Computers can tell if you’re happy

A Japanese company has developed a smile measuring technology that could help computers and robots respond more effectively to human needs, Time reports.

Omron Corp, a Japanese electronics company, has developed software that evaluates the smile on a person’s face – as high as 89% for a person who was really grinning widely, while a sad face registered 0%.

The software can also pick out multiple smiles in a particular image – it can find and evaluate up to 100 smiles in a digital photo of a crowd of people.

The information used to make the evaluation is reportedly taken from a study of more than one million people and their smiles. The company intends to use the technology to help computers or robots to decipher human responses.
