The model proposed in 1.1.1 has the advantage of providing the
basic, isolated concepts. However, it should be noted that the proposed
schematism obscures the fact that perception and motor control in the
human are tightly coupled. The clearest example is vision, in which a
coherent internal image of the outside world is reconstructed from a series
of controlled eye movements (saccades) and fixations, directed at details
in the environment. The eye musculature plays an essential role here: The
image would fade within seconds if these muscles were paralyzed. Also,
processes like continuous eye-hand coordination require an intrinsic
Output
Input feedback loop in the human, which shunts the
human-machine main information pathway (figure 1.1 ). This issue
will be exposed in the coming chapters, notably
chapter 4 on Interaction.
