Specifically, the user state score calculation unit 171 may determine the necessity of notification information for the user for each of these items, and calculate the user state score as a total value of scores indicating the necessity for each item. it can.

The user state score calculation unit 171 provides the calculated user state score to the notification method determination unit 180. Note that the user state score calculation process by the user state score calculation unit 171 will be described in detail with a specific example in the following (2. User state score calculation process).

The information importance score calculation unit 172 calculates an information importance score representing the importance of the notification information based on the property information. For example, the information importance score calculation unit 172 calculates the information importance score of the notification information that is the object to be notified now, based on the property information including the time information and the position information when the notification information is acquired. .

The property information used for calculating the information importance score includes, for example, “time”, “location”, “past habit”, and “information freshness” exemplified in the following (3. Information importance score calculation processing). And information indicating “alternative means” and the like may be included. The information importance score calculation unit 172 can calculate an information importance score based on these items included in the property information. Specifically, the information importance score calculation unit 172 can determine the importance of the notification information for each of these items, and can calculate the information importance score as a total value of scores indicating the importance in each item. .

The information importance score calculation unit 172 provides the calculated information importance score to the notification method determination unit 180. The information importance score calculation processing by the information importance score calculation unit 172 will be described in detail with a specific example in the following (3. Information importance score calculation processing).

The notification method determination unit 180 determines a notification information notification method for the user based on the user information and the property information. Specifically, the notification method determination unit 180 may determine a notification information notification method for the user in a plurality of devices associated with the user based on the user state score and the information importance score. it can. Here, in the present embodiment, as a notification method, a device that notifies the user of notification information (hereinafter also referred to as a notification device) and a notification unit in the notification device are determined. In the notification device determination process, one or a plurality of devices used for notification may be selected from a plurality of devices associated with the user. Of course, all devices may be selected. On the other hand, in the notification unit determination process, the notification unit in the notification device selected in the notification device determination process can be selected. Here, the notification means includes a type of information to be notified (for example, information indicating that the notification information has been acquired, a part of the content of the notification information, all of the content of the notification information, etc.), and a specific method for notifying (For example, vibration, sound, light from a lamp, display on a display screen, etc.).

The notification device can be determined based on user information. For example, in the notification device determination process, the notification method determination unit 180 determines the notification device so that the user is gradually alerted that the notification information has been acquired as the user state score increases. For example, when the user state score is low, it is considered that the necessity of notifying the user of the notification information is low. Therefore, the necessity for notifying the user that the notification information has been acquired is low. Therefore, the notification method determination unit 180 selects a smaller number (for example, one) of devices from a plurality of devices associated with the user. On the other hand, when the user state score is high, it is considered that the necessity of notifying the user of the notification information is high. Therefore, it is necessary to make the user more surely notice that the notification information has been acquired. Therefore, the notification method determination unit 180 selects a larger number (for example, all) of devices from a plurality of devices associated with the user. As described above, the notification method determining unit 180 can change the number of notification devices based on the user information.

Further, the notification method determination unit 180 may determine a notification device based on the device information provided from the device information acquisition unit 153. For example, a device that is determined not to be possessed by the user from the device information cannot be selected as a notification device. Even if the device is owned by the user, the device is turned off, prohibited from being used as a notification device in individual settings on the device, or when the user logs into the device If a situation such as not being determined is determined based on the device information, those devices are also preferably not selected as the notification device.

On the other hand, the notification means can be determined based on the property information. For example, in the notification unit determination process, the notification method determination unit 180 determines the notification unit so that the content of the notification information is gradually notified to the user as the information importance score increases. For example, when the information importance score is low, it can be said that the notification information is information having low importance for the user. Therefore, it is not necessary to notify the user of the contents of the notification information. Therefore, the notification method determination unit 180 selects a notification unit that notifies only that the notification information has been acquired, for example, does not notify the content of the notification information, such as vibrating the device or lighting the lamp. To do. On the other hand, when the information importance score is high, it can be said that the notification information is information that is highly important to the user. Therefore, it is preferable that the content of the notification information is quickly notified to the user. Therefore, the notification method determination unit 180 selects a notification unit that can notify the user of the content of the notification information, for example, audibly and / or visually. Thus, the notification method determination unit 180 can change the information amount of the notification based on the notification information based on the property information.

Here, as described above, the user information acquisition unit 152 acquires, as user information, information indicating the current user status (for example, sleeping in a train, working at a company, driving a car, etc.). Can do. Information indicating the status of the user may be provided from the user information acquisition unit 152 to the notification method determination unit 180. Then, when it is estimated that the user's situation is a specific situation based on the information indicating the user's situation, the notification method determination unit 180 determines a predetermined notification method, for example, a user's situation. A notification method that reduces the amount of information to be notified may be determined. For example, when the user is wearing a glass-type device or an HMD device, and when it is estimated from the user information that the user is driving a car, the user status score or Regardless of the value of the information importance score, the notification method for visually notifying information such as displaying the notification information on the display screen of the glass-type device or the HMD should not be executed. Therefore, for example, when it is estimated that the user is driving a car, the notification method determination unit 180 selects a relatively small number of notification devices or visually determines so as not to distract the user. It is possible to select other notification means that are not typical notification means. Note that the process of changing the notification method that can be determined by the original user state score and the information importance score to a predetermined notification method is, for example, the user state score so that the predetermined notification method is selected. In addition, it may be realized by appropriately correcting the information importance score.

As described above, the notification method determination unit 180 can determine a more appropriate notification method according to the quality of the notification information and the current state of the user based on the information importance score and the user state score of the notification information. it can. The notification method determining unit 180 determines the notification device determined by the notification device determination process (this includes the information device itself (the information processing apparatus 10 in the example illustrated in FIG. 1)) by the notification unit determination process. Information about the notified means and notification information are transmitted.

A device that has received information about notification means and notification information from the notification method determination unit 180 drives an output unit (for example, a vibration element, a sound output device, a display device, etc.) included in the device according to the notification means. Notification information is notified to the user. Thereby, the notification information can be notified to the user by an appropriate notification method determined by the notification method determination unit 180. For example, in the example illustrated in FIG. 1, if the information processing apparatus 10 and the device 20 are selected in the notification device determination process, a configuration corresponding to the output unit 120 of the information processing apparatus 10 and the output unit 120 of the device 20. On the other hand, information about the notification means determined in the notification means determination process is transmitted. And the structure corresponding to the output part 120 of the information processing apparatus 10 and the output part 120 of the device 20 drives according to the determined notification means, and notification information can be notified to the user. The notification method determination process by the notification method determination unit 180 will be described in detail with a specific example below (4. Notification method determination process).

In the present embodiment, the notification method determination unit 180 may have a function of determining whether the acquired notification information is information to be notified to the user according to a predetermined standard. For example, when a user uses a plurality of different information distribution services, notification information having the same content may be distributed at almost the same timing. For example, in the acquired notification information, the notification method determination unit 180 can determine that the notification information whose content overlaps with the notification information already notified to the user is not information to be notified to the user. . Alternatively, the notification method determination unit 180 is a case where notification information of the same type as the notification information notified to the user in the past is acquired, and the user does not confirm the content of the notification information at the time of the past notification. If it has been discarded, the newly acquired notification information can be determined not to be information to be notified to the user. At this time, only when the user information such as the location, time, and user status is the same as the user information at the time of notification of the past notification information, the notification information should be notified to the user according to the past user behavior. It may be judged. This is because when the same type of notification information is acquired when the user is in a similar state, it is predicted that the user will take the same action as the action taken in the past. The notification method determination unit 180 stores the determination whether the acquired notification information is information to be notified to the user, for example, stored in the storage unit 130 so far, which has been notified to the user. It can be executed by referring to the history of information and its notification method.

