An anonymous reader writes "The itinerary for Steam Dev Days 2014 lists two talks by Valve's internal virtual and augmented reality researchers, Michael Abrash and Joe Ludwig. Abrash's talk, titled 'What VR Could, Should, and Almost Certainly Will Be within Two Years' will feature a demonstration of Valve's secret prototype VR headset that is 'capable of stunning experiences.' Ludwig's talk 'Virtual Reality and Steam' will discuss how Valve will be adapting Steam to VR to 'support and promote Virtual Reality games.' Rift inventor and Oculus co-founder Palmer Luckey will also be taking to the stage at Steam Dev Days to speak on best-practice for VR development." There's a hint that they might be showing off a head mounted display featuring a low persistence display, which would be great news for those of us that get the urge to hurl when playing Doom on a conventional display. If you missed it you might want to check out the slides and notes (PDF) from Michael Abrash's GDC2013 talk on VR.
