STATE DETECTOR, ELECTRONIC APPARATUS, MEASUREMENT SYSTEM, AND PROGRAM

Title:

STATE DETECTOR, ELECTRONIC APPARATUS, MEASUREMENT SYSTEM, AND PROGRAM

Document Type and Number:

Japanese Patent JP2013190371

Kind Code:

A

Abstract:

To provide: a state detector which properly determines a walking state and a running state on the basis of an acceleration value detected by an acceleration sensor; an electronic apparatus; a measurement system; and a program.

A state detector 100 includes an acquisition part 110 which acquires an acceleration value detected by an acceleration sensor 200 and a determination part 160 which determines a walking state and a running state on the basis of the detected acceleration value. The determination part 160 detects whether the positive-negative sign of the detected acceleration value in a first axis is inverted in a predetermined determination period. When the inversion of the positive-negative sign is detected, it is determined to be in a running state. When the inversion of the positive-negative sign is not detected, it is determined to be in a walking state.
