At VisionaiR3D we believe the Virtual Reality is total immersion into a virtual (computer generated) environment through the use of image and sound,where you have total control over your movements and view in all directions and where you can manipulate objects and interact with your environment.

 

For something to be called Virtual Reality you need to fill these 3 criteria:

 

1. Immersion, making VR feel as real as possible, i.e.

    huge screen projection, 3D vision with or without head

    mounted displays (HMD's).

 

2. Navigation, You must be able to decide when and where

    you want to go in the virtual space.

 

3. Manipulation, You must be able to interact with objects

    in the virtual world.
