forming the user of the conflict, hi another example, the alert message is provided as a user interface ("UI") within the calendar application. In either case, the alert message pr ivides the user with several options to allow the user (or a person to whom the user dele ζates the task of keeping the user's calendar) to account for such a conflict.

For instance, the alert message indicates to the user the anticipated need to leave the first appointment earlier than its scheduled ending time or arrivi ig at the second appointment later than its scheduled starting time. Alternatively, th alert message may provide the user with an option to reschedule the first and/or the second appointment. To this end and as described with respect to FIG. 9C, the calendar appl: iation may attempt to identify the availability of the participants of the first appointment i nd/or the second appointment for rescheduling either of the first and/or second appoi ltments. hi this manner, the user is presented with several options to resolve the coi flict (e.g., absence of sufficient travel time) between the first and second appointments. In another implementation described generally with respect o FIG. 5, after taking into the account the travel time associated with the travel route betw een the first and second appointments, the calendar application identifies that there i: an unscheduled time period in the user's calendar, and the calendar application informs the user of the same.

Along these lines, the calendar application may provide the user wi h suggestions as to how the user should fill in the identified gap between the user's firs and second appointments. This may help the user to more efficiently manage tt. ! unscheduled times within the user's daily calendar. hi one example, the calendar application presents to the useij a UI, allowing the user to identify a point of interest at which the user is interested in spending the unscheduled time, hi response, the user identifies a point of interesi (e.g., a coffee shop or a book store) and a geographic location associated therewith. Th geographic location may include a specific address associated with the point of interest, Alternatively, the geographic location may include a geographic area/proximity within which the point of interest should be located, hi either case, this implementation allow s the user to perform a geographically limited search for a particular point of interest to fi l in the identified gap between the user's appointments.

In another implementation described generally with respect a FIGS. 11 and 12A-

12D, instead of generating appointment-to-appointment directions and reserving a time block to account for the travel time between appointments after the ppointments are scheduled, the calendar application generates appointment-to-appoii tment directions and reserves a time block to account for the travel time between the app intments at the time of scheduling an appointment. To illustrate, assume that the user ha ■; scheduled a first appointment within the user's calendar and the user wishes to sched.ile a second appointment within the user's calendar. Upon indicating a desire t<: schedule the second appointment, the calendar notes the proposed time and location of tb e second appointment.

Thereafter, the calendar application automatically identifies . route extending between the first appointment and the second appointment and identifies the travel time associated with the route. If the travel time exceeds the time gap be een the first and second appointments, the calendar application alerts the user of the ame before accepting the second appointment at the requested time. As such, the user immediately realizes the conflict (e.g., absence of sufficient travel time between the first and ;econd appointments) and is allowed to schedule the second appointment at another time t avoid such conflict.

Similarly, the process 200 includes the calendar application dentifying a second appointment in the calendar application (220) and identifying the gi ographic location of the second appointment (225). Identifying the second appointment may include identifying an existing appointment already scheduled within a cale idar application, Alternatively or additionally, identifying the second appointment m iy include receiving a request to schedule a second appointment within a calendar applica ion . The calendar application uses the above-described techniques to identify the geoj raphiic location of the second appointment 120. In doing so, the calendar application real] zes that the geographic location of the second appointment 120 is U.S. Patent a d Trademark Office without a specific address. As such, the calendar application identi: ies a need for identifying an address associated with the U.S. Patent and Tradema k Office. To this end, the calendar application may use an exemplary process 300A ϊ lustrated by FIG. 3 A and an exemplary UI 300B illustrated by FIG. 3B to determine the ddress associated with the U.S. Patent and Trademark Office.

Process 300A begins with determining that the user has not pecified an address corresponding to an appointment location (310). To do so, in one ii lplementation, the calendar application searches the calendar application for the addrei s associated with the appointment. For example and as noted above, the calendar applies tion may reference a location field associated with the second appointment 120 to deterrr ine the address for the second appointment 120. Alternatively or additionally, the calendai application may reference other fields associated with the second appointment 120 a id may search for key words (e.g., a zip code, city, and/or state name) identifying an addrc ss. In the absence of such information, the calendar application concludes that the user h is not specified an address for the appointment location.

Upon identifying that the user has not specified an address f r the appointment location, the calendar application attempts to determine the address associated with the appointment location (320). To do so, the calendar application ma) solicit the user for such information, hi one example, the calendar application present; the UI 300B to the user, which includes an "address" icon, allowing the user to specify an address for the appointment location (e.g., U.S. Patent and Trademark Office). In me example, the selection of the "address" icon launches another UI, allowing the us ;r to specify the address for the appointment. The user may manually enter the addr !ss in the UI or may import the address into the UI from the user's profile. For example, the user's profile may include an entry for "U.S. Patent and Trademark Office" that s] (ecifies the address for "U.S. Patent and Trademark Office." The profile may include t e user s contact/address list. Alternatively, the calendar application may au omatically determine the address for the U.S. Patent and Trademark Office without havin the user to interact with the UI 300B. For example, the calendar application automatically obtains the address for U.S. Patent and Trademark Office from the user's profil

Alternatively, the calendar application may access an online resource (e.g., Internet) to perform a web search or a database search to determine ;he address for the U.S. Patent and Trademark Office. In this manner and in one speci:: c example, after performing the search, the calendar application identifies multiple addresses associated with the appointment.

To ensure the correct address is used, the calendar applicatiob may present another

UI to the user and may request that the user selects from among the multiple addresses associated with the appointment location. Upon identifying the address, the calendar application allows the user to obtain directions to the appointment location (320). To this end, the calendar application includes a directions/mapping selectio L portion 325 in the UI 300B, selection of which provides the user with directions and/o maps to the geographic location of the second appointment 120 from the geographic location of the first appointment 115.

