[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0015] FIG. 1 shows the configuration of a video viewing system according to an embodiment of the present invention.

[0016] As shown in the diagram, the video viewing system according to the embodiment of the present invention is configured by connecting a server device 1 and a terminal device 2 wirelessly or by wire via a communication network 3 such as the Internet. Note that the terminal device 2 can be any of a variety of devices, such as a smartphone, a tablet device, a notebook personal computer, or a desktop personal computer.

[0017] In such a configuration, in the video viewing system, the server device 1 stores in advance a plurality of video parts that constitute a plurality of scenarios that branch off during viewing, and also stores in association with each other information on a questionnaire to be conducted after viewing each video part.

[0018] The server device 1 first encourages viewing of a common video, conducts a questionnaire after viewing the first video, and then encourages viewing of the corresponding video part (challenge video) based on the results of the questionnaire.The server device 1 then performs a predetermined evaluation based on the results of the questionnaire and points awarded in the video viewing process, selects a final video part (suggested video) based on the results of the evaluation, and encourages viewing of the final video part.

[0019] The scenario constructed from the video viewing is then associated with information on whether the video viewing based on the scenario led to attracting customers (for example, appointments), and this information is stored and used as learning data when constructing an evaluation model.

[0020] Therefore, under an effective scenario that will attract customers, it is possible to encourage video viewing and improve the customer attraction rate.

[0021] FIG. 2 shows the configuration of the server device in the video viewing system according to the embodiment of the present invention.

[0022] As shown in the figure, the server device 1 has a control unit 11, a communication I / F 12, and a storage unit 13. The control unit 11, the communication I / F 12, and the storage unit 13 are communicably connected via a system bus. In addition to these components, the server device 1 may also have input units such as a keyboard and a mouse, and a display unit such as a liquid crystal display for displaying various information.

[0023] The communication I / F 12 is realized by, for example, an NIC, and is connected to a communication network 3 such as the Internet via a wired or wireless connection, and is a communication interface for communicating with the terminal device 2, etc. The storage unit 13 is realized by a semiconductor memory element such as RAM or flash memory, an HDD, an optical disk device, etc., and stores in advance the programs to be executed by the control unit 11. The storage unit 13 has a user information storage unit 14, a video information storage unit 15, a questionnaire information storage unit 16, and an evaluation storage unit 17.

[0024] The user information storage unit 14 stores attribute information such as the user's name, age, sex, email address, and phone number, as well as video viewing history information and payment information, linked to the user ID. The video information storage unit 15 stores, for each of the challenge video and the proposed video, the points awarded for viewing the video, the video data, and the survey ID of the survey to be conducted after viewing, in association with each other.

[0025] More specifically, in the video information storage unit 15, for the assignment video, the assigned points, video data, and survey ID, etc. are stored linked to the video ID, as shown in Figure 4(a), and for the suggested video, the selection criteria, video data, and survey ID, etc. are stored linked to the video ID, as shown in Figure 4(b).

[0026] The survey information storage unit 16 stores survey data linked to a survey ID. The evaluation storage unit 17 stores information such as the viewing date and time, the viewed assignment video and survey results (including free responses and comments), the proposed video, comments, the final survey results, points awarded for viewing, and whether or not an audience was attracted (for example, an appointment was made), as shown in Fig. 5. In other words, a scenario related to video viewing and the results of viewing based on the scenario are stored.

[0027] The control unit 11 is realized by a CPU, an MPU, etc. The control unit 11 is configured by an integrated circuit such as an ASIC, an FPGA, etc. By executing programs stored in the storage unit 13, the control unit 11 functions as a transmission unit 11a, a reception unit 11b, a playback control unit 11c, a questionnaire execution unit 11d, an evaluation unit 11e, a learning unit 11f, and a main control unit 11g.

[0028] In this configuration, the transmission unit 11a transmits video data, questionnaire display data, etc. to the terminal device 2. The reception unit 11b receives questionnaire response data, etc. from the terminal device 2.

