Enhancing User Immersion and Natural interaction in HMD based Virtual Environments with Real Time Visual Body Feedback using Multiple Microsoft Kinects

This paper presents an augmented VR system that provides real time visual body feedback with the help of multiple Microsoft Kinects. The advent of Microsoft Kinect provided the research community with an inexpensive but an extremely invaluable piece of equipment that can be used to obtain real time 3D information of the scene. We use this information to let users see their own self-representations in virtual environments. We also introduce in this paper, an IR-based position tracking system implemented using just the Kinects. We present here an analysis of the jitter and range of such a tracking system and the effects of interference on its performance for a common VR lab setup.
