![]() ![]() Then we used the proposed AUs to make tongue animation for a very popular tongue movement in Egypt which is called Zaghrouta. The results were very analogous to the ones performed by the real humans. and compared the results with photos that have been captured for real humans performing the proposed AUs. We applied these AUs on a 3D human model using Daz Studio Pro. In this paper, we proposed 12 AUs (Action Units) for the Tongue, based on tongue anatomy, following the same format Paul Ekman used in defining FACS AUs. That limits FACS from being the dominant technique in the Facial Animation field. FACS provides a very reliable description for the face upper parts but it does not for the lower parts of the face. FACS (Facial Action Coding System) is an anatomically based system for describing all observable facial movements.
