History In 1872. Charles Darwin published a book “The Expression of the Emotions in Man and Animals”. He compared numerous images of humans and animals in different emotional states and suggested that some basic emotions, like anger, fear and sadness, are universal and present across ethnicities, cultures and even species. According to Darwin facial expressions were inborn (not learned) and common to humans and animals (some human characteristics like clenching teeth in anger or tears in eyes when sad have animal origin).C.

His research showed that Darwin was right and that facial expressions and emotions are universal as people from diverse cultural background interpreted expressions in photos in similar way.

(2003) Technology The computer algorithm for facial coding extracts the main features of face (mouth, eyebrows etc.) and analyzes movement, shape and texture composition of these regions to identify facial action units. Therefore, it is possible to track tiny movements of facial muscles in individuals’ face and translate them into universal facial expressions that convey happiness, surprise, sadness, anger and others. Algorithm developed by EyeSee can detect following 7 emotions: happiness, surprise, puzzle, disgust, fear, sadness and neutral.
