ELECTRICAL DEVICE, CONTROL METHOD, AND PROGRAM

摘要

An acceleration sensor (3) detects acceleration. A timer (6) measures time. A calculation means (12) calculates jerk (J) of a remote controller (1) on the basis of the acceleration detected by the acceleration sensor (3). A factor judgment means (13) judges whether or not a user holds the remote controller (1) in his/her hand, on the basis of the transitory condition of the jerk (J) obtained from the index value calculated by the calculation means (12) and the time measured by the timer (6). A sleep control means (14) turns ON the display of a display unit (5) when the factor judgment means (13) judges that the user holds the remote controller (1) in his/her hand.
