Virtual Environment (VE)

A computer generated world with which the user can interact Interaction can vary from looking around to interactively modifying the world.

Classroom is a VE .

Definition What is virtual reality(VR)? A computer generated.multi-sensory information program which tracks a user in real time.immersive (or wide field). .

Types      Immersive Augmented Text-based Desktop (Window on a World) Video Mapping .

What is Immersive VR? A type of VR in which the user becomes immersed (deeply involved) in a virtual world. . it is also a form of VR that uses computer related components.

Types of Non-immersive VR   Text-based VR: when a reader of a certain text form a mental model of this virtual world in their head from the description of people . places and things. . Augmented VR: the idea of taking what is real and adding to it in some way so that user obtains more information from their environment.

Applications        Architecture Training Medicine Engineering and Design E-Commerce Entertainment Manufacturing .

Already being created are architectural "walkthroughs" that allow designers and clients to examine homes and office buildings. . before they're built. With virtual reality.Architecture An area in which virtual reality has tremendous potential is in architectural design. inside and out. designers can interactively test a building before construction begins.

particularly during surgery and for surgery planning. and for medical education and training.Medicine   researchers are using virtual reality technology to create 3-D ultrasound images to help doctors diagnose and treat congenital heart defects in children The medical application of VR was stimulated initially by the need of medical staff to visualise complex medical data. .

.Training   United States: The military used it as flight simulators to train pilots.in September. approximately 100 members of the NASA HST flight team received over 200 hours of training using the VR.. National Aeronautics and Space Administration (NASA) use VR technology to construct a model of the Hubble Space Telescope (HST) . 1993. .

Evans and Sutherland demonstrated a head-mounted stereo display already in 1965. .Devices Head Mounted Displays (HMD): was the first device providing its wearer with an immersive experience.

Screens and optical system are housed in a box that is attached to a multi-link arm. .Binocular Omni-Orientation Monitor (BOOM) BOOM is a head coupled stereoscopic display device.

Cave Automatic Virtual Environment (CAVE)    A room with projections on all walls. The users are able to move and control the environment with some kind of input mechanism   Camera Device in hand . floor and ceiling The users wear shutter glasses to get a 3D view of the world.

that has become a standard authoring tool for the creation of home pages. Home pages become home spaces. In addition to HTML (Hypertext Markup Language). VRML provides three-dimensional worlds with integrated hyperlinks on the Web.Virtual reality Modeling Language (VRML) Most exciting is the ongoing development of VRML on the World Wide Web. .

Characteristics Of VRML  Not a programming language like c++ or java Descriptive (rather than procedural) like HTML File formats contains human readable and editable ASCII text   .

If this is the case then we should have a computer powerful enough to run immersive VR programs in our own homes by the year 2037.Future 1999 10% of the world's computing power was non-human 2029 99% of the world’s computing capacity will be non-human In the past. computing power has doubled approximately every 18 months. a trend that is known as Moore’s Law. .
