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".
Optical head-mounted display
In January 2013, the Japanese company Telepathy was founded by the augmented reality entrepreneur Takahito Iguchi. At SXSW 2013 the company unveiled the Telepathy One, an eyewear display that consists of a small micro projector to create a virtual 5-inch screen that appears to float in front of the wearer's eye and a built-in micro camera. It uses an OS built off Linux and can connect to other devices via Bluetooth. It allows users to receive e-mails, check updates on social networks, and even share whatever scene the user is looking at with his friends. A Consumer version is expected to hit the US before the 2013 Christmas season.
