This article begins with a summary of the bases for analogical and digital communication. The authors then present hypotheses for their current research program on the physical and behavioral precursors of access to verbal language in the child. Analyses of the baby’s gaze, vocalization and hand movements are the main aspects studied in this joint research. The emergence of intersubjectivity seems to depend basically on a balance between the processes of intersensorial dismantling and of intrasensory segmentation of the different flows of perception.
