In this article we present a novel, hybrid graph spatial representation for robot navigation. This representation enables our mobile robot to build a model of its surroundings whi...
We characterize the dynamic data management problem for location based services(LBS) in mobile environments and devise a cost model for servicing both location independent and loc...
Mobile location-dependent information services (LDISs) have become increasingly popular in recent years. However, data caching strategies for LDISs have thus far received little at...
— This paper describes a probabilistic framework for navigation using only appearance data. By learning a generative model of appearance, we can compute not only the similarity o...
For many years mobile visitor information systems for museums or exhibitions are a topic of research. Research prototypes aim to provide the user with powerful means for organizin...
