Résumé

We present a gaze stabilization system using only visual information as feedback for a self tuning dynamical system. We describe how the dynamical system tunes its internal parameters to those of the optical ﬂow information to generate compensatory commands. We show that the system can be applied to head stabilization during periodic locomotion, but also to tracking periodically moving objects.

Système visuel humain

Le est l'ensemble des organes participant à la perception visuelle humaine, de la rétine au système sensori-moteur. Son rôle est de percevoir et d'interpréter deux images en deux dimensions en une image en trois dimensions. Il est principalement constitué de l'œil (et plus particulièrement la rétine), des nerfs optiques, du chiasma optique, du tractus optique, du corps genouillé latéral, des radiations optiques et du cortex visuel. En première approximation, l'œil peut être assimilé à un appareil photographique.

Musical tuning

In music, there are two common meanings for tuning: Tuning practice, the act of tuning an instrument or voice. Tuning systems, the various systems of pitches used to tune an instrument, and their theoretical bases. Tuning is the process of adjusting the pitch of one or many tones from musical instruments to establish typical intervals between these tones. Tuning is usually based on a fixed reference, such as A = 440 Hz. The term "out of tune" refers to a pitch/tone that is either too high (sharp) or too low (flat) in relation to a given reference pitch.

Dynamic tonality

Dynamic tonality is a paradigm for tuning and timbre which generalizes the special relationship between just intonation and the harmonic series to apply to a wider set of pseudo-just tunings and related pseudo-harmonic timbres. The main limitation of Dynamic Tonality is that it is best used with compatible isomorphic keyboard instruments and compatible synthesizers or with voices and instruments whose sounds are transformed in real time via compatible digital tools.
