Building a Personal Memory for Situated User Support

Keeping a history of the user’s interaction with the environment is of use for many reasons. However, collecting, structuring, accessing, and reviewing such potentially large amounts of information is not trivial. In this paper we present our ideas for a memory model for pervasive computing applications addressing these questions. The proposed architecture allows applications to deliver ad-hoc support taking into account the user’s history and general attitudes as well as providing a personal diary to review events and retrieve memories. We also include a brief discussion of a novel user interface, which allows the user to bind services to general contexts based on her previous experiences.
