(Embodiment)
[1. Provision processing)
First, an example of a providing process according to the embodiment will be described with reference to FIG. FIG. 1 is a diagram illustrating an example of a providing process according to the embodiment. In the example illustrated in FIG. 1, the providing device 100 provides a navigation service (hereinafter also referred to as “navigation service”) to the terminal device 10 in which an application related to navigation is installed. Below, the case where the navigation application A which is an application regarding car navigation is installed in the terminal device 10 will be described as an example. Hereinafter, the navigation may be simply referred to as “navigation”. In the following, the navigation application A, which is a car navigation application, is shown as an example. However, the navigation service is not limited to car navigation, and may be various services such as walking navigation and bicycle navigation.

  As shown in FIG. 1, the providing system 1 includes a terminal device 10 and a providing device 100. The terminal device 10 and the providing device 100 are connected to be communicable by wire or wireless via a predetermined communication network (not shown). In addition, the providing system 1 illustrated in FIG. 1 may include a plurality of terminal devices 10 and a plurality of providing devices 100.

  The providing device 100 is an information processing device that provides a navigation service to a user who uses the terminal device 10 in which the navigation application A is installed. The providing apparatus 100 provides a navigation service according to navigation information that is information related to navigation changed based on log information acquired from the terminal apparatus 10 used by a large number of users (for example, one million users). .

  The terminal device 10 is an information processing device used by a user. The terminal device 10 is realized by, for example, a smartphone, a tablet terminal, a notebook PC (Personal Computer), a desktop PC, a mobile phone, a PDA (Personal Digital Assistant), or the like. FIG. 1 shows a case where the terminal device 10 is a smartphone. The terminal device 10 may be any device such as a wearable device as long as it can provide a navigation service. Further, for example, the terminal device 10 may be any device such as a dedicated navigation terminal such as a car navigation device or various devices having a car navigation function such as an automatic driving car as long as it can provide a navigation service. For example, the terminal device 10 may be a smartphone in which the navigation application A is installed. Hereinafter, the terminal device 10 may be referred to as a user. That is, hereinafter, the user can be read as the terminal device 10. For example, in the example of FIG. 1, when it is described as a user identified by the user ID “U1” (hereinafter sometimes referred to as “user U1”), it can be read as the terminal device 10 used by the user U1.

  In the example illustrated in FIG. 1, the terminal device 10 is changed to the terminal devices 10-1 to 10-1 according to the setting of the navigation application A of the terminal device 10 used by the user U <b> 1 (hereinafter also referred to as “navigation parameter”). This will be described as 10-3. The terminal devices 10-1 to 10-3 are the same terminal device 10. In the example illustrated in FIG. 1, the terminal device 10 used by the user identified by the user ID “U2” (hereinafter sometimes referred to as “user U2”) is identified as the terminal device 10 used by the user U1. Therefore, it may be described as a terminal device 10-20. In the following description, the terminal devices 10-1 to 10-3 and 10-20 are referred to as the terminal device 10 when they are not particularly distinguished. For example, when the terminal devices 10 used by a plurality of users are collectively referred to as the terminal device 10.

  The terminal device 10 collects information regarding the terminal device 10. Hereinafter, various types of information collected by the terminal device 10 may be referred to as “log information”. The terminal device 10 transmits the collected log information to the providing device 100. For example, the terminal device 10 collects sensor information detected by various sensor units 13 (see FIG. 6) described later as log information. For example, the terminal device 10 logs various information such as voice information, position information, acceleration information, vibration information, temperature information, atmospheric pressure information, humidity information, and illuminance information detected by each sensor unit 13. Collect as information. The log information is not limited to the sensor information described above, and may include various information such as attribute information of a user who uses the terminal device 10.

