We are progressively repositioning from a real world into a
virtual world. Or perhaps more accurately, we occupy more of our real world
time with virtual realities.
Our use of the term 'virtual' is no
longer a simple concept. The weather report is that rain is a virtual certainty
today. That is, rain is in effect but not in fact. It's close but not quite. Virtual,
pronounce it ˈver-chew-el', means almost as described but not completely;
very close to being something without actually being it. The term 'virtual' is used virtually all of the time, which is to say,
it's used nearly but not quite, or frequently but not always, although it seems
so. The term virtual is complex now, and
science and technology as pushed its boundaries. The adjective can also
intimate artificial, imitation, even make-believe.
Virtual reality or realities (VR) may be computer or
multimedia simulated replications of an imagined world or a real world which
allow users to interact with sensory experiences such as sight, touch, hearing
and smell.
