Abstract

Traditional methods of movement assessment in clinical rehab are often labor intensive and provide a limited number of outcome variables for tracking recovery. Entry level virtual reality (VR) systems afford new possibilities for systematic assessment and treatment. This paper describes the development of a virtual tabletop environment for the assessment of upper limb function in Traumatic Brain Injury (TBI). The system is designed to present realistic virtual workspaces and to measure performance at both a functional and kinematic level. In addition, we incorporate the use of Tangible User Interfaces (TUIs) as a means of integrating performance with the workspace. Unlike top-end movement analysis systems, the experimental system utilizes readily available computing technologies: mid-range PC, LCD panels, stereo camera, Virtools software, and TUI enabled by Wii Remote, Wii Sensor Bar (Nintendo™) and passive markers. The combination of vision-based marker tracking with a low cost game controller (viz Wii system) provides a stable and accurate means of tracking the TUI on the virtual workspace, and for interactivity within this space. The system provides a compelling sense of realism for the performer and an innovative means of assessing movement capabilities over time.
