Abstract

A display control device (500) is the display control device (500) that controls output of display data to a plurality of display units that are arranged on different surfaces of a case, comprising a posture detection unit (510), a visibility state determination unit (520), and a display data output unit (530). The posture detection unit (510) detects a posture of the case. The visibility state determination unit (520) determines a display unit that is visually recognizable to the user from among the plurality of display units according to the posture of the case detected by the posture detection unit (510). The display data output unit (530) outputs the display data to the display unit that the visibility state determination unit (520) determined as visually recognizable to the user.

Claims

1. A display control device that controls output of display data to a plurality of display units that are arranged on different surfaces of a case, comprising:

a posture detection unit that detects a posture of the case;

a visibility state determination unit that determines a display unit that is visually recognizable to a user from among the plurality of display units according to the posture of the case detected by the posture detection unit;

a display data output unit that outputs the display data to the display unit that has been determined as visually recognizable to a user by the visibility state determination unit; and

a time determination unit that calculates elapsed time since the user started an action of taking the case in a hand and determines whether or not the calculated elapsed time is not less than a predetermined time, wherein, when the elapsed time is determined as not less than the predetermined time by the time determination unit, the display data output unit outputs the display data to the display unit that has been determined as visually recognizable to the user,

the display control device further comprising;

a contact detection unit that detects a contact between the case and a finger of a user; and

an acceleration detection unit that detects acceleration of the case, wherein, when the contact detection unit detects a contact between the case and a finger of a user, as well as, as a result of determining whether or not the acceleration detected by the acceleration detection unit is not less than a predetermined acceleration reference value, the acceleration is determined as not less than the reference value, the time determination unit determines that the user has started the action of taking the case in a hand and starts detecting the elapsed time.

2. The display control device according to claim 1, wherein the time determination unit determines that the user has not started the action of taking the case in a hand when the contact detection unit does not detect a contact between the case and a finger of the user or when the acceleration detected by the acceleration detection unit is less than the reference value, and the display data output unit does not output the display data to the display unit that is determined as visually recognizable to the user when the time determination unit determines that the user has not started the action of taking the case in a hand.
