Virtual Reality  (textbook definition)

 a medium composed of interactive computer simulations that 

sense the participant's position and actions and replace or 

augment the feedback to one or more senses, giving the feeling

of being mentally immersed or present in the simulation (a

virtual world).

The Ultimate Display -

   The ultimate display would be a room within which the

computer can control the existence of matter. Such a display

could literally be the Wonderland into which Alice walked.

Cyberspace: a location that exists only in the minds of the 

participants, often as a result of technology that enables

geographically distant people to interactively communicate.

Augmented Reality: a type of virtual reality in which synthetic 

stimuli are registered with and superimposed on real-world objects;

often used to make information otherwise imperceptible to human

senses perceptible.
