A situation-aware support model and its implementation

Ubiquitous Computing becomes a popular research field, with the progress of sensor networks, automatic identfication techniques etc. One of the hottest topics in ubiquitous computing is context-aware service, provided based on users' context, e.g. location and interests. Though many researches have been done in users' context-aware based services, it still a hard challenge to identfy the situation of users in a systemic and precise manner to provide personalized services adapted to the users' situations. In this paper, we propose a situation-aware model to specify the situations of the users, define actions on the situations, so that when the situations really happen, defined actions will be triggered to provide services to the users. In order to realized the proposed model, we implement a ubiquitous platform called ubiquitous tiles system, by which users' identifications and location can be acquired with corresponding relation between a user and his/her location, to detect the situations.
