Document Type and Number:
WIPO Patent Application WO/2018/051540
Kind Code:
A1
Abstract:
[Problem] To provide a movement measurement device which can accurately measure the movement distance of a subject regardless of the radio environment. [Solution] This movement measurement device is provided with an acceleration sensor which is worn on one foot of the subject, a first state detection unit which detects the ground contact state of one foot, a distance calculation unit which calculates the movement distance of the subject on the basis of the detection result of the acceleration sensor, and a correction unit which corrects the position of the subject in the period in which the first state detection unit has detected that a foot is contacting the ground. The distance calculation unit calculates the movement distance from the position corrected by the correction unit.
