Abstract
A cursor control system and method for moving a cursor on a computer screen in response to movement of a ring over a keyboard. A ring contains a transmitter circuit which is activated by a switch positioned on the ring. A signal generated by the transmitter circuit is transmitted to a receiver attached to a computer keyboard. The receiver detects motion of the transmitter circuit over the keyboard and, in response, generates signals which are used to control the movement of the cursor on the computer screen.

23. A cursor control system comprising:
-
a computer input device which generates a signal representative of movement of the computer input device; motion prediction means for receiving the signal and detecting when the signal represents cursor movement substantially along a predefined axis; means for emphasizing portions of the signal representative of movement along the predefined axis relative to portions of the signal representative of movement in directions other than along the predefined axis when motion along the predefined axis is detected.
