Abstract
This study investigates if it is possible to avoid a virtual obstacle seen by a monocular head-mounted display (HMD) in an augmented reality (AR) living environment for the evaluation of motor function. The trajectory of a toe during obstacle avoidance was measured by optical motion capture. In four conditions consisting of an AR living environment or a real environment, movements to avoid obstacles were performed, and two points of toe clearance front (TCF) and toe clearance rear (TCR), the heights from the top of the obstacle to the toe tip, respectively, were evaluated. Obstacle heights were 2, 9, and 21 cm. The results verified that it was possible to avoid the virtual obstacle because both TCF and TCR were not less than 0 cm. In addition to TCF and TCR, the highest point of the toe tended to be higher as the living environment approached the AR living environment. Therefore, to verify the accuracy of the obstacle avoidance motion, the use of a binocular HMD is necessary as it offers a smaller effect on human perception of the obstacle and allows for the examination and an evaluation method that does not affect variations in gait.
