This paper assesses the motor activity and the relationships between activity measures using the system. The motor activity data (in bed, getting up, getting out, visiting the toilets) are analysed from a statistical perspective to assess changes in occurrence, time and duration. Changes in activity data and correlations between in-bed restlessness and getting up variables show interesting trends in the behavior of elderly people and can be used by the system as a predictive tool in abnormal situations. The objective of the telecare project is to build an abnormal event diagnosis system to help elderly people living alone.

It is designed to monitor these people so as to bring them more security and safety without disturbing their life. The living habits and behaviour of the elderly are recorded with the multisensor system. Artificial neural networks (ANNs) are used to learn the habits of this group of people, thus any behavioural change can be diagnosed. The multisensor system along with the ANN methodology used for learning and some system functionalities are described. Results of habits learning are also given

It is related to a telemedicine system type, remote monitoring or follow-up systems. Patients with chronic diseases or elderly (or handicapped) people are the main target for such systems and we aim at preventing accidents or aggravation of the health status of the concerned patients. After an introduction to telemedicine, our goals and the state of the art, we focus on our own results on architecture, functionalities and enhancements of such a system. We present ...

Instead of hospitalization or institutionalization, the elderly and disabled can be assisted in their own environment 24h a day with numerous 'smart' devices. The concept of the smart home is a promising and cost-effective way of improving home care for the elderly and the disabled in a non-obtrusive way, allowing greater independence, maintaining good health and preventing social isolation. Smart homes are equipped with sensors, actuators, and/or biomedical monitors. The devices operate in a network connected to a remote centre for data collection and processing. The remote centre diagnoses the ongoing situation and initiates assistance procedures as required. The technology can be extended to wearable and in vivo implantable devices to monitor people 24h a day both inside and outside the house. This review describes a selection of projects in developed countries on smart homes examining the various technologies available. Advantages and disadvantages, as well as the impact on modern society, are discussed. Finally, future perspectives on smart homes as part of a home-based health care network are presented.
