Design and applications of a beer mat for pub interaction

We describe the design of an interactive beer mat for the support of entertainment activities in pubs. The mat uses a gravity sensor to sense motion and orientation in space and a pressure sensor to sense the weight resting on it. Care was also taken to preserve its original functions, such as absorbing superfluous liquids and providing advertising space. We present a number of activities supported by the mat and show how it can improve the profit of the pub and the mood of the crowd simultaneously.
