TaPuMa stands for tangible public maps. These are digital, touch-screen maps on which you can place everyday objects (e.g. plane tickets, cash, credit cards, cell phones, chewing gum) and get access to relevant, just-in-time location information. If you were using a TaPuMa at an airport, for example, and you placed your boarding pass on the map, the map would show you how to get to your gate. If you put your credit card on the map, it could tell you the location of an ATM or money exchange.
