The Tracker is the object being tracked by the Cameras. It can be used on a VR headset, to track hands, or any accessories you want to create ! The Tracker runs on battery for at least 3 hours. It includes a 9DOF accelerometer, magnetometer, gyroscope to send orientation data. Finally a GPIO port allow you to connect sensors directly to the Tag to transfer the sensor’s data directly to the Users. Each Tracker is uniquely identified. The identification code can be read under Tag, by scanning the QR Code or NFC Tag for fast association.
