GAL, the Lower Saxony Research Network Design of Environments for Ageing, investigates how information and communication technology can provide for better environments for ageing. This paper describes a service oriented middleware platform for Ambient Assisted Living and its use in a number of different assistive systems developed in the GAL project: personal activity and household assistant, monitoring of preventive and rehabilitation sports, sensor-based activity determination, and sensor-based fall prevention and recognition. Besides a detailed description of the middleware platform and its elements and interfaces, central infrastructure services and their particularly applications in the different use cases are presented.