  For example, the navigation application A provides a navigation service that guides a vehicle on which a user who uses the terminal device 10 in which the navigation application A is installed to the destination. For example, when the terminal device 10 in which the navigation application A is installed receives an input of a destination from the user, the terminal device 10 provides a navigation service based on map information, road information, and information related to navigation for guiding the user to the destination. . Hereinafter, such map information, road information, information on navigation, and the like may be referred to as “navigation information”.

  For example, the navigation information includes a route to a destination where the vehicle can be used, information on expressways included in the route, traffic jam information on the route, facilities serving as a guide for guidance, information on a map displayed on the screen, guidance Data such as images such as voices and maps that are sometimes output may be included. Further, the terminal device 10 in which the navigation application A is installed receives navigation information from the providing device 100.

  In FIG. 1, a case where the terminal device 10 in which the navigation application A is installed provides a navigation service based on navigation information will be described as an example. Specifically, in the example of FIG. 1, when the terminal device 10 in which the navigation application A is installed guides (navigates) the car C11 on which the user U1 has boarded from the point PT1 to the point PT2 in response to an input from the user U1. Indicates. Map information MP11 in FIG. 1 schematically shows the position of the automobile C11 or the like. Further, in the example of FIG. 1, it is assumed that the terminal device 10 has collected attribute information and the like related to the user U1 and has already stored the user information storage unit 143 (see FIG. 8).

  First, the terminal device 10-1 starts the navigation application A (step S11). For example, the terminal device 10-1 activates the navigation application A in response to an operation by the user U1. Further, as shown in the terminal device 10-1, the navigation application A has various settings ST1 to ST6 and the like. For example, the states of the settings ST1 to ST6 shown in the terminal device 10-1 indicate the initial setting of the navigation application A. In the example of FIG. 1, the terminal device 10-1 and 10-2 show an application setting screen to indicate that the application setting is automatically changed and set. The automatic setting may be performed while the background, that is, the setting screen is not displayed.

  For example, the setting ST1 of the navigation application A is a setting regarding whether or not the traveling direction is to be upward, and is a setting relating to the display of the navigation. In the example of FIG. 1, in the initial setting of the navigation application A, the setting ST <b> 1 is set to “off” and is set so as not to raise the traveling direction. Further, for example, the setting ST2 of the navigation application A is a setting regarding whether to accept a map rotation operation, for example, an operation for changing the direction of the map, and is a setting related to the display of the navigation. In the example of FIG. 1, in the initial setting of the navigation application A, the setting ST <b> 2 is set to “on” and is set to accept a map rotation operation. Further, for example, the setting ST3 of the navigation application A is a setting related to the design of the map and a setting related to the display of the navigation. In the example of FIG. 1, in the initial setting of the navigation application A, the setting ST3 is set to “daytime” and is set so that a map or the like is displayed in the daytime mode.

  Further, for example, the setting ST4 of the navigation application A is a setting regarding whether or not to enlarge a character, and is a setting relating to the display of the navigation. In the example of FIG. 1, in the initial setting of the navigation application A, the setting ST4 is set to “off” and is set not to enlarge the character. Further, for example, the setting ST5 of the navigation application A is a setting relating to the traffic speed. In the example of FIG. 1, in the initial setting of the navigation application A, the setting ST5 is set to “40 km / h” and is set to perform navigation corresponding to traveling at a speed of 40 km / h. Further, for example, the setting ST6 of the navigation application A is a setting of the navigation volume, and is a setting related to the volume of the sound output from the navigation application A. Further, in the example of FIG. 1, in the initial setting of the navigation application A, the setting ST6 is set to “50%” at the substantially center, and is set to the standard audio output level.

  As described above, since the navigation application A has various settings including the settings ST1 to ST6, it is troublesome for the user U1 to set one by one. Are automatically set (step S12). For example, the terminal device 10 automatically sets the navigation application A based on the context of the user U1. For example, the terminal device 10 automatically sets the navigation application A based on the context of the user U1 estimated from log information including attribute information indicating that the user U1 is in his 60s and is a driving beginner.

