All curious minds will be grateful for hints and signs that show them the best way to what they are looking for. We will present best practice examples of indoor navigation systems and visitor tracking, and will discuss the concepts of different projects. This will enable a comparison of different objectives and technical bases like Wifi or RFID. The focus will be on opportunities and limitations from the visitors’ perspective as well as from the museums’ point of view. What worked well, what went wrong – and where we go from here.
