Abstract: The present disclosure discloses an object position detector. The object position detector comprises a touch sensor formed as a closed loop and having a physical constraint formed on an upper surface of the touch sensor and coextensive with the closed loop. The touch sensor is configured to sense motion of an object proximate to the closed loop. The object position detector also comprises a processor coupled to the touch sensor and is programmed to generate an action in response to the motion on the touch sensor.

Abstract: A method and apparatus for recognition of handwritten symbols. A plurality of strokes is received at a common input region of an electronic device, wherein the plurality of strokes in combination defines a plurality of symbols. Sequential combinations of the plurality of strokes are analyzed with a plurality of symbol recognition engines to determine at least one possible symbol of the plurality of symbols defined by the plurality of strokes, wherein at least one of the plurality of symbol recognition engines is configured to identify symbols comprising a particular number of strokes.

Abstract: A pointing device some or all of whose elements are made from capacitive sensors. Such elements may include a rotary motion detector which includes a rotating member and a plurality of fixed capacitive detecting members; a rolling ball with patterned conductive surface and a plurality of fixed capacitive detecting members; capacitive touch sensors or capacitive switches to serve as mouse buttons; and a scrolling wheel, knob, or touch surface built from capacitive sensors. The pointing device further includes a capacitance measuring circuit and processor to measure variations of capacitance on the various capacitive elements and to determine the movement of and other activations of the mouse.
