Application of visual feedback and AR-enhanced wheelchair skill training.

Purpose: Manual wheelchair users with spinal cord injury (SCI) face challenges in wheelchair skill training (WSTr) due to the complexity of learning advanced skills and limited access to rehabilitation services. This review aims to summarize existing WSTr methods for individuals with SCI/disabilities and propose the use of Augmented Reality (AR)-enhanced Immediate Visual Feedback (ARe-IVF) learning modules for wheelie and curbing skill training.

Methods: The proposed ARe-IVF learning modules will incorporate AR-enhanced visual feedback, allowing users to visualize spatial and temporal aspects of wheelchair skills and assess their performance through computer vision technology. These modules are designed to tailor the learning experience to each user's SCI level, age, gender, body height, and weight. Key features of the ARe-IVF modules include verbal cues, computer graphic indications, and AR-enhanced feedback to support skill acquisition.

Results: The anticipated outcomes of the ARe-IVF modules include improved safety and effectiveness in WSTr by providing intuitive and concise guidance for key movements in wheelie and curbing maneuvers. Additionally, these modules offer an accessible alternative WSTr method for manual wheelchair users, caregivers, and rehabilitation therapists, with potential applications in Rehabilitation Centers, Hospitals, or home settings.

Conclusion: The ARe-IVF learning modules present an innovative approach to WSTr for manual wheelchair users with SCI, so that the modules provide promising learning outcomes through tailored, AR-supported feedback. This approach may empower wheelchair users to develop advanced skills with increased safety and confidence, ultimately improving rehabilitation outcomes and expanding training accessibility.
