Few Technologies in recent years have evoked such fiery discussions in the
technical community, and fewer still have sparked such passionate involvement of
the humanities and the cultural sector. --- Carl Machover.
VR: The quality of the experience is crucial. To stimulate creativity and
productivity, the virtual experience must be credible. The "reality" must
both react to the human participants in physically and perceptually appropriate
ways, and confirm to their personal cognitive representations of the microworld
in which they are engrossed. --- Carl Machover CG&A 1994.
