State of Virtual Reality

Center for Responsible Nanotechnology has a recent article that recalls a passage from Unbounding the Future (1991) which discusses virtual reality with sensory feedback

What do we have now for the state of the art in virtual reality?



We have a 100 million pixel virtual reality room
The 10 foot by 10 foot cube room has new equipment -- a Hewlett-Packard computer cluster featuring 96 graphics processing units, 24 Sony digital projectors, an eight-channel audio system and ultrasonic motion tracking technology.

Virtusphere is another interface system

Haptic gloves are getting quite advanced. A realistic touch interface must ideally be able to change 500 times per second or more. (The human visual system will be fooled by images that change 20 times per second.)

Haptic body suits have been under development for quite a while

Gesture recognition is being incorporated in many devices and is supplied to game system like the Nintendo Wii, Microsoft Xbox and Sony Playstation 2 and Sony Playstation 3.
