Abstract
A finger-touch tracking system is provided, including a magnet, a magnetic field sensing unit, and a computing unit. The magnet generates a magnetic field. The magnetic field sensing unit moves relative to the magnet, and has a substrate and a plurality of sensors disposed on the substrate. The sensors detect a magnetic flux density of the magnet, so as to generate a tracking signal reflecting a relative position of the magnet with respect to the magnetic field sensing unit. The computing unit receives the tracking signal via a network, and employs the received tracking signal as an input instruction upon the magnitude of the magnetic field.