  Note that the context here means the situation of the user or the terminal device 10 and the environment (background) of the user or the terminal device 10. For example, the context is information corresponding to a situation where the terminal device 10 is used by a user or a state where a user who owns the terminal device 10 is placed. The context includes the content of the content provided to the user, the content of the user's utterance, the user's attributes, the user's current location, the current time, the physical environment in which the user is placed, the social environment in which the user is placed, the user It may be estimated based on various information such as the exercise state of the user and the emotion of the user.

  As shown in the context information storage unit 142 (see FIG. 7), the context is indicated by an abstract symbol such as the context CN11 or the context CN12, but each context is information indicating a specific situation of the user. May be. For example, the context CN11 may be a context corresponding to a situation where “the user is young and the driving level is high (experienced)”. For example, the context CN12 may be a context corresponding to a situation where “the user is old and the driving level is low (beginner)”. For example, in the example of FIG. 1, the terminal device 10 estimates that the context of the user U1 is the context CN12 corresponding to the situation “the user is old and the driving level is low (beginner)”. And the terminal device 10 changes the provision aspect of a navigation based on the context of the user U1 estimated based on log information. For example, the terminal device 10 changes the output mode of the navigation by automatically setting the navigation application A based on the context of the user U1.

  The navigation parameters automatically set by the terminal device 10 are not limited to the above settings ST1 to ST6, and may be various parameters. For example, the navigation parameters automatically set by the terminal device 10 may be various parameters such as the distance to the guidance point and the priority of speech. In addition, as described above, the terminal device 10 has a guide point for people who are not good at driving such as a user U1 in their 60s or who are not good at driving (such as beginners and elderly people). May be output earlier or more.

  Whether the user is a beginner or an expert (driving) with respect to driving may be input by the user or may be estimated (determined) from other user attributes. In addition, whether the user is a beginner or an experienced user may be estimated (determined) based on the collected log information. For example, the providing apparatus 100 may determine whether the user is a beginner or veteran of driving based on the collected acceleration information. For example, the providing apparatus 100 may estimate the user's driving level based on the collected acceleration information, and determine whether the user is a beginner or an experienced driver. For example, in a case where acceleration information that repeatedly starts and stops suddenly with respect to a certain user is collected, the providing apparatus 100 may estimate that the user's driving level is a beginner and determine that the user is a beginner with respect to driving. .

  Note that the automatic setting described above is an example, and the terminal device 10 may automatically set the navigation parameters using various information as appropriate. For example, the terminal device 10 may reflect setting information of a user having an attribute similar to the user who uses the terminal device 10. In this case, the terminal device 10 may acquire setting information (parameter information) of a user having an attribute similar to the user who uses the terminal device 10 from the providing device 100, and may reflect the acquired setting information. For example, the terminal device 10 transmits attribute information similar to a user who uses the terminal device 10 from the providing device 100 to the providing device 100 by transmitting to the providing device 100 attribute information and context information of the user who uses the terminal device 10. The setting information of the user may be acquired and the acquired setting information may be reflected.

  In the example of FIG. 1, the terminal device 10-2 automatically sets (changes) various settings ST1 to ST6 of the navigation application A. For example, the terminal device 10 changes the setting ST1 from “off” to “on”. Further, for example, the terminal device 10 changes the setting ST2 from “ON” to “OFF”. Thereby, in the terminal device 10 in which the navigation application A is activated, the display is performed so that the traveling direction is upward, and thus the display is suitable for the user U1 who is a beginner. In the example of FIG. 1, it is assumed that the time at the time of step S12 is 20:00. Therefore, for example, the terminal device 10 changes the setting ST3 from “daytime” to “night”. Thereby, in the terminal device 10 in which the navigation application A is activated, the display is adapted to the environment around the user U1.

