(5) A recommended content provision process for selecting recommended content based on the predicted remaining travel time and providing information regarding the selected recommended content to the communication terminal device 10 of the target user as recommended information;
Execute.

  In particular, the data processing unit 350 executes a movement history registration processing unit 351 that executes a movement history registration process, a movement time prediction processing unit 353 that executes a movement time prediction process, and a viewing time registration process by executing a predetermined application. The viewing time registration processing unit 354 to be executed and the recommended content provision processing unit 354 to execute the recommended content provision processing are realized.

  For example, the movement history registration processing unit 351 of the present embodiment constitutes an acquisition unit and a movement history registration unit of the present invention, and the movement time prediction processing unit 353 constitutes a prediction unit of the present invention and registers viewing time. The processing unit 353 constitutes a measurement unit and a ratio registration unit, and the recommended content provision processing unit 354 constitutes a selection unit and a provision unit. Details of each part will be described below.

[2.2.1] Movement History Registration Processing Unit The movement history registration processing unit 351 acquires movement information of the communication terminal device 10 from the communication terminal device 10 in conjunction with the timer unit 360, and acquires the acquired movement information as a user. In association with the identification information, a movement history registration process registered and managed in the movement history information DB 331 is executed.

  Specifically, the movement history registration processing unit 351 uses the GPS function of the communication terminal device 10 to obtain current position information as movement information. Then, for example, as illustrated in FIG. 3, the movement history registration processing unit 351 associates the obtained position information, date and time information at the position, and user identification information with each other and registers them in the movement history information DB 331.

  In addition, the movement history registration processing unit 351 may determine the moving means of the user. In this case, the movement history registration processing unit 351 uses, for example, an acceleration sensor of the communication terminal device 10 and moves by walking or running when longitudinal vibrations having an amplitude of a predetermined value or more continue at a predetermined interval. It is judged that. Further, the movement history registration processing unit 351 calculates the movement speed of the user using a GPS or an acceleration sensor, and if the vibration described above is not detected in the acceleration sensor and the movement speed is less than 50 km / h average speed. It is determined that the movement is by bus or automobile, and if the movement speed is 50 km / h or more, it is determined that the movement is by train. The movement history registration processing unit 351 may register the estimation result of the movement unit in the movement history information DB 331.

[2.2.2] Travel Time Prediction Processing Unit The travel time prediction processing unit 352 determines the travel time from the current position of the target user to completion of the movement when the target user requests content provision. The predicted travel time prediction process is executed.

  Specifically, the travel time prediction processing unit 352 first determines whether or not the target user has requested content provision. This determination is based on the fact that when the target user operates the communication terminal device 10 and requests the provision of content using an application, the content provision request signal is transmitted to the information provision server device 30, so that the travel time The prediction processing unit 352 determines. When it is determined that there is a request for content provision by the target user, the travel time prediction processing unit 352 acquires the current position of the target user by using the GPS function of the communication terminal device 10 as a travel log.

  Then, the travel time prediction processing unit 352 predicts the predicted remaining travel time from the current position of the target user until the travel is completed. As a method here, for example, there are the following modes depending on past movement history information (that is, information on past habitual behavior).

(Movement time prediction process 1)
From the movement history information for each registered day of the target user, it can be determined to be the same as or the same as the moving position (that is, the movement log) at the same time of the day or a time that can be determined as the same time. When a movement history that is a movement start position and a movement end position is detected, and the detection result satisfies a predetermined condition, for example, a predetermined frequency (for example, 50%) within a predetermined number of days (for example, three months) If you have the above, for example, it is assumed that you regularly commute or go to school at the same time by train or bus, for example, the same movement start position and movement end position at the same time on the same day of the week, excluding holidays It is judged that the possibility is high.

  In this case, the travel time prediction processing unit 352 predicts the past travel time to the travel end position as the travel time to be moved when the same time on the same day of the week excluding holidays or a time that can be determined to be the same time. . The travel time here is the average travel time from the past movement start position to the movement end position.