When the notification method determination unit 180 determines that the acquired notification information is not information to be notified to the user, the notification information is not notified to the user, and the information processing apparatus 10 Wait until is delivered. In this case, the property information acquisition unit 160 as described above acquires property information, the user state score calculation unit 171 calculates the user state score, and the information importance level score calculation unit 172 calculates the information importance level score. It does not have to be.

The configuration example of the information notification system 1 according to the present embodiment has been described above with reference to FIG. In addition, the apparatus structure which comprises the information notification system 1 is not limited to the example shown in FIG. For example, each function of the information processing apparatus 10 illustrated in FIG. 1 does not necessarily have to be integrally mounted on one apparatus. Each function installed in the information processing apparatus 10 shown in FIG. 1 is distributed and installed in a plurality of devices (for example, a plurality of devices owned by a user), and the plurality of devices are connected to each other via a network. By doing so, the information notification system 1 may be configured. For example, each function of the control unit 140 may be executed by one processor or may be executed by cooperation of a plurality of processors.

Further, it is possible to create a computer program for realizing each function of the information notification system 1 according to the present embodiment as described above and mount it on a personal computer or the like. In addition, a computer-readable recording medium storing such a computer program can be provided. The recording medium is, for example, a magnetic disk, an optical disk, a magneto-optical disk, a flash memory, or the like. Further, the above computer program may be distributed via a network, for example, without using a recording medium.

As described above, according to the present embodiment, the notification method based on the notification information is determined based on the user state score indicating the user state and the property information indicating the property of the notification information. Therefore, the notification information is notified to the user by a more appropriate notification method according to the state of the user and the content of the notification information.

Here, as a general existing technique, for example, using information such as time, place, user action log, etc., notification information that the user is likely to need at that place is appropriately sent to the user. A technique for notifying has been devised (see, for example, Patent Document 1 above). However, in the existing technology, the nature of the notification information is not taken into consideration, and according to the nature of the notification information, the type of device that notifies the user of the notification information and the notification information notification means in the device No changes have been made.

However, the notification information that can be provided to the user has various contents such as information that is required immediately and information that can be used if confirmed later. In the existing technology as described above, any notification information is treated uniformly and is notified to the user by a certain notification method. Therefore, it is impossible to determine whether the notification information is information that is necessary immediately or information that can be confirmed later. Therefore, for the user, an operation for confirming the content of unnecessary notification information is urgently generated, and the convenience is low.

On the other hand, according to the present embodiment, as described above, the notification information is notified to the user by a more appropriate notification method according to the state of the user and the content of the notification information. For example, if it is information that is not necessary for the user to check immediately (that is, information with a low user status score), a notification method is selected that does not remind the user that the notification information has been acquired more than necessary. Can be done. In addition, if the information is low in importance to the user (that is, information having a low information importance score), a notification method in which notification information is notified with a smaller amount of information can be selected. Therefore, the user does not need to confirm the content of the notification information, and when the notification information is received, the user only takes a glance at the display related to the arrival of the notification information. And whether it is important information can be determined. Therefore, the convenience of the user when acquiring various information can be improved.

Hereinafter, in (2. User status score calculation process), (3. Information importance score calculation process) and (4. Notification method determination process), the above-described user status score calculation unit 171 and information The functions of the importance score calculation unit 172 and the notification method determination unit 180 will be described in more detail.

(2. User status score calculation process)
As described above, the user status score calculation unit 171 includes information indicating “time”, “location”, “user status”, “device status”, and the like included in the user information acquired by the user information acquisition unit 152. Based on the above, the necessity of the notification information for the user for each of these items can be determined, and the user state score can be calculated as the total value of the scores indicating the necessity for each item. However, the items listed here are merely examples, and the user state score calculation unit 171 may calculate the user state score based on other items.

“Time” and “Location” respectively indicate the time when the notification information is acquired and the location of the user (that is, the time when the notification based on the notification information is performed and the location of the user). For example, the user information acquisition unit 152 performs notification in the form of a period such as morning, noon, night, etc. based on the time information provided from the time / position information acquisition unit 151 when the notification information is acquired. Information indicating the time when the information is acquired can be acquired as user information. Further, for example, the user information acquisition unit 152 provides information indicating the user's location based on the user's location information provided from the time / position information acquisition unit 151 when the notification information is acquired. Information indicating where the information processing apparatus 10 and the device 20 are currently used, such as outdoors, indoors, in a car, or outside a car, can be acquired as user information. The information indicating the location of the user may include information on a more detailed location where the user may exist, such as a home or a company. The user status score calculation unit 171 may determine the necessity of the acquired notification information for the user based on information indicating the time when the notification information is acquired and the location of the user included in the user information. it can.

“User status” includes, for example, notification information including a user's movement status such as walking or riding on a vehicle, stopping at one place, and a user's physiological status such as sleeping or getting up. Shows every situation of the user when acquired. For example, the user information acquisition unit 152 can acquire information indicating the movement status of the user as user information based on the sensor information provided from the sensor unit 110. Further, for example, the user information acquisition unit 152 obtains information about the user's physiological status (for example, information indicating whether the user is currently sleeping or waking up) based on the sensor information. It can be acquired as information. The user state score calculation unit 171 can determine the necessity of the acquired notification information for the user based on information indicating the user status included in the user information.

“Device state” indicates the driving state of the device, for example, during charging, during normal driving (ie, in use), or in standby. For example, the user information acquisition unit 152 can acquire information indicating the state of the device as user information based on the device information provided from the device information acquisition unit 153. Information that shows the status of the device is whether the user is currently giving up the device, is in the process of using it, is in possession but not in use, Can be a material for judging. When the user has a plurality of devices, for example, if any one of the devices is normally driven, the “device state” may be determined as being normally driven. When any of the plurality of devices is charging or waiting, the “device state” may be determined as charging or waiting, respectively. As described above, the information indicating the state of the device may be information indicating whether the user is using any one of the devices. The user state score calculation unit 171 can determine the necessity of the acquired notification information for the user based on information indicating a device state included in the user information.

The user information acquisition unit 152 further refers to the user's past action log, the user's schedule information, and the like stored in the storage unit 130 when acquiring the information related to each item described above as user information. Also good. For example, if the user's behavior at a predetermined time can be predicted from the behavior log and schedule information, the user information acquisition unit 152 is not inconsistent with the provided time information, position information, sensor information, and device information. User information may be acquired based on user behavior predicted from behavior logs and schedule information.

Here, an example of a specific situation will be given and the user state score calculation processing by the user state score calculation unit 171 will be described in more detail. For example, “time” is divided into “morning”, “daytime”, and “night”, “location” is divided into “inside”, “outdoor”, and “indoor”, and “user situation” is “moving + getting up” ”,“ Moving + Sleeping ”,“ Stopping + Waking up ”,“ Stopping + Sleeping ”, and“ Device status ”as“ Standby ”,“ Normal driving ”,“ Charging ” Consider a separate case. For example, scores of 0 to 5 points are set for these items as follows.

