MOBILE TERMINAL, MOBILE TERMINAL STATUS DETERMINATION SYSTEM, PROGRAM, STORAGE MEDIUM AND MOBILE TERMINAL STATUS DETERMINATION METHOD

摘要

A portable terminal includes: an acceleration measuring unit that measures acceleration of the portable terminal; a calculating unit that calculates a first feature value for in-plane directions in which the portable terminal is in contact with an object and a second feature value for an out-of-plane direction on the basis on the acceleration measured by the acceleration measuring unit in a state in which the portable terminal is put on the object, when the portable terminal is vibrated; and a specifying unit that specifies a material of the object on the basis of the first feature value and the second feature value.
