The first session, containing 13 images, includes the neutral expression, smile, anger, screaming, different lighting changes, and two realistic partial occlusions with lighting changes.

If you've ever heard the expression "Smile with your eyes," there's science to back it up.
Emotion manifests itself in various ways, through changes in facial expression, smiling, sneering, crying, blushing, and so on, but also in complex behaviors like shouting, running away, hugging or lashing out.
Within-subject factors were face expression (smiling or angry), success feedback (won or lost), and screen area (face or word).
The study had a 3 (emoticon expression: smiling vs. frowning vs. no emoticon) × 3 (colour label: red vs. green vs. white) × 2 (snack bar type: chocolate bar vs. cereal bar) between-subjects design.
In a 3 (emoticon expression: smiling vs. frowning vs. no emoticon) × 3 (colour label: green vs. red vs. white) ×2 (food option: chocolate bar vs. cereal bar) between-subjects experiment, participants rated the level of desirability, healthiness, tastiness, and calorific content of a snack bar they had been randomised to view.
A 3 (emoticon expression: smiling vs. frowning vs. no emoticon) × 3 (colour label: green vs. red vs. white) × 2 (snack bar type: chocolate bar vs. cereal bar) between participants' ANOVA on ratings of calories yielded no significant main effects or interactions, all Fs < .54.54
You can designate which of up to eight people in the viewfinder to focus on, and select three different facial expressions: smile, grin or laugh.Even so, this is still a long way from proper face recognition.
The use of informal wording and emoji, including virtual facial expressions (smile, sign, sweat, and so on), could greatly soften the tone of the request and create a casual, friendly, and relaxed atmosphere for conducting the survey.
A smile is a universally understood facial expression smile often, and you'll show everyone you have good intentions.
