User Assist Applications with Location Sensors Integration

In this video paper, we introduce two context-aware applications: a navigator, and a communicator which are implemented in our laboratory premises. The applications are developed on a software platform which supports the integration of several different kinds of sensors. Currently we use data from three location sensing methods and user activity data as sensor input. The navigator is used for guiding guests in our laboratory premises with varying accuracy according to the user’s position. The communicator combines voice over IP (VoIP) , instant messaging (IM) and email functionalities in a single application, and switches between methods of communication according to the user’s preference and context.