(Times of Day)
Morning: 2 pt.
Daytime: 1 pt.
Night: 3 pt.

(place)
Inside the car: 4 pt.
Outdoor: 4 pt.
Indoor: 1 pt.

(User situation)
Moving + Waking up: 4 pt.
Moving + sleeping: 5 pt.
Stopping + waking up: 3 pt.
Stopping + sleeping: 1 pt.

(Device status)
In standby: 3 pt.
During normal driving: 4 pt.
During charging: 2 pt.

Note that these scores are merely examples, and specific values of scores set for each item may be arbitrarily set. For example, these scores can be set as appropriate so that an appropriate notification method is determined based on the past action log of the user. For example, from the user's past action log, if the frequency at which the user confirms notification information in the night time zone is higher than in other time zones, the score of “time” at “night” is It can be set higher than the score at other times. Alternatively, these scores may be set as appropriate by the user so that the notification method desired by the user is realized. For example, if the user wants to be notified of notification information at night time more than other time zones, the user can score the “time” score at “night” at other times. It can be set higher than the score.

In the above example, the score is set for the “device state” according to the following concept. That is, the score is set low when the device is being charged. When the device is being charged, it is estimated that the user is not using the device and is performing other work, so there is no need to notify the user of notification information. This is because it is considered low. For example, when the device is normally driven, the score is set high. This is because when the device is normally driven, the user is presumed to be using the device, and therefore it is considered highly necessary to notify the user of the notification information. Further, for example, when the device is waiting, the score is set to a medium level. When a device is waiting, it is estimated that the user is in possession of the device but not in use, so the need for notifying the user of notification information is moderate This is because it is considered. However, the concept of score setting for these “device states” is merely an example, and the specific score setting may be changed as appropriate according to the actual situation of the user.

The user status score can be calculated as the total score of each item when the notification information is acquired. For example, the user status score of a user who has fallen asleep on the last train is: time: night: 3 pt. Location: Inside the car: 4 pt. User situation: moving + sleeping: 5 pt. Device status: Waiting: 3 pt. , Becomes a total of 15 points. Therefore, in this example, when the notification information is acquired, the user state score calculation unit 171 calculates the user state score of the user who has fallen asleep on the last train as 15 points.

Thus, in this embodiment, in addition to the time when the notification information is acquired and the location of the user when the notification information is acquired, the user status score, the user's past action log, and the user's situation And can be calculated based on the state of the device. Therefore, the user state score taking into account the user's usual habits is calculated, and the necessity of the notification information for the user can be more accurately reflected in the calculated user state score.

(3. Information importance score calculation process)
As described above, the information importance score calculation unit 172 includes the “time”, “location”, “past habit”, “information freshness”, and “alternative” included in the property information acquired by the property information acquisition unit 160. Based on the information indicating “means” or the like, the importance of the notification information can be determined for each of these items, and the information importance score can be calculated as the total value of the scores indicating the importance of each item. However, the items listed here are merely examples, and the information importance score calculation unit 172 may calculate the information importance score based on other items.

As in the case of the user status score, “time” and “location” are the time when the notification information is acquired and the user's location (that is, the time when the notification based on the notification information is performed and the user's location). Respectively. For example, the property information acquisition unit 160 provides notification in the form of a period such as morning, noon, and night based on the time information provided from the time / position information acquisition unit 151 when the notification information is acquired. Information indicating the time when the information is acquired can be acquired as property information. Further, for example, the property information acquisition unit 160 provides information indicating the user's location based on the user's position information when the notification information is acquired, which is provided from the time / position information acquisition unit 151. Information indicating where the notification information is acquired, such as outdoors, indoors, inside the vehicle, outside the vehicle, etc., can be acquired as property information. The information indicating the location of the user may include information on a more detailed location where the user may exist, such as a home or a company. The information importance score calculation unit 172 can determine the importance of the acquired notification information based on information indicating the time when the notification information is acquired and the location of the user included in the property information.

“Past habit” indicates the user's interest, interest, preference, etc., which can be determined based on the user's behavior log stored in the storage unit 130, for example. For example, the property information acquisition unit 160 refers to the user's action log stored in the storage unit 130 and checks the type of information that the user has browsed in the past, thereby obtaining the same type of information as the acquired notification information. On the other hand, information indicating whether the user has shown interest in the past (that is, information indicating the user's interest in the notification information) can be acquired as property information. The information importance score calculation unit 172 can determine the importance of the acquired notification information based on information indicating the user's interest in the notification information included in the property information.

“Alternative means” indicates whether or not the content of the notification information includes information related to the time when the notification information is acquired and the place where the user is located. When the content of the notification information includes information related to the time when the notification information was acquired and the place where the user is, the notification information includes matters that can only be made at that location at that time. Probability is high. It can be said that the “alternative means” is an index indicating the timely importance of the notification information. For example, the property information acquisition unit 160 acquires information indicating the time and place included in the notification information, and the time when the notification information is acquired and the time when the user is close to the place where the user is located and / or Alternatively, by determining whether or not information about a place is included in the notification information, information indicating the presence or absence of an alternative means in the notification information can be acquired as property information of the notification information. The information indicating the time and place included in the notification information is, for example, information on train transfer (for example, the station name of the transfer station, the name of the route to be transferred, the departure time of the train to be transferred, etc.). For example, when the user is on a train and the information about the train transfer as described above is acquired as the notification information, the property information acquisition unit 160 displays the notification time, If it is not a place, it can be determined that the information is meaningless, that is, information without alternative means. The information importance score calculation unit 172 can determine the importance of the acquired notification information based on the information included in the property information indicating the presence / absence of alternative means in the notification information.

“Information freshness” indicates the freshness of the acquired notification information. For example, the property information acquisition unit 160 refers to the time (date) when the notification information is acquired, and analyzes the content of the notification information by using other information sources such as the Web and a knowledge database, Information indicating the freshness of the notification information can be acquired as property information. For example, the property information acquisition unit 160 extracts a word that becomes a keyword included in the notification information, and performs a search on a plurality of sites and databases for the word. If there is a site or data that matches the keyword word, and the date and time when the site or data was updated is far away from the date and time when the notification information was acquired, the freshness of the notification information is considered old. . As described above, the information indicating the freshness of the notification information is information indicating the newness of the content of the notification information, not the date and time when the notification information is acquired. For example, when the date and time when the notification information is acquired is new but the content itself is not new, the freshness of the notification information is regarded as old. The information importance score calculation unit 172 can determine the importance of the acquired notification information based on information indicating the freshness of the notification information included in the property information.

Here, the calculation process of the information importance score by the information importance score calculation unit 172 will be described in more detail with an example of a specific situation. For example, “time” is divided into “morning”, “daytime”, and “night”, “location” is divided into “in-car”, “outdoor”, and “indoor”, and “past habit” is set to “notification information” Divided into “Interested (hereinafter simply interested)” and “Not interested in notification information (hereinafter simply not interested)”, “Alternative means” divided into “Yes” and “None”, and “Information freshness” Let's consider the case where is divided into “new” and “old”. In this embodiment, according to the type of notification information (for example, information about news, information about weather forecast, information about transfer of trains, etc.), for example, these items are set to 0 to 5 respectively as described below. The score up to the point is set. Here, an example of the score of each item that can be set for the information about the weather forecast is shown.

(Times of Day)
Morning: 1 pt.
Daytime: 1 pt.
Night: 1 pt.

