Enhanced Hand Tracking When a user wears a tracker on their wrist, the software can predict the movements of the tracker even when it briefly goes out of the camera's view. This means that the software can anticipate the position of the hand when it leaves the tracking camera's line of sight or when the hand is obscured. 6DoF Object Tracking The VIVE Wrist Tracker uses the same tracking technology as the VIVE Focus 3 controllers. The LEDs are directly captured by the VIVE Focus 3 tracking cameras to achieve accurate 6DoF inside-out tracking. This allows the VIVE Wrist Tracker to be attached to real-world objects and tracked with full 6DoF capability. Upgrade from 3DoF to 6DoF For those who want to track smaller objects, you can attach a small 3DoF sensor to an item like a screwdriver or scalpel. The VIVE Wrist Tracker simplifies the tracking of handheld objects by combining the rotational data from the 3DoF sensor with the positional data from the VIVE Wrist Tracker, providing a complete 6DoF experience.
