<1. Overview>
First, an outline of a congestion state determination method according to an embodiment of the present disclosure described below will be described with reference to FIGS. FIG. 1 is an explanatory diagram illustrating an overview of a congestion state determination method according to an embodiment of the present disclosure. FIG. 2 is a graph showing an example of normal vibration detection data. FIG. 3 is a graph showing an example of shaking detection data at the time of congestion.

  The congestion state determination method according to an embodiment of the present disclosure determines whether each user is in a congestion state based on shake detection data acquired by a terminal device carried by the user. At this time, the congestion state means that the user is actually difficult to move due to the influence of the congestion.

  Based on this definition, for example, even if the density of people in an area is low, it is congested for people lining up in the area, and only passes by the side of the matrix. It is not crowded for people. According to the congestion state determination method according to an embodiment of the present disclosure, the difference between the two can be distinguished. For example, in the method of determining the congestion state based on the distribution of the number of people in the area, it is determined that the congestion state is not simply provided that there are not many people in the area. For this reason, there is no distinction between those who are in line and those who pass by the line.

  Moreover, when trying to detect each user's state, it is possible to use the moving speed of a user, for example. However, if the user's speed is simply used to reduce the speed, it is determined that the user is congested. If the user is slowly moving on a moving sidewalk or escalator, the user may be erroneously determined to be congested.

  Therefore, a congestion state determination method according to an embodiment of the present disclosure determines whether or not a user is in a congestion state based on shake detection data acquired by a terminal device carried by the user. The shake detection data is acquired by a sensor (for example, an acceleration sensor, a gyro sensor, an atmospheric pressure sensor, etc.) that can detect a shake provided in the terminal device.

  As shown in FIG. 1, the pitch at which the user walks is different between the normal time and the crowded time. Compared to the normal pitch, the pitch during congestion is slow. An example of the shake detection data at this time is shown in FIGS. As can be seen from a comparison between FIG. 2 and FIG. 3, the pitch at which the user appears in the phase of the shake detection data is slower in the crowded state than in the normal state. The amplitude of the shake detection data is also different between the normal time and the congestion time. Next, an embodiment of the congestion state determination device according to the present disclosure that determines the congestion state using this difference will be described.

  In the present specification and drawings, a plurality of constituent elements having substantially the same functional configuration may be distinguished by attaching different alphabets after the same reference numeral. For example, the terminal device 100 is distinguished for each embodiment as a terminal device 100a, a terminal device 100b, and a terminal device 100c. However, when it is not necessary to particularly distinguish each of a plurality of constituent elements having substantially the same functional configuration, only the same reference numerals are given. For example, when there is no need to particularly distinguish the terminal device 100a, the terminal device 100b, the terminal device 100c, and the like, they are simply referred to as the terminal device 100.

The terminal device 100 may be configured to be able to acquire various types of information associated with the location information by appropriately accessing the map DB 261 included in the external device. The map DB 261 may be configured to appropriately acquire map information around the current position from an external device.

(2-3. Shake detection data)
Here, the details of the shake detection data supplied by the shake detection unit 101 will be considered with reference to FIGS. FIG. 7 is a graph showing an example of normal vibration detection data (detected by an acceleration sensor) when the terminal device is carried in a pocket. FIG. 8 is a graph showing an example of normal vibration detection data (detected by an acceleration sensor) when the terminal device is carried by hand. FIG. 9 is a graph showing an example of shaking detection data (detected by an acceleration sensor) at the time of congestion. FIG. 10 is a graph showing an example of normal vibration detection data (detected by a gyro sensor) when the terminal device is installed on the waist. FIG. 11 is a graph showing an example of normal shake detection data (detected by a gyro sensor) when the terminal device is carried in a pocket. FIG. 12 is a graph showing an example of normal shake detection data (detected by a gyro sensor) when the terminal device is carried by hand.