  Further, for example, the terminal device 10 changes the setting ST4 from “off” to “on”. Thereby, in the terminal device 10 in which the navigation application A is activated, characters are displayed in a large size, so that the display is suitable for the user U1 who is in his 60s (elderly). Further, for example, the terminal device 10 changes the setting ST5 from “40 km / h” to “25 km / h”. Thereby, in the terminal device 10 in which the navigation application A is activated, navigation corresponding to the speed slightly decelerated than usual is provided, so that the navigation is suitable for the user U1 who is a beginner and in his 60s (elderly). For example, the terminal device 10 changes the setting ST6 from “50%” to “100%”. Thereby, since the navigation sound is greatly output in the terminal device 10 in which the navigation application A is activated, the sound is suitable for the user U1 who is in his 60s (elderly).

  Note that the user U1 may change manually. Moreover, the terminal device 10 may change the setting according to the change of the context of the user U1 while providing the navigation service. For example, when the user U1 is on the car C11 and is driving alone, the terminal device 10 estimates that the context corresponds to the situation “the user is driving alone” and the navigation application A You may make it restrict | limit operation. The context of the user U1 may be estimated periodically (for example, every 5 minutes) or when the collected log information satisfies a predetermined condition.

  Then, the user U1 drives the automobile C11 and starts moving from the point PT1 to the point PT2. In response to this, the terminal device 10 in which the navigation application A is installed starts guidance (navigation) from the point PT1 to the point PT2. Then, the terminal device 10 in which the navigation application A is installed collects log information related to the user U1 during navigation from the point PT1 to the point PT2. This point will be described below.

  First, in the example illustrated in FIG. 1, the terminal device 10 detects ambient sounds and performs various processes according to the detected sounds. For example, the terminal device 10 processes a user's utterance. For example, the terminal device 10 may have a function related to voice recognition. The terminal device 10 may be able to acquire information from a voice recognition server that provides a voice recognition service. In this case, the providing system 1 may include a voice recognition server. The providing apparatus 100 may have a voice recognition function. In the example of FIG. 1, in order to simplify the description, it is assumed that the terminal device 10 recognizes the user's utterance by appropriately using various conventional techniques.

  Here, when the user U1 who is driving the automobile C11 passes near the restaurant A, which is a POI (Point of Interest) denoted by reference numeral FC1 in FIG. 1, the utterance PA11 “Restaurant A has closed” PA11 I do. Thereby, the terminal device 10 collects information related to the utterance PA11 by the user U1 that “Restaurant A has closed” (step S13). For example, the terminal device 10 collects, as log information, voice information related to the utterance PA11 by the user U1 that “Restaurant A has closed”. For example, the terminal device 10 may collect the log information by associating the position information of the user U1 at the time when the utterance PA11 is performed with the audio information regarding the utterance PA11. The terminal device 10 may transmit the voice information of the utterance PA11 to the voice recognition server, acquire the character information of the utterance PA11 from the voice recognition server, and collect the acquired character information as log information. Further, in the example of FIG. 1, it is assumed that a line in a range surrounded by a dotted line indicated by the symbol RD1 corresponds to the road RD1.

  In addition, the user U1 who is driving the automobile C11 performs the utterance PA12 “Dangerous during construction” while traveling on the road RD1. Thereby, the terminal device 10 collects information related to the utterance PA12 by the user U1 that “it is dangerous under construction” (step S14). For example, the terminal device 10 collects, as log information, voice information related to the utterance PA12 by the user U1 that “it is dangerous under construction”. For example, the terminal device 10 associates the position information of the user U1 at the time when the utterance PA12 is performed with the voice information regarding the utterance PA12, and collects the information as log information.

