FACS is used across many different personal and professional settings. It is often used in various scientific settings for research. It is also used by animators and computer scientists interested in facial recognition. FACS may also enable greater awareness and sensitivity to subtle facial behaviors. Such skills are useful for psychotherapists, interviewers, and anyone working in communications. It also describes how AUs appear in combinations.

Facial Action Coding System

FACS (Facial Action Coding System)

The Facial Action Coding System FACS is a widely used protocol for recognizing and labeling facial expression by describing the movement of muscles of the face. FACS is used to objectively measure the frequency and intensity of facial expressions without assigning any emotional meaning to those muscle movements. Instead, FACS breaks down facial expressions into their smallest discernable movements called action units. Each action unit creates a distinct change in facial appearance, such as an eyebrow lift or nose wrinkle. FACS coders can identify the action units that are present on the face when viewing still images or videos. Psychological research has used FACS to examine a variety of research questions including social-emotional development, neuropsychiatric disorders, and deception.

A Psychometric Evaluation of the Facial Action Coding System for Assessing Spontaneous Expression

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.
Emotion can be defined as any relatively brief conscious experience characterized by intense mental activity and a high degree of pleasure or displeasure. Scientific discourse has drifted to other meanings and there is no consensus on a single definition. Emotion is often intertwined with mood, temperament, personality, disposition, and motivation. Emotions are multicomponent response tendencies that unfold over relatively short timespans. This appraisal process conscious or unconscious triggers a cascade of response tendencies manifesting across loosely coupled component systems.
