Filed: 1983-12-12
Abstract: A screen is disclosed on the surface of which a certain number of resistant conducting emitter strips and insulated conducting receiver strips are laid, the emitter strips being parallel-mounted with the terminals of a voltage generator and the receiver strips being interlaid between the receiver strips such that a conducting receiver strip lies between two resistant emitter strips. The electronics of control comprises an exploring stage to control the receiver strip time-related exploration. Thus, when a sufficiently conducting object used to indicate a point, has touched the surface and bridges an emitter strip and a receiver strip, a higher potential is detected on the corresponding receiver strip and the ordinate Y is given by the strip order number-while the abscissa X is calculated from measuring the potential between each ends of the emitter strip and the object.