  First, referring to FIG. 7 to FIG. 9, with respect to the shake detection data detected using the acceleration sensor, when the terminal device 100 is carried in a pocket, when the terminal device 100 is carried by hand, and at the time of congestion Shake detection data is shown. At this time, when the terminal device 100 is carried in a pocket and carried around, the amplitude of the shake detection data is larger when the terminal device 100 is carried around and carried in the pocket. However, referring to FIG. 9, the amplitude of the shake detection data in FIG. 7 and the amplitude of the shake detection data in FIG. 9 are different from the difference between the amplitude of the shake detection data in FIG. 7 and the amplitude of the shake detection data in FIG. And the difference between the amplitude of the shake detection data in FIG. 8 and the amplitude of the shake detection data in FIG. 9 is larger. Therefore, in this case, the shake detection data can be used for the congestion determination regardless of the method of carrying the terminal device 100.

  Referring to FIGS. 7 to 9, regarding the shake detection data detected by the acceleration sensor, especially the shake detection data in the vertical direction (vertical direction) is not easily affected by how the terminal device 100 is carried. In addition, since the vertical shake detection data easily reflects the influence of the user's walking pitch, it is preferable that the congestion determination unit 107 determines the congestion based on the amplitude and pitch values of the vertical shake detection data. .

  10 to 12, with respect to the shake detection data detected using the gyro sensor, when the terminal device 100 is installed on the waist, when the terminal device 100 is carried in a pocket, and when the terminal device 100 is carried around, The shaking detection data when the is carried by hand is shown. 10 to 12, the amplitude of the shake detection data detected using the gyro sensor varies greatly depending on how the terminal device 100 is carried. Therefore, the congestion determination unit 107 performs the congestion determination using the pitch without using the amplitude of the vibration detection data when performing the congestion determination based on the vibration detection data detected using the gyro sensor. Is desirable. Further, among the shake detection data detected using the gyro sensor, the shake detection data indicating the yaw angle is relatively less affected by how the terminal device 100 is held, and easily reflects the influence of the user's walking pitch (two steps). Therefore, it is preferable that the congestion determination unit 107 determines the congestion based on the pitch value of the shake detection data indicating the yaw angle.

  Further, the shake detection data used for the congestion determination may be detected by an atmospheric pressure sensor. The resolution and sampling period of the current barometric pressure sensor are not yet sufficient for measuring the walking pitch. However, if a barometric sensor having a performance capable of detecting the vertical movement accompanying walking is used, the shake detection data detected by the barometric sensor can be used for the congestion determination.

  In addition, in order to remove noise included in the shake detection data acquired using the atmospheric pressure sensor, only a band (for example, 1.5 to 3.5 Hz) for detecting the walking pitch is extracted using a filter. It is preferable. For example, atmospheric pressure fluctuates greatly just by passing a car or opening and closing windows. For this reason, it is important to remove such noise components.

(2-4. Example of operation)
Next, an operation example of the terminal device 100a according to the first embodiment of the present disclosure will be described with reference to FIGS. FIG. 13 is a flowchart illustrating an example of a congestion determination process according to an embodiment of the present disclosure. FIG. 14 is a flowchart illustrating another example of the congestion determination process according to the embodiment. FIG. 15 is a flowchart illustrating an operation of the terminal device according to the first embodiment of the present disclosure.

  Here, two congestion determination processes will be described. In the congestion determination process shown in FIG. 13, the determination result is only used when providing content, which will be described later, and is not stored. Further, in the congestion determination process shown in FIG. 14, the determination result is stored together with the position information.

  First, referring to FIG. 13, the shake detection unit 101 acquires shake detection data (S101). Then, the shake detection unit 101 supplies the acquired shake detection data to the measurement unit 103. The measuring unit 103 measures the amplitude and pitch of the supplied shake detection data (S103). The measurement unit 103 supplies the amplitude and pitch of the shake detection data obtained by measurement to the congestion determination unit 107. The congestion determination unit 107 compares the current amplitude and pitch values supplied from the measurement unit 103 with the amplitude and pitch values during normal walking acquired from the normal walking learning unit 105 (S105).

