Augmented Reality and Virtual Reality Visors

Virtual Reality uses computer technology to create a simulated, three-dimensional world that a user can explore while feeling as if he were in that world. A virtual reality visor is a head mounted display that feeds the user three-dimensional images that appear to be life-sized from the perspective of the user.The virtual reality visor tracks the user's motions, particula­rly his head and eye movements, and correspondingly adjusts the images on the user's display to reflect the change in perspective

Augmented Reality is a new technology made possible by digital video equipment. Augmented Reality devices overlay computer generated "virtual" images (as described above) over live video feeds, merging them together as seamlessly as possible.
