STATE DETECTING DEVICE, ELECTRONIC APPARATUS, PROGRAM AND STATE DETECTING METHOD

A state detecting device includes an acquisition unit which acquires an x-axis component, a y-axis component and a z-axis component of an acceleration signal from an acceleration sensor, and an arithmetic unit which performs arithmetic processing. The arithmetic unit calculates a coordinate transformation matrix for finding an acceleration component in horizontal direction, from an average value of the x-axis component, an average value of the y-axis component and an average value of the z-axis component acquired by the acquisition unit, and discriminates between a first state where a person is in a first type of vehicle and a second state where the person is in a second type of vehicle that is different from the first type, based on the coordinate transformation matrix that is calculated and a first indicator value obtained from the x-axis component, the y-axis component and the z-axis component.
