To Reach the Unreachable: Exploring the Potential of VR Hand Redirection for Upper Limb Rehabilitation
Proceedings of the CHI Conference on Human Factors in Computing Systems(2024)
摘要
Rehabilitation therapies are widely employed to assist people with motor
impairments in regaining control over their affected body parts. Nevertheless,
factors such as fatigue and low self-efficacy can hinder patient compliance
during extensive rehabilitation processes. Utilizing hand redirection in
virtual reality (VR) enables patients to accomplish seemingly more challenging
tasks, thereby bolstering their motivation and confidence. While previous
research has investigated user experience and hand redirection among
able-bodied people, its effects on motor-impaired people remain unexplored. In
this paper, we present a VR rehabilitation application that harnesses hand
redirection. Through a user study and semi-structured interviews, we examine
the impact of hand redirection on the rehabilitation experiences of people with
motor impairments and its potential to enhance their motivation for upper limb
rehabilitation. Our findings suggest that patients are not sensitive to hand
movement inconsistency, and the majority express interest in incorporating hand
redirection into future long-term VR rehabilitation programs.
