Description

200949203 IX. Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a navigation device and a method for operating a navigation device adapted to suit a user's workload. [Prior Art] Portable computing devices, such as portable navigation devices (PNDs) including Global Positioning System (Gps) signal reception and processing functionality, are well known and widely used as in-vehicle or other vehicle navigation systems. ❹ In general, modern PNDs contain a processor, memory (at least one of volatile memory and non-volatile memory, and usually both) and map data stored in the memory. The processor cooperates with the memory to provide an execution environment in which the software operating system can be built and, in addition, one or more additional software programs are often provided to enable the functionality of the PND to be controlled' and provide various other functions. Typically, such devices further include - or multiple input interfaces and/or multiple output interfaces that allow the user to interact with the device and pass the information relay to the use of the output interface By. Illustrative examples of output interfaces include visual displays and speakerphones for audio output. Illustrative examples of input interfaces include one or more physical buttons used to control the on/off operation or other features of the device (if the device is built into the vehicle, the buttons are not necessarily in the device itself, but rather It can be on the steering wheel and a microphone for detecting the user's words. In a particular configuration, the output interface display can be configured as a touch-sensitive display (by touch-sensing overlay or otherwise) to additionally provide an input interface by means of the input 135778.doc 200949203 interface 'user can The device is operated by touch. This type of device will also include one or more physical connector interfaces through which the power signal and the data nickname can be transmitted to the device interface. The device receives power and conditional data signals from the device; and, as appropriate, one or more wireless transmitters/receivers that allow for cellular telecommunications and other signal and data networks (eg, Bluetooth)

Communication over Wi-Fi, Wi_Max GSM, UMTS and similar networks. This type of PND also includes a GPS antenna through which satellite broadcast signals including location data can be received and subsequently processed to determine the current location of the device. The PND also includes an electronic gyroscope (3) pe that generates a g-ga and an accelerometer that can be processed to determine the current angular and linear acceleration, and in conjunction with the positional information derived from the GPS signal to determine the device and thus the installation. The speed and relative displacement of the vehicle of the device. Typically, these features are most commonly provided in in-vehicle navigation systems, but may also be provided in the pND (if this is advantageous). 0 The utility of these PNDs is mainly manifested in the fact that they determine the route between the first position (usually the starting or current position) and the second position (usually the destination). Such locations may be entered by the user of the device by any of a variety of different methods of 'for example, by postal code street name and house number (house _ber), previously stored "familiar" Land (such as famous locations, municipal locations (such as stadiums or swimming pools) or other points of interest) and favorite destinations or destinations that have recently been visited. This type of PND can be mounted on the dashboard or windshield of a vehicle but 135778.doc 200949203 can also be formed as part of the onboard computer of the vehicle radio or as part of the vehicle's own control system. The navigation device can also be a handheld system. A file such as a PDA (Portable Digital Assistant), a media player, a mobile phone, or the like, and in such cases, the conventional functionality of the handheld system is performed by placing the soft device on the device. The route calculation and the navigation along the route calculated by * are extended. During navigation along the calculated route, such PNDs often provide a view and/or audio command to direct the user along the selected route to the end of the route I, i.e., the desired destination. It is useful to direct the user to the end of the route (i.e., the desired destination) along the route of the selection. The PND also often displays map information on the screen during navigation, which is periodically updated on the screen to make the displayed map information represent the field location of the device and thus the current location of the user or user's vehicle (if The device is being used for in-vehicle navigation). The display displayed on the screen usually indicates the current device location and is centered, and is also displaying map information and other feature features of the current and surrounding roads near the current device location. In addition, depending on the situation, the navigation information may be displayed in a status column above, below or on one side of the displayed ground information. Examples of the navigation information include the distance from the current road that the user needs to select to the next yaw, and The nature of yaw 'this property can be represented by a further illustration of a particular class that indicates yaw (eg, a left turn or a right turn). The navigation function also determines the content, duration, and timing of the audible instructions by which the user can be guided along the route. For example, simple instructions such as "turning left after "moving kilometers" require a lot of processing and analysis. As previously mentioned, 135778.doc 200949203 user interaction with the device may be by touch screen, or otherwise or by a driverboard mounted remote control, by voice activation or by any other suitable method. Although the route calculation and navigation functions are important for the overall utility