Real-time free-viewpoint 3D video for wheelchair seating assessment: preliminary assessment for local and remote applications

摘要

Using video-conference-based telerehabilitation technology to provide valid wheelchair assessment results can be a difficult task for occupational therapists (OT) due to the necessity of working on a 3D task within a 2D video-based screen. New virtual reality (VR) technology could improve this process by providing a real-time, 3D representation of the client and their wheelchair that can be remotely manipulated by the rehabilitation specialist. This pilot study examined the potential of combining the Zaxel Virtual Viewpoint/spl trade/ System (ZaxelVV) with the TightVNC application sharing software as a mean to improve visualization during an online wheelchair assessment. Following evaluation by two OT's, the current system was found to be appropriate for assessing overall posture in the wheelchair and wheeling hand position while a series of recommendations were also made before such a system could be used clinically. We also discuss the advantages and potential of the 3D approach including the possibilities for 3D measurements as well as automated assessments by a virtual therapist.
