ELECTRICAL DEVICE, CONTROL METHOD, AND PROGRAM

摘要

An acceleration sensor (3) detects an acceleration. A timer (6) measures elapsed time. A calculation means (12) calculates jerk J of a remote controller (1) on the basis of an acceleration detected by the acceleration sensor (3). A factor determination means (13) determines whether a user is holding the remote controller (1) in his/her hand on the basis of the change of the jerk J that is obtained from an index value calculated by the calculation means (12) and an amount of time measured by the timer (6). A sleep control means (14) turns on display of a display (5) if the factor determination means (13) determines that the user is holding the remote controller (1) in his/her hand.