  Then, the congestion determination unit 107 determines whether the value supplied from the measurement unit 103 has a smaller amplitude than the normal value by a threshold value or more (S107). When the amplitude is smaller than the threshold value than normal, the congestion determination unit 107 determines whether the value supplied from the measurement unit 103 is smaller in pitch than the threshold value than normal (S109). . Then, when it is determined that the pitch is smaller than the threshold than the normal time, the congestion determination unit 107 determines that the congestion state is present (S111).

  Here, the congestion determination unit 107 determines the congestion degree by determining whether or not it is in a congestion state using a threshold, but the present technology is not limited to such an example. For example, the normal pitch and amplitude may be compared with the current pitch and amplitude, and the degree of congestion may be determined stepwise or continuously according to the difference value. In addition, the congestion determination unit 107 stores the normal fluctuation as a two-dimensional distribution of amplitude and pitch (for example, average value and variance), and the probability depends on how far the current fluctuation is from the normal distribution. Alternatively, the degree of congestion may be determined.

  Next, another example of the congestion determination process will be described with reference to FIG. First, the shake detection unit 101 acquires shake detection data (S201). Then, the shake detection unit 101 supplies the acquired shake detection data to the measurement unit 103. The measuring unit 103 measures the amplitude and pitch of the supplied shake detection data (S203). The measurement unit 103 supplies the amplitude and pitch of the shake detection data obtained by measurement to the congestion determination unit 107. The congestion determination unit 107 compares the current amplitude and pitch values supplied from the measurement unit 103 with the amplitude and pitch values during normal walking acquired from the normal walking learning unit 105 (S205).

  Then, the congestion determination unit 107 determines whether the value supplied from the measurement unit 103 has a smaller amplitude than the normal value by a threshold value or more (S207). When the amplitude is smaller than the threshold value than normal, the congestion determination unit 107 determines whether the value supplied from the measurement unit 103 is smaller in pitch than the threshold value than normal (S209). . Then, when it is determined that the pitch is smaller than the threshold than the normal time, the congestion determination unit 107 determines that the congestion state is present (S211).

  If the congestion determination unit 107 determines that the user of the terminal device 100a is in a congested state, the congestion determination unit 107 causes the position information acquisition unit 115 to acquire the current position information (S213). Then, the congestion determination unit 107 updates the record of the location and time determined to be in the congestion state (S215). At this time, the congestion determination unit 107 may measure and record the duration of the state determined as the congestion state.

  Note that, using the result of the congestion determination process shown in FIGS. 13 and 14, the terminal device 100a may operate as in the flowchart shown in FIG. That is, the congestion determination process in step S301 may be the congestion determination process shown in FIG. 13 or the congestion determination process shown in FIG. When the congestion degree determination process (S301) is executed, the content providing unit 113 determines whether or not the determination result is a congestion state (S303). When it is determined that the content providing unit 113 is in the congested state, the content providing unit 113 selects the content according to the congested state (S305). The content providing unit 113 provides the selected content (S307).

  Details of the content selection in step S305 will be described here. For example, when it is determined that the user is congested, the content providing unit 113 may select content that reduces the user's stress. For example, the content that reduces the user's stress may be music content or video content that is considered to be effective for stress relief by music tone analysis or video analysis. At this time, various algorithms for determining content attributes may be used for selecting content.

  Further, when in a crowded state, it is considered that the user is more interested in the content provided by the terminal device 100 than when walking at a normal pace. For this reason, the content providing unit 113 may provide content to the user by a push method when it is determined that the state is congested. In addition, the content providing unit 113 may change the frequency of providing content to the user by this push method according to the congestion state. The content providing unit 113 can provide content to the user more frequently than usual when the content providing unit 113 is congested.

