Visualizations for locomotor learning with real time feedback in VR

摘要

The use of real time visual feedback within a virtual reality (VR) environment has received support as a method for rehabilitation [Holden 2005; Fung et al. 2006] of mainly upper body movements in motor-compromised patients. However, research into practical applications offering guidance on how best to present visual feedback to the patient is limited, especially for activity intended to aid the restoration of mobility by walking [Wellner et al. 2008]. This study firstly introduces a paradigm for step training using rendered representations of a subject's foot positions in a simple VR stepping task; and secondly, compares the effects of viewpoint in enhancing locomotor learning for the development of methods for stroke rehabilitation and related applications using VR.
