Virtual reality
The 1990s saw the first widespread commercial releases of consumer headsets. In 1991, Sega announced the Sega VR headset for arcade games and the Mega Drive console. It used LCD screens in the visor, stereo headphones, and inertial sensors that allowed the system to track and react to the movements of the user's head. In the same year, Virtuality launched and went on to become the first mass-produced, networked, multiplayer VR entertainment system. It was released in many countries, including a dedicated VR arcade at Embarcadero Center in San Francisco. Costing up to $73,000 per multi-pod Virtuality system, they featured headsets and exoskeleton gloves that gave one of the first "immersive" VR experiences. "Computer Gaming World" predicted "Affordable VR by 1994".
Videoplace
In the mid-1970s, Myron Krueger established an artificial reality laboratory called the Videoplace. His idea with the Videoplace was the creation of an artificial reality that surrounded the users, and responded to their movements and actions, without being encumbered by the use of goggles or gloves. The work done in the lab would form the basis of his much cited 1983 book Artificial Reality. The Videoplace (or VIDEOPLACE as Krueger would have it), was the culmination of several iterations of artificial reality systems: GLOWFLOW, METAPLAY, and PSYCHIC SPACE; each offering improvements over the previous installation until VIDEOPLACE was a full blown artificial reality lab at the University of Connecticut.
