Virtual reality
systems were introduced to :the general public by
VPL and by AutoDesk on June 6, 1989, VR Day, at two trade shows.
This event was preceded by about four months of media coverage.
Since then, VR has captured the public's imagination. It is also in
The unique position of being commercially available before being
Academically understood.
VR is the body of techniques that apply computation to the generation
Of experientially valid realities

To give you an idea of what work and play will be like in VR, I'll describe some of the tools we're designing at HITL:
The wand
The virtual body
Virtual home, virtual community
Concurrent inconsistent worlds
Autonomous entities
Concrete mathematics, experiential programming
