The voice input by 35 is converted into voice data and transmitted to the teacher terminal 3 by the communication unit 26.
The teacher terminal 3 displays an image based on the image data received from the digital signage device 1 on the display unit, and causes the audio output unit to output sound based on the audio data received from the digital signage device 1.

  When the English conversation learning service is started, the control unit 23 determines whether or not it has been detected that the topic is exhausted and the silence state is reached (step S123). For example, when the state in which the sound pressure of the sound signal input from the sound input unit 35 is equal to or lower than a predetermined threshold continues for a predetermined time, the control unit 23 determines that it has detected that the silence state has been reached.

  When it is determined that it has been detected that the topic is exhausted and the silence state is detected (step S123; YES), the control unit 23 displays an inquiry screen as to whether or not to output related content related to the advertisement content viewed by the user. The image is displayed on the image forming unit 27 (step S124).

  When an operation button corresponding to “output related content related to advertisement content” is pressed by the operation unit 32 and it is selected to output related content (step S125; YES), the control unit 23 stores the memory The related content related to the advertisement content viewed by the user is output by the image forming unit 27 and the audio output unit 34 with reference to the advertisement content viewing history of the user stored in the predetermined area (step S126).

  Specifically, the content data associated with the content ID stored as the advertisement content viewing history of the user in a predetermined area of the memory is read from the advertisement related information storage unit 253, and the image forming unit 27 and the audio output unit 34 to output. The related content may be the advertising content itself viewed by the user before, or may be information related to a product advertised with the advertising content previously viewed by the user. For example, when the advertisement content viewed by the user is an advertisement related to a camera, it is possible to display advantageous information related to the camera, such as “XX camera, 2 discounts only today!”.

  When the output of the related content ends, the control unit 23 adds a predetermined number of points to the point information stored in the predetermined area of the memory (step S127), and proceeds to step S128.

  On the other hand, in step S125, when the operation button corresponding to “Do not output related content related to advertisement content” is pressed by the operation unit 32 and it is selected not to output related content (step S125; NO), control is performed. The unit 23 proceeds to step S128.

  In step S128, the control unit 23 determines whether or not the attendance time has elapsed (step S128). When it is determined that the attendance time has not elapsed (step S128; NO), the control unit 23 returns to step S123.

  If it is determined in step S128 that the attendance time has elapsed (step S128; YES), the control unit 23 subtracts the number of points corresponding to the attendance of the English conversation learning service from the point information stored in the predetermined area of the memory. (Step S129). And the control part 23 cut | disconnects communication with the teacher terminal 3 by the communication part 26, complete | finishes an English conversation learning service (step S130), and transfers to step S13 of FIG.

  In step S13 of FIG. 4, the control unit 23 records the advertisement content viewing history and point information stored in the predetermined area of the memory on the IC card 4 by the non-contact communication unit 33 (step S13), and clears the memory. Log out (step S14) and return to step S1.

  The control unit 23 repeatedly executes the processes of steps S1 to S14 until the power of the digital signage device 1 is turned off.
