Among the handful of announcement Valve made at this year's Game Developers Conference was a subtle and hugely important one: Lighthouse. What in the world is Lighthouse? It's the "base stations" referenced in Valve's VR headset announcement, and it's even more important than the incredibly impressive headset. Valve president Gabe Newell compares it to USB and expects it to fundamentally change how people interact with virtual reality. "Now that we've got tracking, then you can do input," Newell said in an interview with Engadget this morning. "It's a tracking technology that allows you to track and arbitrary number of points, room scale, at sub-millimeter accuracy 100 times a second."
What that means for me and you is that Lighthouse puts your body into the virtual world with stunning precision. I tested it and can confirm: holy shit, yes, this really works. Want to reach out and touch something in VR? Lighthouse is how you'll do it.
