The author looks at the potential 'worldchanging' implications of three virtual reality technologies: Augmented Reality, Virtual Worlds, and Simulations.
Computer-generated scenery can be realistically added to live video footage, using a machine vision system developed at Oxford University.
The classic arcade game PacMan has resurfaced on the streets of Singapore using ?augmented reality? technology developed by military-backed scientists at the University of Singapore.
An emerging technology known as ?augmented reality? will allow people peering through computer-fueled goggles to overlay virtual images atop those of the real world.
Computer scientists are developing a new offshoot of virtual reality, "Augmented Reality", that adds virtual information to a user's sensory perceptions.
Researchers at Columbia University are developing an Augmented Reality system which can superimpose computer-generated text, graphics, 3-D animation, sound, or any other digitized data (virtual 'Post-It Notes') on the real world through sophisticated goggles.
