Interaction as exchanged actions and their role in visual and auditory feedbacks
Résumé
This paper aims to point out an underestimated difference between "natural world" as "being given", and "machines" - as "being built"-, focusing on forces as intermediate wield variables to describe interacting complex dynamic systems whose co-evolutions cannot be described "phenomenologically". We will show that to obtain an observable closed-loop system, the relation between human and world have to be supported by a dual input-output paradigm, in which the input (sensors) and outputs (actuators) have to be linked with computational process that necessarily plays the role of a representation of the physical material object. We will then review several case studies that permit to question the shape, image, and sound relations.