(Movement time prediction process 2)
The movement start position and the movement end that can be determined to be the same or the same as the moving position at a time that can be determined as a different time or a different time of the day from the movement history information for each registered day of the target user When the movement history at the position is detected and the detection result has a predetermined condition, for example, when the predetermined frequency (for example, 50%) or more within a predetermined number of days (for example, three months) For example, it is assumed that the train or bus is commuting or going to school on an irregular basis, and it is determined that the same movement start position and movement end position are likely to be irregular on the same day of the week excluding holidays.

  In this case, when it is determined that the current position acquired on the same day of the week excluding holidays is located at the movement start position, the movement time prediction processing unit 352 moves the past movement time from the current position to the movement end position. Predict as travel time.

  The travel time here is the average travel time from the past movement start position to the movement end position.

(Movement time prediction process 3)
A plurality of movement end positions having different path directions with respect to a movement start position that is the same as the moving position or a position that can be determined as the same movement start position from the movement history information for each registered day of the target user. If the movement result is detected and the detection result has a predetermined condition, for example, if it has a predetermined frequency (for example, 30% each) within a predetermined number of days (for example, three months), For example, if it is estimated that you are commuting or going to school at different frequencies on a train or bus, and if it is the same day of the week, excluding holidays, it is likely that you will have the same movement start position and any movement end position To be judged.

  In this case, the movement time prediction processing unit 352 detects the movement direction after starting movement from the current position when the current position acquired on the same day of the week excluding holidays is determined to be the movement start position, and moves to the detected movement direction side. A past movement time to the movement end position to be predicted is predicted as a movement time to move from now on.

  The travel time here is the average travel time from the past movement start position to the movement end position.

(Movement time prediction process 4)
A plurality of different movements in which the directions of the routes are the same with respect to the same movement start position as the moving position or a position that can be determined as the same movement start position from the daily movement history information registered by the target user. When the movement history that is the end position is detected and the detection result satisfies a predetermined condition, for example, it has a predetermined frequency (for example, 30%) or more within a predetermined number of days (for example, three months). In this case, for example, it is presumed that people commute to school or trains at different frequencies by train or bus, and the same movement start position and any movement end position may occur on the same day of the week, excluding holidays. Judged to be high.

  In this case, when the current position acquired on the same day of the week, excluding holidays, is close to the movement start position, the movement time prediction processing unit 352 stores the past from the current position to the closest movement end position among the different movement end positions. Is estimated as the moving time to move from now on.

  The remaining movement time here is an average time of movement time from the previous movement start position to the movement end position. In addition, when the target user moves from the closest movement end position to another movement end position, the movement time prediction processing unit 352 moves the remaining movement time from the closest movement end position to the next closest movement end position. Predict as time.

(Movement time prediction process 5)
With respect to the movement history information of the target user, only movement end positions less than a predetermined frequency (for example, 30%) within a predetermined condition, for example, a predetermined number of days (for example, three months) are registered with respect to the acquired movement start position. If it is not, it is difficult to judge it as a regular move. In this case, the travel time prediction processing unit 352 predicts the average travel time from the travel start position of the target user or other users as the remaining travel time.

(Other)
In each of the above-described examples, the case has been described where the target user activates the communication terminal device 10 and starts an application at the movement start position of the past movement history information. Therefore, the travel time prediction processing unit 352 can predict the remaining travel time in the travel history information as the current remaining travel time as it is. On the other hand, for example, when the target user starts an application after moving for a certain amount of time from the movement start position, the movement time prediction processing unit 352 causes the current position to move from the movement start position to the movement end position of the movement history information. The difference between the movement time from the movement start position to the movement end position and the movement time elapsed from the movement start position to the current position is predicted as the remaining movement time.

[2.2.3] Viewing Time Registration Processing Unit The viewing time registration processing unit 353 measures the viewing time when the target user views the recommended content in conjunction with the timer unit 360, and registers and manages it in the viewing time management DB 333. The viewing time registration process is executed.

