Sharing and Stretching Space with Full Body Tracking

New opportunities emerge when mixed reality environments are augmented with wide field of view displays and full body, realtime tracking. Such systems will allow users see a correctly tracked representation of themselves in the virtual environment, and allow users to “share space” with other virtual humans in the virtual environment. Furthermore, such systems will be able to use tracking data to identify opportunities when a user’s perception of the environment can be altered. This would be helpful in situations where redirection or reorientation of the user might be done to “stretch space,” i.e. imperceptibly rotating the environment around the user, so that a straight-line walk becomes a curve, preventing the user from ever encountering walls in the physical space. We believe that allowing users to co-inhabit virtual spaces with virtual humans and decoupling physical size constraints from these virtual spaces are two important building blocks for effective mixed reality training experiences.
