CIRDO: Smart companion for helping elderly to live at home for longer

8 pagesInternational audienceCirdo project is intended to establish new healthcare systems to ensure the safety at home of seniors and people with decreasing independence. In particular, extending "e-lio" (http://www.technosens.fr/) device, Cirdo aims to develop an audio/video-based system which makes it possible for elderly to live with a sufficient degree of autonomy. To achieve this goal, generic purposes on video analysis and audio processing are discussed and implemented in the same process. Audio and video analysis algorithms are launched simultaneously and thinks to GPU implementation, the tasks are done in real time. To comply with the requirements set out in the Cirdo project namely: respect privacy and preserve personal data, the processing tasks is performed through background tasks, without any human intrusion. In order to have different types of fall for our experiences, multiple scenarios were designed and performed by several persons. Besides the technical aspect, the project also focuses on generic technology validation by potential users and their human environment (family, caregivers/care takers...). Psychological and ergonomic assessment on the use of services developed was conducted. It focused on the usefulness, usability and accessibility and acceptance of the tool. This evaluation was completed by critical investigation of knowledge acquired by professionals (geriatricians, caregivers school and associations)

TIC et conditions de travail des cadres. Une formation-action avec des syndicalistes européens

Les technologies de l’information et de la communication se déploient massivement dans toutes les fonctions et dans les secteurs des organisations. Elles transforment profondément l’activité des salariés, en particulier celle des cadres. Dans ce contexte, les représentants syndicaux sont conscients des questions et des enjeux posés par l’usage de ces outils. Cependant, il n’est pas toujours évident de déterminer clairement quels types de revendications proposer et à quels niveaux il est nécessaire d’agir. Eurocadres a lancé une réflexion à ce sujet, en s’appuyant à la fois sur les apports de chercheurs experts de ce domaine et sur l’expérience des représentants syndicaux pour pouvoir avancer sur ces questions. Cet article s’appuie sur les réflexions de responsables syndicaux de l’encadrement européens recueillies lors d’une formation-action animée par des enseignants-chercheurs du laboratoire GRePS (rubrique « Etude »)

The user-centered design of an ambient technology for preventing falls at home

Purpose: In the context of the elderly homecare, an innovative and pervasive solution2, consisting of a camera and a microphone, is being conceptualized (ANR & CNSA project). This system called CIRDO is based on an intelligent and systematic analysis of the audio and visual environment of the elderly. It could detect risk situations (falls) and therefore give the emergency alert.Method The design of the device is based on two levels of analysis. The first is to identify and characterize the falling process5 in order to provide system designers with a set of behavioral (key breaks) and verbal (keywords) descriptors (or indicators) required for setting up CIRDO. To do this, various methods have been deployed: semi -structured interviews with 65 aged people, analysis of daily life activities conducted at seniors homes, analysis and falls’ script methods (simulation, filmed incidents observations and Personas method1). The second one was to explore the social acceptance of this new technology into the social systems of the elderly (composed by the person themselves, their family environment, professional and personal caregivers) by interviewing a sample of 62 people (24 elderly,19 family caregivers and 19 professional caregivers) through a process of triangulation methods (semi-structured interviews, focus groups and activity analyses).Results & Discussion From the first set of data, 12 scripts of falls have been elaborated (Fig 1). In a second part, the social acceptance of the future device has been tackled, taking into account the experiences and positions of the various actors confronted to the device. The reading grid offered by Engeström's system of activity3 has shown an ambivalent positioning by these different actors: based on their experiences, their career and needs, each of them (elderly, professional counselors, family) has a different view of the object of their activity (support, help, care, prevention, control), and therefore has specific expectations and fears. The function and purpose of the device are (implicitly) heterogeneous because interpreted differently by the various stakeholders (Fig 2): visions that may be incomplete, conflicting or partially contradictory. The difficulty in the design and implementation of CIRDO is to adjust to a psycho-socio, home embedded system that is different every time given (i) the diversity of activities at risk of the elderly, and (ii) the interests of different actors

Concevoir une technologie pervasive pour le maintien à domicile : une démarche prospective par la prise en compte des systèmes d'activité

International audienceThis paper presents a prospective ergonomic approach that allows us to evaluate a new pervasive technology (CIRDO) for the home care of dependent elderly persons. The aim of this technology is to empower these persons by the detection of their physical falls (via audio and video sensors) and to alert their family or care givers. In light of the ac-tivity theory model, we developed a prospective approach in the real environment of the elderly that aims to help us to reflect upon the conception and design of future things and to understand the way in which each person in the system could benefit from such a contrivance. In order to understand these effects, we developed a methodological trian-gulation approach by involving various techniques of data collection such as semi-structured interviews, focus group, analysis of the activities of daily living conducted at seniors homes, script falls methods, simulation of incidents by the elderly, observations filmed with simultaneous verbalization techniques and Personas method, We show that the implementation of CIRDO has an impact on the activity of each person in the home (elderly persons, family, professional care-givers) and could also redefine the relation-ships between different systems of activity, requiring each participant to adjust and re-position his practice, status and commitment in the area of habitation. In this context, our contribution is not only to imagine the uses, but also to explore the social function associated with this new tool.Cet article présente une démarche psycho-ergonomique à orientation prospective visant à évaluer l’intégration d’un environnement pervasif de téléassistance (CIRDO) dans le milieu de vie des personnes âgées dépendantes maintenues à domicile. L’objectif de cet environnement est de favoriser l’autonomie de ces personnes en détectant automatiquement les chutes (via des capteurs audio et vidéo) et le cas échéant d’alerter l’entourage. A partir du modèle des systèmes d’activité, nous proposons une démarche prospective en situation réelle de vie qui vise à prévoir ces usages et à évaluer la manière dont chaque acteur du domicile se saisit du futur système. Nous montrons que la mise du œuvre du dispositif peut avoir des incidences sur les systèmes d’activité de chaque acteur en présence (personne âgée, famille, aidant professionnel) et qu’il peut également redéfinir les relations entre ces différents Systèmes d’activité, obligeant chaque protagoniste à repositionner ses pratiques, son statut et son engagementdans la sphère de l’habitat. Dans ce cadre, notre apport consiste non seulement à imaginer les usages, mais également à prospecter la fonction sociale associée à ce nouvel outil
