Because Actions Speak louder than words
The Facial Action Coding System (FACS) is a globally recognized, sophisticated research instrument that exactly measures the whole range of human facial expressions. FACS has elucidated the physiological existence of emotion with very high levels of dependability. In fact, it has envisaged patterns related to deception at about 80% accuracy.
Emotional expression exceeds the barriers of race, ethnicity, culture, gender, religion and age. Despite of surroundings, humans express facial emotions in precisely the same way. The aptitude to read emotional behavior is a crucial constituent of effective communication. FACS exploits these concepts to give advantage to those who perform interviews, interrogations and business transactions as well as those involved in law enforcement, security and the legal and healthcare systems.
Created in the 1970s by psychologists Paul Ekman and Wallace V. Friesen; FACS offers a complete nomenclature of human facial expressions. FACS stays the most extensively used and highly praised method for coding the minutest movements of the human face.
