The HTC Vive is a virtual reality headset developed by HTC and Valve Corporation. The headset uses "room scale" tracking technology, allowing the user to move in 3D space and use motion-tracked handheld controllers to interact with the environment. The HTC Vive was unveiled during HTC's Mobile World Congress keynote in March 2015. Development kits were sent out in August and September 2015, and the first Consumer version of the device was released on April 5th, 2016.
Vive Headset: The Vive headset has a refresh rate of 90 Hz and a 110 degree field of view. The device uses two screens, one per eye, each having a display resolution of 1080x1200(2160x1200 combined pixels). Safety features include a front-facing camera that allows the user to observe their surroundings without removing their headset. The software can also use the camera to identify any moving or static objects in a room; this functionality can be used as part of a "Chaperone" safety system, which will automatically display a virtual wall or a feed from the camera to safely guide users from obstacles or real-world walls.
Vive Controllers: The wireless controllers are the hands of virtual reality, making a more immersive experience for the user. The controller has multiple input methods included a track pad, grip buttons, and a dual-stage trigger and a use per charge of about 6 hours. Across the ring of the controller are 24 infrared sensors that detect the base stations to determine the location of the controller. The Steam VR Tracking system is used to increase the connection of the controller by giving wireless real time feedback of 360 degrees to the host.
