Introduction

According to our research program, in the next two to five years, we will study dynamics of interaction along three levels depending on interaction time scale and related user's perception and behavior: Micro-dynamics, Meso-dynamics, and Macro-dynamics. Considering phenomena that occur at each of these levels as well as their relationships will help us to acquire the necessary knowledge (Empowering Tools) and technological bricks (Interaction Machine) to reconcile the way interactive systems are designed and engineered with human abilities. Our strategy is to investigate issues and address challenges for all of the three levels of dynamics. Last year we focused on micro-dynamics since it concerns very fundamental knowledge about interaction and relates to very low-level parts of interactive systems. In 2019 we were able to build upon those results (micro), but also to enlarge the scope of our studies within larger interaction time scales, especially at the meso-dynamic level. Some of these results have also contributed to our objective of defining the basic principles of an Interaction Machine.
