feelto the visual illusion, and computer-controlled sounds and odors reinforce the virtual environment. Other VR systems, such as flight simulators, use larger displays and enclosed environments to create an illusion. Immersive VR systems can cause a form of motion sickness due to a mismatch experienced by the body between aspects of the virtual world and the real one. Less-complicated systems for personal computers manipulate an image of three-dimensional space on a computer screen. In a virtual network many users can be immersed in the same simulation, each perceiving it from a personal point of view. VR is used in some electronic games, in amusement-park attractions, in military exercises, and to simulate construction and architectural designs. Experimental and envisioned uses include education, industrial design, surgical training, and art.
