Ambient Assisted Living system for in-home monitoring of healthy independent elders

In this work, the process followed for the development of a specific Ambient Assisted Living system is presented. The proposed systems has been designed to monitor elders which live alone and want to keep living independently. The process covers all the phases in intelligent system development: requirement analysis, conceptual model specification, architectural design and evaluation. One of the main contributions of the proposed work is an exhaustive evaluation methodology that is integrated in the development process. A relevant characteristic of the evaluation process is that, from initial phases, commercial presentations of the products functionalities is possible. Another important contribution is related with the capability of the system to adapt its behavior to that of the monitored elder. The presented system is called Necesity. It has become a commercial product which is already working and giving service to elders in the South-East of Spain.

► We present a totally developed monitoring system for elderly people. ► We address how to model elderly people at home and their context. ► The model consists of a simple automaton whose transitions are modeled by semantic web rules expressed in SWRL. ► An adaptive mechanism which takes routines of the subject into account is created to detect abnormal situations. ► The system is working now in real houses as a final product.
