Pico Motion Trackers are a great way to add leg tracking for Pico 4 Ultra and Pico 4 and Pico Neo 3 headsets. Each Pico Motion Tracker has an IMU (inertial measurement units) that contains a small accelerometer and Gyroscope. But unlike other IMU trackers like Mocopi, Pico Motion Trackers also feature 12 infrared LEDs each, which are tracked by the headset for two purposes.
Firstly, they’re used to enable rapid initial calibration, where you simply stand still and look down. They are then used for true 6DoF tracking when a tracking camera is in the view of the tracker. This hybrid method is something we’ve never seen before. It should provide a higher quality output than pure IMU trackers at a significantly lower cost than Vive Trackers.

Each tracker weighs just 27 grams, offers a claimed 25 hours of battery life, and is charged via standard USB-C.
Pico Motion Trackers are available to preorder in China for Y=400 for a pair, which equates to just below $60. Shipping is set to begin on September 2, the same day as the new

ByteDance says the trackers will be supported in PC VR apps such as VRChat via the Pico Connect PC VR streaming app, as well as over 20 standalone VR games on the Chinese Pico Store.