  Note that here, the content that matches the congestion state is selected only when it is determined that the congestion state is present, but the present technology is not limited to such an example. For example, even when it is determined that the state is not congested, the content may be selected according to the determination result.

(2-5. Examples of effects)
The terminal device 100a according to the first embodiment has been described above. According to such a configuration, based on the shake detection data acquired by the terminal device 100a owned by the user, the user's individual congestion state can be determined by comparing at least the walking pitch with that during normal walking. At this time, by detecting the walking pitch from the shake detection data, it is possible to detect that the user is walking and that the pace has decreased. For example, in the method of simply detecting that the speed has dropped, there is a possibility that it is erroneously determined that the vehicle is congested even when the speed is lowered while riding on a moving sidewalk or escalator. However, the terminal device 100a according to the present embodiment is not determined to be in a congested state when the vehicle is riding on a vehicle and the speed is decreasing, and can accurately determine that it is in a congested state when walking.

  At this time, the terminal device 100a performs the congestion determination based on the difference from the normal walking. When the congestion is simply determined by a change in speed, an old man who is originally slow is always determined to be in a crowded state. However, according to the terminal device 100a, since it determines based on the difference with the time of normal walking, the precision of congestion determination improves.

  Furthermore, by using the amplitude of the shake detection data for the congestion determination, the accuracy of the congestion determination is improved. For example, the stride is small for a tall person to go slowly. At this time, if the stride is reduced, the vertical movement of the body is reduced, so that the amplitude of the detected shake detection data is reduced. By using this change in stride for congestion determination, the accuracy of congestion determination is improved.

  According to this congestion determination, as described above, it is possible to accurately determine the congestion during walking. For this reason, it is effective to use the congestion determination result for the timing of providing content to the user and the selection of the content to be provided. For example, during normal walking, even if the content providing unit 113 of the terminal device 100a makes a push notification, there is a high possibility that the user will not notice. However, when the user is congested, the user is moving at a low speed and proceeds in accordance with the surrounding movement, so that there is a very high possibility that the user can afford to look at the screen of the terminal device 100a. Therefore, when the push notification is performed in a crowded state, the user is more likely to be interested in the notified content than when the push notification is performed during normal walking.

<3. Second Embodiment (Example of Uploading Congestion Information to Server)>
(3-1. System configuration example)
Next, a configuration example of the congestion information generation system according to the second embodiment of the present disclosure will be described with reference to FIG. FIG. 16 is a configuration diagram of a congestion information generation system according to the second embodiment of the present disclosure.

  The congestion information generation system 1 mainly includes a terminal device 100b, a congestion degree map generation server 200b, and a service server 300b. Here, although the congestion degree map generation server 200b and the service server 300b are separate servers, the present technology is not limited to such an example. For example, the congestion degree map generation server 200b and the service server 300b may be configured as an integrated server.

  The terminal device 100b is an example of a congestion state determination device that determines the degree of congestion from the shake detection data. When the terminal device 100b is determined to be in the congestion state, the terminal device 100b acquires the current position information and sends the position information to the congestion degree map generation server 200b. Upload. Moreover, the terminal device 100b can acquire a congestion degree map from the congestion degree map generation server 200b. For example, a congestion degree map indicating the degree of congestion around the current position may be acquired based on the current position information. Further, the terminal device 100b may be able to acquire information by requesting the service server 300 to provide a service.

  The congestion degree map generation server 200b has a function of generating a congestion degree map by acquiring location information that is in a congested state from a plurality of terminal devices 100b. For example, the congestion degree map may be obtained by superimposing the position of the terminal device 100b in the congestion state on the map. At this time, in addition to the position of the terminal device 100b, the congestion degree map generation server 200b may indicate the traveling direction of the terminal device 100b, that is, the direction of congestion on the congestion degree map.