Along these lines, the process 200 includes the calendar application identifying a route extending from the geographic location of the first appomtmei Lt to the geographic location of the second appointment (230). To do so, in one implem mtation, the calendar application has a built in navigation component, allowing it to genei ate directions from the geographic location of the first appointment 115 to the geo graph %c location of the second appointment 120. hi another implementation and as noted a] bove, the calendar application communicates the location information for each appointment to a navigation application that is physically or logically distinct from the calendar Application and requests, from the navigation application, that it identifies the travel route and the travel time associated therewith. The U.S. Patent Application Serial Number 11/618,069, filed on December 29, 2006 and entitled "Communicating Appointment uid/Or Mapping rnformation Among A Calendar Application And A Navigation Ap] lication, describes in detail concepts that effect communications of appointment inforn ation from a calendar application to a navigation application for generating a travel route nd a travel time associated therewith. The entire content of this application is incorporated herein by reference.

(not shown) that displays a travel route extending from the geograplic location of the first appointment to the geographic location of the second appointment, identifies the geographic locations associated with the point of interest along the route, and requests, from the user, to select, from among the identified geographic locations, a location for the point of interest.

Referring again to FIG. 2, if it is determined that the travel time exceeds the amount of unscheduled time (250, no), the calendar application alerts the user of the conflict and provides the user with one or more suggestions to resob re the conflict. In one example, the calendar application presents to the user a UI, providin g one or more suggestions to make able the user to respond to the alert message, The process associated with generating an alert message is more fully described below witit respect to FIG. 9A and the UI providing the user with one or more suggestions is more fully described below with respect to FIG. 9B.

In one implementation, the calendar application is configure I to allow the user to set a travel time reminder, reminding the user to leave the user's current location at a specified time that precedes the starting time of the appointment by it least the travel time to the appointment. In keeping with the previous example describe* with respect to FIGS. IA and IB, the calendar application is configured to allow th : user to set a travel time reminder, reminding the user to leave at a specified time that p ecedes the starting time (e.g., 1 :00 pm) of the second appointment 120 by at least the tr ivel time (e.g., 60 minutes) to the second appointment 120.

FIG. 6 illustrates an exemplary UI 600 that makes able the ui er to set such reminders within a calendar application. The UI 600 includes a rem nder selection portion 610. The reminder selection portion 610 includes one or me re options selection of which instruct the calendar application to remind the user at a "sp icified time" in advance of the allocated travel time block to arrive at a geographic ideation of the second appointment on time, hi one example, the user's selection of the reminder selection portion 610 launches another UI (not shown), allowing the user to S' t the "specified time." For example, the user may request to be reminded about an < ppointment 10 minutes before the time the user should leave the user's present loc; ion to arrive at the appointment location on time. The reminder selection portion 610 so allows the user to specify the manner in which the reminder should be sent to the user. As shown in FIG. 6, the user may choose to receive the reminder via, for example, via ar audio call placed to a telephone, an email, an instant message, and/or "other" options, suα as short message service ("SMS").

The calendar application may be configured to allow the usei to set alert messages, alerting the user about different events, hi one specific e: ample, the user may wish to set an alert message, alerting the user if the travel time assoc ated with the calculated route between the first appointment and the second appointment changes due to a change in the current road conditions, hi another example, the u ser may wish to set an alert message, alerting the user about conflicting appointments. I i keeping with the previous example, the timing of the first and second appointments th it previously did not conflict with each other even after taking into account travel time frc tn the first appointment to the second appointment, may now present a conflict iue to the new calculated travel time and the alert message informs the user of the s, ϊime e. hi yet another example, the user may set an alert message, alerting the user of an unscheduled within the user's calendar application, hi yet another example, the user may se an alert message, providing the user with updated directions and an updated travel timέ if the user deviates from the previously calculated route.

FIG. 7 illustrates an exemplary UI 700 used to allow the user to set an alert message, alerting the user of certain pre-defined conditions/events. The UI 700 includes an alert selection portion 710. As shown, the alert selection portion 10 includes four user-selectable alert options. The first alert option, described below in more detail with respect to FIGS. 8A and 8B, alerts the user if current road conditions change and may suggest an alternate route to the user that avoids problematic routes associated with the change in the road conditions. The second alert option, described below in more detail with respect to FIGS. 9A-9C, alerts the user about conflicting appointments (e.g., absence of sufficient travel time between the appointments) and may suggest possible options to help the user avoid the conflicting appointments.

The third alert option, described above in more detail with respect to FIG. 5, alerts the user about a time period that is unscheduled between the user's appointments and may suggest an alternate schedule to help the user to more efficiently use pe unscheduled time slot. The fourth alert option, described below with respect to FIGS. IOA and 1OB, alerts the user if the user deviates from the previously calculated route and provides the user with new directions based on the user's present location. More particularly, the user's selection of the fourth alert option instructs the calendar application to update the calculated route based on real time information, such that a user deviating from the original route may receive an updated route (an updated effect on a calendar of appointments) to the user's next appointment location.

FIG. 8A illustrates an exemplary process 800A that a calendar application uses to alert a user about a change in current road conditions. In keeping with the previous example and for convenience, the calendar application described witti respect to FIGS.