(place)
In the car: 3 pt.
Outdoor: 4 pt.
Indoor: 2 pt.

(Past customs)
Not interested: 1 pt.
Interested in: 3pt.

(Alternative means)
None: 5 pt.
Available: 2 pt.

(Freshness of information)
New: 5 pt.
Old: 1 pt.

Note that these scores are merely examples, and specific values of scores set for each item may be arbitrarily set. For example, these scores can be set as appropriate so that an appropriate notification method can be determined based on the past action log of the user. For example, if the frequency of the user confirming information about the weather forecast is higher in the morning time zone than in other time zones from the user's past action log, the “time” “morning” May be set higher than the scores at other times. Alternatively, these scores may be appropriately set by the user so that a notification method desired by the user can be realized. For example, when the user wants to notify the weather forecast information in the morning before other times, the user sets the “morning” score of “time” to a higher value than the scores of other times. do it.

The information importance score can be calculated as the total score of each item when the notification information is acquired. For example, when the user is indoors in the morning and the information about the weather forecast is acquired as the notification information, the information importance score of the information about the weather forecast is: time: morning: 1 pt. Location: Indoor: 2 pt. Past habits: Interested: 3 pt. Alternative: Yes: 2 pt. Freshness of information: New: 5 pt. And a total of 13 points. Therefore, in this example, when information about the weather forecast is acquired as notification information, the information importance score calculation unit 172 calculates the information importance score of the information about the weather forecast as 13 points. .

Thus, in this embodiment, in addition to the time when the notification information is acquired and the location of the user when the notification information is acquired, the information importance score, the past action log of the user, and the notification information Can be calculated based on the freshness of the information, the timely importance of the notification information, and the like. Accordingly, the importance level of the notification information is determined from various viewpoints, and the importance level of the notification information can be reflected more accurately in the calculated information importance score.

(4. Notification method decision process)
As described above, the notification method determination unit 180 can determine the notification method of notification based on the notification information for the user based on the user information and the property information. Specifically, the notification method determination unit 180 determines a notification device and a notification unit as a notification method based on the information importance score and the user status score of the notification information.

Referring to FIG. 2, a detailed procedure of notification device determination processing and notification means determination processing by the notification method determination unit 180 will be described. FIG. 2 is an explanatory diagram for describing notification device determination processing and notification means determination processing by the notification method determination unit 180.

FIG. 2 schematically shows a two-dimensional matrix composed of the user status score and the information importance score, with the user status score on the horizontal axis and the information importance score on the vertical axis. When the notification information is acquired, the user state score and the information importance score are calculated according to the notification information, so that one point on the matrix shown in FIG. 2 corresponds to one notification information. Become.

As shown in FIG. 2, the user state score on the horizontal axis includes each device (in the example shown in FIG. 2, a strap type device, a mobile terminal type device (such as a smartphone or a tablet PC)), a list according to the value. Band type device, necklace type device, earphone type device, glass type device, and HMD device). For example, a strap type device or a portable terminal type device is assigned to an area with a relatively low user status score, and a glass type device or an HMD device is assigned to an area with a relatively high user status score.

Here, for example, the strap type device and the portable terminal type device can notify the user of the notification information by virtue of vibrating itself, by the notification means acting on the tactile sense (that is, the tactile notification means). In addition, the earphone device can notify the user of notification information by voice through notification means that acts on hearing (that is, auditory notification means). In addition, the glass type device and the HMD device can notify the user of the notification information by displaying the information on the display screen, by the notification means that acts visually (that is, the visual notification means). In general, the auditory notification means than the tactile notification means, and the visual notification means than the auditory notification means can draw more attention from the user (that is, the user is noticed). Easy). Therefore, in this embodiment, as the user state score increases, the information can be notified from the device capable of notifying information by the tactile notification means, the device capable of notifying information by the auditory notification means, and the visual notification means. Each device is assigned to the user state score so as to shift to a device that can be notified and a device that gradually increases the ability to attract the user's attention.

In the matrix shown in FIG. 2, for a certain user status score, all devices assigned to an area below the user status score can be determined as notification devices. For example, it is assumed that a certain notification information is acquired, and as a result of calculating the user state score and the information importance score, a value corresponding to the point X shown in FIG. 2 is calculated. In this case, an earphone type device, a necklace type device, a wristband type device, a portable terminal type device, and a strap type device that are assigned to the area below the user state score corresponding to the point X can be selected as the notification device.

Note that the assignment of devices to the user status score can be automatically set by the information notification system 1 according to, for example, the type and number of devices associated with the user. In the present embodiment, the notification method determination unit 180, for example, based on device information acquired by the device information acquisition unit 153, the type and number of devices associated with the user (that is, the user possesses) And a usable notification device can be assigned to the user status score. At this time, for example, the notification method determination unit 180 naturally does not assign a device that is determined not to be possessed by the user from the device information as a notification device. Even if the device is owned by the user, the device is turned off, prohibited from being used as a notification device in individual settings on the device, or when the user logs into the device When a situation such as not being determined is determined based on the device information, the notification method determination unit 180 does not assign these devices as notification devices. Thus, by determining the notification device that can be used based on the device information, it is possible to determine the notification device in accordance with the user's situation.

For example, the notification method determination unit 180 equally divides the range from the lower limit value to the upper limit value of the user status score that can be taken systematically according to the number of devices that the user possesses, and the user possesses each area. Allocate existing devices. For example, when the user possesses a mobile terminal device and an earphone device, the notification method determination unit 180 divides the user state score from the lower limit value to the upper limit value into two equal parts, and the user state score is low A mobile terminal type device is assigned to and an earphone type device is assigned to an area having a high user state score. In this case, when the notification information is acquired and the calculated user state score is equal to or lower than the intermediate value (that is, the lower side of the range between the lower limit value and the upper limit value is divided into two equal parts), the mobile terminal A type device may be selected as the notification device. On the other hand, when the calculated user state score is larger than the intermediate value, both the earphone device and the mobile terminal device are selected as the notification device.

For example, in the information notification system 1, the order as shown in FIG. 2 is given as a default setting as the order of devices with respect to the user status score. However, the order and assignment of the devices may be changed as appropriate by the user. For example, if the order of the “HMD” device is set before the “strap type” device (the side with the lowest user status score), the device with the “HMD” is assigned to the region with the lowest user status score. Therefore, whenever notification information is acquired, it is possible to receive notification from the “HMD” device.

On the other hand, in the information importance score on the vertical axis, notification means (in the example shown in FIG. 2, light (dedicated lamp), vibration, character (only notification), notification sound, character (partial) in the example shown in FIG. 2). , Voice, light (display), characters (all), video / image). For example, a notification means such as “light (dedicated lamp)” or “vibration” is assigned to an area having a relatively low information importance score, and “characters (all ) ”Or“ moving image / image ”.

Here, for example, the notification means such as “light (dedicated lamp)” and “vibration” can notify the user that the notification information has been acquired, but cannot notify the content of the notification information. It can be said that this is a notification means with low ability (small amount of information). On the other hand, the notification means such as “character (all)” or “video / image” is a notification means that directly presents the content of the notification information to the user and has a high transmission capability (a large amount of information). I can say that. In the present embodiment, each notification means is assigned to the information importance score so that the information importance score is gradually shifted to a notification means that can provide a larger amount of information as the information importance score becomes higher.

