Abstract: A coordinate processor for a computer system having an absolute position pointing device (10) such as a touch sensitive display screen comprises stimulus detection means (200) for detecting a tactile stimulus of an absolute position pointing device (10) directed to a point within a data display area (610) of a computer system. The processor further comprises coordinate locking means (210-320) for locking a current cursor position to the point within the display area corresponding to the tactile stimulus in response to said stimulus exceeding a predetermined threshold value. The processor permits the computer system to distinguish a stimulus of the pointing device (10) for repositioning the cursor within the data display area (610) from a stimulus of the pointing device (10) for issuing a button click command to the computer system. The processor may be embodied in an electronic logic circuit within a pointing device adapter portion of the computer system. Equally, the coordinate processor may be in the form of a central processing unit operating under the control of a computer program.
