摘要：

Position tracking finds its application in the areas of medicine, sports and training, gaming and in general, Human Computer Interface (HCI). The system described here achieves 3 dimensional position and orientation tracking. The system mainly consists of a single-axis magnetic field transmitting inductor coil, tri-axis receiving inductor coil Inertial Measurement Units (IMUs) and microcontroller units (MCUs).With a fixed frequency AC magnetic field, a closed form solution has been proposed to find the position of the receiver (Rx) coil relative to the transmitter (Tx) coil. The system achieves a position jitter of less than 1mm up to a tracking distance of 1m.