of the PND, it is possible to use the device purely for information display or "free driving", where only map information related to the current device location is displayed, and it has not yet been calculated Outbound - line and the device is not currently performing navigation. This mode of operation is often applicable when the user is aware of the route along which the trip is to travel and does not require navigation assistance. ® Devices of the above type (for example, Model 920T manufactured and supplied by TomTom International BV) provide a reliable way for users to navigate from one location to another, when users are unfamiliar with the navigation to them These devices have great utility when routed to the destination. As mentioned above, the memory of the PND stores map data that is used by the PND to not only calculate the route and provide the necessary navigation instructions to the user, but also to provide visual and audible to the user via the visual display of the PND. Information. Road safety is a major consideration in automotive applications. However, despite the introduction of safety features such as the anti-lock braking system (ABS), driver drivers are at fault - still responsible for many car accidents. • Using PND to navigate increases the safety of the custodian compared to using instructions written on paper or not using instructions at all. It reduces the subjective and objective work of the driver and the driver feels less pressure. However, it is desirable to further increase the safety of the driver. 133778.doc 200949203 According to a first aspect of the present invention, a navigation and/or mapping device is provided, the navigation and/or mapping device comprising a processing resource and operatively coupled to the processing resource At least one communication device for communicating with a user configured to determine a workload of the user and to provide or change communication with the user depending on the workload of the user.

[Embodiment] The same reference numerals will be used throughout the following description to identify similar parts. Embodiments of the present invention will now be described with particular reference to PNDs. However, it should be borne in mind that the teachings of the present invention are not limited to PNDs, but are generally applicable to configurations that are specifically portable to perform software in order to provide map capture, route planning, and/or navigation functionality. Any type of processing device. Therefore, it can be seen that, in the case of the present application, the navigation device is intended to include, but is not limited to, any type of route planning and navigation device, whether the device is embodied as a PND, a vehicle such as a car, or actually a ship. Portable computing resources for performing route planning and navigation software (eg, portable personal computers (PCs), mobile phones, or personal digital assistants (PDAs)). It will also be apparent from the following that the teachings of the present invention are effective even when the user does not seek guidance on how to navigate from one point to another, but only if it is desired to provide a view of a particular area. In such cases, the "destination" location selected by the user 135778.doc -18- 200949203 does not have to have the corresponding departure location from which the user wishes to navigate, and therefore, in this article, • destination "Location or actual reference to the "destination" view should not be interpreted as meaning that the route is required, travel to "destination" must occur, or indeed the existence of the destination needs Specify the appropriate starting location. The above conditions are attached, and the Global Positioning System (GPS) of Fig. 1 and the like are used for various purposes. In general, GPS is a satellite-based radio navigation system that determines continuous bits of information, speed, time, and (in some cases) direction information for an unlimited number of users. The GPS, formerly known as NAVSTAR, incorporates a plurality of satellites orbiting the earth in extremely precise orbits. Based on these precise orbits, GPS satellites can relay their position to any number of receiving units. A GPS system is implemented when a device specially equipped to receive GPS data begins scanning for a radio frequency for a GPS satellite nickname. After receiving a radio signal from a GPS satellite, the device determines the exact location of the satellite via a plurality of different conventional methods. In most cases, the device will continue to scan the nickname until it has obtained at least three different satellite signals (note that 'usually not (but can) use other triangulation techniques to determine position by only two signals ). After performing the geometric triangulation, the receiver uses its two known locations to determine its own two-dimensional position relative to the satellite. This determination can be made in a known manner. In addition, obtaining a fourth satellite signal allows the receiving device to calculate its three-dimensional position in a known manner by the same geometric calculation. Location and speed data can be updated instantly by an unlimited number of users. As shown in Figure 1, the GPS system 100 includes a plurality of 135778.doc • 19-200949203 satellites 102 that operate around the earth 104. The GPS receiver 106 receives the spread spectrum GPS satellite data signal 108 from a plurality of satellites of the plurality of satellites 102. The spread spectrum data signal 108 is continuously transmitted from each satellite 102, and the transmitted spread spectrum data signals 1 〇 8 each include a data stream identifying a particular satellite 102 from which the data stream originates. The GPS receiver 106 typically requires spread spectrum data signals 1 〇 8 from at least three satellites 102 to enable calculation of two dimensional positions. The receipt of the fourth spread spectrum data signal enables the GPS receiver 106 to calculate the three dimensional position using known techniques.

