id Software co-founder and lead programmer John Carmack showed off a prototype virtual reality headset at E3, and said development kits will release for it soon priced at $500 each.
The industry veteran gave PC Gamer a demonstration of the device
, which acts as goggles that block out all light and show the on-screen action via small screens in the headset.
As part of a Doom 3
demo, players could use a controller to walk around and shoot enemies, and then look around the environment via a head-tracker.
The head-mounted display, dubbed "Rift," was built by tech enthusiast Palmer Luckey, who plans to launch a Kickstart project to produce and distribute the open-source kit for other developers to tinker with soon.
The headset follows work from Valve's Michael Abrash, who is currently researching "wearable computing" prototypes
. Abrash said that the virtual reality gear will be "the most valuable thing I could do at Valve," with computer-generated graphics that are seamlessly overlaid in your view.
