An app for discovering audio observations in the Rijksmuseum. The app was used to test research insights; the result of a collaboration between the Rijksmuseum and the University of Amsterdam. Johanna Barnbeck, researcher at the University, experiments with interfaces that combine the physical and digital world. Walking through the museum, visitors can access stories when they are near certain artworks. When standing close enough to catch the signal, the story pops up on the app screen. The technique behind this uses Estimote beacons; electronical devices which are placed in selected areas around the museum.
