HTC Vive – Technology
But it’s the Valve Lighthouse base stations and the tracking dots on the headset and controllers that help make the HTC Vive the best VR experience we’ve tried to date. Rather than using a camera like the Project Morpheus and the Oculus Rift, Valve’s SteamVR system uses lasers to track your head and hand movements with sub-millimetre accuracy. These lasers are optimised for low latency, so whatever you do when playing in virtual reality will be reflected instantly without any motion blurring or delay. You place two of these Valve Lighthouse laser bases at opposite corners of the room in order to make sure that you’re tracked wherever you are in the safe zone.
That really becomes apparent when you realise the HTC Vive has a 15 x 15ft tracking area, which allows you to get up and walk around in your virtual reality experience. I’ve experienced motion sickness with VR headsets before, including the Oculus Rift, but using the combination of Valve’s enhanced virtual reality tech and the controllers, I never felt like there was a miscommunication between my brain and my body.
It does help that the HTC Vive has the highest-resolution screens of all the current virtual reality offerings, offering 1200 x 1080-pixel-per-eye displays with refresh rates of 90fps.
