Concepts

Also known as V.R., artificial reality, and virtual environments.
Virtual reality creates simulated environments on a computer.
Virtual reality uses hardware and software:
1. Headgear (Eyephone) - has earphones and 3-D stereoscopic screens.
2. Gloves (DataGlove) - have sensors that collect data about hand movement.
3. Software (Body Electric) - interactive sensory to immerse into computer-generated world.
VRML is a programming language to produce virtual reality applications.
Virtual reality authoring programs are use to create applications.

Virtual Reality Programming Language (VRML)

Used to create real-time animated 3-D scenes.
Can be used with browsers on the Internet.
Hundreds of sites exists on the Web with virtual reality applications.

Virtual Reality Authoring Programs

Several lower-cost and powerful authoring programs are available.
They use VRML and are widely used to Web-based virtual reality applications.
Examples:

Virtual Reality Applications

Ultimate recreational use - giant virtual reality amusement park.
Training and hazardous environments:
1. Flying simulation
2. Surgical operations
3. Spaceship repair
4. Nuclear disaster cleanup
