New data released by emotion AI company Realeyes, used webcams and its face-reading technology to rank this year’s Super Bowl ads based on how much attention and emotional engagement they generated from viewers.
No where in this article do they mention a focus / study group for this purpose, only webcams and social media. Curious !
Ad was funny though
