Abstract:
An apparatus for remotely controlling a digital processing system, comprising:a housing having a wall with an outer scrolling surface over which a finger of a person's hand is movable in a scrolling movement, wherein the finger is moved back and forth over the scrolling surface; a scrolling detector located within the housing, detecting the scrolling movement remotely through the wall, and generating a scrolling signal, wherein the scrolling detector includes a plurality of capacitor terminals adjacent one another and within the housing, and disposed along an arc such that the capacitor terminals are equidistantly spaced from the outer scrolling surface, the capacitor terminals detecting a change in capacitance as the finger moves in the scrolling movement; a cursor positioning detector secured to the housing, being actuable by the hand to generate a position signal; and a transmitter which transmits the scrolling signal and the position signal to the digital processing system.