Doc -27- 200949203 The navigation device 200 is operable to determine the workload of the user and to vary the requirements imposed by the device 200 on the user accordingly. In this regard, device 200 is adapted to receive input indicative of physiological factors 6.2, psychological factors 604, behavioral factors 606, external factors 608, interaction factors 610, and historical factors 611 as shown in FIG. These factors 602 through 611 are registered in the memory 612 of the device 2 and used to determine the user profile 614. The user profile slot 614 is dynamically updated in real time to keep the profile 614 current and relevant. Monitoring user data file 614 over time and using it to determine the user's current workload" change in data flag 614 may indicate an increase or decrease in the user's workload. The user's workload is then compared to a predetermined threshold to determine if the user's workload is abnormally high (i.e., the user may be under stress) or abnormally low (i.e., the user may be fatigued). Device 200 then adjusts its interaction with the user 616 accordingly to account for the user's workload. The device 2 is shown in more detail in FIG. It will be appreciated that those skilled in the art may select only the described components or factors used in the practice of the device or some of the alternative components or factors not described herein. Device 200 includes a processor 702 coupled to memory 612. The memory 612 is configured to store map throttle and navigation data 〇4 and also to store user profile 614. Apparatus 200 is coupled to input members 708 through 718 for collecting information indicative of factors used to determine the workload of the user. Such input components include physiological sensor 708, microphone 71, user input device 712, link 714 to a remote repository, wireless signal receiver 716 (such as a BluetoothTM receiver and a mobile phone signal receiver) And camera 135778. Doc •28- 200949203 718. The device also has output devices such as a display 72, a vibration alert device 722, and an audio output device 724. Input device 712 and display output device 720 are optionally incorporated into a single device, such as a touch screen display. Physiological sensor 708 is adapted to measure physiological characteristics of the user, such as heart rate, blood pressure, and skin electrical response. The sensor 7〇8 is mounted on the steering wheel of the vehicle. The user's hand then contacts the steering wheel and thus the sensor 7〇8 in a manner suitable for collecting the above physiological parameters in an unobtrusive manner. In an alternate embodiment, the physiological sensor is mounted in other portions of the vehicle or mounted on other portions of the vehicle and/or attached to the user's body. The physiological characteristics of the user are recorded over time and used to create a physiological sub-profile of the user as part of the user's data file 614. The physiological data file therefore contains typical parameters or ranges of changes in the physiological conditions of the user. It can then be seen whether the most recent physiological parameter is outside the normal parameter range of the user or at the limit of the normal parameter range of the user. This information is cross-referenced with information indicating other user-related factors (such as traffic data, psychological parameters, driving behavior, etc., as described below) to increase the accuracy of the workload determination by the device. By comparing the recently measured physiological data with the historical data stored in the user's data file 614, it can be seen that the physiological data indicates an abnormal increase or decrease in the user's workload. This determination is then taken into account in conjunction with other factors contained in the user's profile to determine the user's current workload" 135,778. Doc -29- 200949203 Device 200 is also adapted to collect, store, and update the psychological sub-data files that are part of the user's profile 614. The mental data file is used to determine the user's workload in conjunction with other sub-data files in the user's data file 614 and user-related factors. Psychological data files also provide calibration data that can be used, for example, to set workload thresholds at which the device will initiate pressure-related or fatigue-related actions. The mental data file is constructed using input device 712 to receive subjective input from the user in response to the setting question. Examples of suitable input devices include touch screens, keyboards, buttons, roller balls, soft keys or virtual keys or a keyway to a personal computer. In one embodiment, as shown in Figure 8, the interface 8〇2 is presented via a personal computer to allow the user to provide subjective input for creating a user's psychology profile. Interface 8〇2 is operable to present prompts 804 and questions 806 to the user and to obtain input from the user indicating personal preferences and characteristics. Examples of such preferences include the importance of security to the user and whether the user is a thrilling explorer or risk averse. _ The interface is also configured to prompt and