  Then, the providing device 100 acquires the log information collected by the terminal device 10 from the terminal device 10 (step S15). For example, the providing apparatus 100 acquires log information related to the utterances PA11, PA12, and the like from the terminal apparatus 10. In the example of FIG. 1, the terminal device 10-3 transmits the collected log information to the providing device 100. In the example of FIG. 1, the case where the log information collected by the terminal device 10-3 is transmitted to the providing device 100 is shown for the sake of simplicity, but the terminal device 10 utters at the time of step S <b> 13. Log information related to PA 11 may be transmitted to providing apparatus 100. Further, the terminal device 10 may transmit log information related to the utterance PA12 to the providing device 100 at the time of step S14. Further, the terminal device 10 may transmit the collected log information to the providing device 100 periodically (for example, at intervals of 5 minutes). If the collected log information satisfies a predetermined condition, the terminal device 10 collects the log information until then. The log information may be transmitted to the providing apparatus 100.

  Further, the terminal device 10 may extract only specific utterances about the voice information and transmit the extracted voice information to the providing apparatus 100. For example, the terminal device 10 may initially decrease the number of samplings and increase the number of samplings at a timing corresponding to a specific pattern such as a user performing a braking operation or a road approaching a curve. As described above, the terminal device 10 may transmit the audio information to the providing device 100 in consideration of the privacy of the user who uses the terminal device 10, the battery of the terminal device 10, the communication load, and the like.

  The providing device 100 that acquired the log information from the terminal device 10 updates the information based on the acquired log information (step S16). For example, the providing apparatus 100 is stored in the map information storage unit 121 (see FIG. 2), the feature information storage unit 122 (see FIG. 3), or the POI information storage unit 123 (see FIG. 4) based on the acquired log information. Various information (navigation information) such as POI information is changed. In the example of FIG. 1, the providing apparatus 100 deletes the information about the restaurant A stored in the POI information storage unit 123 based on the log information about the utterance PA11 or adds information indicating that the restaurant A is closed. The navigation information regarding the restaurant A is changed.

  In addition, in the example of FIG. 1, the providing apparatus 100 adds “not suitable for beginners” to the feature information corresponding to the road RD1 based on the log information regarding the utterance PA12, or corresponds to the road RD1 as illustrated in FIG. When “for beginners” is registered in the feature information, the navigation information related to the road RD1 is changed by changing “for beginners” to “not suitable for beginners”. Further, the providing apparatus 100 may add “under construction” to the feature information corresponding to the road RD1 based on the log information related to the utterance PA12. As described above, the providing device 100 changes (updates) the navigation information based on the log information acquired from the terminal device 10 used by the user U1.

  Then, the providing device 100 provides a navigation service according to the navigation information changed based on the log information. For example, the providing device 100 provides the navigation information changed based on the log information to the terminal device 10 in which the navigation application A is installed (step S17). In the example of FIG. 1, the providing device 100 provides the navigation information changed based on the log information acquired from the terminal device 10 used by the user U1 in step S17 to the terminal device 10-20 used by the user U2. . For example, the providing device 100 provides the navigation information changed when the restaurant A is closed and the road RD1 is unsuitable for beginners to the terminal device 10-20 used by the user U2. The providing apparatus 100 may provide the navigation information changed in step S17 to the terminal apparatus 10 used by the user U1.

  The terminal device 10-20 that has received the changed navigation information from the providing device 100 updates the navigation information (step S18). For example, the terminal device 10-20 updates the navigation information when the restaurant A is closed and the road RD1 is not suitable for beginners. Then, the user U2 starts the navigation application A by operating the terminal device 10-20, and then drives the automobile C12 to start moving. In response to this, the terminal device 10-20 starts guidance (navigation) based on the navigation information received in step S17. For example, in the terminal device 10-20, the navigation application A displays information indicating that the restaurant A is closed. For example, in the terminal device 10-20, the navigation application A hides the restaurant A or displays the restaurant A icon with a mark indicating that the store is closed. Moreover, when the user U1 who uses the terminal device 10-20 is a driving beginner, the route avoiding the road RD1 is guided (navigated).

  As described above, the providing device 100 changes the navigation information based on the log information acquired from the terminal device 10. Then, the providing apparatus 100 provides a navigation service according to the navigation information changed based on the log information. Thereby, the providing apparatus 100 can appropriately provide the navigation service.

