The social dimension of sustainability seems to have been a notion rarely addressed in the literature (Dubois et al., 2001) until the early 2000s. The EUTIC 2023 symposium provides an opportunity to take up this topical issue. To this end, we are presenting an engagement process that is part of a sustainable development dynamic, based on digital tools inspired by everyday life, for applications in the context of training, with a view to lifelong learning. Our work, which stems from the information and communication sciences, is rooted in a multi-disciplinary approach that we believe can be echoed in a variety of disciplines, but which it is interesting to challenge, hence the purpose of this contribution.
