Answer to Question 1
Virtual reality systems use interactive graphics software and hardware to create the illusion of reality in cyberspace. The original applications were in gaming, but new uses in education, science, and business are being developed and have great promise. Virtual reality applications are being developed for the Web using a standard called Virtual Reality Modeling Language (VRML), which can organize multiple media types to put users in a simulated real-world environment. VRML is platform independent, operates over a desktop computer, and requires little bandwidth. DuPont's HyperPlant is an example of a business application. HyperPlant allows users to go through three-dimensional models as if they were physically walking through a plant, which reduces errors during the construction of manufacturing structures. Augmented reality systems combine a direct view of physical world with computer-generated imagery to enhance the perception of reality. AR has been used in sports broadcasts, image guided surgery, military training, and other fields.
