In an Always Best Positioned (ABP) localization system the output of different localization techniques are fused together to get an even better position accuracy. Besides the infor- mation about the position of a user, his viewing or walking direction is also important. This paper describes an exten- sion of our mobile APB system that uses RFID tags and infrared beacons. We describe how different direction in- formation – derived from different sensors or calculations – can be fused together with the help of Dynamic Bayesian networks.
