Virtual Reality Immersion Environments

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 experiences:

1. The virtual world is presented in full scale and relates properly to the human size.
2. 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.
3. Stereoscopic viewing enhances the perception of depth and the sense of space.
4. Realistic interactions with virtual objects via data glove and similar devices allow for manipulation, operation, and control of virtual worlds.
5. The convincing illusion of being fully immersed in an artificial world can be enhanced by auditory, haptic, and other non-visual technologies.
6. Networked applications allow for shared virtual environments (see below).

Virtusphere

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. [1:15]

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 Display, respectively.

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.
