Service Reconfiguration in the DANAH Assistive System
International audienceSmart Homes are pervasive systems that interact with the user using a service offer paradigm to provide fully automated daily repetitive tasks. When services are augmented with semantic relationships, one can build adaptive services and systems. In this paper we deal with service failures and propose a recovering method, which we call service reconfiguration, to ensure service availability in smart homes. Both off-line and on-line reconfigurations are considered. This method has been implemented in the DANAH assistive system
Multi-Level ReconïŹguration in the DANAH Assistive System
International audienceNowadays, interaction with our surrounding environment has increased due to the presence of numerous devices that provide us with services. This is especially true in Smart Homes and can be of great help for the disabled people and the elderly that can no longer perform daily tasks they used to. However, in case of failure, corrective actions can be heavy to take, thus the need for the system to recover by itself and ensure service availability. Service availability is provided through service reconïŹguration. This papers deals with service reconïŹguration in smart homes. It presents a multi-level approach in which both off-line and on-line reconïŹguration schemes are used to gradually recover from failed services. Static, effect-based, path and resource reconïŹguration levels are described. They have been successfully implemented in the DANAH assistive system, which combines both navigation and service provision for smart homes
Architecture and models of the DANAH assistive system
International audienceIn this paper we present DANAH, an assistive system under development at the Lab-STICC laboratory at the European University of Brittany, in collaboration with the Kerpape center for functional reeducation and readaptation in Lorient. DANAH aims to be an almost all-in-one assistive system (ATS) which combines existing technologies to deliver suitable assistance for the disabled and the elderly. It focuses on both environmental control as well as navigation to help the physically impaired to perform everyday tasks and maintain a reasonable level of autonomy. Moreover, rapid prototyping methods have been introduced to speed up development, reduce costs and enforce ATS adoption
Vers une approche orientĂ©e services pour lâaide au handicap
Ce papier sâintĂ©resse Ă la construction dâun systĂšme dâaide au handicap et de maintien des per-sonnes Ă domicile Ă travers deux aspects fondamentaux consistant pour le premier en la modĂ©li-sation de lâespace de vie et pour le deuxiĂšme en la modĂ©lisation de la proposition de services.Lâusager sur fauteuil roulant dans sa maison ou en institut de rĂ©Ă©ducation se voit offrir par le sys-tĂšme les services courants de la vie quotidienne, en sĂ©lectionne un et le systĂšme se charge dâĂ©la-borer un itinĂ©raire correspondant Ă ses besoins, de piloter son fauteuil jusquâĂ destination en enfinactiver les actions nĂ©cessaires Ă lâaccomplissement du service. Notre approche vise aussi bien lespetites structures que les grands centres de soins et par consĂ©quent adopte volontairement unestratĂ©gie rĂ©partie pour le systĂšme dâassistance au handicap. Nous proposons une modĂ©lisationdâespace de vie dĂ©centralisĂ©e rĂ©partie ainsi quâun modĂšle de services tolĂ©rant aux pannes pourassurer une qualitĂ© de service suffisante en plus de mĂ©canismes sĂ©curitĂ© pour les usagers. LesystĂšme ainsi obtenu se distingue des autres travaux antĂ©rieurs du fait de son homogĂ©nĂ©itĂ© etde sa complĂ©tude
