This paper addresses the issue of the evaluation of technological devices for digital accessibility for people with disabilities or loss of autonomy. It builds on the work of a multidisciplinary consortium that has been set up at the national level to develop and propose a multidimensional evaluation and observation methodology based on an integrative co-design approach. The main qualitative and quantitative methods used by the partners in the field of digital accessibility are presented. Crossing the two methods from use contexts is essential to model and qualify behaviours in digital accessibility. The implementation of the methodology is illustrated by a pre-study on five volunteers in a smart home environment.
