Vive Tracker v1

The Vive Tracker is a small motion tracking accessory that can attach to real world objects and bring them into virtual reality. It was created by the Taiwanese company HTC and it is designed to work with the HTC Vive VR headset. The device communicates with the host computer wirelessly and each tracker needs its own wireless USB receiver. So, for each Vive Tracker, a free USB port is necessary. It can be attached to different real world peripherals developed by HTC, such a tennis racket, a ping pong paddle or a toy gun. Then, the tracker takes basic input from the peripheral it’s attached to, gathering its dimensions and sending the data to the lighthouse sensors, which then track the object in real time. For that, the device integrates eighteen SteamVR IR sensors to maximize the tracking fidelity of its spatial position and orientation. The Vive Trackers have 1500mAh lithium-ion batteries, providing up to four hours of continuous use.
