Abstract:
A stylus for use in a digitizer coordinate input system, the stylus comprising:a housing;electronic circuitry disposed within said housing;a rotatable finger wheel or dial that is rotatable about a central axis by a user, wherein a degree .theta. to which said finger wheel is rotated determines the extent to which a control or graphical parameter utilized by the digitizer coordinate input system is varied;said finger wheel including a plurality of teeth defined in a peripheral portion thereof;a gear wheel including a first set of teeth for meshing with said teeth of said finger wheel and a second set of teeth for meshing with corresponding teeth on a potentiometer so that the potentiometer detects said degree .theta. to which said finger wheel is rotated and causes said parameter to be varied as a function thereof; andwherein said first set of teeth on said gear wheel defines a peripheral portion having a different diameter than a peripheral portion of said second set of teeth on said gear wheel.
