INFORMATION PROCESSING DEVICE, WALKING ENVIRONMENT DETERMINATION DEVICE, WALKING ENVIRONMENT DETERMINATION SYSTEM, INFORMATION PROCESSING METHOD, AND MEMORY MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/240753
Kind Code:
A1
Abstract:
Provided is an information processing device comprising: an acquisition unit that acquires load information based on a load applied to a load measurement device from the sole of a user; and a feature quantity extraction unit that extracts a feature quantity, which indicates a walking environment, from time-series data of at least one walking cycle contained in the load information.
