Abstract
A state detection device includes an acquisition part that acquires an acceleration detection value from an acceleration sensor, and a judgment part that judges a running state or a walking state based on the acceleration detection value. The judgment part detects as to whether a positive/negative sign of the acceleration detection value in a first axis reversed in a predetermined judgment period, determines the running state when the sign reverses, and determines the walking state when the sign does not reverse.
Claims16
A state detection device comprising:
- an acquisition part that acquires an acceleration detection value from an acceleration sensor;
- and
- a judgment part that judges a running state or a walking state based on the acceleration detection value,
- the judgment part detecting as to whether a positive/negative sign of the acceleration detection value in a first axis reversed in a predetermined judgment period,
- determining the running state when the sign reverses, and
- determining the walking state when the sign does not reverse.
A program that renders a computer to function as an acquisition part that acquires an acceleration detection value from an acceleration sensor, and a judgment part that judges a running state or a walking state based on the acceleration detection value,
- the judgment part detecting as to whether a positive/negative sign of the acceleration detection value in a first axis reversed in a predetermined judgment period,
- the judgment part judging the running state when the sign reversed, and judging the walking state when the sign did not reverse.