  In the above-described example, the navigation information is changed based on the log information acquired from the terminal device 10 used by the user U1, but the plurality of terminal devices 10 used by each of the plurality of users collects the plurality of pieces of information. The navigation information may be changed based on the log information. For example, in this case, weighting may be performed according to the reliability of each user, and the navigation information may be changed based on the weight and log information corresponding to each user.

  As described above, the providing apparatus 100 may correct road congestion information, POI information, and the like from the voice information collected from the terminal apparatus 10. For example, the providing apparatus 100 may change various information based on the specific phrase. For example, the providing apparatus 100 may change congestion information on a predetermined road based on the voice information “crowded”. Further, for example, the providing apparatus 100 may change the corresponding POI information or delete the POI information based on the voice information “This store is crushed”. For example, the providing apparatus 100 may change the corresponding POI information based on the voice information “business hours are different”. As described above, the providing apparatus 100 may change information (POI detailed information) such as business / non-business / business hours of each POI based on the specific phrase. The providing apparatus 100 may change navigation information such as map information and road information, not limited to POI information.

  The providing apparatus 100 may extract subjective information from the collected voice information. For example, the providing apparatus 100 may extract subjective information such as “beautiful”, “good view”, and “difficult to run due to many bicycles / pedestrians”. As described above, the providing apparatus 100 may collect subjective information regarding each region (point) and extract a predetermined spot (point) that is not recognized by the service provider of the navigation application A. Also, the providing device 100 and the terminal device 10 extract phrases that are unsatisfactory in the navigation method of the navigation application A, such as “Where?”, “I don't know”, “I'm lost”, “Slow guidance”, etc. Also good. Further, the providing apparatus 100 may estimate a point where inappropriate guidance in the navigation application A is performed using the information described above.

  The providing apparatus 100 may estimate various information using the collected travel logs. For example, the providing apparatus 100 may extract an inappropriate route using the collected travel log. For example, the providing apparatus 100 may extract points where there are many deviations (reroutes) from the route presented by the navigation application A. In addition, for example, the providing apparatus 100 may estimate a road including a point with many deviations (reroutes) as a road unsuitable for a beginner or an elderly person. Further, the providing apparatus 100 may estimate a navigation difficulty point such as a point with many U-turns or a point with many turns. Further, the providing apparatus 100 may change the navigation information so as to speak an announcement for alerting if a predetermined number or more are included by clustering points where a plurality of users make U-turns.

  In the example described above, the terminal device 10 collects information on the utterances PA11 and PA12 including specific meanings. However, the utterances collected by the terminal device 10 are not limited to the above. For example, the terminal device 10 may collect information on utterances that do not include a specific meaning such as “Ah!” Or “Kya”. For example, the terminal device 10 may collect information related to utterances such as impression verbs. In this case, the terminal device 10 may collect information related to the utterance following the impression verb and the like, and may collect information related to the utterance such as the impression verb based on the information related to the utterance. Further, the terminal device 10 collects information related to subsequent utterances triggered by utterances such as “Ah!”, “Kya”, etc., and the providing device 100 and the terminal device 10 use information such as impression verbs based on the information related to the utterances. You may estimate the meaning of the information regarding the utterance. For example, the terminal device 10 may change the navigation information based on the collected log information. For example, the terminal device 10 may change navigation information in the own device based on the collected log information and provide a navigation service. Further, for example, the terminal device 10 may collect the navigation information changed in the other terminal device 10 and change the navigation information in the own device based on the navigation information. For example, the terminal device 10 may provide the navigation service by collecting the navigation information changed in the other terminal devices 10 and changing the navigation information in the own device based on the navigation information. Thus, the navigation information may be changed in the terminal device 10. In this case, the providing apparatus 100 may only provide information used to provide a navigation service in the terminal device 10 such as information used to install the navigation application A in the terminal device 10.
