ABSTRACT:
Teaching or amusement apparatus consists of a substrate bearing printed intelligence and a detector pen or unit for use therewith. The detector pen discriminates between areas on the printed substrate by means not visible to the naked eye e.g. by a difference in magnetic properties, infrared reflective properties or capacitative properties of different parts of the printing. Depending on the type of printing and the degree of complexity of detection, a wide variety of games and teaching aids may be produced using this basic approach. A typical example is a quiz game where a question may be followed by five printed answers, only one of which is correct, that correct one being printed in a detectably different way from the others.
