Valve's foray into virtual reality technology was absent from the recent CES 2014 event in Las Vegas, where the Steam developer's activities were instead focused on promoting Steam Machines, a new range of living-room targeted PC form factors.
But it sounds like we may not have to wait too much longer for more details on Valve's VR plans, as comments made by Valve designer Brian Coomer indicate that they'll have some in-house tech to share at next week's Steam Dev Days event in Seattle, a press-excluded developer conference that the studio is hosting in its home town.
Valve designer Brian Coomer says the company is "days away" from releasing a VR software development kit that will give game makers a standard way to provide an interface for VR controllers.
The kit will be released at Valve's forthcoming Steam Dev Days conference due to take place on 14-15 January in Seattle.
Valve's interest in VR has been long known, says Mr Coomer, as has its relationship with Oculus Rift.
"There's also technology in development at Valve based around head-tracking and headset manufacture and design," he says.
"We are working with other companies right now but we have not made any specific announcements."
The SDK described by Valve is likely to be some manner of toolset geared around standardising the way things like user-interfaces and player control methods work in VR, based on the extensive research they have already done with game's like Team Fortress 2.
Whether or not Valve will be revealing any of its own VR hardware prototypes anytime soon is unclear, but like everything else they've been doing lately, it sounds like open collaborative development is their goal and their software solutions intend to be compatible with other devices like the Oculus Rift, and benefit the entire VR movement.
