Sega VR

Sega, flush with funds from the Sega Mega Drive (released as the Sega Genesis in North America), announced the Sega VR add-on in 1991.Fact|date=April 2007 It was based around an IDEO virtual reality headset (HMD) with LCD screens in the visor and stereo headphones.Fact|date=April 2007 Inertial sensors in the headset allowed the system to track and react to the movements of the user's head.

Because of development difficulties the Sega VR remained only a prototype, it was last seen at computer shows in 1993Fact|date=April 2007 and vanished from the release schedules in 1994. Four games were apparently developed for the system, each using 16 Mb cartridges that were to be bundled with the headset.Fact|date=April 2007

The company claimed the project was stopped because the VR was so real users would move while wearing the headset and injure themselves.Fact|date=April 2007 The limited processing power of the system makes this claim unlikely, although there were reports of testers developing headaches and motion sickness.Fact|date=April 2007

Sega went on to other VR projects for use in arcades and a similar add-on was reported but never seen for the Sega Saturn.Fact|date=April 2007 The project encouraged a brief flurry of other companies to offer VR products.
