<P>PROBLEM TO BE SOLVED: To confirm locking by a portable apparatus. <P>SOLUTION: A control unit of the portable apparatus detects acceleration of its apparatus by an acceleration sensor (S1) and detects a sound by a microphone (S2). The control unit collates movement of its apparatus specified with the acceleration detected by the acceleration sensor with a movement pattern representing movement of a key for locking (S3). Then the control unit collates time-series change of the sound detected by the microphone with a sound pattern of a sound generated during the locking (S4). The control unit determines that the locking is performed when the movement and detected sound of its apparatus match the respective patterns in a certain period (S5: YES), and reports that to the user (S6, S7). When the user makes a lock, the movement according to the unique pattern is needed and the sound is generated during the locking, so the portable apparatus can detect whether the lock is made from the two events. <P>COPYRIGHT: (C)2012,JPO&INPIT |
