Emerging mobile and indoor tracking technologies are of great interest for research and interpretation in science museums. As the cost of hardware decreases for indoor wifi, iBeacon, RFID and near field communication, science centres can afford to run experiments. They can also support focused projects to enhance visitor research by automating consent, anonymizing and recording whole-visit data histories or explore possibilities for location-specific or context-aware content and interactivity. Yet current theoretical use cases and ideal scenarios have little resemblance to real world experiences. In the quest for robust mobile tracking apps for general visitors, panellists will report on their own research and results and the promising indicators that are starting to emerge from this rapidly evolving field.
