BBC that the dev kit would give software developers a standard means of providing an interface for virtual reality headsets, like the Oculus Rift.
The report says the kit will launch during Valve's Steam Developer Days conference, which begins on January 15 in Seattle. Coomer added that "there's also technology in development at Valve based around head-tracking and headset manufacture and design," and that Valve is "working with other companies right now but we have not made any specific announcements."
Valve has some internal experience with virtual and augmented reality headsets in the past, as former Valve engineers Jeri Ellsworth and Rick Johnson were granted permission to take the Cast AR glasses project with them when they left the company in February 2013. The now-independent Cast AR augmented reality headset went to Kickstarter in October, and earned $1,052,110 from backers in a month. Additionally, Valve added a virtual reality support category to Steam for the Oculus Rift in December. Oculus VR has received more support from Valve these days, as seen in the headset manufacturer's latest model, which we took for a test drive at CES 2014 this week.
