  • Method and apparatus for improved electronic touch mapping
    Patent number: 4622437
    Abstract: An improved touch-panel and method of increasing the percentage of useful area of a touch-sensitive panel include electrode elements in electrical communication with an electrically conductive layer of known spatial impedance characteristics. The touch-panel structure incorporates improved electrode structure and electrode to impedance layer interfacing elements which impart a more linear mapping function within an expanded touch-sensitive region of the resistive layer. The touch-panel can be utilized in a general touch-mapping system without resort to extensive mapping coordinate correction apparatus of earlier systems.
