Virtual Reality can be experienced using VR
human interaction devices such as HMD, gloves, joysticks, wands
and mouse to a computer, or it can be a more immersive exeperience
using a CAVE environment.
Directional sound, tactile and force feedback devices, voice recognition
and other technologies are being employed to enrich the immersive
experience and to create more "sensualized" interfaces.
Using immersive virtual realisty presents a number of unique VR
The virtual world is presented in full scale and relates properly
to the human size.
Head-referenced viewing provides a natural interface for the
navigation in three-dimensional space and allows for look-around,
walk-around, and fly-through capabilities in virtual environments.
Stereoscopic viewing enhances the perception of depth and the
sense of space.
Realistic interactions with virtual objects via data glove and
similar devices allow for manipulation, operation, and control
of virtual worlds.
The convincing illusion of being fully immersed in an artificial
world can be enhanced by auditory, haptic, and other non-visual
Networked applications allow for shared virtual environments

The Virtusphere is a large hollow sphere which sits on a set of
computer monitored wheels. This allows the sphere to rotate a complete
360º whilst still allowing the computer to track the movments.
Multi-VR Networked Users
Networked users at different locations can meet in the same virtual
world by using a BOOM device, a CAVE system, and a Head-Mounted
All users see the same virtual environment from their respective
points of view.
Each user is presented as a virtual human [Avatar] to the other
participants. The users can see each other, communicated with each
other, and interact with the virtual world as a team.