Note that “light (dedicated lamp)” is a notification means that is provided on the outside of the housing of the device, for example, to turn on or blink a dedicated lamp that indicates that notification information has been acquired. “Vibration” is notification means that vibrates the device itself by driving a vibration element provided inside the device.

“Notification sound” and “sound” are both notification means for outputting sound from a sound output device (for example, a speaker) of the device, but the information amounts of the sound information to be output are different from each other. The “notification sound” is not a notification means for notifying the content of the notification information, but is a notification means for outputting sound such as a buzzer or an alarm. On the other hand, “voice” is a notification means for directly outputting the content of the notification information as voice. Although not shown in FIG. 2, the “voice” may be further subdivided. For example, if the notification information is information on the content that promotes the release of a certain music content, the “voice” is the metadata of the music content (singer name, composer name, songwriter name, etc.) It may be a notification means (for example, referred to as “voice (information)”) that provides the release date or the like as voice information, or a notification means (for example, “voice (music)”) that provides the music itself of the music content. May also be called.) In this case, since it is considered that “voice (music)” can provide more information to the user than “voice (information)”, for example, “voice (music)” on the vertical axis shown in FIG. Can be assigned to an area having a higher information importance score than “voice (information)”.

"Light (display)" is a notification means for lighting or blinking the display screen of the device. “Movie / image” is a notification means for directly displaying the content of the notification information on the display screen of the device. “Light (display)” and “video / image” are executed on a device such as a glass-type device or an HMD device in which the display screen is always located in front of the user's face. It can be a notification means to call out.

“Character (notification only)”, “character (partial)”, and “character (all)” are all notification means for displaying character information on the display screen of the device. Are different from each other. “Character (only notification)” is a notification means that does not display the content of the notification information itself on the display screen and simply displays only the character information indicating that the notification information has been acquired. “Character (part)” is a notification means for displaying only a part of the content of the notification information on the display screen as character information. “Character (all)” is a notification means for displaying all the contents of the notification information on the display screen as character information.

3 to 8 show specific examples of notification means of “character (notification only)”, “character (partial)”, and “character (all)”. FIG. 3 is a diagram illustrating a display example of a “character (only notification)” notification unit in a mobile terminal device (for example, a smartphone). FIG. 4 is a diagram showing a display example of the “character (part)” notification means in the portable terminal device. FIG. 5 is a diagram showing a display example of the “character (all)” notification means in the portable terminal device. FIG. 6 is a diagram showing a display example of the “character (notification only)” notification means in the glass-type device. FIG. 7 is a diagram showing a display example of “character (part)” notification means in the glass-type device. FIG. 8 is a diagram showing a display example of “character (all)” notification means in the glass-type device.

3 to 5, character information is displayed in the display screen 200 of the portable terminal type device. As shown in FIG. 3, “character (only notification)” displays only the character information indicating that the notification information has been acquired, and does not display the content of the notification information. On the other hand, as shown in FIG. 4, “character (part)” displays a part of the content of the notification information in the display screen 200, and as shown in FIG. 5, “character (all)” displays All the contents of the notification information can be displayed in the screen 200.

Similarly, referring to FIG. 6 to FIG. 8, character information is displayed in the display screen 300 of the glass type device. As shown in FIG. 6, “character (only notification)” displays only the character information indicating that the notification information has been acquired, and does not display the content of the notification information. On the other hand, as shown in FIG. 7, “character (part)” displays a part of the content of the notification information in the display screen 300, and as shown in FIG. 8, “character (all)” displays All the contents of the notification information can be displayed in the screen 300.

As for the information importance score, as with the user status score, all notification means assigned to an area below the information importance score with respect to a certain information importance score can be determined as effective notification means. For example, it is assumed that a certain notification information is acquired, and as a result of calculating the user state score and the information importance score, a value corresponding to the point X shown in FIG. 2 is calculated. In this case, “speech”, “character (partial)”, “notification sound”, “character (notification only)”, “vibration” and “ The “light (dedicated lamp)” notification means may be selected as an effective notification means. However, since “character (notification only)”, “character (partial)” and “character (all)” cannot be executed at the same time, a higher-level notification means can be preferentially selected. Also, “notification sound” and “sound”, “light (dedicated lamp)” and “light (display)” are less likely to be executed if the higher-order notification means is executed. The higher-order notification means may be preferentially selected.

Here, the type and number of notification means that can be executed vary depending on the type and number of devices possessed by the user. Therefore, like the user status score, the allocation of the notification means to the information importance score can be automatically set by the information notification system 1 according to, for example, the type and number of devices possessed by the user. For example, the notification method determination unit 180 equally divides between the lower limit value and the upper limit value of the information importance score that can be taken systematically according to the number of notification means that can be executed by the device possessed by the user, Notification means that can be executed by devices owned by the user are allocated to the area. For example, in the information notification system 1, the order shown in FIG. 2 is given as a default setting as the order of the notification means for the information importance score. However, the order and assignment of the notification means may be changed as appropriate by the user, similar to the user status score.

Table 1 below summarizes the relationship between device types and notification means that can be executed by each device. The notification method determination unit 180 refers to a table as shown in Table 1 below, extracts executable notification means according to the device owned by the user, and information importance as illustrated in FIG. The notification means can be assigned to the score.

Note that the relationship between the device types described in Table 1 above and the notification means executable by each device is merely an example, and is not limited to such an example. Actually, the notification means can be appropriately set according to the output device mounted on each device. For example, even if a strap-type device is not equipped with a dedicated lamp for information notification, unlike Table 1 above, the “light (dedicated lamp)” notification means is not provided in the strap-type device. It becomes impossible to execute. Conversely, if the device has a function capable of displaying about one line of characters, regardless of the description in Table 1, the device uses “character (notification only)” as a notification means. It becomes possible to execute.

Thus, in practice, the notification means can be determined according to the notification device, and conversely, the notification device can be determined according to the notification means. In the present embodiment, the notification method determination unit 180 can determine a more appropriate notification device and notification means by comprehensively considering the calculated user information score and information importance score.

Note that the notification method determination unit 180 may determine the time for executing the notification unit according to the information importance score when determining the notification unit. For example, even if the “voice” is the same, if the time during which the voice information is output is long, a larger amount of information is given to the user than when the time during which the voice information is output is short. Will be provided. In this way, even if the notification means is the same, the amount of information provided to the user can differ depending on the time for executing the notification means. For example, the notification method determination unit 180 may determine the notification unit so that the higher the information importance score, the longer the time for executing the notification unit.

Here, in practice, the executable notification means may be limited depending on the type and content of the notification information. For example, when the notification information does not include image information, even if the information importance score is high, it cannot be said that “moving image / image” is appropriate as a notification means. The notification method determination unit 180 can determine the type of notification means assigned to the vertical axis shown in FIG. 2 according to the type and content of notification information. Similarly, the notification method determination unit 180 can determine the type of notification device assigned to the horizontal axis shown in FIG. 2 according to the type and content of notification information. Thereby, for example, even when the same user state score and information importance score are calculated, a more appropriate notification device and notification means are selected according to the type and content of the notification information. . For example, even when the same user status score and information importance score are calculated, when the notification information includes voice information, “voice” is preferably selected as the notification means, and the “voice” is selected. A device that can be executed as a notification means can be suitably selected as a notification device. When the notification information includes image information, “moving image / image” is preferably selected as the notification unit, and a device that can be executed using the “moving image / image” as the notification unit is preferably selected as the notification device. As described above, in the present embodiment, the notification information can be notified to the user by a more appropriate notification method that considers the type and content of the notification information.

