LOCOMOTION ANALYSIS DEVICE, LOCOMOTION ANALYSIS SYSTEM, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a technology for generating speed and position waveforms from which components having no importance for walking evaluation have been removed sufficiently.SOLUTION: A locomotion analysis device includes: acceleration waveform generation means for generating an acceleration waveform showing acceleration at each time, on the basis of data that has been obtained using an acceleration sensor and shows acceleration during a person's locomotion; speed waveform generation means for generating a speed waveform showing speed at each time, on the basis of the acceleration waveform; and position waveform generation means for generating a position waveform showing a position at each time, on the basis of the speed waveform. The position waveform generation means executes a plurality of pieces of first processing including first processing of calculating a position waveform by performing time-integration of the speed waveform and second processing of removing a component obtained by executing moving average processing on the position waveform from the position waveform; and generates a position waveform from which the component has been removed.SELECTED DRAWING: Figure 19
