Patent US 5,453,015

A system is provided for recording and evaluating audience responses, for example, answers given to questions posed in television quiz shows. Responses are sensed using, for example, a membrane switch array, and timing information is generated by a timer. Data identifying responses and associated timing information is stored in a memory for later recall. When the responses are recalled, the associated timing information can be used to verify that a quiz-show participant made the response within the time period allowed according to the rules of the quiz.
