Title:
A locomotive movement analysis device, a method, a system, and a program
Document Type and Number:
Japanese Patent JP6259301
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enable objective analysis of moving motion such as walking of a person.SOLUTION: There is provided a moving motion analysis apparatus comprising: feature quantity calculation means for calculating feature quantities on which are reflected acceleration components in horizontal and vertical directions at each time on the basis of the acceleration components of a person in horizontal and vertical directions at each time measured by acceleration sensors; binarization means for binarizing the feature quantities at each time calculated by the feature quantity calculation means, on the basis of the values of the feature quantities, to obtain binarized data at each time; variation calculation means for calculating the degree of variation for the binarized data in a predetermined time range at each time, the predetermined time range including the time; and determination means for determining the duration of moving motion in the time period in which the degree of variation exceeds a predetermined threshold value.
