Title:
STATE DETECTION DEVICE, ELECTRONIC APPARATUS, MEASUREMENT SYSTEM AND PROGRAM
Document Type and Number:
Japanese Patent JP2013190370
Kind Code:
A
Abstract:

To provide a state detection device that performs acceleration measurement and can perform estimation of a moving speed or the like, and further to provide an electronic apparatus, a measurement system, a program or the like.

A state detection device 100 includes: an acquisition section for acquiring detected acceleration from an acceleration sensor 200; an angle information arithmetic section 120 for calculating angle information indicating an angle between a first acceleration vector indicating the detected acceleration obtained at first timing and a second acceleration vector indicating the detected acceleration obtained at second timing on the basis of the first acceleration vector and the second acceleration vector; and an information acquisition section 130 for acquiring motion state information on the basis of the angle information.
