An iSpace is an environment that offers services to its inhabitants, such as re-routing communications, displaying information, adapting climate controls or monitoring their well-being. One main objective for iSpaces is awareness, i.e. the available services and devices of the iSpace must be aware of inhabitants and their contexts and intentions. In order to obtain the required information an iSpace can use a logical sensor network that allows abstracting from the physical implementation of sensors and provides the data for an automatic intelligent data analysis (IDA). In this paper we describe an approach to automatic IDA in the context of sensor networks and give an example from the telecare area, where the iSpace is represented by a sensor-rigged home of a person whose well-being needs to be monitored in the context of social care.
