Key Concept - The two key facial cues for recognizing a frown are the steep angle and lowered position of the inner eyebrows.
What is the FROWN Threshold?
Figures 1 & 2: The face transforms from neutral to angry when the inner eyebrows lower significantly at a pronounced angle.
Frowns are a key pose of animated characters, and appear at some point in virtually every feature film, when anger or irritation is expressed. It’s worthwhile to examine the two key elements that make the human frown happen: the position of the eyebrow, and the angle of the upper edge of the inner brow. If either is not playing its required role, the frown vaporizes, and the effect of annoyance or anger (or concentration) vanishes.
The Frown Threshold
From Anger to Rage
Lowered Eyebrow with NO ANGLE = No Frown
Angled Eyebrow but TOO HIGH = No Frown
