Slide 25

Virtual Reality - Immersion Key to the VR field is “immersion”. A VR situation is immersive in the event that it gives the client the sentiment being inside a scene, as opposed to just taking a gander at the scene. Genuine VR is nonexistent, yet we do what we can: Create a scene that is seen by the client as though they are in it. Permit the client to interface with items in the scene in something approximating a “natural” way. Acquire the greatest number of faculties as we can: Sight & sound are the primary ones we manage. Heaps of examination is start done on touch ( haptic interfaces). Taste & smell: overlook it, until further notice. http://graphics.gmu.edu
