Virtual Reality/Environment Definition
The terms Virtual Reality (VR) and Virtual Environment (VE) was coined in the mid 1980s.
Around 1992 VR became the dominantly used expression in the non-research community, (Bryson, 1999). Bryson came up with the definition
"Virtual Reality is the use of computer technology to create the effect of an interactive three-dimensional world in which the objects have a sense of spatial presence."
Further stating (after putting the meanings of the words `virtual' and `reality' together) that
`Virtual Reality' means "to have the effect of having concrete existence without actually having concrete existence"
From Merriam-Webster's Collegiate Dictionary, http://www.m-w.com/
"Virtual Reality - Date 1989: an artificial environment which is experienced through sensory stimuli (as sights and sounds) provided by a computer and in which one's actions partially determine what happens in the environment",