[0029] The playback control unit 11c controls the selection and distribution of videos to be promoted on the terminal device 2. More specifically, it first promotes playback of the target video by distributing video data of a common target video, and after the first target video is played, it promotes playback of the target video by distributing video data of a target video determined based on questionnaire response data described below, and then it sequentially distributes video data determined based on questionnaire response data, and finally it promotes playback of the suggested video by distributing video data determined by evaluation by the evaluation unit 11e described below. The playback control unit 11c stores and updates the played target video, information on the suggested video, and comment information sent from the terminal device 2 during playback in the evaluation storage unit 17 as needed (FIG. 5).

[0030] After the challenge video selected by the playback control unit 11c is played, the survey execution unit 11d identifies a survey associated with the played challenge video, transmits the survey data as display data to the terminal device 2 via the transmission unit 11a, and executes the survey. Then, the survey responses from the terminal device 2 are received via the reception unit 11b and stored in the evaluation storage unit 17 (FIG. 5).

[0031] The evaluation unit 11e selects suggested videos based on a scenario constructed by playing the challenge videos. More specifically, the evaluation unit 11e refers to the evaluation table stored in the evaluation storage unit 17, and for the selected and played challenge videos, refers to the table (FIG. 4(a)) stored in the video information storage unit 15 to identify the assigned points, records the assigned points in the evaluation table, and refers to the table (FIG. 4(b)) to identify suggested videos that meet the selection criteria based on the assigned points.

[0032] After a large amount of information has been accumulated in the evaluation memory unit 17, the learning unit 11f performs machine learning using the information in the evaluation memory unit 17 as learning data, constructs a mathematical model for selecting suggested videos, and stores the model in the evaluation memory unit 17. More specifically, the learning unit 11f performs machine learning using at least one of the following as learning data: information on the selected and played challenge video, the value of the awarded points, survey results, comments made while watching the video, and information on whether or not the video ultimately led to customer attraction, and constructs a mathematical model for selecting suggested videos. After this learning, the evaluation unit 11e can input identification information of the selected and played challenge video into the mathematical model of the evaluation memory unit 17 to select suggested videos.

[0033] In addition to the above, the main control unit 11g is in charge of overall control.

[0034] FIG. 3 shows the configuration of a terminal device in a video viewing system according to an embodiment of the present invention, and will be described below.

[0035] As shown in the figure, the terminal device 2 has a control unit 21, a communication I / F 22, a display unit 23, an operation input unit 24, an audio output unit 25, and a storage unit 26. The units 21 to 26 are connected to each other so as to be able to communicate with each other via a system bus. The communication I / F 22 is implemented by, for example, an NIC or the like, and is a communication interface that is connected to a communication network 3 such as the Internet by wire or wirelessly and communicates with the server device 1 or the like.

[0036] The display unit 23 is realized by a liquid crystal display or the like and displays various information. The display unit 23 can also be a projector or an external large display. The operation input unit 24 is realized by a mouse, keyboard, or the like and accepts various operation inputs from the user.

[0037] The audio output unit 25 is configured with a speaker, etc. The storage unit 26 is realized by, for example, a semiconductor memory element such as a RAM or a flash memory, an HDD, an optical disk device, etc., and stores the program executed by the control unit 21.

[0038] The control unit 21 is realized by a CPU, an MPU, etc., and may be configured as an integrated circuit such as an ASIC, an FPGA, etc. The control unit 21 reads and executes programs stored in the storage unit 26, thereby functioning as a transmission unit 21a, a reception unit 21b, an output control unit 21c, and a main control unit 21d.

[0039] In this configuration, the main control unit 21a is responsible for overall control of the terminal device 2. The transmission unit 21a transmits questionnaire response information and the like to the server device 1. The reception unit 21b receives video data, questionnaire display data, and the like. Then, the output control unit 21c controls the display by the display unit 23 and the audio output by the audio output unit 25 based on the received video data.

[0040] The processing procedure for video viewing by the video viewing system will be described in detail below with reference to the flowchart in Fig. 6. Here, the description will proceed with appropriate reference to the conceptual diagram in Fig. 7.

[0041] When this process starts, a menu screen is displayed on the display unit 23 of the terminal device 2 under the control of the output control unit 21c (S1). This menu screen introduces seminar videos of various categories. When a seminar video that the user wishes to view is selected by operating the operation input unit 24 of the terminal device 2, the transmission unit 21a transmits identification information of the selected seminar video to the server device 1 (S2).

