Cooperative model generation for disabled people assistance

This article presents a communication architecture of hadicap technical assistance system in a multi users context. The proposed services are available in some particular areas only, for that, the environment is split into several areas and sub-areas, and services are associated to some area. Because many people live in this environment, we propose to assign for each area one manager and for each door in the living space one controller in order to guaranty availability of services (domotic services and navigation assistance). A dialogue protocol allowing the cooperation between users and their environment is defined and an enrichment sub-procedure is used to get a cooperation path model for each intelligent wheelchair.
