翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Questron (toy) ： ウィキペディア英語版 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? )〕 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 )〕 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. If both diodes activated, a small musical tune would be played to signify the "goal", or end of the lesson. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Questron (toy)」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
