The lighthouse system uses base stations that are placed at opposite sides of the room. The base stations send out [[infra-red light]] sweeps which are detected by the headset, controllers, and accessories at multiple sensor points on each object. Based on the exact timing data of when the light is detected at different parts of the tracked objects, a tracked object can determine its [[pose (computer vision)]] within the tracked area.<ref>{{Cite web |last=vradmin |date=2017-05-05 |title=SteamVR Lighthouse |url=https://www.vrs.org.uk/virtual-reality-gear/motion-tracking/steamvr-lighthouse.html |access-date=2022-10-11 |website=Virtual Reality Society |language=en-GB}}</ref> The system was codeveloped by Valve and HTC and then opened up to third party hardware developers in 2016.<ref>{{Cite web |last=Matney |first=Lucas |date=2016-08-04 |title=Valve opens up the HTC Vive's tracking system to third-party developers |url=https://techcrunch.com/2016/08/04/valve-opens-up-the-htc-vives-tracking-system-to-third-party-developers/ |access-date=2022-10-11 |website=TechCrunch |language=en-US}}</ref>
