  A process in which the instant message application 113 automatically updates the presence information will be described in detail with reference to FIGS. FIG. 6 is a flowchart for explaining processing in which the instant message application 113 automatically updates presence information. Hereinafter, it is assumed that presence information is set to be communicable when the instant message application 113 is activated and a user logs in to the instant message service.

  In FIG. 6, the instant message application 113 determines whether or not the tablet PC 10a is placed with the display surface facing downward based on the detection result of the acceleration sensor 17 (step S1). When the tablet PC 10a is placed with the display surface facing downward (“Yes” in step S1), the instant message application 113 notifies the other terminal device of the absence via the server 20 (step S4). For example, when the user does not want to exchange messages, the user can notify the absence by placing the display surface of the tablet PC 10a downward.

  When the tablet PC 10a is not placed with the display surface facing downward (“No” in step S1), the instant message application 113 determines that the cover 41 of the tablet PC case 40 is based on the detection result of the LID sensor 19. It is determined whether or not it has been closed (step S2). When the cover 41 of the tablet PC case 40 is closed (“Yes” in step S2). The instant message application 113 notifies the absence to the other party's terminal device via the server 20 (step S4). For example, when the user does not want to exchange a message, the absence of the user can be notified by closing the cover 41 of the tablet PC case 40.

  When the cover 41 of the tablet PC case 40 is not closed (“No” in step S2), the instant message application 113 determines whether or not the surrounding is dark based on the detection result of the ALS sensor 19. (Step S3). For example, the instant message application 113 can determine that the surrounding is dark when the brightness detected by the ALS sensor 19 is equal to or less than a threshold value. If the surroundings are dark (“Yes” in step S3). The instant message application 113 notifies the absence to the other party's terminal device via the server 20 (step S4). For example, the user can notify the absence when the tablet PC 10a is placed in a bag or a desk. In this way, when it is desirable to set absence, absence can be set automatically without the user manually setting absence.

  With reference to FIG. 7, an example of a display screen displayed by the instant message application 113 will be described. In particular, FIG. 7 is displayed on the tablet PC 10a of the user A and the other terminal device 10 of the user B when the instant message service is used between the tablet PC 10a of the user A and the other terminal device 10 of the user B. It is a figure for demonstrating an example of a screen.

  In FIG. 7, 301 is a screen displayed on the tablet PC 10a of the user A, 302 is the user name and presence information of the user A and the communication partner (user B), and 303 is the user A and the communication partner (user B). An area in which a transmitted (written) message is displayed is shown. 401 is a screen displayed on the terminal device 10b of the user B, 402 is the user name and presence information of the user B and the communication partner (user A), and 403 is transmitted by the user B and the communication partner (user A). Shows the area where the message is displayed.

  As described above, the presence information received from the partner via the server 20 is displayed on the screen on the tablet PC 10a and the other terminal device 10 so that the presence information of the partner can be known. From this presence information, it is possible to know whether or not the other party can exchange messages. The transmitted message is immediately displayed on the other party's screen via the server 20, and real-time message exchange can be performed.

  When the user A puts the tablet PC 10a with the display surface facing downward, puts it in a dark place (for example, in a desk, in a bag, etc.) or closes the cover 41 of the tablet PC case 40 The tablet PC 10 a transmits “absence” as presence information to the other terminal device 10 via the server 20, and “absence” of the user A is displayed on the other terminal device 10. Thereby, the user B can know that the user A is not in a state where messages can be exchanged.

  When the terminal device 10 is a smartphone, the presence information may be changed to “absent” only when the smartphone is placed with the display surface facing downward. In the case of a smartphone, since the user usually keeps it at hand and always uses it, it is considered desirable to be “absent” only when the smartphone is placed with the display surface facing down at the user's will.

  In the example shown in FIGS. 6 and 7, “absence” is set as the presence information when the tablet PC 10 a is placed with the display surface facing downward. However, even if “absent” is set, a message may be sent from the other party. Therefore, when the tablet PC 10a is placed with the display surface facing downward in consideration of not receiving any message, presence information is provided. “Reject incoming call” may be set.

  8 and 9 are diagrams for explaining another example of processing in which the instant message application 113 automatically updates presence information with reference to FIG. 8 and FIG. 9. FIG. 8 is a flowchart for explaining another example of the process in which the instant message application 113 automatically updates the presence information.

  In FIG. 8, the instant message application 113 determines whether or not the tablet PC 10a is placed with the display surface facing downward based on the detection result of the acceleration sensor 17 (step S1). When the tablet PC 10a is placed with the display surface facing downward (“Yes” in step S1), the instant message application 113 notifies the other terminal device of “reject call” via the server 20 (step S1). S5). As a result, as described above, since the message is not transmitted from the server 20 to the terminal device for which “incoming call rejection” is set as the presence information, the user A places the tablet PC 10a with the display surface facing downward. Does not need to receive messages from the other party.

  FIG. 9 shows a screen displayed on the tablet PC 10a of the user A and the other terminal device 10 of the user B when the instant message service is used between the tablet PC 10a of the user A and the other terminal device 10 of the user B. It is a figure for demonstrating the other example of. In FIG. 9, the description of the parts common to FIG. 7 is omitted.

  When the user A places the tablet PC 10a in a dark place (for example, in a desk or in a bag) or closes the cover 41 of the tablet PC case 40, the tablet PC 10a displays “ “Absence” is transmitted to the other terminal device 10 via the server 20, and “absence” of the user A is displayed on the other terminal device 10.

  When the user A places the tablet PC 10a with the display surface facing downward, the tablet PC 10a transmits “reject call” as presence information to the other terminal device 10 via the server 20, and the other On the terminal device 10, the “call rejection” of the user A is displayed.

  As described above, according to the present embodiment, the presence of the acceleration sensor 17 for detecting the posture of the tablet PC 10a and the detection result of the acceleration sensor 17 is changed and the presence information is changed and notified to the counterpart terminal. Therefore, it is possible to easily change the presence information reflecting the user's intention.

  In addition, when it is detected that the front surface of the tablet PC 10a is placed downward, the presence information is changed to “absent”, and therefore the user places the front surface of the tablet PC 10a downward. It is possible to notify the other party of “absence”.

  In addition, when it is detected that the front surface of the tablet PC 10a is placed downward, the presence information is changed to “reject incoming call”, so the user places the front surface of the tablet PC 10a downward. In this case, it is possible to notify the other party of “call rejection”.

  In addition, an LID sensor 19 for detecting opening / closing of the cover 41 of the tablet PC case 40 with respect to the front surface of the tablet PC 10a is provided. When the closed state of the cover 41 with respect to the front surface of the tablet PC 10a is detected, presence information Therefore, when the user closes the cover 41 of the tablet PC case 40, it is possible to notify the other party of “absence”.

  In addition, since the ALS sensor 18 for detecting the brightness around the tablet PC 10a is provided and the presence information is changed to “absent” when it is detected that the tablet PC 10a is dark, the user can change the presence information to the tablet PC 10a.
