Atari Jaguar
A virtual reality headset compatible with the console, tentatively titled the Jaguar VR, was unveiled by Atari at the 1995 Winter Consumer Electronics Show. The development of the peripheral was a response to Nintendo's virtual reality console, the Virtual Boy, which had been announced the previous year. The headset was developed in cooperation with Virtuality, who had previously created many virtual reality arcade systems, and was already developing a similar headset for practical purposes, named Project Elysium, for IBM. The peripheral was targeted for a commercial release before Christmas 1995. However, the deal with Virtuality was abandoned in October 1995. After Atari's merger with JTS in 1996, all prototypes of the headset were allegedly destroyed. However, two working units, one low-resolution prototype with red and grey-colored graphics and one high-resolution prototype with blue and grey-colored graphics, have since been recovered, and are regularly showcased at retrogaming-themed conventions and festivals. Only one game was developed for the Jaguar VR prototype: a 3D-rendered version of the 1980 arcade game "Missile Command", entitled "Missile Command 3D", though a demo of Virtuality's "Zone Hunter" was also created for Jaguar VR demonstrations.
Windows Mixed Reality
In October 2016 during a hardware event, Microsoft announced that multiple OEMs would release virtual reality headsets for the Windows Holographic platform, based on Microsoft reference designs enabling room-scale virtual reality without external sensors or components. In January 2017, prototypes were presented at Consumer Electronics Show for release later in the year, and Microsoft later announced that it planned to release development kits for such headsets during the Game Developers Conference. These devices would be supported by the Windows 10 "Creators Update". At the Game Developers Conference in 2017, Microsoft stated that it intended to support Windows Mixed Reality headsets on Xbox One in 2018, specifically noting the capabilities of the then-upcoming Xbox One X hardware revision, but the company later stated that it was initially focusing on PC platforms first, and that it wanted to focus on wireless VR solutions for consoles.
