ABSTRACT:
A method and device for monitoring the position of a second point relative to a first point. A magnetic field is produced from the first point and received at the second point to produce an output signal therefrom. Preferably, the magnetic field is produced by a transmitter located at the first point and is received by a receiver located at the second point. The position of the first point relative to the second point is then determined by using the output signal. Preferably, the first point and the second point are both freely movable and therefore, both the transmitter and the receiver are mobile. As well, preferably both the first and second points are located on a human body. Finally, preferably, a feedback signal is produced for indicating the determined position of the second point relative to the first point. The determined position of the second point relative to the first point may be compared with a preset reference position such that the feedback signal indicates a discrepancy between the position of the second point relative to the first point and the preset reference position.
