Virtual Reality Simulators

I thought one the most interesting things discussed in the reading was the use of virtual reality for things other than video games or as an escape from reality. On page 108, Zettl says, "One of the highly practical functions of virtual reality is that it can let us see things that are ordinarily hidden from our view." He goes on to give the example of virtual reality systems used by medical students to learn about the human body, or to practice medical procedures with no harmful effects to a real person. Zettl says, "a mistake in [virtual reality] operating procedures may cause an angry computer beep or, at most, a crash. But it will certainly not jeopardize anyone's life." Other examples of virtual reality simulators used for practice include, flight simulators, driving simulators and war/battle simulators.
