The Facial Action Coding System, (FACS), devised by Ekman and Friesen (1978), provides an objective meanS for measuring the facial muscle contractions involved in a facial expression. In this paper, we approach automated facial expression analysis by detecting and classifying facial actions. We generated a database of over 1100. Paul Ekman was born to Jewish parents in 1934.

Facial expression is widely used to evaluate emotional impairment in neuropsychiatric disorders. Unlike facial expression ratings based on categorization of expressions into prototypical emotions happiness, sadness, anger, fear, disgust, etc. However, FACS rating requires extensive training, and is time consuming and subjective thus prone to bias.
Paul Ekman
The Facial Action Coding System FACS is an internationally recognized, sophisticated research tool that precisely measures the entire spectrum of human facial expressions. FACS has elucidated the physiological presence of emotion with very high levels of reliability. Created in the s by psychologists Paul Ekman and Wallace V. Friesen FACS provides a comprehensive taxonomy of human facial expressions. FACS remains the most widely used and acclaimed method for coding the minutest movements of the human face. The system dissects observed expressions by determining how facial muscle contractions alter appearance.
Traditionally a manual coding system , which quantifies all possible movements a person can make with his or her face. Recent advances in computer vision have allowed for reliable automated facial action coding. Below you can see the 20 Action Units offered in the most recent version of FaceReader as well as some frequently occurring or difficult action unit combinations. Some images have been zoomed in on the area of interest to explicitly show what muscle movement corresponds to the specific Facial Action Unit. Traditionally a very time-consuming task, reliable action unit coding is automated using FaceReader. Contributes to the emotions sadness, surprise, and fear, and to the affective attitude interest. Muscular basis: frontalis pars medialis.
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. Researchers have for a long time been limited to manually coding video recordings of participants according to the action units described by the FACS.

New facial expressions uncovered
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. The Paul Ekman Group offers the manual for sale.

Facial Action Coding System
Facial Action Coding System Facial Action Coding System (FACS) is a system to taxonomize human facial movements by their appearance on the face, based on a system originally developed by a Swedish anatomist named Carl-Herman Hjortsjö.[1] It was later adopted by Paul Ekman and Wallace V. Friesen, and published in 1978.[2] Ekman, Friesen, and Joseph C. Hager published a significant update to FACS in 2002.[3] Movements of individual facial muscles are encoded by FACS from slight different instant changes Muscles of head and neck. [] in facial appearance. It is a common standard to systematically categorize the physical expression of emotions, and it has proven useful to psychologists and to animators. Due to subjectivity and time consumption issues, FACS has been established as a computed automated system that detects faces in videos, extracts the geometrical features of the faces, and then produces temporal profiles of each facial movement.[]
Uses Using FACS,[4] human coders can manually code nearly any anatomically possible facial expression, deconstructing it into the specific Action Units (AU) and their temporal segments that produced the expression. As AUs are independent of any interpretation, they can be used for any higher order decision making process including recognition of basic emotions, or pre-programmed commands for an ambient intelligent environment. The FACS Manual is over 500 pages in length and provides the AUs, as well as Ekman’s interpretation of their meaning. FACS defines AUs, which are a contraction or relaxation of one or more muscles. It also defines a number of Action Descriptors, which differ from AUs in that the authors of FACS have not specified the muscular basis for the action and have not distinguished specific behaviors as precisely as they have for the AUs. For example, FACS can be used to distinguish two types of smiles as follows:[] • Insincere and voluntary Pan-Am smile: contraction of zygomatic major alone • Sincere and involuntary Duchenne smile: contraction of zygomatic major and inferior part of orbicularis oculi. Although the labeling of expressions currently requires trained experts, researchers have had some success in using computers to automatically identify FACS codes, and thus quickly identify emotions.[5] Computer graphical face models, such as CANDIDE [6] or Artnatomy [7], allow expressions to be artificially posed by setting the desired action units. The use of FACS has been proposed for use in the analysis of depression,[] and the measurement of pain in patients unable to express themselves verbally.[] FACS is designed to be self-instructional. People can learn the technique from a number of sources including manuals and workshops,[8] and obtain certification through testing.[9] A variant of FACS has been developed to analyze facial expressions in chimpanzees.[] FACS can also be modified such that it can be used to compare facial repertoires across similar species, such as humans and chimpanzees. A study conducted by Vick and others (2006) suggests that FACS can be modified by taking differences in underlying morphology into account. Such considerations enable a comparison of the FACS

present in humans and chimpanzees, to show that the facial expressions of both species result from extremely notable appearance changes. A cross-species analysis of facial expressions can help to answer the question of which emotions are uniquely human.[10] EMFACS (Emotional Facial Action Coding System)[11] and FACSAID (Facial Action Coding System Affect Interpretation Dictionary)[12] consider only emotion-related facial actions.

Codes for Action Units For clarification, FACS is an index of facial expressions, but does not actually provide any bio-mechanical information about the degree of muscle activation. Though muscle activation is not part of FACS, the main muscles involved in the facial expression have been added here for the benefit of the reader. Action Units (AUs) are the fundamental actions of individual muscles or groups of muscles. Action Descriptors (ADs) are unitary movements that may involve the actions of several muscle groups (e.g., a forward‐thrusting movement of the jaw). The muscular basis for these actions hasn’t been specified and specific behaviors haven’t been distinguished as precisely as for the AUs. For most accurate annotation, FACS suggests agreement from at least two independent certified FACS encoders.
Intensity Scoring Intensities of FACS are annotated by appending letters A–E (for minimal-maximial intensity) to the Action Unit number (e.g. AU 1A is the weakest trace of AU 1 and AU 1E is the maximum intensity possible for the individual person). • • • • •
