Information processing device with an acceleration sensor

Abstract

The operating state of a computer is switched only when moving of the computer is detected. An information processing device has a detection unit, which detects, as a lifting action, a fact that an accelerated velocity has been kept applied in one direction for a given period of time, and a control unit, which executes a predetermined control operation that is associated with the lifting action detected by the detection unit. A lifting action detecting method has a detection step of detecting, as a lifting action, the fact that an accelerated velocity has been kept applied in one direction for a given period of time, and a control step of executing a predetermined control operation that is associated with the lifting action detected in the detection step.
