Hi Charmaine - The Storyteller app is designed for use in Melbourne Museum. The content is not available (apart from the trailer video at the start) until the device running the app is connected to the museum Wi-Fi. The content is triggered by Bluetooth beacons which are located next to objects (e.g. the ambulance and the Duigan in the foyer) and other areas with deeper content within the exhibition itself.
Upon entering the exhibition, the app prompts each visitor to select a character to follow and the content os downloaded over Wi-Fi to the device.
