Domain Specific Services for Continuous Diagnoses in the Context of Ambient Assisted Living - AAL

摘要

This article broaches the issue of a human centered assistance system which implements a continuous health monitoring system based on situation recognition. Concerning the initiating background of Ambient Assisted Living, the assistance system, addressing the domain of geriatric home care, evaluates distributed sensor-, actuator- and communicator networks to afford situation dependent services for people with special demands. After an introduction to the field of research under consideration of essential exigencies, the architectural concept of the middleware and their coherent functional modules are described. Thereby, the focus lies on the preprocessing techniques and the probabilistic modeling through Hidden Markov Model, which are a sufficient solution for the delineation of discrete event systems. Mapping the medical problem of heart insufficiency (HI), we gain an ostensive instance for the demonstration of our approach and obtain and present first results based on real and simulated data for the demonstration and validation of the system.