Note that the relationship between the user status score and the notification device and the relationship between the information importance score and the notification means as shown in FIG. 2 can be expressed as a table as shown in FIG. . The notification method determination unit 180 may determine the notification method using a table as shown in FIG. FIG. 9 is a diagram illustrating an example of a table used in notification method determination processing by the notification method determination unit 180.

In FIG. 9, similarly to FIG. 2, the horizontal axis represents the user state score, the vertical axis represents the information importance score, and a two-dimensional matrix composed of the user state score and the information importance score is schematically shown. ing. In FIG. 9, as an example, the user status score and the information importance score are based on each item described in the above (2. User status score calculation process) and (3. Information importance score calculation process). The table in the case of being calculated is shown. In other words, the user status score on the horizontal axis is calculated as the total value of the scores in each item of “time”, “location”, “user status”, and “device status”, the minimum value is zero, and the maximum value is 20. Also, the information importance score on the vertical axis is calculated as the total value of the scores in each item of “time”, “place”, “past habit”, “freshness of information” and “alternative means”, and the minimum value thereof Is zero and the maximum is 25.

For example, in the table shown in FIG. 9, a matrix composed of the user status score and the information importance score is divided into a plurality of areas 400, and a notification device and a notification means are assigned to each area 400. As in the case shown in FIG. 2, the notification device is assigned to each area 400 by assigning a device owned by the user to the user status score. As in the case shown in FIG. 2, the notification means can be assigned to each area 400 by assigning the notification means that can be executed by the device owned by the user to the information importance score. For the sake of explanation, in FIG. 9, different reference numerals 400 a to 400 f are given to the characteristic region 400 in the region 400.

For example, it is assumed that the calculated user status score and information importance score are both low, and a score belonging to the area 400a shown in FIG. 9 is calculated. In this case, for example, only one device among a plurality of devices possessed by the user is selected as a notification device, and “character (notification only)” which is a notification means with a relatively small amount of information is selected. It becomes. This is because when both the user status score and the information importance score are low, the necessity of notifying the user that the notification information has been acquired is low, and the importance of the content of the notification information is considered low.

Also, for example, it is assumed that the calculated user status score is high but the information importance score is low, and a score belonging to the area 400b shown in FIG. 9 is calculated. In this case, for example, all of the plurality of devices possessed by the user are selected as notification devices, and “character (notification only)” which is a notification means with a relatively small amount of information is selected. If the user status score is high but the information importance score is low, the necessity of notifying the user that the notification information has been acquired is high, but the importance of the content of the notification information is considered low It is.

Also, for example, it is assumed that the calculated user status score is low, but the information importance score is high, and a score belonging to the area 400c shown in FIG. 9 is calculated. In this case, for example, only one device among a plurality of devices possessed by the user is selected as a notification device, and “character (all)” which is a notification means having a relatively large amount of information is selected. Become. If the user status score is low but the information importance score is high, the necessity of notifying the user that the notification information has been acquired is low, but the importance of the content of the notification information is considered high It is.

Also, for example, it is assumed that the calculated user status score is high, but the information importance score is medium, and a score belonging to the area 400d shown in FIG. 9 is calculated. In this case, for example, all of a plurality of devices possessed by the user are selected as notification devices, and “character (part)”, which is a notification means with a medium amount of information, as well as “voice” or “video / "Image" will be selected. If the user status score is high but the information importance score is medium, the necessity of notifying the user that the notification information has been acquired is high, but the importance of the content of the notification information is medium This is because it is considered.

Also, for example, it is assumed that the calculated user status score is medium, but the information importance score is high, and a score belonging to the area 400e shown in FIG. 9 is calculated. In this case, for example, a part of a plurality of devices possessed by the user is selected as a notification device, and “character (all)” and “speech”, which are notification means having a relatively large amount of information, or “Movie / image” is selected. When the calculated user status score and information importance score belong to the area 400e, the number of notification devices to be selected increases compared to the case where the calculated user status score and information importance score belong to the area 400c. Therefore, even if the information importance score is about the same as that belonging to the area 400c, more types of notification means can be selected, and notification information can be notified to the user with a larger amount of information.

Also, for example, assume that the calculated user status score and information importance score are both high, and a score belonging to the area 400f shown in FIG. 9 is calculated. In this case, for example, all of a plurality of devices possessed by the user are selected as notification devices, and “character (all)”, “sound”, and “moving image / image”, which are notification means having a relatively large amount of information, are displayed. Will be selected. When the calculated user status score and information importance score belong to the area 400f, the number of notification devices to be selected is increased compared to the case where the calculated user status score and information importance score belong to the areas 400c and 400e, so the number of executable notification means is also increased. To do. Therefore, even if the information importance score is about the same as that belonging to the areas 400c and 400e, more types of notification means are selected, and the notification information can be notified to the user with a larger amount of information.

As described above, the notification method determination unit 180 can determine the notification method according to the user status score and the information importance score using the table as shown in FIG. Here, in the present embodiment, the notification method determination unit 180, when the user situation estimated based on the user information is a specific situation, for a predetermined notification method set in advance, for example, to the user The notification method may be determined so that the amount of information notified is reduced. For example, if the user is wearing a glass-type device or an HMD device, and it is estimated from the user information that the user is driving a car, even if the information importance score is high, Visual notification means (for example, “moving image / image” or “character (all)”) should not be executed. Also, many notification devices should not be selected even if the user status score is high. If notifications from multiple devices are performed at the same time while driving a car or visual notification means are executed, it will be difficult for the user to concentrate on driving the car and there is a risk of hindering safe driving. Because there is. Therefore, for example, when it is estimated that the user is driving a car, the notification method determination unit 180 appropriately corrects the user state score and the information importance score, thereby reducing a relatively small number of notification devices. Or other notification means that are not visual notification means can be selected.

In the present embodiment, for example, the storage unit 130 stores a table indicating the relationship between a user situation and a notification method suitable for the user situation. The notification method determination unit 180 can determine a notification method suitable for a user situation by referring to the table when the user situation is a specific situation.

The notification method determination unit 180 appropriately corrects the user status score and the information importance score so that the preset notification method is selected, so that the preset notification described above is performed. A process for determining a method may be realized. In this case, for example, the storage unit 130 includes a table indicating the relationship between the user status, the notification method suitable for the user status, and the user status score and information importance score corresponding to the notification method. The notification method determination unit 180 stores the user state score so that a notification method suitable for the user situation is selected by referring to the table when the user situation is a specific situation. In addition, the information importance score can be corrected as appropriate.

The function of the notification method determination unit 180 has been described above. As described above, in the notification method determination unit 180, the notification device is determined according to the user information, and the notification means is determined according to the property information of the notification information. Specifically, the notification device is determined according to the user status score, and the notification means is determined according to the information importance score. For example, the notification method determination unit 180 can select more types of notification devices such that the higher the user state score, the more attention can be given to the user. For example, the notification method determination unit 180 can select a notification unit that can provide a larger amount of information to the user as the information importance score increases. Therefore, a more appropriate notification device and notification means can be determined according to the user status and the content of the notification information.

