TypeHead-mounted display

Glasstron was a series of portable head-mounted displays released by Sony, initially introduced in 1996 with the model PLM-50.[1][2] The products featured two LCD screens and two earphones for video and audio respectively. The products are no longer manufactured nor supported by Sony.[citation needed]

The Glasstron was not the first head-mounted display by Sony, with the Visortron being a previous exhibited unit.[3][4] The Sony HMZ-T1 can be considered a successor to Glasstron.[2] The head-mounted display developed for Sony during the mid-1990s[which?] by Virtual i-o is completely unrelated to the Glasstron.[1]

One application of this technology was in the game MechWarrior 2, which permitted users to adopt a visual perspective from inside the cockpit of the craft, using their own eyes as visual and seeing the battlefield through their craft's own cockpit.[5]
