Questron (toy)

Questron was a battery-operated, interactive educational toy introduced in 1987 by Child's Play Ltd [Recall: Remember the Questron Books and Answer Wand? [http://copywrong.wordpress.com/2007/02/09/recall-remember-the-questron-books-and-answer-wand/] ] . Used in conjunction with special books, the reader could press the tip of the pen-like Questron to an answer to a question - with audible and visual guides showing whether the selected answer was right or wrong.

Technology

Questron used infra-red radiation to distinguish between different answer "areas" [Teaching and amusement apparatus - United States Patent 4990093 [http://www.freepatentsonline.com/4990093.html] ] . Two light-emitting diodes (one red, one green) would signify correct or incorrect answers and a small loudspeaker would add a sound effect to each answer.