IA and IB is referenced as performing the process 800A. In particu ar, the process 800A involves the first appointment 115, the second appointment 120, the ;ontrol icon 125, and the travel time block 130. Although the process 800A is described b :low as being performed by the calendar application, it should be understood that i can be performed by a navigation application. Alternatively or additionally, some of t ie actions within the process 800A may be performed by the calendar application and oth :rs may be performed by the navigation application. Alternatively or additionally, the process 800A may be performed by an application that acts as an interface between the na igation and calendar applications.

Moving forward with the calendar application performing the actions of the process 800A, the calendar application may use the process 800A, fc r example, in response to the user's selection of the first alert option in the alert sej ection portion 710 illustrated by FIG. 7. Alternatively or additionally, the calendar app ication may use the process 800A in response to the user's selection of the control icon 125.. hi either case, the process 800A includes the calendar application monitoring the n ad conditions between the user's appointment locations (805). For example, the calendar application monitors the road conditions associated with the previously calculated travel route extending from the geographic location of the first appointment 115 :o the geographic location of the second appointment 120. To do so, in one implementation, the calendar application regularly contacts a server that includes traffic data to obtain current road conditions between the user's appointments. To minimize the burden on the server initially, the calendar application may contact the server less frequently and, as it gets closer to the time the user has to leave the geographic location of the first appointment 115 to arrive on time at the geographic location of the second appointment 120, the calendar application contacts the server more often to obtain more up to date information. Regardless, the calendar application determines that there is a change in the road conditions (810). The change in the road conditions may include events such as traffic, accidents, rush hours, construction, road blocks, and/or adverse weat> ier conditions resulting in a slower recommended speed limit. The calendar application identifies the

alternative routes, from among the identified alternative routes, with! the two lowest travel times). In response to identifying the at least one alternative route with a travel time that is lowest, the calendar application alerts the user of the change in the current road conditions and displays to the user the one or more identified alternaj ive routes, informing the user that the alternative routes will result in an increase in travel iime compared to the initial travel schedule, but also informing the user that they will decrease travel time compared to travel time on the current route under the current road conditions (860).

To alert the user, the calendar application may display to the user a UI informing the user of the time, present location, and the adverse condition, and suggesting that the user takes a different route to the user's next appointment location. iVlternatively or additionally, the calendar application may store the directions associ ited with the new route in the travel time block 130 for later access by the user and ma/ update the travel time associated with the new route.

FIG. 8B illustrates an exemplary UI 800B the calendar application uses to alert a user about a change in current road conditions. The UI 800B inform 3 the user of the present time (e.g., 11 :00 am), the user's present location (e.g., the ft 3t appointment location), and the user's next destination (e.g., the second appointment location). As shown in FIG. 8B, the UI 800B also informs the user that if the user were able to travel under normal conditions, the user could expect to arrive at the Seconal appointment location in 60 minutes. However, problematic conditions adversely Effect the ability of the user to achieve that estimated travel time. In particular, the alert message indicates that "[fjhere is heavy traffic due to an accident on the 1-60" and now it will take the user 3 hours to arrive at the second appointment location.

In one implementation, to estimate the new travel time, the calendar application compares the travel time of the original route under the current road conditions with the travel time of an alternative route and suggests to the user the route vdth the minimum travel time. For example and as shown in FIG. 8B, the calendar application determines the alternative route has the minimum travel time (e.g., 2 hours) and suggests taking the alternative route. The calendar application also communicates to the user to leave immediately if the user wishes to arrive at the second appointment L ation on time. The

UI 800B also makes able the user to view the alternative route via, f Tcr example, selecting the "view" icon. Alternatively or additionally, the user can view the alternative route via, for example, selecting the travel time block 130. It is to be understood that other alternative may be presented to the user. For example, the user may 3e presented with an option to postpone and/or cancel the second appointment and inform the participants of the second appointment of the same.

FIG. 9A illustrates an exemplary process 900A used for generating an alert message informing the user of conflicting appointments. The action- performed by the process 900A are similar to some of the actions performed by the process 200 illustrated by FIG. 2. In keeping with the previous example and for convenienc e, the calendar application described with respect to FIGS. IA and IB is referenced as performing the process 900A. hi particular, the process 900A involves the first appc intment 115, the second appointment 120, the control icon 125, and the travel time block 130. Although the process 900A is described below as being performed by the calendar application, it should be understood that it can be performed by a navigation appli ition. Alternatively or additionally, some of the actions within the process 900A may be performed by . the calendar application and others may be performed by the navigation ipplication.

Alternatively or additionally, the process 900A may be performed by an application that acts as an interface between the navigation and calendar applications

The process 900A may be used, for example, in response to tfte user's selection of the control icon 125. Alternatively or additionally, the process 900A may be used, for example, in response to the user's selection of the second alert option in the alert selection portion 710 illustrated by FIG. 7. In either case, the process 900A iri :ludes the calendar application determining the amount of unscheduled time between the first appointment

115 and the second appointment 120 (910A). The action (910A) is sj milar to action

(240). To this end and as more fully described above with respect to process 400 illustrated by FIG. 4, the calendar application identifies that the amotnt of unscheduled time is about 2 hours. The calendar application then identifies the travel time for the route extending from the geographic location of the first appointment 115 to the geographic location of the second appointment 120 (915A). The actόn (915A) is similar to action (235). For example, the calendar application identifies that the travel time is 2 hours and 30 minutes.

The calendar application then compares the travel time with Ae amount of unscheduled time (920A) and based on the comparison, determines if the travel time exceeds the amount of unscheduled time (925A). The actions (920Aι and (925A) illustrate action (245) in more detail, hi keeping with the above-desc ibed example, the calendar application identifies that the travel time exceeds the amoun of unscheduled time by 30 minutes. Accordingly, the calendar application alerts the iser of the conflict

the host that is used to derive location information. For example, th host may derive location information based on how the client device is accessing the network (e.g., as identified by source IP address or another packet identifier).

