Japan.Locationandcontextawarenessarefundamentstonext-generation mobile and pervasive computing
systems. Pervasive computing is a model of computing in which computation is everywhere and
computer functions are - tegrated into everything. The ultimate aim is to make information 
applications and services available anywhere and at anytime in the human environment in a ?uid
manner appropriate to our current context. Once away from the desktop  we ?nd ourselves in a
wide variety of contexts and hence situations. For computing to be relevant and useful in these
emerging situations we must rely on a range of contextual cues. Context includes phys- logical
environmental  and computational data  whether sensed or inferred. In addition  context
includes details of a user's activities  goals  abilities  pref- ences  a?ordances  and
surroundings. With location and context awareness we can expect computers to deliver
information  services  and entertainment in a way that maximizes convenience and minimizes
intrusion.