[0042] In the server device 1, the receiving unit 11b receives the identification information of the seminar video sent from the terminal device 2 (S3), and the playback control unit 11c refers to the video information storage unit 15 to select the video to be first encouraged to be viewed, and transmits the video data to the terminal device 2 via the transmitting unit 11a (S4).

[0043] In the terminal device 2, the receiving unit 21b receives the video data, and under the control of the output control unit 21c, the video is played by the display unit 23 and the audio output unit 25 (S5). In this example, the challenge video K1 is played as shown in Fig. 7. Then, when the playback of the video is completed, a playback completion notice is sent to the server device 1 via the sending unit 21a under the control of the main control unit 21d (S6).

[0044] In the server device 1, the receiving unit 11b receives this playback completion notification (S7), and the survey execution unit 11c refers to the operation information storage unit 15 to identify the survey ID associated with the played video, refers to the survey information storage unit 16 to obtain the survey data corresponding to the survey ID, and transmits this as display data to the terminal device 2 via the transmitting unit 11a (S8).

[0045] In the terminal device 2, the receiving unit 21b receives the display data related to the questionnaire, and under the control of the output control unit 21c, a questionnaire screen is displayed on the display unit 23 (S9). In this example, the screen of questionnaire A1 is displayed as shown in FIG. 7. On this screen, answers can be selected from "A. I don't know how to operate it," "B. I can't attract customers," and "C. I can't negotiate." When an answer to the questionnaire is selected or entered by operating the operation input unit 24, the answer information is sent to the server device 1 via the sending unit 21a under the control of the main control unit 21d (S10).

[0046] In the server device 1, the receiving unit 11b receives the response information sent from the terminal device 2 (S11), and the playback control unit 11c refers to the survey information storage unit 16 to identify the video ID of the video corresponding to the survey response, refers to the video information storage unit 15 to select the video data corresponding to the video ID, and transmits the video data to the terminal device 2 via the transmitting unit 11a (S12).

[0047] In the terminal device 2, the receiving unit 21b receives the video data, and under the control of the output control unit 21c, the video is played by the display unit 23 and the audio output unit 25 (S13). In this example, as shown in Fig. 7, if option A is selected in the questionnaire A1, the assignment video K2 is played, if option B is selected, the assignment video K3 is played, and if option C is selected, the assignment video K4 is played. Then, when the video playback is completed, under the control of the main control unit 21d, a playback completion notification is sent to the server device 1 via the sending unit 21a (S14).

[0048] In the server device 1, the receiving unit 11b receives this playback completion notification (S15), and the survey execution unit 11c refers to the operation information storage unit 15 to identify the survey ID associated with the played video, refers to the survey information storage unit 16 to obtain the survey data corresponding to the survey ID, and transmits this as display data to the terminal device 2 via the transmitting unit 11a (S16).

[0049] In the terminal device 2, the receiving unit 21b receives the display data related to the questionnaire, and under the control of the output control unit 21c, a questionnaire screen is displayed on the display unit 23 (S17). In this example, as shown in FIG. 7, when the assignment video K2 is played, a questionnaire A2 screen is displayed; when the assignment video K3 is played, a questionnaire A3 screen is displayed; and when the assignment video K4 is played, a questionnaire A4 screen is displayed. In the questionnaires A2 and A4, answers can be selected from options A and B, which select the playback of other assignment videos, as well as option Z, which indicates that the user does not particularly wish to watch other assignment videos. In the questionnaires O and A3, options A to C can be selected to obtain more detailed information. When an answer to the questionnaire is selected or entered by operating the operation input unit 24, the answer information is transmitted to the server device 1 via the transmitting unit 21a under the control of the main control unit 21d (S18).

[0050] In the server device 1, the receiving unit 11b receives the answer information sent from the terminal device 2 (S19), and if the answer information indicates that viewing of another assignment video is desired, the process returns to step S12 and repeats the above process, and if viewing of another assignment video is not desired, the process proceeds to step S21.

[0051] Next, the evaluation unit 11e performs the evaluation (S21). That is, the evaluation unit 11e selects a suggested video based on a scenario constructed by playing the challenge video. Specifically, the evaluation unit 11e refers to the evaluation table stored in the evaluation storage unit 17, and for the selected and played challenge video, refers to the table (FIG. 4(a)) stored in the video information storage unit 15 to identify the assigned points, records the assigned points in the evaluation table, and refers to the table (FIG. 4(b)) to identify a suggested video that meets the selection criteria based on the assigned points.

