Oculus Rift isn't the only company looking to put a VR gaming headset on your noggin'. Valve, the team responsible for Steam and the Half-Life series is experimenting in the space too, and images showing a prototype version of the kit are now starting to make their way online.
The latest batch comes from the Boston VR Bender developer meet-up, where Valve is said to have offered a prototype up to attending devs for a quick demo. As you can see in the image above, it makes use of trackable spots on all surfaces of its forward-facing casing, presumably to handle depth tracking, and requires a separate camera sensor be placed on a surface in front of the headset to achieve life-like tracking.
The prototype is said to be more portable than previous builds that Valve has publicly shown, as the company makes refinements ahead of a presumed consumer release. However, Valve has so far started that its intention is to aid fellow VR teams to get their products out of the door first, such as the Oculus Rift, before considering any opportunity for its own version.
