COMMUNICATION BETWEEN A MULTICHANNEL AUDIO ACQUISITION AND AN INFORMATION SYSTEM IN A HEALTH SMART HOME FOR DATA FUSION

International audienceThe Health Integrated Smart Home Information System (HIS²) has been developed in the TIMC laboratory for the remote monitoring of the health status of an elderly person during daily life at home. This aims at improving patients' life conditions and at reducing the costs of the long hospitalization. The design of this system is based on a CAN network linked to volumetric, physiological and environment sensors. In addition, a collaboration between the TIMC and the CLIPS laboratories permitted to replace the video camera, not well accepted by the patients by a system based on a multichannel Sound Acquisition. The coupling between both systems will enable to detect if the person is in a situation of distress or not. Both systems locally processe in real time the incoming data and communicate using a CAN network to display the health status. This article describes the system architecture of both systems, practical solutions for their communication and the evaluation results

ARCHITECTURE ET SIMULATION LOCALES DU SYSTEME D'INFORMATION DOMOTIQUE-SANTE INTEGRE A DOMICILE (SID²) POUR LA DETECTION DE SITUATIONS A RISQUE ET L'AIDE A LA DECISION

M. Jacques Demongeot (Président et Directeur de thèse), M. Norbert Noury (Directeur de thèse), M. André Dittmar (Rapporteur), M. Jean-Pierre Thomesse (Rapporteur), M. Francis Lévi (Examinateur), M. Vincent Rialle (Examinateur)We will begin with a review of Health Smart Homes (HSH) around the world before moving onto a description of our system, the HIS² or "Health Integrated Smart Home Information System", developed at the TIMC laboratory in Grenoble. We hypothesize that there is a connection between biological and social rhythms, behavior, and thus with physical activity which we can measure by observing a subject's displacements within the habitat. We created the term "activity circadian rhythms" (ACR) to refer to the behavioral measurement of patient activity inside the habitat. The HIS² system is made up of an external HIS² connected to the Internet and a local HIS², which is the object of our discussion here. The local HIS², using various types of sensors, is designed to monitor and, though the ACR calculations, self-learn the daily habits of a patient within the HIS², and thus to detect abnormal evolution of the patient's behavior over the long term. A simulation software has been developed to validate the system.Après un tour du monde des Habitats Intelligents pour la Santé (HIS), nous décrivons la mise en place du système grenoblois développé au laboratoire TIMC : le Système d'Information Domotique-Santé Intégré à Domicile (SID²). Nous faisons l'hypothèse que les rythmes biologiques et sociaux sont liés au comportement, et donc à l'activité physique, que nous mesurons par le déplacement du sujet d'observation au sein de l'habitat. Nous créons le terme " Rythmes Circadiens d'Activité " (RCA) pour faire référence à la mesure comportementale de l'activité des patients dans l'habitat. Le système SID² est composé d'un HIS externe relié à Internet, et d'un HIS local, objet de ce document. L'HIS local effectue la surveillance multi-paramétrique et auto-apprend les habitudes de vie d'un patient à domicile à travers le calcul des RCA, de façon à détecter une évolution anormale de son comportement sur le long terme. Un simulateur a été développé pour valider le système

New trends in health smart homes

International audienceThe concept of health smart house aims at giving an autonomous life, in their own home, to people who would normally be placed in institutions: patients suffering from chronic diseases, handicapped people, but also fragile elderly. This article proposes an overview of the research on the concept. It then presents the main trends in each the technological fields of concern -- information systems, home automations, ubiquitous sensors, robotic assistance -- it indicates the standardisation efforts lead by some large consortiums, and the ethical point of view

Cervicocephalic relocation test: a study of performance stability

Objective: The purpose of the present experiment is to determine the reliability of the cervicocephalic relocation test (CRT). Methodology: Thirteen young healthy adults were recruited to perform a CRT test-retest. The test-retest reliability was determined by repeatedly measuring cervicocephalic relocation to a neutral position after active movement, with trials approximately one hour apart. Each CRT involved 20 cervicocephalic relocations to a natural head position, 10 repositioning after right head rotation, 10 repositioning after left head rotation (with the order of rotation side s randomized). The performance of each subject for each CRT was the mean of the errors made during the 20 relocations (in degrees). Study Results: The mean rate of error of the first and second trials were respectively 3.2±1.1° and 2.9±0.9°. The Intra Class Correlation (ICC) coefficient was .81, and the standard error of measurement was .90°. Conclusion: Results show that CRT testing supports evidence of reliable cervicocephalic performance stability in healthy young adults. As a result, CRT shows promise as a relevant tool of assessment in head and neck proprioception