obtain input from the user regarding the user's perceived driving style. The device is provided with a communication module (for example, a USB port or a Wi-Π device) to allow the device to be linked to the personal computer to transfer the details of the collected data from the computer to the device. Display 720 of device 200 is also configured to present a user interface 902 (shown in FIG. 9) to the user via a touch screen, the interface 902 being operable to collect feedback input 904 from the user, such as the user discovering a particular The degree of stress in the situation or journey or the type of vehicle the equipment is suitable for. Device 200 is configured to calibrate the device with subjective input and feedback, 135778. Doc -30- 200949203 and in detail, set or change the threshold for the device 200 to implement anti-stress or anti-fatigue measures. Another example of material available in this manner is the vehicle type. The device 200 is configured to incorporate this information into the user's data slot 614 and may incorporate adjustments as an important factor to suit the vehicle, for example, by installing the device 200 in a slower than normal vehicle (such as ' In the truck), change the definition of device 2〇〇 to low speed. In addition, device 2 is adapted to provide improved problems depending on earlier feedback', e.g., when the vehicle is heavier, do you want to avoid small roads". As shown in Figure 7, the navigation device 200 is equipped with a positioning system 726, such as a GPS system or a mobile communication network triangulation system, for determining the current position of the vehicle. The device 200 is adapted to use the location information in conjunction with the mapping and navigation information 704 stored in the data store or memory 612 to monitor the user's driving behavior. In an alternative embodiment, the device 2 is connected to a car system (such as a 'speedometer or tachometer) or to an additional navigation sensor (such as an 'accelerometer'). This directly measured data is supplemented or cross-referenced by information about external factors obtained from server 728 or remote or centralized databases 730 through 734 or stored in delta memory 612 of device 200. This external factor information includes the historical average or typical speed of the current road segment, the current average speed of traffic on the road segment, and traffic reports indicating congestion and traffic congestion. The driver's behavior is incorporated into the user's psychological data rights 614 and used to establish a record of the user's driving style. Then compare the currently determined driver's behavior with the user recorded in the user's data file 614 135778. Doc -31- 200949203 Typical driving behavior to determine if the user is acting in line with the user's usual behavior. This consistent behavior can indicate the stress of fatigue.仃 For example, Driver A is a calm and relaxed person whose workload is relatively constant. Driver B is a tight A and his workload varies considerably during the line. Because &, A's user profile does not change much over time, and Driver B's user profile changes over time (this information indicates the variability of the user profile itself) Or instability) can be used as input to the user profile to ensure that the system (based on the user profile) is properly adapted, and a sudden change (steering wheel adjustment) is rare for driver A and therefore for the workload An important indicator of sudden rise. Conversely, for driver B, this maneuver is normal 'and if it does not happen' it indicates fatigue. Therefore, the history of the user profile (the extent of its variable/unstable) can be used to make more accurate work decisions. Examples of external factors or driver behavior that may indicate pressure or fatigue include: the user is in a traffic jam, the user is performing a lot of u-turns, the user is causing road congestion and slowing the traffic behind, the user's yaw planning The route, the user looks around, the user makes a U-turn, or the user drives backward. As an example of device usage for driver behavior, the positioning system 726 of the device 200 is operable to monitor changes in the user's position over time and thereby determine the speed of the device 200. The communication module 714 of the device 200 is operable to obtain from the server 728 the historical average or typical speed of the current road segment or the current average speed of traffic on the road segment (e.g., as self-interested 135778. Doc -32· 200949203 The flow measurement device or information system 730 is determined by monitoring the location and time of other road users (via their mobile phone signals). Apparatus 200 is then configured to compare the speed of the user to the average speed of the surrounding traffic and the historical average traffic speed of the road segment. This may indicate pressure if the user's speed is greater than the average speed of traffic around it or slower than the historical average speed of the road segment. This can indicate fatigue if the user is slower than the average speed of traffic around him. The historical relative user speed data in the