Seeing someone smile at you is one of life’s great pleasures. And those who can see take that completely for granted. But Listerine and JWT London wanted to find a way to give those who can’t see warm fuzzies (and sell more mouthwash), so it created an app that plays a sound or vibrates when it detects a smile.
As it says on the site: “Smiles can change our mood, make someone’s day and even break down barriers, but sometimes we forget about the power of our smile. Whether you’re getting ready for a night out, or about to have the job interview of a lifetime, you should make your smile the best it can be.”
Listerine worked closely with the Royal National Institute of Blind People to ensure the app, which uses the front or rear facing camera and can be downloaded here, is accessible to blind and partially sighted people.
Smile detection technology certainly isn’t new, but the emotional response of the participants makes it a bit of a spine tingler. And it’s not the first time tech has been used to judge emotions. Beyond Verbal is an app that claims to know how you’re feeling based on your voice.
