Enhance Virtual Reality

Enhance Virtual Reality

1. What is virtual reality?

   • Is a illusory environment
     • Gives the user the impression of being somewhere other than where they are
     • Attempts to create the actual experience, combining vision, sound, touch and actual feelings
       • Give the brain a realistic set of sensations

2. Practical applications of virtual reality

   • Treat people suffering from certain phobias
   • Treating social anxieties
   • Research, education, and training
   • Business

3. What engineering advances are needed

   • Placing realistic “virtual people” in the scene to interact with the user
   • identifying just what level of detail is necessary for a user to accept the illusion
   • Touch poses an especially formidable challenge.

4. How does it work?

   • A display screen mounted on the head so as to cover the eyes and ears
     • Communicates with a computer.
       • The computer stores all the necessary information to generate the virtual scenes and sounds.
         • The visual and auditory information is transmitted separately to each eye and ear
           • Giving realistic stereovision images and two- or three-dimensional impression of sounds.
             • As users move their heads
               • The computer quickly generates new images to reflect what people moving about in a real world would see next
