A first step towards an ecosystem meta-model for humancentered design in case of disabled users

Abstract: The involvement of the ecosystem or social environment of the disabled user is considered as very useful and even essential for the human-centered design of assistive technologies. In the era of model-based approaches, the modeling of the ecosystem is therefore to be considered. The first version of a metamodel of ecosystem is proposed. It is illustrated through a first case study. It concerns a project aiming at a communication aid for people with cerebral palsy. A conclusion and research perspectives end this paper.
