Abstract:
1. A mobile terminal having a functional operation control unit which locks operations of various functions of the mobile terminal if no operation is performed within a certain period of time set in advance, at a timing when the certain period of time has elapsed, and sets the functions to be in an unusable state, the mobile terminal comprising: an acceleration sensor, configured with three sensors, for measuring acceleration observed values of orthogonal, respective three axes and observing three states including an abnormal state, a left state, and a normally used state as being neither of them based on the acceleration observed values of the respective three axes; a state determination rule storing unit for classifying the used state of the mobile terminal into the three states including the abnormal state where an amount of change in acceleration of the mobile terminal is equal to or more than a threshold, the left state, and the normally used state as being neither of them, and storing a state determination rule which determines a corresponding relation between the respective states and observed values by the acceleration sensor; and a used state determination unit for determining the used state of the mobile terminal as one of the three states based on the state of the mobile terminal observed by the acceleration sensor and the rule stored in the state determination rule storing unit, wherein when the mobile terminal is determined as being in the normally used state by the used state determination unit, the functional operation control unit performs setting control of the operation of the various functions having been set to be usable to maintain the usable state continuously even when the certain period of time has elapsed.
