Introduction
The EMF head tracking system consists of field coils in the walls of a booth that create X,Y and Z (or Horizontal, Frontal and Vertical) oscillating EM fields with different frequencies. The fields are sensed by a small pick-up coil mounted on a glasses frame worn by a subject. The signal is analysed and converted into a position of the subjects head relative to his/her default forward looking resting position.
