A Japanese company called Keihin Electric Express Railway Co. has introduced a “Smile Scan” system. It aims to evaluate the smiles and grins of its staff.
The device analyzes the facial characteristics of a person including: eye movements, lip curves and wrinkles. It also rates the smile on a scale between 0 and 100 percent.
“We aim to improve our services to make our customers smile,” says a company official.
Now I just started laughing when I first read this. Such a bizarre idea. I wonder if it can detect fakes smiles
