"Only have EYES
for You!"
THE KEY CONCEPT : When designing characters with only their eyes visible, their most successful range of expressions is limited to Anger and Sadness.

Figures 1, 2 & 3. What do these 3 stylized characters have in common? They are limited to their eyes alone to express their emotional state. The robot’s expression is highly ambiguous; Spiderman’s obliquely-shaped eye opening appears aggressive; Eve’s expression of Joy, missing her mouth, is handicapped without the addition of body language and sound.
 |  ANGRY EYES - Easy to Read Alone Figures 4. There is no question that this is an angry man with exposed teeth, flared nostrils and scowling eyebrows. Figure 5. With only the eye area visible, the expression of Anger can be clearly discerned. |
 |  HAPPY EYES - Harder to Read Alone Figures 6. This man shows all the signs of being happy - his open-mouthed smile, his dimple creases in his full cheeks, his compressed lower eye lids and his narrowed eyes all say "Joy." Figure 7. Without the other facial clues, the eyes alone are difficult to read unambiguously as "Joy." |
100% of online respondents agreed that my drawing of Joy (Figure 6) looked happy, and a similar percentage thought my drawing of Anger (Figure 4) looked angry. However, when masking the lower half of the face, the number of people who still saw the happy face as joyful (Figure 7) dropped by over 50% (I’m a bit surprised it wasn’t more), while 94% of the testers still saw Anger in just the upper half of the face (Figure 5).
This was consistent with our previous tests. Joy requires a visible mouth – the smile – to be clearly readable while angry eyes are quite clear without seeing the mouth at all.
This is good news for animators creating characters like Iron Man and Spider-Man (Figure 2), whose masks present permanently scowling eyes, and hide the mouth. We get the message from just the narrowed eye shape that these are men to be reckoned with, ready for a fight.
It’s bad news, however, for robot designers hoping to create empathetic machine companions without an expressive mouth. While it is – barely – possible to create a sense of a happy, friendly character with just smiling eyes, it requires the sort of sounds and body language that Eve presented in Wall-E. The laughing Eve (Figure 3), besides making the right noises, also bounced up and down, and brought one “hand” up to her non-existent mouth. We are so programmed to look for a mouth to determine happiness that it’s a great deal of work to accomplish the same thing with the mouth missing.
If your character needs to express Anger or Sadness, the eyes alone can do the trick. The opposite is true of Joy – the mouth alone, characterized by a big smile, can carry the message.