Further, the notification method determination unit 180 may determine the notification device and the notification unit in consideration of the type and content of the notification information. Thereby, for example, even when the same user state score and information importance score are calculated, a more appropriate notification method is determined according to the type and content of the notification information.

Further, when the user situation estimated based on the user information is a specific situation, the notification method determination unit 180 corrects the user state score and the information importance score, and selects a predetermined notification method. Also good. Accordingly, selection of a notification device and a notification unit that cause danger to the user can be avoided, and notification information can be notified to the user by a more appropriate notification method according to the user's situation.

(5. Specific example)
Taking a specific situation as an example, a specific process performed in the information notification system 1 when notification information is notified to the user will be described. Here, as an example, the user status score and the information importance score are calculated based on the items described in the above (2. User status score calculation processing) and (3. Information importance score calculation processing). The case where it will be described. That is, the user state score is calculated as a total value of scores in each item of “time”, “location”, “user status”, and “device state”, and the minimum value is zero and the maximum value is 20. . The information importance score is calculated as the total score of each item of “time”, “place”, “past habit”, “information freshness”, and “alternative means”, and the minimum value is zero, The maximum value is 25.

(5-1. When the user is on the train at night)
The user information acquisition unit 152 provides sensor information provided from sensors of the sensor unit 110 and other devices 20, time information and position information provided from the time / position information acquisition unit 151, and provided from the device information acquisition unit 153. User information is obtained based on the device information. The user information may include, for example, information indicating that the user is moving on the last train and that the user is likely to sleep as information indicating the user's situation. As described above, the user information acquisition unit 152 can determine the user's situation based on sensor information, time information, position information, and / or device information obtained from a plurality of devices possessed by the user. In this case, the user state score is as follows, for example.

(User status score)
Time: Night: 3
Location: Inside the car: 4
User situation: moving + sleeping: 5
Device status: Standby: 3
Total: 15

At this time, it is assumed that information about the current location of the user in the route and information about the next station are acquired by the information processing apparatus 10 as notification information. The notification information can be provided by, for example, a service that provides position information of the user on the route. In this case, the information importance score of the notification information is, for example, as follows.

(Information importance score)
Time: Night: 1
Location: Inside the car: 3
Alternative: None: 5
Past customs: interested: 3
Freshness of information: New: 5
Total: 17

The notification method determination unit 180 determines a notification device and a notification unit based on the user status score and the information importance score. In the case of the specific example, the user state score has a relatively high value. Accordingly, a relatively large number of devices (or all devices) among a plurality of devices possessed by the user can be selected as the notification device. The information importance score is also relatively high. Therefore, a plurality of notification means by a plurality of devices possessed by the user can be selected.

For example, the user has a glass type device, a necklace type device, a wristband type device and a portable terminal type device, and all these devices are selected as the notification device, and “light (display)”, “character” is selected as the notification means. It is assumed that “all” and “vibration” are selected. In this case, the entire screen of the glass-type device blinks, and information on the next station can be displayed as character information on the display screen. In addition, necklace type devices, wristband type devices and portable terminal type devices can be vibrated. These notification operations may be terminated when the user performs an operation input indicating that the notification information has been confirmed with respect to any device.

(5-2. When the user is at home in the morning)
Similar to the above (5-1. When the user is on a train at night), the user information acquisition unit 152 is configured to obtain sensor information, time information, position information, and / or information obtained from a plurality of devices owned by the user. Alternatively, based on the device information, for example, information indicating that the user is highly likely to be at home in the morning can be acquired as information indicating the user's situation. In this case, the user state score is as follows, for example.

(User status score)
Time: Morning: 2
Location: Indoor: 1
User situation: Stopping + Waking up: 3
Device status: Standby: 3
Total: 9

At this time, it is assumed that predetermined information (for example, information about weather forecasts, train delay information, etc.) confirmed by the user every morning is acquired as notification information by the information processing apparatus 10. The information can be provided by, for example, a service that provides information on weather forecasts and traffic conditions. In this case, the information importance score of the notification information is, for example, as follows.

(Information importance score)
Time: Morning: 1
Location: Indoor: 2
Alternative: Yes: 2
Past customs: interested: 3
Freshness of information: New: 5
Total: 13

The notification method determination unit 180 determines a notification device and a notification unit based on the user status score and the information importance score. In the case of the specific example, the user state score has a medium value. Accordingly, some but not all of the devices owned by the user may be selected as the notification device. Also, the information importance score has a medium value. Therefore, for example, a notification means that can provide a smaller amount of information than (5-1. When a user is on a train at night) can be selected.

For example, when the user has a glass-type device, a necklace-type device, a wristband-type device, and a portable terminal-type device, as in (5-1. When the user is on a train at night) Even so, only some of these devices can be selected as the notification device, and “light (display)” and “vibration” can be selected as the notification means. Thus, in this specific example, both the user state score and the information importance score are low compared to the above (5-1. When the user is on the train at night), so the notification information to the user The content of is not notified, but only that the notification information has been acquired is notified.

(5-3. When the user is working at work in the daytime)
Similar to the above (5-1. When the user is on a train at night), the user information acquisition unit 152 is configured to obtain sensor information, time information, position information, and / or information obtained from a plurality of devices owned by the user. Alternatively, based on the device information, for example, information indicating that the user is likely to work in the office at noon can be acquired as information indicating the user's situation. In this case, the user state score is as follows, for example.

(User status score)
Time: Noon: 1
Location: Indoor: 1
User situation: Stopping + Waking up: 3
Device status: Charging: 2
Total: 7

At this time, it is assumed that the information processing apparatus 10 acquires the same information as the information confirmed by the user in the morning as the notification information. In this case, the freshness of the information is considered old. The information importance score of the notification information is, for example, as follows.

(Information importance score)
Time: Noon: 1
Location: Indoor: 2
Alternative: Yes: 2
Past customs: interested: 3
Information freshness: old: 1
Total: 9

The notification method determination unit 180 determines a notification device and a notification unit based on the user status score and the information importance score. In the case of the specific example, the user state score has a relatively low value. Therefore, for example, only one device among a plurality of devices possessed by the user can be selected as the notification device. The information importance score is also low. Accordingly, a notification means that can provide a relatively small amount of information can be selected from notification means that can be executed by the selected notification device.

For example, even if the user has a glass type device, a necklace type device, a wristband type device, and a portable terminal type device, only one of these as a notification device (for example, a portable terminal type device) Can be selected as the notification means, such as “character (only notification)” or “vibration”, which has a small amount of information that can be provided. As described above, in this specific example, both the user state score and the information importance score are low, and therefore a notification method for performing minimum notification to the user can be selected.

(5-4. When the user is out during the day)
Similar to the above (5-1. When the user is on a train at night), the user information acquisition unit 152 is configured to obtain sensor information, time information, position information, and / or information obtained from a plurality of devices owned by the user. Alternatively, based on the device information, for example, information indicating that the user is likely to go out at noon can be acquired as information indicating the user's situation. In this case, the user state score is as follows, for example.

(User status score)
Time: Noon: 1
Location: Outdoor: 4
User situation: Moving + Waking up: 4
Device status: Standby: 3
Total: 12

At this time, it is assumed that information indicating that the product searched by the user in the past is sold at a store near the location where the user is present is acquired as the notification information by the information processing apparatus 10. The information can be provided, for example, by a service that recommends products that the user seems to be interested in, such as a so-called recommendation service at a mail order site. The information importance score of the notification information is, for example, as follows.

