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.
