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. (Note that the open hatch in the picture above is closed during use.) 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.

Many applications for the VirtuSphere are foreseen:

Military, Law Enforcement, Dangerous Occupations training, simulationsVideo/LAN arcadesHealth and exercise, professional athlete training, fitness clubsBusiness and personal communicationsEducationVirtual travel and tourismVirtual museum exhibitsEntertainment at eventsHome gaming and exerciseThe ability to move physically and thereby control the simulation is one of the enabling technologies behind such science fictional devices as the Star Trek holodeck. The holodeck is a virtual environment that provides infinitely varied participatory, interactive entertainment in a very small space. On Federation starships, stressed crewmembers need to have some sort of outlet for exercise and entertainment.