In yet another alternative, the present location of the user is a an tomatically determined from the user's profile. For example, the user has associ il . ited profile or contact information indicating a predetermined home and/or office ldcat ion. In one specific example, the user of a client office computer has previously tored the location of the user's office in the user's profile. Thus, the navigation applicatiq: i uses the user's profile to determine the office location.

Upon determining the current location, the calendar application references the originally calculated route (1010) and checks to determine whether tl e current location of the user differs more than a threshold amount from the originally-cal iMilated route (1015).

If not (1015, no), the calendar application checks to determine wheth :r the current location is on the route (1020) and if so (1020, yes), the calendar app ication continues to monitor the current location of the user to account for the possible departure of the user from the route. If, however, the current location of the user is nnoott oonn the route (1020, no), the calendar application shows the user how to return to the originally -calculated route (1025). FIG. 1OC illustrates a UI IOOOC that may be used to help the user to return to the originally-calculated route. After showing the user how to return to tie originally- calculated route, the calendar application waits a period of time (e.g., a predetermined and configurable period of time, a time determined based on the distance from the originally- calculated route, etc.) or until the user has returned to the originally-calculated route, and continues to monitor the current location of the user to account for departure of the user from the originally-calculated route (1028).

If the current location of the user does differ more than a threi ihold amount from the originally-calculated route (1015, yes), the calendar application at erts the user (1030).

In one example, the threshold is 1 mile from the originally calculated route. If the current location of the client device differs more than the threshold amount from the originally calculated route, the calendar application alerts the user (1030) and p! ovides the user with directions to the user's next appointment location from the current location of the client device (1035). Although FIG. 1OA illustrates that actions (1030 and 035) are performed serially, it is possible that actions (1030 and 1035) can be performed simultaneously.

The calendar application may use a UI, such as the one showr in FIG. 1OB, to alert the user and provide the user with updated directions. As desc: bed further below with respect to FIG. 1OB, the alert message also informs the user of the time and location of the user's next appointment and the travel time to the next appoin ment location based on the user's present location.

FIG. 1OB illustrates an exemplary UI IOOOB used to alert a u; ier that the user has deviated from an original route. In particular, the alert message note s to the user that "it is currently 11 :00 am, and it seems you have deviated from the original route. You are presently located at 1100 F St., NW, Washington D.C. 20005."

The alert message also informs the user of the time and locat on of the user's next appointment (e.g., the second appointment 120) and the travel time ( :g., 30 minutes) to the next appointment location based on the present location of the u: :r. The alert message also allows the user to view directions from the present loc tion to the next appointment, hi one implementation, the calendar application deterr iiinnes whether the user arrives on time at the user's next appointment based on the new travel time and informs the user in either case. If the user is going to be late to the a jpointment based on the new travel time, the calendar application may present the user w: th one or more suggestions to avoid such conflict. For example, the calendar applic ition may present the user with options similar to those described with respect to FIG. 9B.

FIG. 1OC illustrates an exemplary UI IOOOC used to alert the user that the user has deviated from the originally-calculated route by less than a threshold amount and helps the user to get back on the originally-calculated route, hi particular, the alert message notes to the user that "it is currently 11:00 am, and it seems you have deviated from the originally calculated route by less than a threshold amount." In keep ing with the example described with respect to FIG. 1OA, the user who is presented with tl e UI lOOOC may have deviated from the route by less than a threshold amount (e.g., 1 mile). Regardless, the alert message IOOOC allows the user to view directions in order t get back on the originally-calculated route.

Other implementations are also contemplated. For example, instead of or in addition to allowing the user to a reserve, within a calendar applicati )n, a time block for the travel time between multiple appointments after the multiple appointments have already been scheduled, as described with respect to FIG. 2, the user is allowed to reserve, within the calendar application, a time block for such travel ime during scheduling of an appointment. As such, in this implementation, the ser immediately realizes the conflict (e.g., absence of sufficient travel time between appointments) at the time of scheduling an appointment, and the user is allowed to sched Ie the appointment at another time to avoid such conflict. This minimizes the hassle of later recognizing such conflict and having to reschedule the already scheduled appointment at that time.

FIG. 11 illustrates an exemplary process 1100 used to make a Die a user to determine presence or absence of a conflict (e.g., absence of sufficient travel time) between an already scheduled first appointment and a second and nejy appointment that the user wishes to schedule at a particular time. In keeping with the previous example and for convenience, the calendar application described with respect :o FIGS. IA and IB is referenced as performing the process 1100. In particular, the process 1100 involves the calendar application interface 110, the first appointment 115, the second appointment 120, the control icon 125, and the travel time block 130.

Although the process 1100 is described below as being perfoiimed by the calendar application, it should be understood that it can be performed by a na-s igation application. Alternatively or additionally, some of the actions within the process 100 may be performed by the calendar application and others may be performed iy the navigation application. Alternatively or additionally, the process 1100 may be p erformed by an application that acts as an interface between the navigation and calendar applications.

The process 1100 includes many of the actions described witi respect to the process 200. As such, for the sake brevity, only the actions that are different is described here in more detail. These actions include actions (1110, 1150, 1155 and 1160). To illustrate, the process 1100 includes the calendar application receivin I, from a user, a request to schedule, within a calendar application, a new (second) ap; ointment 120 at a particular time (1110). To formulate such a request, in one implemertation, the user clicks on the time windows appearing on the calendar application int ;rface 1110. This results in generation of a UI, similar to the one shown and described below with respect to FIG. 12C, soliciting, from the user, to specify the time, date, subje< ;t, and location of the second appointment 120. After identifying this information, the use may save the second appointment 120 within the calendar application by selecting the "save and close" icon.

