"Our faces are organs of emotional communication; by some estimates, we transmit more data with our expressions than with what we say," says Raffi Khatchadourian in his article We Know How You Feel. Pioneers in the emotional communication space include Emotient, Realeyes, Sension, and Affectiva. All are competing to create emotionally responsive machines dedicated to decoding the human face, a notoriously difficult subject, who essence is rarely captured, even by the world's greatest artist.

In his article, Raffi Khatchadourian profiles Affectiva, a startup specializing in cutting-edge AI technologies that applies machine learning, deep learning, and data science to emotional intelligence.