user profile 614 can be cross-referenced with the user's current speed and the average speed of the surrounding traffic and the historical average traffic speed of the road segment and used for the analysis of the current data. For example, if the user typically drives at a slower rate than the average speed of traffic around them, the user speed is less than the average speed and the safety is less than when the user typically drives at an average traffic speed or above the average traffic speed. Sexual problems. The map material 704 is also stored in the memory 612 of the device 200, in the remote data storage or feeder 728, or via a remote repository or information service 732. The presence of a potentially stressful situation from map data 704 is included in the user's data broadcast 614 as an important factor and is also used to determine the user's workload. Examples of potentially stressful situations that can be identified based on map data 7〇4 include: many roads converge, densely populated areas, roads that act as acceleration and deceleration lanes, and well-known accident black spots, Road intersections, areas with normally busy traffic, changes in road types, changes in speed limits, historical average speeds of traffic that are lower than the maximum speed, or the difference between the maximum speed and the historical average speed, showing the sudden drop of the road, crossing other The road has priority 135778. Doc 33- 200949203 Road, close to the sidewalk area, close to a sharp turn or close to a school or place of worship. The sigh can also be identified by 纟 #he indicates that the driver may be easy > the heart or its work load is over two factors. For example, the equipment is adapted to determine if there are passengers on the vehicle. For example, by using the device 2's Bluet〇〇thTM receiver 716 to detect the number of Bluetooth devices within a specified radius, the camera 718 is used to detect the passenger, or by being placed in the car seat. This determination can be made by connecting the weight sense to the 'facet'. The microphone 710 can also operate to beta other passengers, for example, by detecting a child's shouts or conversations. " Also provided is at least one camera 718 operable to monitor the user, the interior of the vehicle, and the location and environment of the vehicle. The camera 718 is used to obtain stress or fatigue by, for example, detecting when the vehicle is not in the lane and when the surrounding traffic is slowing down by monitoring what the user is looking at and watching for how long and detecting the presence of the passenger. Visual indication. The equipment has also been adapted to monitor the time the user has driven. This monitoring can be used, for example, by using the positioning module of the device to detect the movement of the driver's position, by monitoring the time since the user provided "start navigating" input or by monitoring the vehicle ignition. Long driving times can be used by the equipment as an added pressure factor. In addition, the device is adapted to obtain information about other influential stress factors, such as adverse weather, via links to the remote repository 734 and/or server 728. This information can also be included in the user's data file 614 as an important factor. The device 200 is adapted to collect variables that form the user's data file 614 and 135,778. Doc •34· 200949203 Update it as appropriate. The algorithm is used to analyze the entire data file 614 to confirm the user's workload. As described above, the workload is determined by comparing current factors with historical data of the route, mental data files, typical data, and information from other sources, such as traffic and weather data. A more accurate workload determination can be performed by using a data file 614 that indicates the distribution of factors that are mutually referenced. The use of this profile technology is particularly advantageous in navigation devices because the existing components and functionality of the device (as described above) can be used to derive parameters for constructing user profiles, thereby reducing the formation of data files 214. burden. The user's workload can indicate pressure (i.e., what is working above a predetermined threshold) or fatigue (i.e., a working negative below a predetermined threshold). The threshold is determined using the information obtained (such as 'user's answer to subjective questions, historical data to determine baseline or normal response, and other factors as described above). Device 200 is adapted to change its communication 616 with the user depending on the determination of the workload. By accurately determining the workload (by using user profiles) and by setting the appropriate thresholds, the device 200 is better able to detect pressure and fatigue and avoid responding to erroneous determinations. Frequent Changes - The changes provided by the device to the communication can be slight and subtle. Subtle communication changes combined with the rare changes make the changes more noticeable and effective in countering stress and/or fatigue. The change in communication involves the device 2 adapting its communication and interface to present information in a more concise manner. As an example of adaptation of the communication provided by device 200, device 2 may limit the number of instructions to the user. Device 200 can also be adapted to provide 135778. Doc -35- 200949203 specific warnings ' instead of using instructions to start communication, for example, by using "Note. ···(note. . . . . . Or "Please note. . . . . . (Attention...