Projection Based VR
Projection-based virtual reality displays, such as the CAVE,
display 3D images
on video projection screens or monitors; users wear lightweight
stereo glasses to view them. This is an alternative to the more
traditional approach of HMDs or BOOMs, which use small video displays
that are coupled to the user's head.
