As a selfie freak, I always feel there’s something missing in my smile. And it’s not my own problem at all. Many of you are trying hard to put that perfect smile on your face. And as technology has done some crazy things like sending virtual lemonade through the internet, it can also navigate your winning smile.
Researchers at the University of Minnesota recently explored a new study, designed to discover the ingredients implicit in a perfect smile.
3D animation to find the perfect smile
To find the perfect smile, they teamed up with a digital artist and medical facial specialist to develop 3D, computer-animated virtual face smiling in a range of various ways to 802 people of different ages (ranging from 18 to 82). All of them had swigged less than six alcoholic drinks. Each of them was asked to rate from 15 random smiles they were shown for 250 milliseconds each. They had to rate those smiles on four categories- genuineness, effectiveness, pleasantness and perceived emotional intent. Total 27 faces were shown with a diverse level of smiles, angles of mouth and the number of teeth shown.
More is not always better
The study found that people with large smiles should reveal more teeth while smiling. For example, Julia Roberts, the queen of the rom-com has a dazzling smile that successfully works for her as she has a larger smile and the greater angle between her bottom lip and the top of her smile at the far corner.
However, that toothy smile may not work for everyone. The study suggests a tight-lipped smile may make you look more genuine and friendly if you have a smaller and less effusive grin.
So, what makes the perfect smile? The researchers found that symmetrical smiles that have an optimal time of 125 milliseconds for the sides to line up were rated well. A perfect smile has an optimal balance of teeth, mouth angle and smiles extent to hit the window of parameters or “smile sweet spot” that contradicts the “more is always better” principle.
You may wonder why they spent so much money and time to figure out the perfect smile. Well, this isn’t an open-ended experiment and does have some useful applications. The researcher can help physicians conduct successful facial reanimation surgeries on patients with partial facial paralysis. Also, the result could help create more realistic facial expressions and animations in digital environments. And what good it does to you? Well, you may have already found your perfect smile for that fire selfie.
