VirtuSphere Immersive Virtual Reality
VirtuSphere provides a mechnical basis for truly immersive virtual reality environments, permitting the user to move about in virtual space by simply walking.
The device consists of a large hollow sphere which is mounted on a specially designed platform that allows the sphere to rotate freely as the user walks in any direction. The user wears a head-mounted display, which provides the virtual environment. Sensors under the sphere provide subject speed and direction to the computer running the simulation. Users can even ineract with objects in virtual space using a special manipulator.
