  • Tracker touch apparatus utilizing magnetism for tactile feel
    Patent number: 5129301
    Abstract: A tracker touch apparatus used with a keyboard apparatus having a plurality of selectively depressed keys includes at least one strip magnet support by the apparatus in a position transversing over the tops of the keys. A metal plate is secured to the top of each key of the keyboard in a position just below the strip magnet. Initial depression of a keyboard key is resisted by the magnetic attractive force of the strip magnet for the metal plate secured to the depressed key. The magnetic resistance to keyboard key depression imparts to the keys a desired "feel" of depression.
