Abstract: A tracking system and a device integrating an existing positional tracking system and a docking mechanism include a tracking system hardware module, a docking mechanism, and a positional tracking software module and are adapted to capture a user's finger movement and send in real time and synchronously the user's finger movement to a computer. The docking mechanism is compatible with an existing third-party positional tracking system such that the device can operate in conjunction with existing, commercially-available positional tracking systems, for example, HTC VIVE Tracker, and Oculus Quest, and thus is applicable to an existing game engine.
