Next week, Valve will release a software development kit that gives developers a standard way to implement controls in VR games, the BBC reports. Valve designer Brian Coomer has apparently said that the kit is days away and will be released at Steam Dev Days, which start on January 15th. Theres not much more detail given, but the company has already said it plans to reveal a prototype that will show what affordable Virtual Reality (VR) hardware will be capable of within a couple of years. Valve has previously worked in partnership with Oculus, whose latest VR headset — a prototype known as Crystal Cove — was announced at CES. The controller development kit will reportedly come as part of the larger set of software tools for Steam Machines, about a dozen of which have also been revealed this week.
