ABSTRACT:
An improvement in the system for educational and entertainment purposes in which the user is afforded an opportunity to select a correct answer for a question from among a plurality of possible answers is disclosed. The improvement includes a composite laminated card of insulated material with a plurality of arranged electrically conductive paths between sets of contacts, one set being for a hand held indicator probe and the other set for contact with a finger. The indicator probe has a conductive probe tip for contact with the card and the conductive contact with the user's hand holding the probe. The visual indicator in the probe indicates the presence of a continuity path extending from the probe through the card through the user's finger in contact with the finger contact, through the user's body and again to the probe. Very low voltage and currents are employed to implement the probe for use with body resistance. The card is so constructed that the teacher may individually program the card or the cards may be mass programmed at the factory.