  Specifically, the viewing time registration processing unit 353 registers and manages the content ID and viewing time of the recommended content viewed by the target user in the viewing time management DB 333 as shown in FIG. The viewing time registration processing unit 353 averages when other users view the same content as the recommended content registered in the viewing time management DB 333 when the target user requests provision of recommended content. The ratio of the viewing time of the target user to the viewing time is temporarily registered and managed in the viewing time management DB 333.

[2.2.4] Recommended Content Provision Processing Unit The recommended content provision processing unit 354 obtains the remaining travel time predicted by the travel time prediction processing unit 352 when there is a request for content provision by the target user. The recommended content providing process is performed in which recommended content is selected based on the length of the remaining travel time, and information related to the selected recommended content is provided as recommended information to the communication terminal device 10 of the target user.

  The recommended content provision processing unit 354 calculates a ratio of the viewing time of the recommended content that the target user has viewed in the past to the average viewing time when the plurality of other users viewed the same recommended content, as shown in FIG. The average viewing time length and the ratio are temporarily stored in the viewing time management DB 333 in association with each other. The recommended content provision processing unit 354 calculates an average ratio as an average value of the ratios of the calculated target user with respect to the average viewing time. The recommended content provision processing unit 354 calculates the expected viewing time of the target user in the recommended content by adding up the average viewing time and the average ratio of the recommended recommended content recorded in the content management DB 332.

  Then, the recommended content provision processing unit 354 selects, for example, recommended content having a length equal to or shorter than the remaining travel time predicted for the expected viewing time and close to the remaining travel time. Further, the recommended content provision processing unit 354 may select the recommended content, for example, only unviewed content or regardless of whether or not the content is viewed. Further, the recommended content provision processing unit 354 may refer to the movement history information DB 331 to estimate the moving means of the target user and select the recommended content corresponding to the estimated moving means.

  Then, the recommended content provision processing unit 354 provides information related to the selected recommended content to the communication terminal device 10 of the target user in a list format. The list here can be set as appropriate, for example, in the order of the longest expected viewing time, or by genre. The target user can browse the list and select and view the content he / she wants to view. Since the selected content is shorter than the remaining movement time until moving to the movement end position and close to the remaining movement time, the target user can watch early until moving to the movement end position. The recommended content can be viewed without wasting time.

[3] Operation of Communication System [3.1] Movement History Registration Process First, the movement history registration process of the information providing server device 30 will be described with reference to FIG. FIG. 5 is a flowchart showing the movement history registration process executed in the information providing server device 30 of this embodiment.

  First, the movement history registration processing unit 351 determines whether movement information has been received from the communication terminal device 10 of the target user (step S101). When the movement history registration processing unit 351 determines that movement information has been received from the communication terminal device 10, the movement history registration processing unit 351 registers the movement information in the movement history information DB 331 (step S102), and ends this operation.

  As described above, by executing the movement history registration process, in the information providing system 1 of the present embodiment, the normal movement history information of the target user is recorded in the movement history information DB 331.

[3.2] Travel Time Prediction Processing and Recommended Content Providing Processing Next, travel time prediction processing and recommended content provision processing executed in the information providing server device 30 of this embodiment will be described with reference to FIG. FIG. 6 is a flowchart showing the travel time prediction process and the recommended content provision process executed in the information provision server device 30. The flowchart showing the travel time prediction process and the recommended content providing process can be executed in parallel with the flowchart showing the travel history registration process described above.

  First, in the information providing server device 30, the travel time prediction process 352 determines whether or not a request for providing recommended content has been received from the communication terminal device 10 of the target user (step S201). When the travel time prediction process 352 determines that a request for provision of recommended content has been received from the communication terminal device 10, the travel time prediction process 352 acquires the current location movement log of the communication terminal device 10 from the travel history registration processing unit 351 (step S 202). . The travel time prediction process 352 predicts the remaining travel time from the current position to the travel end position based on the travel history information DB 331 and the travel log (step S203). As described above, steps S201 to S203 constitute the travel time prediction process.

  Next, the recommended content provision processing unit 354 selects a recommended content candidate with reference to the content management DB 332, and refers to the viewing time management DB 333 for the selected candidate recommended content to obtain the average ratio of the target users. Based on this, the expected viewing time of each recommended content is calculated (step S204).

