We present our work on a sensor-based smart system automatically trained to recognize the activities of individuals in their home. In this paper we present and analyze a method for recognizing the indoor everyday activities of a monitored individual. This method is based on the data mining technique of association rules and Allen's temporal relations. Our experimental results show that for many (but...
Monitoring activities of daily living is one of the key functionalities expected from a Smart Living environment providing independent living services for elderly people. Simple state-change sensors have been considered to be a promising sensing technique to observe the environment and consequently provide the data required to form the basis to infer high-level behaviours. From a data analysis point...
In this paper the acoustic event detection and classification (AED/AEC) system developed under European Community's Seventh Framework Companionable project in awareness context is presented. The system relies on the use of wavelet transform technique for detection and on an unsupervised order estimation of Gaussian mixture model (GMM) arranged in hierarchical form in the aim to improve the recognition...
In this paper, we propose a real-time system for in-home activity monitoring and functional assessment for elder care. We describe the development of the whole system which could be used to assist the independent living of elders and improve the efficiency of elder care practice. With this system, data is collected, silhouettes extracted, features further analyzed and visualized into graphs from which...
In order to clarify the needs of the elderly for ldquoelderly-aimingrdquo products, a questionnaire survey and an experimental study were carried out. A questionnaire survey showed that features which contribute to facilitate use of the essential function of each product were required. In the experimental study, in addition to subjective evaluation of features of an ldquoelderly-aimingrdquo radio,...
Health and mobility of elderly people is gaining importance in aging societies. New communication-based methods to provide health services with personal health care devices are considered promising elements of first-class medical care services for everybody. To achieve this vision, several technological issues have to be solved: (i) body sensors to monitor vital functions have to be developed; (ii)...
