  • Parallax induced pointing error avoidance method and means for systems using touch screen overlays
    Patent number: H716
    Abstract: In a system using a touch panel type of overlay on a cathode ray tube screen wherein multiple areas for user selection are presented on the tube screen, erroneous touch selection of displayed areas on the tube because of parallax-induced offset is avoided by assigning a guard band around each display area. The width of the band is designed to correlate to the amount of parallax error associated with the combined tube and overlay touch screen environment.
