Setup of a study using motion tracking to investigate continuous properties of evolving manual signals. Panel a: Seed gestures for a fixed set of meanings are learned by next generations in an iterative learning experiment. Panel b: Using motion tracking, we derive automatic kinematic measures of entropy, temporal variability and intermittency over time and over generations.
