Facial expressions are tracked in real time using key points on the viewer’s face to recognize a rich array of both emotional and cognitive states such as enjoyment, attention and confusion. Many of the users’ responses are so quick and fleeting that viewers may not even remember them, let alone be able to objectively report about them.
A facial expression database is a collection of images or video clips with facial expressions of a range of emotions. Well-annotated ( emotion -tagged) media content of facial behavior is essential for training, testing, and validation of algorithms for the development of expression recognition systems .
Real-time face detection in video footage became possible in 2001 with the Viola–Jones object detection framework for faces. [28] Paul Viola and Michael Jones combined their face detection method with the Haar-like feature approach to object recognition in digital images to launch AdaBoost, the first real-time frontal-view face detector.

The face expresses a great deal of emotion, however, there are two main facial muscle groups that are usually studied to detect emotion: The corrugator supercilii muscle, also known as the 'frowning' muscle, draws the brow down into a frown, and therefore is the best test for negative, unpleasant emotional response.↵The zygomaticus major ...
The AI uses an optical sensor like a webcam or smartphone camera to identify a human face in real-time. [17] Then, computer vision algorithms identify key features on the face, which are analyzed by deep learning algorithms to classify facial expressions. These facial expressions are then mapped back to emotions.
The 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]
Affective computing can be used to measure and to recognize emotional information in systems and devises employing affective haptics. Emotional information is extracted by using such techniques as speech recognition, natural language processing, facial expression detection, and measurement of physiological data.
