DefinitionWhat is Virtual Reality?

• Virtual reality is, plainly speaking, seeing an imaginary world, rather than the real one. Seeing, hearing, smelling, testing, feeling. The imaginary world is a simulation running in a computer. And the sense data is fed by some system to our brain.

• A medium composed of interactive computer simulations giving users the feeling of being present in the simulations.

Brief History Cinerama Widescreen film format (originally called

vitarama) invented in 1939 by Fred Waller and Ralph Walker. This system was used by The Army Air Corps for anti aircraft training.

In 1950s, Flight simulators were built by the US Air Force to train student pilots.

• Sesorama simulator was built by Morton Heilig in 1962. Simulation that contained Stereoscopic images, motion chair, audio, temperature changes, and blown air. One could see, hear, feel motion and smell during the simulation.

In 1988, commercial development of VR began.

In 1991, first commercial entertainment VR system "Virtuality" was released.

In 1992 a method of the showing and testing of scientific visualizations called the CAVE was created.

Types of VR Technology's Project Natal

Its a new piece of technology that developed for the Xbox 360. Project Natal proposes a new way of interacting with games, and indeed with computer systems in general. They propose that there system will not require any keyboards or controller. It will function by the use of the user's voice and motions as the method for interacting with the system.

Cave Automatic Virtual Environment• The term “CAVE" refers to any virtual reality system that

uses multiple walls with multiple projectors to immerse users in a virtual world. The CAVE is used for visualizing data, demonstrating 3D environments, and virtually testing component parts of newly developed engineering projects.

The Nintendo Wii

• The controller is basically a simplified version of the "virtual reality glove." Both the Wiimote and the Wii Fit offer users another way of interacting with their virtual environment without having to wear any bulky equipment.

Applications• Movies - Virtual reality is applied in 3-D movies to try and immerse

the viewer into the movie and/or virtual setting the environments.

• Video Games - Virtual reality is evident in video games. You can physically interact with a game by using your body and motions to control characters and other elements of the game that years ago people would only imagine.

• Education and training – Training and education is done through virtual reality because it can prepare you for many dangerous jobs and put the worker in real scenarios without the risk of them being hurt. Doing this enables them to fully train and educate themselves in almost any situation possible so that they’re ready and well equipped for the job. Virtual reality can give them the experience they need without actually putting them or others in danger.

Latest topics: Sixth sense device:

'Sixth Sense' is a wearable gestural interface that augments the physical world around us with digital information and lets us use natural hand gestures to interact with that information.

3D Animation Movie Making Process :

New technology that could finally revolutionize the film making by getting the 3D and the CGI(computer

graded imaginary) to new heights while mixing the real footage and the motion-captured CGI in an immersive 3D technology.

In Avatar, specifically used a novel technique called “image-based facial performance capture” that required actors to wear some special headgears already equipped with camera.

‘Mind-to-Mind' Communication in Humans:In August 2013, University of Washington scientists Rajesh Rao andAndrea Stocco succeeded in making human-to-human, brain-to-brain interface.

A computer converted Rao’s brain signals into a digital signal and beamed it to Stocco’s TMS helmet. That helmet converted the signal into a burst of magnetic stimulation delivered to the precise region of Stocco’s motor cortex that controlled his right hand.