  Next, the recommended content provision processing unit 354 compares the remaining travel time with the expected viewing time of the recommended content, and selects the recommended content that has an expected viewing time shorter than the remaining travel time and close to the remaining travel time. (Step S205).

  Next, the recommended content provision processing unit 354 transmits the selected recommended content list to the communication terminal device 10 to be displayed (step S206). The display order of the list here is, for example, in the order of longest expected viewing time.

  Next, the recommended content provision processing unit 354 determines whether a selection result indicating which recommended content has been selected is received from the communication terminal device 10 (step S207). At this time, if the recommended content provision processing unit 354 determines that the selection result has been received from the communication terminal device 10, the recommended content provision processing unit 354 provides information (for example, URL) regarding the selected recommended content (step S208). End the operation.

  As described above, by executing the travel time prediction process and the recommended content providing process, the recommended content is provided to the communication terminal device 10 in the information providing system 1 of the present embodiment.

[3.3] Viewing Time Registration Processing Next, viewing time registration processing executed in the information providing server device 30 of the present embodiment will be described with reference to FIG. FIG. 7 is a flowchart showing viewing time registration processing executed in the information providing server device 30. The flowchart showing the viewing time registration process can be executed in parallel with the flowchart showing the movement history registration process described above.

  First, the viewing time registration processing unit 353 determines whether information regarding recommended content is provided by the recommended content provision processing unit 354 (step S301). At this time, if the viewing time registration processing unit 353 determines that the information related to the recommended content is provided, the viewing time registration processing unit 353 starts measuring the viewing time (step S302).

  Then, the viewing time registration processing unit 353 determines whether or not viewing has ended (step S303). When the viewing time registration processing unit 353 determines that the viewing has ended, the viewing time registration processing unit 353 stops the measurement of the viewing time, registers the measurement result in the viewing time management DB 333 (step S304), and ends this operation.

  As described above, in the information providing system 1 of the present embodiment, the past habitual movement history information of the target user is registered in the movement history information DB 331, and the remaining movement time is predicted based on the movement history information. Since it is possible to provide the recommended content that is optimal for the estimated remaining travel time, it is possible to prevent the target user from moving before the content ends and the viewing is interrupted, and the content is recommended. It is possible to accurately recommend and provide content that matches the user's movement status.

[4] Modification [4.1] Modification 1
In the above embodiment, each DB is provided in the information providing server device 30, and these DBs are managed and controlled only by the information providing server device 30. However, each DB management and control entity is separately provided. A simple computer system may be used. For example, in the above embodiment, the network service for performing the movement history registration process, the viewing time registration process, and the recommended content providing process may be executed by different server devices.

[4.2] Modification 2
In the above embodiment, the information providing server device 30 includes the viewing time management DB 333 and the viewing time registration processing unit 353, and selects recommended content by reflecting the ratio of the viewing time of the target user to the average viewing time of other users. However, the recommended content may be selected using the average viewing time of other users as it is without considering such a ratio. In this case, since the information providing server device 30 does not need to include the viewing time management DB 333 and the viewing time registration processing unit 353, the information providing server device 30 can be reduced in size and speeded up.

[4.3] Modification 3
In the above embodiment, the genre of recommended content is not particularly considered. For example, the genre of recommended content that the target user has viewed in the past is registered in the viewing time management DB 333 as a viewing history, and movement history information is stored. It may be used for selection of recommended content in association with. Thus, for example, when moving from the A point to the B point in the morning, the content of the news genre is often viewed, and when moving from the B point to the A point at night, the content of the electronic book genre is viewed. It is possible to obtain a habitual viewing history such as that often. By using the genre obtained in this way for selection of recommended content, it is possible to more accurately recommend and provide content that matches the movement status of a user who desires content recommendation.

[4.4] Modification 4
In the above embodiment, for example, there is no particular consideration for the case where there is no other user's average viewing time, such as new news, but for example, the correlation between the number of characters of past content and viewing time is obtained, A rough viewing time may be estimated from the number of characters of new news.