  The service server 300b is a server that generates information to be provided to the user based on the congestion degree map. For example, the service server 300b can search and provide a route for the user to avoid congestion based on the congestion degree map. Alternatively, the service server 300b can predict and provide the terminal device 100b with the time until the congestion is eliminated based on the past congestion state duration.

(3-2. Functional configuration example of terminal device)
Next, a functional configuration example of the terminal device 100b according to the second embodiment of the present disclosure will be described with reference to FIG. FIG. 17 is a functional configuration diagram of the terminal device according to the embodiment. The terminal device 100b includes a shake detection unit 101, a measurement unit 103, a normal walking learning unit 105, a congestion determination unit 107, a storage unit 109, a content provision unit 113, a position information acquisition unit 115, and a transmission / reception unit 117. And mainly.

  Here, components different from the terminal device 100a according to the first embodiment will be mainly described, and the description of the same parts as the terminal device 100a will be omitted.

  The terminal device 100b can acquire the congestion degree map from the congestion degree map generation server 200b via the transmission / reception unit 117. The congestion determination unit 107 may adjust a threshold used for the congestion determination based on the acquired information on the congestion degree map. For example, if it is found from the congestion degree map that the terminals around the terminal device 100b are determined to be in a congested state, the terminal device 100b is likely to be congested. For this reason, when the threshold value is not exceeded and the surroundings are in a congested state, it is desirable for the terminal device 100b to adjust the threshold value so as to be determined as a congested state at that time. In addition, the content providing unit 113 can provide the user with content acquired from an external server via the transmission / reception unit 117. For example, the content providing unit 113 may provide the user with the content acquired from the service server 300b.

  Further, when it is determined that the congestion state is the congestion state, the congestion determination unit 107 can transmit the current position information to the congestion degree map generation server 200 via the transmission / reception unit 117. Here, the current position information can include the direction of congestion calculated from the traveling direction of the user. At this time, the congestion determination unit 107 may transmit information for identifying the terminal device 100b to the congestion degree map generation server 200.

(3-3. Example of operation)
Next, an operation example of the congestion information generation system according to the second embodiment of the present disclosure will be described with reference to FIGS. 18 and 19. FIG. 18 is a sequence diagram illustrating an example of the operation of the congestion information generation system according to the embodiment. FIG. 19 is a sequence diagram illustrating another example of the operation of the congestion information generation system according to the embodiment. The operation example in FIG. 18 and the operation example in FIG. 19 are different in the timing at which the terminal device 100b transmits information related to the congestion state to the congestion degree map generation server 200b.

  Referring to FIG. 18, first, the terminal device 100b executes a congestion determination process (S401). Then, the congestion determination unit 107 determines whether or not it is determined to be in a congestion state (S403). If it is determined to be in the congestion state, the congestion degree map generation server 200b stores the current location information and the terminal. Information for identifying the device 100b is transmitted (S405).

  Then, the congestion degree map generation server 200b that has received the current position information and the terminal identification information of the terminal device 100b updates the record of the congestion state duration, location, and time for the terminal device 100b (S407). .

  On the other hand, the terminal device 100b executes the congestion determination process again (S409). Then, the congestion determination unit 107 determines whether the congestion state is continuing (S411). When the congestion state is continuing, the congestion determination unit 107 transmits the current position information and information for identifying the terminal device 100b to the congestion degree map generation server 200b again. The processes in steps S405 to S411 are repeated until the terminal device 100b comes out of the congestion state.

  Note that the congestion determination processing in steps S401 and S409 may be, for example, the congestion determination processing illustrated in FIG. Alternatively, the congestion determination process in step S401 and step S409 may be the congestion determination process shown in FIG.

  Further, the congestion information generation system according to the present embodiment may operate as shown in FIG. In this case, the terminal device 100b first executes a congestion determination process (S501). Here, the congestion determination process in step S501 may be, for example, the congestion determination process shown in FIG. Alternatively, the congestion determination process in step S501 may be the congestion determination process shown in FIG.

