Abstract

This paper describes the development of an integrative system for gait rehabilitation. The system can present visual images and the sensation of walking to a user. The system consists of a locomotion interface, “GaitMaster4,” and a spherical immersive projection display. The locomotion interface moves the users’ feet while it keeps their bodies in the real world. Wide-angle images captured from an omnidirectional camera are projected onto the immersive projection display. To evaluate the system, subjects’ brain activity was measured using near infrared spectroscopy (NIRS), and the effectiveness of the system was confirmed.
