Facial Action Coding System (FACS) – A Visual Guidebook

Facial Action Coding System - Wikipedia

The FACS as we know it today was first published in , but was substantially updated in Using FACS, we are able to determine the displayed emotion of a participant. This analysis of facial expressions is one of very few techniques available for assessing emotions in real-time fEMG is another option. Other measures, such as interviews and psychometric tests, must be completed after a stimulus has been presented.

Facial action coding system (FACS)

Inner Brow Raiser. Frontalis, pars medialis. Corrugator supercilii, Depressor supercilii. Orbicularis oculi, pars orbitalis.
Many researchers code muscle movements to learn more about how and why the face moves. They use the Facial Action Coding System which provides them with a technique for the reliable coding and analysis of facial movements and expressions. They indicate which AUs moved to produce the changes observed in the face. This makes FACS coding quite objective. In scoring, it will be necessary to apply slow motion and frame-by-frame viewing to identify the AUs that occur, always alternating with real time viewing.
