During this presentation, I will give you a short overview of the enactive paradigm origin - the work of Francisco Varela and Humberto Maturana - to position it within the field of embodied cognition. Then, I will present different studies in neuroscience and psychology that are in line with this paradigm. The second part of my presentation will focus on the implications of this paradigm for research in computer science. There are two orientations : the first one is on artificial intelligence or artificial life, in particular, the enactive field could provide directions for developmental approaches. The second one is on interactive systems. The enactive paradigm could help us design interactive systems that are better coupled with Humans to favor an enactive loop and then increase the relevance of technological progress. I will illustrate these points with some examples from my research group at Brest, France
