WHAT IS IMMERSIVE VR?
Atype ofVR in which the user becomes immersed (deeply
involved) in a virtual world. it is also a form ofV
R that usescomputer related components.

Text-basedVR:when a reader of a certain text form a mental model of thisvirtual world in their head from the description of people , places andthings.
AugmentedVR:the idea of taking what is real and adding to it in some wayso that user obtains more information from their environment.

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

MEDICAL
The medical application ofVR was stimulated initially by the need ofmedical staff to visualize complex medical data, particularly duringsurgery and for surgery planning, and for medical education and training.

TRAINING
United States: The military used it as flight simulatorsto train pilots.
National Aeronautics and Space Administration (NASA)use VR technology to construct a model of the HubbleSpace Telescope (HST) .in September, 199 ,approximately 100 members of the NASA HST flightteam received over 200 hours of training using the

DEVICES
Head Mounted Displays (
HMD):
was the first device providing itswearer with an immersiveexperience. Evans and Sutherlanddemonstrated a head-mounted
stereo display already in 1965.

VIRTUAL REALITY MODELING LANGUAGE
(VRML)
Most exciting is the ongoing development ofVRML on theWorld Wide Web. In addition to HTML (Hypertext MarkupLanguage), that has become a standard authoring tool forthe creation of home pages, VRML provides three-
dimensional worlds with integrated hyperlinks on the Web.Home pages become home spaces.

FUTURE
1999 10% of the world's computing power was non-human
2029 99% of the worlds computing capacitywill be non-human
In the past, computing power has doubledapproximately every 18 months, a trend that is known asMoores Law. If this is the case then we should have a
computer powerful enough to run immersive VRprograms in our own homes by the year 20 7.
