It's been a long road from where Valve started with VR. It was only a few shorts years ago that the company was letting select industry folk demo prototype VR hardware in its QR code-laden "Room." And now, Valve has its own consumer-facing VR headset, the HTC Vive; its own controller that looks like the space opera version of Sony's Move wand; and a positional-based tracking solution in Lighthouse VR. None of this has exactly caught us off guard -- Valve was always cagey when it came to questions of commercial hardware. But we weren't prepared for just how impressive the combination of all the VR tech truly is. In fact, our own Ben Gilbert called it the "best VR" he's experienced to date.
It's only fair, then, that Valve would want to look back on its own journey pioneering VR. And look back it did with a timeline of prototypes and R&D breakthroughs it had on display here at GDC. Care to take that walk down Valve's memory lane? Then treat yourself to the gallery below and be sure to head past the break for a video tour.
