Virtual reality (VR) – the computer-generated simulation of a real or imagined physical space – is probably the ultimate multimedia experience because it immerses you in a completely artificial environment. VR environments typically produce one of three possible image types: Simulations of Real Places. You might find yourself in a virtual room, car, or cave. Simulations of Imaginary Places. In this kind of simulation, you could be riding alongside King Arthur or battling aliens. Simulations of Real Things That Do Not Exist. In this kind of simulation, you could walk through a building that has not been built yet. Uses for Virtual RealityPeople use these VR simulations in many situations: Training. VR simulations of air combat, space shuttle flights, or nuclear reactor meltdowns provide excellent low-cost training areas. Document and Facilities Management. Virtual reality allows you to file electronic documents visually. Using such a system, you can create a virtual model of a factory and then attach maintenance records to each item within the factory. Design. By building a prototype in VR, a designer can work out design and construction flaws before the product leaves the drawing board. Entertainment. VR games and adventures are the ultimate fantasy experience. VR Hardware and SoftwareVR technology appears in the following formats: On-Screen. Images are displayed on a computer screen. The user is outside the environment, which limits the "reality" effect. There are many different head-mounted VR displays. Using such a device, the wearer feels immersed in the virtual environment, without distractions from outside. Head-Mounted Displays. Developers have created helmets and goggles that display stereoscopic images close to the user's eyes. The images block the outside world and create the illusion of a world that wraps around the wearer. As the wearer turns his or her head, tracking devices tell the computer to change the image, allowing the wearer to look around the virtual environment rather than stare straight ahead. Rooms. These rooms, called Cave Automatic Virtual Environments (CAVEs), contain complex projection and stereo equipment that create a complete virtual world. The user can move around the room and move objects with the aid of a wand. Clothing. Developers are working on VR clothing, like chest pads and gloves, that provide tactile feedback when you touch a virtual object. The most impressive VR equipment costs hundreds of thousands of dollars. Nevertheless, home users can experience convincing VR using low-end equipment and a home PC. жүктеу/скачать 0,7 Mb.
