Enhancing Presence in Head-Mounted Display Environments by Visual Body Feedback Using Head-Mounted Cameras

—A fully-articulated visual representation of a user in an immersive virtual environment (IVE) can enhance the user’s subjective sense of feeling present in the virtual world. Usually this requires the user to wear a full-body motion capture suit to track real-world body movements and to map them to a virtual body model. In this paper we present an augmented virtuality approach that allows to incorporate a realistic view of oneself in virtual environments using cameras attached to head mounted displays. The described system can easily be integrated into typical virtual reality setups. Egocentric camera images captured by a video-see-through system are segmented in real-time into foreground, showing parts of the user’s body, e. g., her hands or feet, and background. The segmented foreground is then displayed as inset in the user’s current view of the virtual world. Thus the user is able to see her physical body in an arbitrary virtual world, including individual characteristics ...
