Recommandations ergonomiques pour la conception de systèmes d'assistance cognitive dans les habitats intelligents

Cognitive assistance systems are aimed to support people loosing their autonomy while completing activities of daily living (ADL). The range of activities to support, the dissemination of interactive devices in the environment and the variability of users' cognitive capacities raise real challenges when designing assistance in such systems. This paper addresses the assistance issues and presents guidelines for assistive systems design. Especially, based on an experiment of the assistance provided while completing ADL, we suggest a principle of scaled assistance. The principle was applied to Archipel, a cognitive orthesis. This application and the results analysis of a 12 sujects experiment led to the evaluation and the improvement of some ergonomic guidelines about ambient assisted living.
