Facial action coding captures revealed consumer emotion moment by moment.

Based on Paul Ekman’s foundational work on the universal expression of basic emotions, facial coding has become both a darling of popular media and of serious scientific investigation and advancement.
Facial action coding can be completed by hand from experts trained in the FACS system, or it can be completed by automated systems. While hand coding by FACS experts is more precise, automated facial coding algorithms hold distinct advantages in scalability.
