1995 brought us yet another Gyro based VR Game system, the X-O-Tron VR, a descendant of the original non-electronic gyro-exercise system, the Orbotron. Initially inspired by the March 1992 release of Lawnmower Man, the first gyro VR systems appeared that summer (full disclosure – my company built a prototype system for a client in the spring of ’92 and then offered our own before the end of the year.)
The X-O-Tron VR came from the same folks who designed and built the Orbotron. It had two features that nobody else was offering: a wireless HMD and the ability to spin the gyro completely upside-down and back. While the helmet wasn’t tracked, there were shaft encoders on the gyro bearings to detect the gamer’s orientation. The game electronics were a 3D0 home game system. Read more in the X-O-Tron-VR Brochure.
