Facial expressions are a strong visual method to convey emotions. 3D Facial Imaging directly records human emotions from facial expressions to better measure consumer response to marketing stimuli (e.g. advertising, packaging, retail displays). This presentation shows how an automated, artificial intelligence based system of facial imaging can be integrated into an online panel in a manner complementing traditional survey based approaches. This produces new insight on both how people answer conventional questions and how to exploit more efficient ways of gathering accurate responses to complex marketing questions.
