This paper presents an AC magnetic field based High-Definition Personal Area Tracking (PAT) system. A low-power transmitter antenna acts as a reference for three tracker modules. One module, attached to the Head Mount Display (HMD), tracks the position and orientation of user’s head and the other two hand-held modules act as an interface device (like virtual hands) in Virtual Reality. This precise, low power, low latency, non-line-of-sight system provides an easy-to-use human-computer interface. The system achieves a precision of 1 mm in position with 0.1 degree in orientation and an accuracy of 20 cm in position at a distance of 2 m from the antenna. The transmitter and the receiver consume 5 W and 0.4 W of power, respectively, providing 140 updates/sec with 11 ms of latency.
