An “old” and useful museum app are Qr Codes: those little square images that can be read by smartphone and I-phone, are able to improve info about any piece of museum collection, so they’re a good link between offline and augmented reality. The visitors can normally enjoy in watching artwork, and are also given the chance to get their own experience with this kind of individual tools.
A qr code can be coupled with an artwork: so it let the visitor get other info about it, like deepenings and so on, making the visit more interesting and involving. Then, reading the comment on your own phone means it can be simultaneously translated in many languages, as anyone needs.
These codes can be also used to know the best personalized tour to do in the museum, based on your wishes.