  Then, the congestion determination unit 107 determines whether or not the terminal device 100b has exited the congestion state (S503). Then, when the terminal device 100b exits the congestion state, the congestion determination unit 107 acquires the duration time of the congestion state and the current position information and transmits them to the congestion degree map generation server 200b (S505). The congestion level map generation server 200b records the duration, place, and time of the congestion state (S507).

(3-4. Examples of effects)
The congestion information generation system according to the second embodiment of the present disclosure has been described above. In the present embodiment, the terminal device 100b can transmit information indicating that it is in a congestion state to the congestion degree map generation server 200b. As described above, the congestion degree map is used to adjust a threshold value used for congestion determination. Thereby, the accuracy of congestion determination improves. An example of the congestion degree map provided here and the service provided by the service server are common to the third embodiment described below, and will be described later as an application example.

<4. Third Embodiment (Example of Performing Congestion Determination on Server Side)>
(4-1. System configuration example)
Next, the configuration of the congestion information generation system according to the third embodiment of the present disclosure will be described with reference to FIG. FIG. 20 is a configuration diagram of a congestion information generation system according to the third embodiment of the present disclosure.

  The congestion information generation system according to the present embodiment mainly includes a terminal device 100c, a congestion degree map generation server 200c, and a service server 300c. In the first and second embodiments, the terminal device 100 executes the congestion determination process. In the present embodiment, the shake detection data acquired by the terminal device 100c is transmitted to the congestion degree map generation server 200c, and the congestion determination process is performed in the congestion degree map generation server 200c.

(4-2. Functional configuration example)
Next, the functional configuration of the terminal device 100c and the congestion degree map generation server 200c in the congestion information generation system according to the present embodiment will be described with reference to FIG. FIG. 21 is a functional configuration diagram of the congestion information generation system according to the embodiment.

  The terminal device 100c mainly includes a shake detection unit 101, a content providing unit 113, a position information acquisition unit 115, and a transmission / reception unit 117. The transmission / reception unit 117 transmits the shake detection data detected by the shake detection unit 101 to the congestion degree map generation server 200c.

  The congestion level map generation server 200c mainly includes a transmission / reception unit 201, a measurement unit 203, a normal walking learning unit 205, a congestion determination unit 207, a storage unit 209, and a congestion level map generation unit 211.

  Here, the measurement unit 203 has the same function as the measurement unit 103. The normal walking learning unit 205 has the same function as the normal walking learning unit 205. The congestion determination unit 207 has the same function as the congestion determination unit 107. The storage unit 209 has the same function as the storage unit 109.

  However, since the congestion degree map generation server 200c stores information on the congestion state for the plurality of terminal devices 100c, the storage unit 209 may store information on the congestion state together with information for identifying the terminal device 100c. preferable. At this time, the information for identifying the terminal device 100c only needs to be able to identify that the information is about the same terminal device 100c, and may not be information specifying the terminal device 100c or its user. In consideration of the privacy of the user, it may be preferable that the terminal device 100c or the information cannot identify the user.

(4-3. Example of operation)
Next, an example of the operation of the congestion information generation system according to this embodiment will be described with reference to FIG. FIG. 22 is a sequence diagram showing an example of the operation of the congestion information generation system according to the embodiment.

  First, the shake detection unit 101 of the terminal device 100c acquires shake detection data (S601). Then, the position information acquisition unit 115 acquires the current position information of the terminal device 100c (S603). The terminal device 100c transmits the acquired shake detection data and position information to the congestion degree map generation server 200c via the transmission / reception unit 117 (S605). The congestion degree map generation server 200c that has received the shake detection data and the position information executes congestion determination and recording processing (S607). Note that the congestion determination and recording process in step S607 may be, for example, the process illustrated in FIG.

