Non-contact emotion detection
Non-contact emotion detection, analyzing eyebrows, eyes, mouth movements and micromovements allows to detect a wide range of emotions and feelings. In the last decades a handful of universal facial expressions have been recognized. Not all facial expressions stick around for a long time. Those that pass quickly are called micro-expressions and are almost indiscernible to the casual observer.

- Emotion analysis: analyse and extract emotional stat of a person on the head’s vibrational parameters
Facial micromovements
The set of tools to detect emotions
EVM (Eulerian Video Magnification)
- Amplify subtle Facial Movements
Finder
- Extracts face significant points
FM Analyser
- Extracts facial micromovements using DOF (Dense Optical Flow) and other algorithms
- Facial micromovements carry specific nonverbal information, for example the facial movement caused by pain