Before saving the second appointment 120 into the calendar pplication, however, the calendar application may first determine whether the proposed se :ond appointment present a conflict (e.g., absence of sufficient travel time) with an already scheduled first appointment 115. If not (1145, yes), the calendar application schedu !S the second appointment 120 at the proposed particular time (1150). Additional!? ^r, the calendar application also reserves a travel time block within the calendar appϊ: cation to account for the travel time (1155). In one implementation, the calendar applicati n places the travel time block immediately before the starting time of the second appointment, hi another implementation, the calendar application places the travel time block immediately after the ending time of the first appointment. In yet another implementation, the calendar application presents to a user a UI (not shown), allowing the user to :lect where the time block should be located between the first and second appointments. In either case, the user may have the option of removing and/or adjusting the travel tim block placed between the first and second appointments.

However, if it is determined that the amount of travel time exceeds the amount of unscheduled time (1145, no), the calendar application alerts the user i f the conflict and provides the user with suggestions before or at the time of saving the second appointment 120 into the calendar application at the particular time (1160). In one example, the calendar application presents to the user a UI, providing the user witr one or more suggestions in resolving the conflict, as described above in more deta 1 with respect to FIGS. 9A-9C. hi response, the user may simply select to schedule the second appointment at another time that does not present such a conflict.

FIGS. 12A-12D illustrate, within the UIs 1200A-1200D, an ώ emplary sequence of interactions between a calendar application and a user wishing to s Jiedule an appointment using the process 1100 described with respect to FIG 1 FIG. 12A illustrates an exemplary UI 1200A enabling a user to perceive, within the calendar application, an already scheduled appointment and to schedule a new appointment in the absence of a conflict (e.g., absence of sufficient travel time) between :he already scheduled appointment and the new appointment.

The UI 1200A includes a calendar application interface 1210. The calendar application interface 1210 includes, within a particular day (e.g., Mor day, April 23, 2002), an already scheduled first appointment 1215. As shown, the first appointment 1215 is with "patent attorney Karl Renner at 1425 K Street, NW, Washington D.C.

20005." Thereafter, the calendar application receives, from the user, a request to schedule a second and a new appointment 1220, which appears to be with "a patent examiner Joe Smith at U.S. Patent and Trademark Office." As show] , in one implementation, the request is in the form of drag and drop operation. hi particular, the user drags, from another application and into the calendar application interface 1210, the information about the second appointrijient 1220 and drops, within the calendar application interface 1210, the information about he second

The subject field 1235 allows the user to identify the subject ssociated with the third appointment. For example, as shown, the subject associated wi h the third appointment includes "appointment with Dr. Jones." The location fi :ld 1240 allows the user to identifying the geographic location of the third appointment. ΌΓ example, as shown, the geographic location of the new appointment is at "11208 !amp Rd. Bethesda, Maryland, 20854." The starting time and ending time fields 1245, 1 50, identify the starting date/time and ending date/time associated with the third appi intment, respectively. For example, as shown, the starting date/time of the thi ^•d appointment is on Thursday, April 23, 2002 at 11 :00am and the ending date/time of the third appointment is on Thursday April 23, 2003 at 11 :30am. The reminder field 1255 all )ws the user to set a reminder for the appointment. For example, as shown, the user has ecified a reminder 15 minutes in advance of the appointment time.

To schedule the appointment, the user may click on "save anc close" icon 1260.

This causes the appointment information to be saved within the calendar application, and the appointment information to be presented on the calendar applicat on interface 1210 between the first and second appointments 1215 and 1220, as shown n FIG. 12D. However, before or at the time of scheduling the third appointment 1 65, the calendar application again uses the process 1100 to determine whether the tim ng of the third appointment 1265 present a conflict (e.g., absence of sufficient travel time) with the already scheduled first and second appointments 1215, 1220.

To this end, the calendar application automatically identifies first route extending from the geographic location of the first appointment 1215 to the geographic location of the third appointment 1265 and identifies a first travel tim e associated with the first route. Similarly, the calendar application automatically identifie a second route extending from the geographic location of the third appointment 126 to the geographic location of the second appointment 1220 and identifies a second trav 1 time associated with the second route. The calendar application then compares the fi: st travel time with the time gap between the first and third appointments 1215, 1265 anc similarly compares the second travel time with the time gap between the third and seconi appointments 1265, 1220.

If the first travel time exceeds the time gap between the first snd third appointments 1215, 1265 or the second travel time exceeds the time ;ap between the third and the second appointments 1265, 1220, the calendar application akrts the user before or at the time of accepting the third appointment 1265 at the requested t me. As such, the user immediately realizes the conflict and is permitted to schedule U e third appointment 1265 at another time to avoid the conflict. For example, and as shov [αi, the calendar application generates a pop-up window 1270 informing the user of tljie conflict.

Alternatively, if the first travel time does not exceed the time gap between the first and third appointments 1215, 1265 and the second travel time also d :>es not exceed the time gap between the third and second appointments 1265, 1220, the calendar application schedules the third appointment 1265 at the requested time.

