The NonObvious app, an interactive screen for commenting ideas that is going to be used in a permanent exhibition for sustainable construction in Verden, Germany . The idea is that users in the exhibition can interact with the physical artefacts using QR / NFC, and use the social features supporting informal learning. The interactive screens can be connected to the exhibition platform to allow access through mobile devices and for user recognition and e.g. highlight comments that are from visitors with similar interest or professional profile.