[0052] After a large amount of information has been accumulated in the evaluation memory unit 17, the learning unit 11f performs machine learning using the information in the evaluation memory unit 17 as learning data, constructs a mathematical model for selecting suggested videos, and stores the model in the evaluation memory unit 17. More specifically, the learning unit 11f performs machine learning using at least one of the following as learning data: information on the selected and played challenge video, the value of the awarded points, survey results, comments made while watching the video, and information on whether or not the video ultimately led to customer attraction, and constructs a mathematical model for selecting suggested videos. After this learning, the evaluation unit 11e can input identification information of the selected and played challenge video into the mathematical model of the evaluation memory unit 17 to select suggested videos.

[0053] The server device 1 refers to the video information storage unit 15, selects video data corresponding to the video ID of the identified suggested video, and transmits the video data to the terminal device 2 via the transmission unit 11a (S22).

[0054] In the terminal device 2, the receiving unit 21b receives the video data, and under the control of the output control unit 21c, the video is played by the display unit 23 and the audio output unit 25 (S23). In this example, as shown in Fig. 7, one of the proposed videos T1 to T3 is played based on the result of the evaluation by the evaluation unit 11e. Then, when the playback of the video is completed, a playback completion notice is sent to the server device 1 via the sending unit 21a under the control of the main control unit 21d (S24).

[0055] In the server device 1, the receiving unit 11b receives this playback completion notification (S25), and the survey execution unit 11c refers to the operation information storage unit 15 to identify the survey ID associated with the played video, refers to the survey information storage unit 16 to obtain the survey data corresponding to the survey ID, and transmits this as display data to the terminal device 2 via the transmitting unit 11a (S26).

[0056] In the terminal device 2, the receiving unit 21b receives the display data related to the questionnaire, and under the control of the output control unit 21c, the questionnaire screen is displayed on the display unit 23 (S27). In this example, as shown in FIG. 7, the screen of the final questionnaire A10 is displayed. In the questionnaire A10, it is possible to input the desired date and time of the meeting. When an answer to the questionnaire is selected or input by operating the operation input unit 24, the answer information is transmitted to the server device 1 via the transmitting unit 21a under the control of the main control unit 21d (S28).

[0057] In the server device 1, the receiving unit 11b accepts the response information sent from the terminal device 2 (S29), and updates (registers) the evaluation data in the evaluation memory unit 17, including the success or failure of attracting customers (such as appointments) (S30), thus completing the series of processes.

[0058] As described above, according to an embodiment of the present invention, a server device is provided that distributes video data to a terminal device, and that includes a memory unit 13 that stores at least video data related to assignment videos and suggested videos, assigned points corresponding to the assignment videos, and selection criteria for the suggested videos, a transmitting unit 11a that transmits video data and questionnaire data to the terminal device, a receiving unit 11b that receives questionnaire response information, and a control unit 11 that distributes video data of common assignment videos to the terminal device, transmits questionnaire data to the terminal device to encourage completion of the questionnaire, receives questionnaire response information, selects the next assignment video based on the response information and transmits video data to the terminal device, calculates assigned points corresponding to the transmitted assignment video, evaluates the selection of a suggested video by comparing the assigned points with the selection criteria, and transmits video data of the suggested video to the terminal device based on the evaluation results, and controls the terminal device to transmit questionnaire data to complete the questionnaire and encourage an appointment. Here, the memory unit 13 stores historical information including the history of selection of the target video and the suggested video, the points awarded based on the selection, and the success or failure of the appointment, and further includes a learning unit 11f that performs machine learning using the historical information as learning data to construct a mathematical model for selecting suggested videos, and after learning, the control unit 11 selects suggested videos using the mathematical model.

[0059] Therefore, by selecting and playing a proposal video that is effective for appointments, and then conducting a questionnaire for appointments such as booking a meeting, it is possible to increase the effectiveness of attracting customers.

[0060] Although the embodiments of the present invention have been described above, it goes without saying that the present invention is not limited to these and that various improvements and modifications can be made without departing from the spirit of the present invention.