Although FIG. 9B illustrates some of the suggestions that may be offered to the user to avoid the conflict between two appointments, other suggestions also are possible. For example, upon determining that two appointments are conflicting (e.g., there is an absence of sufficient travel time from the first appointment location [to the second appointment location), the calendar application may offer to the usei to default to a telephone or video conference to avoid the conflict, hi keeping with the example described about with respect to FIG. 9B, upon realizing that the amount of unscheduled time between the first appointment and the second appointment is Ie s than the travel time between the two, the calendar application may offer to the user to co: duct either the first appointment or the second appointment via telephone.

Along these lines, at a time of scheduling an appointment, thb user may be presented with an option to specify whether an appointment is to be conducted via a teleconference or a video conference. If so, the calendar application does not take into account that appointment for purposes of reserving a time block to account for the travel time. To illustrate, assume that the user has three appointments wi i the user's calendar on a particular day. The first appointment is to be conducted live at 0:00am, the second appointment is to be conducted via a telephone conference at 11 :00; and the third appointment is to be conducted live at 12:00pm. The calendar applic ation realizes that the second appointment is a teleconference or a video conference appointment, and, as such, the calendar application does not reserve a time block for travel time between the first appointment and the second appointment and similarly between the second appointment and the third appointment.

Instead, the calendar application reserves a time block to account for travel time from the first appointment to the third appointment. That is the calendar application intentionally disregards the second appointment for purposes of reserving a time block to account for the travel time, hi one implementation, the user is informed that the travel time between the first and third appointment impinges on the schedu ied second appointment that takes place via a teleconference, for example. And, the user is presented with an option to schedule the travel before, during, or after the intervening teleconference appointment. hi a slightly different implementation, instead of the user explicitly specifying that the appointment is a teleconference one, the calendar application inf :rs such conclusion from the information associated with the appointment. Li one example, if there is a dial- in number and/or a pin number associated with the appointment and thus, is location independent, the calendar application concludes that the appointme is to be conducted via a telephone, and, as such, does not take into account the appointment for purposes of identifying a travel time, hi one implementation, the calendar appliication confirms with the user as to whether the appointment is indeed to be conducted vi a telephone to reduce errors.

Similar to the notion of recognizing and accounting for telephone and/or video conference appointments, the calendar application also may recogni: ;e certain keywords (e.g., airports, flights) or locations (e.g., airports) associated with a calendar event, and may have a particular setting to set aside time in addition to the travd time to account for certain routine activities (e.g., going through security). Similarly, thj calendar application may set aside time to account for other factors, such as, for example, time needed to get from the car to a meeting. In keeping with the example described above with respect to FIG. 9B, the calendar application notifies the user that the travel time : between two appointments is 130 minutes (120 minutes of travel time plus an additional 10 minutes to get from the car to the meeting). As such, the calendar application reserves a time block for 130 to account for the time needed for the user to get from the ca r to the meeting,

In another implementation, the calendar application cancels or modifies the already scheduled travel time block upon determining that the user yishes to cancel an appointment used for the estimation of the travel time block. FIG. 1 E illustrates an exemplary process 1200E used by the calendar application to cancel and/or modify the travel time block upon receiving an indication from the user to cancel an appointment that is used to estimate the travel time block.

The process 1200E includes receiving a notification of an appointment cancellation (1210E). In keeping with the example described with n iSpect to FIG 12D, the calendar application may receive a notification that the first appointment 1215 with the patent attorney Karl Rentier should be canceled. Upon receiving such an indication, the calendar application identifies the travel time block that is based on the canceled appointment (1215E). Toward this end, the calendar application identifies the travel time block 1230 that is reserved for the travel time between the first appointment 1215 and the second appointment 1220. And, the calendar application either cancels or modifies the travel time block (1220E).

In one example, if the only remaining appointment is the second appointment 1220, the calendar application cancels the travel time block 1230. However, and as shown in FIG 12D, if there is a third appointment 1265, the calendar application modifies the travel time block such that it is based on the third appointment 1265 . Although, the third appointment 1265 is shown in FIG. 12D to take place after the first appointment 1215, it is to be understood that the third appointment 1265 can take place before the first appointment 1215. In either case, the calendar application identifies the new travel time block and informs the user of the same (1225E).

Other implementations are contemplated. For example, in an Dther general aspect and as described in more detail below with respect to FIG. 13, the concept :s described herein also relate to a system that dynamically updates appointment i nformation within a calendar application based on the current location of the user scheduled to participant in an appointment. The system identifies the current location of the user ^•., and based on the current location of the user the system approximates the arrival of th : user to the geographic location of the user's next appointment. To do so, the syi tem may take into account the user's modality of travel. The modality of travel may include driving, walking, public transportation, and/or other means of traveling, such as, bicycling. Based on the estimated arrival time, the system may inform the user that the user is running late to the meeting. Similarly, the system may inform other participants of the appointment, thereby saving the remaining participants of waiting for the user.

By way of example, GPS or other location-based information about at least one of the participants in the appointment can be used to automatically (e.g on the fly) update the appointment in the participant's electronic calendar application (e .g., Microsoft Exchange). To this end, if the participant is 20 minutes walk or drive away from and just underway to an appointment that is due to start now, the appointmem can be rescheduled to start in 20 minutes, saving the remaining participants from waiting . In one implementation, to determine the travel time of the participant to the geographic location of the appointment real time traffic and travel data can be leveraged to account for the participant's travel time to a distant meeting. Similarly, this information can be used to alarm the participant as to when he/she needs to depart in order to arrive at the geographic location of the appointment on time.

