This article aims to revisit and to adapt the Norman's theory of action by focusing on the design of interactive systems for disabled people. The background section demonstrates that there is a need to include all the stakeholders involved in the environment of the disabled person in the design process, constituting his or her ecosystem. Then the adaptation of the Norman's theory action, considering explicitly the ecosystem is justified; examples of the both role of the disabled people and members of his/her ecosystem are given for the seven components of Norman's model. Two cases studies are after presented to illustrate the crucial role of the ecosystem in case of assistive interactive system design. The benefits of taking into account the ecosystem in the design of interactive systems for disabled persons are discussed. The article ends with a conclusion and research perspectives.
International audiencehis paper presents on-going research concerning the design of monitoring features for human-computer interfaces (HCI) for long distance training courses. The objective is to design visualization tools that facilitate the task of the on-line course teacher. The teacher needs to see the learning path and learners contributions in the Learning Management System (LMS). The paper successively presents the research issues related to computer design of such interfaces, a typology of different dimensions to be taken into account (scenario, participants, calendar) and a tool designed for on-line monitoring of individual paths inside a training course (CROISIÈRES). Perspectives concern a methodological framework for HCI design and evaluation in the context of supervisory control in distance course
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
