This paper presents the topics and the activity of the theme E “disabilities: analysis models and tools” within the GDR STIC Santé. This group has organized a conference and a workshop during the period 2011–2012. The conference has focused on technologies for cognitive, sensory and motor impairments, assessment and use study of assistive technologies, user centered method design and the place of ethics in these research topics. The objective of “bodily integration of technique” workshop, organized in the framework of Défi Sens (CNRS) was to develop a multidisciplinary approach (physiology, robotics and anthropology) of the relationships between body and technology taking as an example the prostheses for the compensation of sensorimotor disabilities. Efforts will focus on strengthening the development of a multidisciplinary research for the design of assistive technologies for elderly people and people with disabilities. The modelling of the user’s abilities and the designing of adaptable AT to the needs of the person will be carried out with other groups of this GDR and also with other GDRs.