In another general aspect and as described in more detail with : respect to FIG. 18, the concepts described herein also relate to a system for identifying hat a user's appointment has been delayed and dynamically rescheduling the use r's subsequent appointments to account for the delay. To illustrate, assume that the doctor is running late to his or her first patient meeting and as such the first appointment that is due to start at 9:00am and last until 9:15am actually starts at 9:15am. The system realizes this delay, identifies subsequent appointments within the doctor's calendar, and automatically reschedules the remaining appointments. For example, the system postpones each appointment by 15 minutes. As such the next appointment that was iue to start at 9:15am and end at 9:30am will be postponed such that it will start at 9:30am and end at 9:45am.

The system also may inform other participants of the appointment, thereby saving the remaining participants of waiting for the user. This scenario can be Useful in, for example, allowing patients to delay their arrivals at doctor's offices i :^r doctors are running late.

FIG. 13 illustrates an exemplary process 1300 used for alerting one or more users who are scheduled to participate in an appointment of possible delay of the at least one of the participants to the appointment, hi keeping with the previous example and for convenience, the calendar application described with respect to FIGS . IA and IB is referenced as performing the process 1300. hi particular, the proces 1300 involves the calendar application interface 110, the first appointment 115, and the second appointment

120.

Although the process 1300 is described below as being performed by the calendar application, it should be understood that it can be performed by a naΛ igation application.

Alternatively or additionally, some of the actions within the process 1300 may be performed by the calendar application and others may be performed by the navigation application. Alternatively or additionally, the process 1100 may be performed by an application that acts as an interface between the navigation and calendar applications.

The process 1300 may be activated either manually or auto: .tically. The manual activation may be through a setting (e.g., an icon) appearing in the calendar application or a navigation application. The process 1300 includes the calendar application identifying an appointment within a calendar application (1305) and identifying ii geographic location of the appointment and the time at which the appointment is due to start (1310). To identify the geographic location of the appointment, in one implementation, the calendar application references a location field associated with the appointment.

Alternatively or additionally, the calendar application may reference other fields associated with the appointment and may search for keywords identifying an address. In one example, the calendar application searches for a zip code, city, alnd/or state name to identify an address, hi this manner, the calendar application identifi 3S that the geographic location of, for example, the first appointment 115 is at "1425 K Stn :et, NW, Washington D.C. 20005."

To identify the time associated with the appointment, in one implementation, the calendar application references a time field within the calendar appli cation to identify the time during which the appointment is scheduled to take place. Alter datively or additionally, the calendar application may reference other fields associated with the appointment and may search for keywords identifying time of each <. Appointment, hi one example, the calendar application searches for key words, such as ": tarting time," "ending time," "from 10:00am to 11 :00am," and other possible texts indicative of the time of the appointment, hi this manner, the calendar application id ϊntifies that the time associated with, for example, the first appointment 115 is from "10:00 am to 11 :00 am."

The process 1300 also includes the calendar application identifying participants of the appointment (1315). m one example, the calendar application searches participant field to identify the participants of the appointment. To this end, the calendar application identifies at least two participants (e.g., a first participant and a second participant). The first participant may be the owner of the calendar application referer bed in FIGS. IA and IB, for example.

After identifying the participants of the appointment, the calendar application identifies, at a time before the appointment time, a geographic location of one of the identified participants (1320). For example, the calendar applicatior identifies the geographic location of the first participant (e.g., the owner of the calendar application referenced in FIGS. IA and IB).

In some configurations, the calendar application automatical y identifies a geographic location of one of the identified participants at a predetermined time before the appointment. For instance, the predetermined time may be immediately preceding the appointment time or may be, for example, fifteen minutes prior to th e appointment. The predetermined time may be at a user-specified or a system-specified time in advance of the appointment time, hi other configurations, the calendar application identifies a geographic location of one of the identified participants in response to a user requesting the calendar application to identify the geographic location. An administrator, an appointment participant, an organizer of the appointment, or anothei j user related to the appointment may inspire the calendar application to identify the geographic location. For example, a first appointment participant may contact an assistant of a second appointment participant to determine whether the second appointment participan will be attending the appointment in person, by telephone, or whether a need exists to re; diedule the appointment. In this example, the assistant of the second appointment participant may inspire the calendar application to identify the geographic location of the second appointment participant to obtain the information requested by the first appointment participant.

In one implementation, the calendar application automatical y determines the present location of the first participant using location providing techjnology implemented in the client device of the first participant. If the client device is equipped with multiple location providing technologies, the calendar application may use : the technology that provides the more accurate information about the present location. JB o' ne example, the client device includes a mobile device that is GPS-enabled, and the i alendar application automatically determines the present location of the first participant based on the GPS position of the client device. In another example, the present location of the first participant is automatically determined by registering the client device with a host (e.g., a Session Initiation Protocol ("SIP")) server. The client device may p: fovide information to the host that is used to derive location information. For example, th host may derive location information based on how the client device is accessing the network (e.g., as identified by source IP address or another packet identifier).

In yet another alternative, the present location of the first participant is automatically determined from a profile associated with the first participant. The profile and/or contact information may indicate a predetermined home and/ar office location. In one specific example, the user of a client office computer has previously stored in his/her profile the location of the first participant's office. Thus, the calendar application uses the profile to determine the office location.

After identifying the geographic location of the first participant, the calendar application identifies a route extending from the geographic locatior of the first participant to the geographic location of the appointment (1325). Tc this end, in one example, the calendar application is equipped with navigation capabilities. Alternatively

FIG. 14 illustrates an exemplary process for identifying a travel time based on modality of travel. The calendar application identifies a modality o travel of the participant to the geographic location of the appointment (1410). Tc do so, in one implementation, the calendar application presents a UI to solicit, from the first participant, such information.

