[[SteamVR ]] is a [[Virtual Reality Platform]] developed by [[Valve]] as an extension of [[Steam]]. 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.
As a platform, SteamVR not only supports its own HMDs such as the [[Vive]] but also other HMDs like the [[Rift]].
==Devices==
===HTC Vive===
'''[[HTC Vive]] ''' or '''VCV1''' is SteamVR's first commercial product. Pre-orders for the device began on February 29, 2016. Units shipped on April 5, 2016. ===HTC Vive Developer Editions==='''[[HTC Vive DK1]]''' or '''VDK1''' is SteamVR's first development kit. The HDM was a partnership between Valve and HTC. It was announced on March 1, 2015 and showcased during the GDC 2015 between March 2 - 6. When paired with 2 [[SteamVR Base Stations]] and 2 [[SteamVR Controllers]], HTC Vive can accurately track the position and movements of your head and hands within the 15 by 15 feet space. '''[[HTC Vive Pre]]''' or '''VDK2''' is SteamVR's second development kit. It improved upon VDK1 in many areas, including the implementation of a pass-through camera on the HMD. 7,000 units were shipped to select developers in January and February 2016.
==Accessories==
===SensorsTracking==='''[[SteamVR Base Stations]] ''' - the dual Base Stations are part of the laser [[Lighthouse]] tracking system of SteamVR. They These small, rectangular objects are placed in the opposite corners of the room, near the ceiling. They track serve as reference points that enable the position [[positional tracking]] of your HMD and SteamVR controllerswithin the 3D space. The Base Stations are able enable Lighthouse to track your head and hands with accuracy, low latency and sub-millimeter precision within a specified space (currently about 15 by 15 feet). Each sensor 2 circular chambers that spin at high speed emitting lasers. Initiated by laser diode, the invisible lasers sweep across the room. They are detected by sensor carrying devices such as the HMD or the controllers.
===Input Devices===
'''[[SteamVR Controllers]] ''' - these wireless controllers look like a pair of nunchucks with sensors on top. Each hand holds 1 of the 2 wireless controllers. Each controller has a trigger and circular haptic trackpad. The sensors allow the controllers to be tracked by the SteamVR Base Stations with the same way as the [[HMD]]. The controllers are tracked with very high precision and low latency.
The sensors on the controllers are [[photodiode]]s.
==Apps==
'''[[HTC Vive Apps]]'''
==Developer==
'''[[OpenVR API]]'''
==Technology==
===LighthousePositional Tracking==='''[[Lighthouse]] ''' is a laser-based [[positional tracking ]] system developed by [[Valve]] for SteamVR. It tracks the position and orientation of the user's HMD and controllers in real time.
===Chaperone===
'''[[Chaperone]] ''' 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 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.
==DeveloperFeatures=='''[[Dashboard]]''' - Steam overlay for [[VR Apps]]. '''[[SteamVR Desktop Theater Mode]]''' - Play non-VR Steam games in VR on a large virtual home theatre. '''[[SteamVR Home]]''' - [[SteamVR Collectibles]] [[SteamVR Media Player]]
==History==
'''March 1, 2015 ''' - SteamVR and HTC Vive were officially announced on March 1, 2015 in World Mobile Conference. '''March 2 - 6, 2015''' - SteamVR and HTC Vive were showcased first time to the public. '''April 21, 2015''' - Sign-ups for the Developer Edition of HTC Vive began. '''April 30, 2015''' - [[OpenVR]] SDK was released. '''June 5, 2015''' - HTC Vive Developer Editions (HTC Vive DK1) began shipping to developers selected by Valve. '''January 5, 2016''' - HTC Vive Pre (HTC Vive DK2) was announced. 7000 of the HMD will ship to select developers in Q1 2016.
'''April 305, 2015 2016''' - [[OpenVR]] SDK was HTC Vive CV1 is officially released.
'''June 17 2016''' - SteamVR supports [[Oculus Touch]] [[controllers]], dual [[Constellation sensors]] and [[Room-scale VR]] with [[Oculus Rift]].
