Computer Created - Virtual Reality

Virtual Reality (VR) systems create computer-generated, interactive environments. These environments can simulate portions of the "real world" or novel, imagined "other worlds." The least complex VR systems consist of PC-based, 3-D simulations with user interaction by keyboard, mouse, or other standard interface device. Complex VR systems create full sensory, immersive environments by use of head-mounted displays, haptic interface gloves, and other apparatus. VR systems are used in training for:

• Hazardous Environments - Realistic, full sensory replication of hazardous environments can be experienced with no risk to the trainee. For example, VR is used for firefighter training and enables novice firemen to safely learn the procedures for searching burning buildings.
• Hazardous Tasks - The military uses immersive VR systems for a variety of hazardous task training such as parachuting, tank battles, weapons use, and building searches, as well as pilot training and air-to-air combat.
• Remote Environments - NASA uses immersive VR for astronaut training and simulated Mars and inter-planetary exploration.
• Complex Environments - NASA/FAA Virtual Reality Tower can simulate any airport Tower in the world. Computer-generated images create a realistic, 360° external view that simulates time-of-day, seasons, weather conditions, and the movement of up to 200 aircraft and ground vehicles.
