  • Patent number: 4672558
    Abstract: A touch-sensitive data input device for use with a computer system having a display screen has a demountable bezel which establishes a grid of light beams in front of the display screen. Misalignment between the display screen frame of reference and the bezel frame of reference is corrected by the calculation of coordinate transforms which are applied to bezel grid coordinates to translate same to display screen coordinates. The coordinate transforms are generated by the computer in accordance with a program of instructions executed in a preliminary bezel alignment procedure.
