There is provided a method and apparatus for an improved computer pointing device. The present invention facilitates positioning the computer cursor and includes a pointing device (20) for providing coordinate input signals and a gain control device (30), preferably operable by a foot pedal, for providing gain signals, wherein gain is defined as the ratio of the cursor movement along the y-axis and x-axis relative to the corresponding amount movement of the pointing device along the y-axis and x-axis. The coordinate input signals and gain signals are received by a processor (50). The processor is operative to execute a program that scales the coordinate input signals as a function of a gain value determined from the gain signal. The processor then outputs the scaled coordinate input signals in a form simulating a mouse output. <IMAGE> |
