A museum mobile game for children using QR-codes

We present a mobile game to play a museum treasure hunt, addressed to students that are about 11-14. They have to search for the " materializations" of the solutions to a sequence of riddles, and to photograph them by personal camera phones. The letters of a secret word are orderly provided on right answers, spurring the interest for the exhibition through the cellular phone. The novelty is the use of QR-Codes, a kind of 2D codes, to identify the correct answers and to enjoy some other services. A preliminary field test in the Norsk Telemuseum gave very good results.
