We already saw the new Vive virtual reality headset that Valve and HTC are working on, but they're not stopping there. Hardware engineer Alan Yates says that its Lighthouse room-scale tracking system brings the "high-resolution, high-speed tracking" that you need for a quality VR experience. According to Yates, the system is cheap enough to integrate into TVs, monitors, headsets, input devices or mobile devices. There's not a lot of detail on what exactly it includes, but it sounds a lot like the extra LEDs Sony just revealed on its new Project Morpheus prototype, and its PS Move controller. Those let the system track it with a camera to see how the wearer is moving in greater detail. Valve will make Lighthouse available to hardware manufacturers "freely," and we'll probably be looking for VR-ready stickers on our next TV or monitor.
