FACS (Facial Action Coding System) Fotoreferenser

collage of Facial Action Coding System action units and AU labels

FACS Photo References is an image library of action units (AUs) and action descriptors (ADs) from the Facial Action Coding System (FACS). All references are performed by the författare, who is FACS-certified with 14 years of experience in facial muscle isolation.

FACS åtgärdsenhet

FACS AU1 - inner brow raiser: neutral vs. frontalis medialis contraction. Expert reference by Melinda Ozel.
AU1 - inner brow raiser is activated by medial frontalis contraction. Note the raise in the central forehead area. Contrary to many literature assertions, inner brow raiser does not need to be perfectly lifted at the innermost brow tips. It often occurs slightly lateral to the brow start.
FACS AU2 - outer brow raiser: neutral vs. frontalis lateralis contraction. Expert reference by Melinda Ozel.
AU2 - outer brow raiser is activated by lateral frontalis contraction. Note that the peak of the raise typically occurs at the arch of the brows, causing the resulting brow shape to appear more angular than a full frontal belly contraction.
FACS AU4 - brow lowerer: neutral vs. mostly corrugator supercilii contraction (in this specific example). Expert reference by Melinda Ozel.
AU4 - brow lowerer is activated by any combination of the following brow lowering muscles: corrugator supercilii, depressor supercilii, and/or procerus. For isolated GIFs of corrugator supercilii and depressor supercilii, click on the image above to view the Facial Muscle Anatomy Function Guide.
FACS AU5 - upper lid raiser: neutral vs. levator palpebrae superioris contraction. Expert reference by Melinda Ozel.
AU5 - upper lid raiser is activated by the contraction of the levator palpebrae superioris muscle and depending on nervous system state, Müller’s (superior tarsal) muscle as well. Note the increased sclera visibility and the decreased distance between the upper eyelid and lower eyebrow border.
AU6 - upphöjning av kinden - Melinda Ozel - Face the FACS
AU7 - Lidt hårdare - Melinda Ozel - Face the FACS - Blendshape - Blendshapes - blend shape - blend shapes - FACS - Facial Action Coding System
AU8 - läpparna mot varandra - brölande mun - blendshape - blendshapes - blend shape - blend shapes - FACS - Facial Action Coding System (system för kodning av ansiktshandlingar)

NOTERA: Jag har tillfälligt tagit bort "Howler Mouth". Jag försöker hitta det bästa sättet att dela upp det så att det inte blir överflödigt med former som "vertikal läppstramare".

AU13 - Skarp läppdragare - levator anguli oris
AU14 -dimpler- buccinator
FACS AU14 - dimpler: neutral vs. posterior buccinator contraction. Expert reference by Melinda Ozel.

NOTERA: Jag har myntat två differentieringar av dimpler-verkan: y-axelns dimpler och Z-axelns dimpler. I have done so because the existing FACS facial actions do not effectively encompass the depth of expression possible to achieve from the buccinator muscle (the muscle driving AU14).

Det finns två typer av dimplers som jag har observerat:

1) y-axelns dimpler – involving outer portions of the lip corners compressing against each other in a vertical plane (superior and inferior buccinator)
2) Z-axelns dimpler – involving the inner mouth portions of the lip corners pushing against the teeth and inner cheeks (posterior buccinator)

AU23 - vertikal läppstramare - orbicularis oris

NOTERA: Vertical lip tightener (which I also refer to as “lip cincher”) is not an official FACS shape. I have coined this action in order to further break down the functional movements of orbicularis oris. Se mer här. These refinements of orbicularis oris actions are critical to applications like lipsync and nuanced expression detailing.

AU24 - läpptryckare - orbicularis oris
AU24 - lip presser involves the pressing of the upper and lower lip against one another from the contraction of the marginal part of orbicularis oris. AU24 may also be referred to as "lip pressOr" depending on which Ekman inconsistency you prefer to follow. In the latest 2002 FACS Manual, AU24 is consistently referred to as "lip pressEr." However, in the 1978 FACS Investigator's Guide, and in Ekman's subsequent writings (e.g. in Vad ansiktet avslöjar), it is referred to as "lip pressOr." Looks like we will have to wait until the next release of the FACS-manual to settle this pressning fråga.
