Affectiva is an emotion measurement technology company that grew out of MIT’s Media Lab, which has developed a way for computers to recognize human emotions based on facial cues or physiological responses. Among the commercial applications, this emotion recognition technology is used to help brands improve their advertising and marketing messages.
Affectiva’s technology can enable applications to use a webcam to track a user’s smirks, smiles, frowns and furrows, which measures the user’s levels of surprise, amusement or confusion.
The technology also allows a person’s heart rate to be measured from a webcam without the person wearing anything. This is done using color changes in the person’s face, which pulse each time the heart beats
