Context in ubiquitous computing and pure azimuth location model

LI Cai-xia, CAO Qi-ying (Department of Computer Science and Technology, Donghua University, Shanghai 200051, China)  
High precision in indoor location is the preliminary problem of location-aware research in ubiquitous computing. The concept of context in ubiquitous computing is firstly introduced. In terms of the "where" in context, some issues are argued. By analyzing the problems in indoor locating system, a model about infrared passive location is then given, and this model can determine the user's position according to the azimuth angles that have been measured. It reaches the high precision in indoor location system. At last, it is proved that the model can get the accurate position of a target.
