SteamVR offers a 360 degrees, full room [[VR]] experience. It was officially announced on March 1, 2015 during the Mobile World Congress. Valve partnered with [[HTC]] to release SteamVR's first [[device]], [[HTC Vive]], a VR [[HMD]] similar to [[Oculus Rift]]. Unlike Oculus, SteamVR features a [[holodeck]] experience, allowing the users to move and position themselves freely within a confined space.</ref>

==Developer=='''The SteamVR APIs and runtimes provide support for VR [[OpenVR APIhead mounted displays]]'''and accessories to a standard desktop computer.
==Technology=====Positional Tracking==='''SteamVR typically operates from within [[LighthouseSteam (service)]]''' is , but it does not require the service to work at a laser-based [[positional tracking]] system basic level. Video games can be developed by [[Valve]] for and played with SteamVR. It tracks the position and orientation of without having to access the user's HMD and controllers in real timesteam store.
===Chaperone==='''SteamVR launches into [[ChaperoneSteamVR Home]]''' is a system that helps to prevent users from bumping into physical objects or moving outside of the sensor range while using the HMD. The system differentiates soft and hard boundaries. Soft boundaries are the space designated for the specific app or detectable by the sensors while hard boundaries consist of physical walls, obstacles and objects.
When you move near the edge of the "holodeck", virtual grid walls would appear There is an in your display. These walls indicate that you are at the boundary of the sensors or near physical walls of your room. The walls would disappear when you move away from the boundary-application overlay available called [[Dashboard]].
==Features=='''It uses the [[Dashboard]]''' - Steam overlay for [[VR AppsChaperone]]system.
'''== Room Scale VR =={{Main|Room scale}}One of the primary contributions of SteamVR to the VR industry was Room Scale VR, or 6DOF VR. To accomplish this, SteamVR uses the [[SteamVR Desktop Theater ModeLighthouse tracking system]] for [[pose tracking]]''' - Play non-VR Steam games in VR on a large virtual home theatre.
'''The lighthouse system uses base stations that are placed at opposite sides of the room. The base stations send out [[SteamVR Homeinfra-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 [[SteamVR Collectiblespose (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>