(Information importance score)
Time: Noon: 1
Location: Outdoor: 4
Alternative: Yes: 2
Past customs: interested: 3
Freshness of information: New: 5
Total: 15

The notification method determination unit 180 determines a notification device and a notification unit based on the user status score and the information importance score. In the case of the specific example, the user state score has a relatively high value. Accordingly, a relatively large number of devices (or all devices) among a plurality of devices possessed by the user can be selected as the notification device. Further, the information importance score has a medium value. Therefore, a notification means that can provide a medium amount of information such as “voice” can be selected.

For example, if the product related to the notification information is a product that can be obtained only at the store notified by the notification information, the item of “alternative means” in the information importance score is “none”, and the information The importance score is even higher. Therefore, the types of notification means to be selected increase, and notification means that can provide a larger amount of information to the user, such as “character (all)” and “moving image / image”, can be selected. Therefore, more detailed contents of the notification information are notified to the user.

(5-5. When the user is driving a car during the day)
Similar to the above (5-1. When the user is on a train at night), the user information acquisition unit 152 is configured to obtain sensor information, time information, position information, and / or information obtained from a plurality of devices owned by the user. Alternatively, based on the device information, for example, information indicating that the user is likely to drive a car at noon can be acquired as information indicating the user's situation. In this case, the user state score is as follows, for example.

(User status score)
Time: Noon: 1
Location: Inside the car: 4
User situation: Moving + Waking up: 4
Device status: Standby: 3
Total: 12

At this time, similar to the above (5-4. When the user is out in the daytime), the product searched by the user in the past is near the place where the current user is, as the notification information by the information processing apparatus 10. Suppose that information indicating that it is sold at the stores of is acquired. The information importance score of the notification information is, for example, as follows.

(Information importance score)
Time: Noon: 1
Location: Inside the car: 3
Alternative: Yes: 2
Past customs: interested: 3
Freshness of information: New: 5
Total: 14

The notification method determination unit 180 determines a notification device and a notification unit based on the user status score and the information importance score. In the case of this specific example, the user state score takes a relatively high value and the information importance score takes a medium value, as in the above (5-4. When the user is out during the day). ing. Therefore, a relatively large number of devices (or all devices) among a plurality of devices possessed by the user can be selected as the notification device. Also, a notification means that can provide a medium amount of information can be selected.

However, as described above (4. About notification method determination processing), in the present embodiment, the notification method determination unit 180 is configured when the user situation estimated based on the user information is a specific situation. Can correct the user status score and the information importance score and select a predetermined notification method. For example, as in this specific example, when it is estimated that the user is driving a car, the notification method determination unit 180 does not select too many devices as notification devices, and visual notification means Is set not to select. Therefore, in this specific example, the user status score and the information importance score are appropriately corrected, and the minimum notification device and notification means that do not hinder the user's driving can be selected.

(6. Information processing method)
With reference to FIG. 10, a processing procedure of an information processing method that can be executed in the information notification system 1 according to the present embodiment described above will be described. FIG. 10 is a flowchart illustrating an example of a processing procedure of the information processing method according to the present embodiment.

Referring to FIG. 10, in the information processing method according to the present embodiment, first, user information and property information of the notification information are acquired at the timing when the notification information is acquired (step S101). Here, the notification information is, for example, from the external server related to the service that provides the user with various information such as information about the weather forecast and train operation information, to the information processing apparatus 10 as new arrival information in the service. Delivered. Further, the user information is based on time information indicating the current time, position information indicating the current device position (that is, user position), and / or device information, for example, as shown in FIG. Can be obtained by Further, the property information is obtained based on the time information indicating the current time, the position information indicating the current device position (that is, the position of the user), and / or the content of the notification information, for example, as shown in FIG. It can be acquired by the unit 160. Here, the time information and the position information can be acquired by, for example, the time / position information acquisition unit 151 illustrated in FIG. The device information can be acquired by, for example, the device information acquisition unit 153 illustrated in FIG. Moreover, user information can be acquired by the user information acquisition part 152 shown in FIG. 1, for example. Also, the property information can be acquired by, for example, the property information acquisition unit 160 shown in FIG.

When the notification information is acquired, it is next determined whether or not the notification information is information to be notified to the user according to a predetermined standard (step S103). The process shown in step S103 corresponds to the process executed by the notification method determination unit 180 shown in FIG. 1 described above, for example. In the process shown in step S103, for example, when notification information having the same content as the notification information already notified to the user is obtained, or when notification information of the same type is acquired in the past, the user receives the notification information. It can be determined that notification information that is considered to be less necessary to be notified to the user, such as when it is discarded without confirming the contents, is not information to be notified to the user.

If it is determined that the notification information acquired in step S103 is not information to be notified to the user, the process returns to step S101 and waits until the next notification information is acquired. On the other hand, if it is determined that the notification information acquired in step S103 is information to be notified to the user, the process proceeds to step S105.

In step S105, based on the user information acquired in step S101, a user state score representing the necessity of the notification information for the user when the notification information is acquired is calculated. The process shown in step S105 corresponds to, for example, the process executed by the user state score calculation unit 171 shown in FIG. In the process shown in step S105, for example, the user status score is calculated based on items such as “time”, “location”, “user status”, and “device status”.

Next, based on the property information acquired in step S101, an information importance score indicating the importance of the notification information is calculated (step S107). The process shown in step S107 corresponds to the process executed by, for example, the information importance score calculation unit 172 shown in FIG. In the process shown in step S107, for example, an information importance score is calculated based on items such as “time”, “place”, “past habit”, “freshness of information”, and “alternative means”.

Note that the processes shown in step S105 and step S107 may not be executed in the order shown, and may be executed in the reverse order or in parallel.

Next, it is determined whether or not the user situation estimated based on the user information is a specific situation (step S109). The process shown in step S109 corresponds to the process executed by, for example, the notification method determination unit 180 shown in FIG. In the process shown in step S109, based on the information indicating the user's situation included in the user information, it is determined whether or not the user's situation is a specific situation such as driving a car.

If it is determined in step S109 that the user's situation is not a specific situation, the process proceeds to step S111, and a notification information notification method is determined based on the calculated user state score and information importance score. The process shown in step S111 corresponds to the process executed by the notification method determination unit 180 shown in FIG. In the processing shown in step S111, for example, the notification device is determined according to the user status score and the notification means is determined according to the information importance score by the method described in the above (4. Notification method determination processing). The

On the other hand, if it is determined in step S109 that the user situation is a specific situation, the process proceeds to step S113, and the user state score and the information importance score are corrected according to the user situation. The process shown in step S113 corresponds to the process executed by, for example, the notification method determination unit 180 shown in FIG. When the user status score and the information importance score are corrected in step S113, the process proceeds to step S111, and an information notification method is determined based on the corrected user status score and information importance score. As a result, for example, a user who is driving a car is not notified by a plurality of notification means including a visual notification means by a plurality of devices, which may cause danger to the user. It is avoided that a method is selected.

In the present embodiment, instead of correcting the user status score and the information importance score in step S113, a notification method according to the estimated user status regardless of the values of the user status score and the information importance score. May be determined directly. For example, a table indicating a relationship between a user situation and a notification method suitable for the user situation is prepared in advance, and a notification method suitable for the user situation estimated from the user information based on the table May be appropriately determined.

The information processing method according to the present embodiment has been described above.