FIG. 15 illustrates an exemplary UI 1500 that is used to solicit, from the participant of the appointment, information regarding the modality cf travel. The UI 1500 requests that the first participant specifies or confirms the modality of travel and to this end presents to the user several options. The several options include walking, driving, public transportation, and others. The "others" option may be selected if the first participant's choice of travel does not appear among one of the walking, driving, or public transportation. For example, the user choice of travel may be via a bicycle. To this end, the selection of the "others" option generates another UI allowing the first participant to specify the modality of travel (e.g., a bicycle).

Referring again to FIG. 14, based on the modality of travel, tie calendar application identifies travel time associated with the route (1420). Ii identifying the travel time, the calendar application may take into account the speec of traveling. The speed of traveling may include an average speed based on the s i;pecified modality of travel or actual speed of travel. The calendar application may determine trjat actual speed of traveling by soliciting it from the user or automatically gleaning it from the client device.

To identify the travel time, the calendar application also may take into account traffic conditions. The traffic conditions may include current traffic flow or historic traffic flow. The current traffic flow maybe determined by contacting a server that includes traffic data to obtain current road conditions between the us er 's appointments,

Referring again to FIG. 13, the calendar application also identifies the amount of time remaining until the appointment time at which the appointment is due to start (1340).

The time remaining may be determined by identifying a present or current time and subtracting the present or current time from the starting time of the ppointment. Unless the present or current time is after the appointment time, the amount of time remaining until the appointment time is a positive number and may be used to determine whether the first participant is likely to arrive at the appointment on time.

Based on the time remaining until the appointment, the calendar application determines whether the travel time exceeds the amount of time remaining until the appointment (1345). For example, the calendar application may compare the travel time

potential conflict.

participant to change the current travel mode to a different one. Foi example, the first participant may be instructed to change the travel mode from public transportation to driving.

In a slightly different implementation, instead of the first participant having to select one of the options presented in the UI 1700, the calendar application automatically selects one of the options based on the user preferences. For examp Ie, upon determining that the first participant is running late to the appointment, the calenjdar application automatically sends a message to the other participants informing them that the first participant is running late along with the estimated arrival time. Fo: another example, upon determining that the first participant is running late to the appointment :, the calendar application automatically reschedules the appointment at a convenient time for the attending users. In yet another example, upon determining that the :jirst participant is running late to the appointment, the calendar application automa attiically informs the first participant to change the modality of travel and/or travel faster usin; the current modality of travel to timely arrive at the appointment location.

In some implementations, if it is determined that the travel time does not exceed the amount of time remaining until the appointment, further processing may be performed. For example, the calendar application may subtract travel time from the amount of time remaining until the appointment to determine the amount of time by which the first participant should leave to arrive at the appointment an time. The calendar application may compare the amount of time by which the first parti cipant should leave to arrive at the appointment on time to a threshold and, if the amount of time by which the first participant should leave to arrive at the appointment on time is ess than the threshold, the calendar application may send a reminder to the first articipant to remind the first participant to leave for the appointment. The reminder maj include the amount of time by which the first participant should leave to arrive at the ap iointment on time. hi some implementations, techniques described above with respect to FIG. 13 may be repeated. For instance, the techniques described with respect to TG. 13 maybe periodically repeated as the first participant travels to the appointment . In this example, updated information regarding the first participant's current location and the current time may be used.

In another implementation and as noted above, the concepts described herein also relate to a process for identifying that a user's appointment has been delayed and also for dynamically rescheduling the user's subsequent appointments to ac ount for such a delay.

FIG. 18 provides an example of such a process.

FIG. 18 illustrates an exemplary process 1800 used for dynamically rescheduling subsequent appointments of the user (e.g., the first participant) based on the determination that one of the appointments of the user (e.g., the first participant) h is been delayed. Some of the actions performed by the process 1800 are similar to th ; actions performed by the process 1300. As such and for purposes of brevity, these acti ms are not described here in more detail.

The process 1800 includes the calendar application identifyi: g an appointment within a calendar application (1805) and identifying an appointmen time at which the appointment is due to start and due to end (1810). The actions (180 > and 1810) are similar to those (1305 and 1310) described above with respect to th process 1300, and, as such, they are not described here in more detail.

The process 1800 also includes the calendar application iden tifying that the appointment has been delayed for a certain fixed amount of time (1 ! 15). For example, the calendar application identifies that the starting time of the appoi Ltment has been delayed due to one of the participants running late to the appointment. Alternatively or additionally, the calendar application may identify that the duration f the appointment has been extended beyond the scheduled ending time by a certain fh ed amount of time, For instance, in one implementation, one of the participants of the a] pointment notifies the calendar application of such delay. In another implementation, ttie calendar application determines such delay based on the locations of the part: ipants. For example, if the participant appears to still be at the location of the appointment instead of on the road traveling to the next appointment, the calendar applicati n determines that the appointment has lasted longer than previously scheduled.

Along these lines, the calendar application identifies the amc unt of time the appointment has been delayed and also identifies the subsequent apj ointments within the calendar application (1820). Based on the amount of time the appointment has been delayed and the timing of the subsequent appointments, the calendai application determines that a need for rescheduling other appointments exists ar d confirms with the participant the desire to reschedule the other appointments (1825). ^r[he calendar application then automatically reschedules the subsequent appointments within the calendar application such that the starting time of each of the subseqμent appointments is postponed to account for the delay associated with the current appointment (1830). The calendar application also may notify the participants of each of the subsequent appointments and inform them of such change, so that they can change their schedule according.

Other implementations are also contemplated.
