Virtual Reality existed long before it was classified as "virtual reality" in the way that the public now perceives it. Many simulation programs used the basic ideas of a theoretical environment and its resulting behaviors to stimuli. Like many areas of current technology, VR has strong roots in the military. It was and still is used for education and training for military situations, much like the medical industry uses virtual reality

Another area of interest is the mapping of the human body. The development of the virtual human body through the actual imaging of a cadaver has led to new and exciting modeling of biological systems. Doctors can get a 3-D view of any selected area of the body. For example, one can view the arrangement of the blood vessels in the leg and see how they interact. They can use this information, when they have to surgically manipulate this area, to know the layout of the vessels.

For the first few years of its development, virtual reality was used to help with hypothetical situations involving spatial relations and flight simulators. It allowed virtual tours of buildings and environments. The push for medical applications arose from the huge advantage that a surgeon or doctor has if he or she has already "seen" the situation. It eliminated many cases of exploratory surgery in which the doctor had to actually open up the person to see what was wrong. After many successes, the field of medical virtual reality grew and grew.