(4-4. Examples of effects)
As described above, according to the congestion information generation system according to the present embodiment, the congestion determination process is executed on the server side. For this reason, there exists an effect that the processing load of the terminal device 100c becomes light. That is, the congestion determination process can be performed also for the terminal device 100c having a low processing capability.

<5. Application example>
Next, an example of a service that can be provided using the congestion information generation system according to the second and third embodiments of the present disclosure will be described with reference to FIGS. 23 to 28. 23 to 28 are explanatory diagrams illustrating an example of congestion information provided by the congestion information generation system according to the second and third embodiments of the present disclosure.

  For example, the congestion degree map generation server 200 may provide the congestion degree map shown in FIG. Here, it can be seen that congestion occurs in the vicinity of area A1 and area A2. At this time, for example, the service server 300 may search for a route for avoiding the area A1 and the area A2 that are further congested in addition to the congestion degree map and provide it to the user of the terminal device 100.

  In addition, as illustrated in FIG. 24, the service server 300 may provide information on the estimated waiting time to the user terminal devices 100 arranged in a matrix in the store S. For example, the service server 300 may estimate the waiting time from the information on the continuation time of the congestion state from the same position in the same time zone on the same day in the past, and provide it to the user. Further, the service server 300 may provide the user terminal device 100 with information on the store S at the end of the queue. For example, when the shop S is a restaurant, the service server 300 may provide menu information to the user. Alternatively, the service server 300 may provide recommended menu information to the user.

  Alternatively, as shown in FIG. 25, when the terminal devices 100 determined to be congested in a specific area A3 are crowded, the direction D of the monitoring camera C is directed toward the area A3. Also good. Alternatively, this congestion information may be used to dispatch security guards to the area A3 where the terminal devices 100 determined to be in a crowded state are dense. For example, as shown in the screen 13 shown in FIG. 26, by displaying a screen showing an area where the congested terminal devices 100 are crowded on the map on the display unit of the terminal device having the security guard, It can be properly placed where it is needed. For example, it can respond to sudden abnormal situations such as holding a guerrilla live.

  In addition, as shown in FIG. 27, when a person leaves the previous station, a lot of congestion is detected in the vicinity of the train door (area A4) because many people get on the train to some extent. Indicates congestion when getting on and off the train. For this reason, the service server 300 can specify the vehicle on which the user of each terminal device 100 gets in from the position of the terminal device 100 in a congested state. For example, the service server 300 may use this congestion information to guide a user to a vacant vehicle on the screen 15 shown in FIG.

  The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings, but the present technology is not limited to such examples. It is obvious that a person having ordinary knowledge in the technical field to which the present disclosure belongs can come up with various changes or modifications within the scope of the technical idea described in the claims. Of course, it is understood that these also belong to the technical scope of the present disclosure.

  For example, in the above embodiment, the congestion determination is performed based on the pitch and amplitude values of the shake detection data, but the present technology is not limited to such an example. For example, the congestion determination may be performed based only on the pitch. At this time, the congestion determination may be performed based on the difference between the one-dimensional distribution of the pitch during normal walking calculated based on the past vibration detection data and the pitch acquired by the acquisition unit. Further, the congestion determination may be performed based on a difference amount between the pitch acquired by the acquisition unit and the pitch during normal walking. For example, when the amplitude of the shake detection data is less dependent on how the terminal device 100 is held and the influence of the degree of congestion is easily reflected, it is desirable to determine the congestion using the amplitude value in addition to the pitch.

  For example, in the third embodiment, the congestion map generation server that generates the congestion map executes the congestion determination process, but the present technology is not limited to such an example. For example, a server separate from the congestion degree map generation server may execute the congestion determination process.

  In the present specification, the steps described in the flowcharts or sequence diagrams are not limited to the processes performed in chronological order in the described order, but are not necessarily processed in chronological order, either in parallel or individually. It also includes processing that is executed automatically. Further, it goes without saying that the order can be appropriately changed even in the steps processed in time series.
