[Perception and regulation of human movement: Plea for a physical biology].
This article analyzes the circular causality existing between movements and their perceptual consequences. The interaction between the observer and the environment gives rise to multiple energy changes (e.g., optical, inertial), which contain a lot of information relevant for its control. Based on a formal analysis of the energy flows and the physical constraints organizing human motor acts, exemplary control laws are described governing the online guidance of our daily gestures. The efficiency of the sensori-motor mechanisms observed in the regulation of walking, reaching, and bouncing is emphasized.
