perfect smile

A Japanese company named Omron has created a device that scans a person’s face, renders a 3D model of it and checks a few critical spots (mouth, eyes etc.) to evaluate if someone is smiling hard enough. Every smile gets a percentage from 0% to 100%, with 100% obviously being the perfect smile (see the picture below). The device, which consists of a small analogue video camera, a sensor unit and a piece of software, is only available in Japan at this point.
