Context management for RFID-based distributed interaction spaces

Information system management in distributed interaction spaces is not an easy task because the information should be contextualized in the space it is being manipulated in order to keep it consistent and coherent to the users. For instance, museum visitors usually have difficulties to associate the information provided by an electronic guide while they are moving inside the building. The association/contextualization of the information to a physical space is not an easy task. This article presents the system of management of contextual information CAIM to solve this problem from the management point of view, allowing managing virtual contexts, and from the point of view of the end user. CAIM assures that the information is provided with coherent and consistent manner in the different contexts from distributed interaction spaces. The article shows a case of use study and an evaluation of CAIM system implemented by means of technology RFID.
