An Attempt to Visualize the Gait of Older Adults Requiring Care Using AI

― Data Collection in Scene of Daily Living ―

Abstract

  This study aims to propose a measurement system that can be utilized in caregiving settings while ensuring accurate data collection and to report on its usage experience. An experiment was conducted with two community-dwelling older adults, assuming application in caregiving environments. The measurement system comprised three smartphones (iPhone, Apple Inc.), a laptop, a markerless motion capture system (OpenCap), and an inertial sensor (ORPHE CORE, Orphe Inc.). Data collected using OpenCap were analyzed with the musculoskeletal modeling software ANYBODY (Terrabyte Inc.) to assess muscular and joint loads. By combining these measurement devices, the study established a system suitable for use in caregiving settings while ensuring measurement accuracy. The proposed gait measurement method using these two devices was found to be simple, time-efficient, and practical for application in caregiving environments.
