ELECTRICAL DEVICE, CONTROL METHOD, AND PROGRAM

摘要

An acceleration sensor detects an acceleration. A timer measures elapsed time. A calculation means calculates jerk J of a remote controller on the basis of an acceleration detected by the acceleration sensor. A factor determination means determines whether a user is holding the remote controller 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 and an amount of time measured by the timer. A sleep control means turns on display of a display if the factor determination means determines that the user is holding the remote controller in his/her hand.