·. )" to start communication instead of using something like "in front". . . . . . (Ahead...)" or " within XXX meters... (In XXX metres.... . )" instructions to start communication, or by adding a warning such as "and pay attent;i〇n" after the reference. Another example of a communication change is an audible warning after the instruction, such as a short command or sound. This is particularly suitable for use when device 2 has determined that the user is tired. Another example of adaptation of communication of device 200 is to configure the device to issue an instruction to the user to stop driving or interrupting. As another example, the audio output device 724 of the navigation device 200 is configured to vary the pitch, pitch and/or speed of the spoken output depending on the determination of the workload. In this way, the device 200 can adapt to the pressure on the user by making the voice sound easier, and the device 2 can adapt to the user's fatigue by making the voice sound less easy and more urgent. Dish set. Other examples of communication changes that may be used include activating the vibration unit 722 to provide a vibration warning to the user, deactivating non-essential items from the display 720 (such as unnecessary ροι), and adjusting the zoom level of the display 720. If the workload is high, the zoom on display 720 can be adjusted to reduce the perspective. 10 shows an interface 1 〇 02 of the device 200 to display the user's destination in a compass style representation by using a limited portion of the display 72 (such as the top 2 or 3 pixels of the screen of the display). Provide an example of a more concise output. For example, if the destination is in front of the device 2, to the right of the device 200, or to the left of the device 200, the destination may be at the center 1008 of the screen, the left side 1〇1〇 or the right side 1012 of the destination area 135778. . Doc -36 - 200949203 is shown as (4) pictogram 1 〇〇 6. The portion of the display used to indicate the direction to the left or right when the destination is indicated in the direction (eg, center) can be used to display other information 1〇14, such as (when appropriate), the incoming thing ( For example, the image of a bridge or water, the number of kilometers before the train crossing the road to the road to the road, or the number of kilometers until the destination will or will not be in front. Camera 718 is also used in the modification of the communication of device 2. For example, if the camera 718 detects the car in front and the device 2 determines that the user should follow the car in front of the car, then the representation of the car can be projected into the driver's field of view for the driver to follow the displayed Cars, thereby providing less stressful communications. Camera 718 is also adapted to monitor the relative position of the vehicle in the vicinity of the user's vehicle. If the user's vehicle is too close to an adjacent car, the device 200 is adapted to provide the appropriate instructions. For example, if the user's vehicle is too close to the car in front, the user is instructed to decelerate (sl〇w d〇wn)". _ If the device determines that the user's pressure level is above a certain threshold or the user is approaching a stressful condition, the device 2 is adapted to drive the car by interrupting the interaction between the user and the device 200. Alert. When device 2 is in the interrupt mode, input device 712 of device 200 is adapted to receive the appropriate predefined recovery input from the user' and resume the learned communication upon receipt of the resume input. After receiving the recovery input from the user, the device 2 is adapted to assume that the user's workload is not as high as expected, and that the threshold for determining pressure or fatigue can be appropriately raised or adjusted. Device 2〇〇 is then configured to evaluate the user's data file against the new threshold until 135778. Doc •37· 200949203 The predetermined criteria have been met, for example, until the device 200 displays the driving view again 'or until the set time has passed' or until the user's data file 6U has exceeded the new threshold. Historical user profile data can be used to provide a record of changes in the user's workload across the road network. This can be used to form a data map. This can be used in a variety of applications, such as government organizations to improve road networks (by providing guidance on which roads are used and which are the most dangerous). Business organizations can use this information to best address the placement of advertisements. This information may also be provided to the PND in the form of a data map to provide a map showing areas of stress or to construct other user data files.
