New opportunities emerge when mixed reality environments are ­augmented with immersive displays and full body, real-time tracking. Such systems enable the creation of experiences where users “share space” with other virtual humans in the virtual environment. These systems can portray responsive 3D virtual humans that react to position, motion, and gesture. The tracking data can also be used in analyzing physical and social responses to virtual characters. Additionally, such systems can use tracking data to identify opportunities for altering a user’s perception of the environment. This is helpful in situations where redirection or reorientation of the user might be done to “stretch space,” i.e. imperceptibly rotating or changing the environment around the user, so that a straight-line walk becomes a curve, preventing the user from ever encountering the 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.
