The PeekaBeat app is a new way to discover music that also might just improve your mood. It works using facial recognition technology. Users simply snap a selfie making a face that displays their current mood. The PeekaBeat app analyzes the photo and then suggests a 50-song playlist on Spotify. The idea is for people to use the PeekaBeat app throughout the day, either to boost their mood or drastically alter it in a positive fashion.
Most people are familiar with facial recognition through photo apps, but PeekaBeat is one of a handful of apps giving the tech a new function. It may not be long before people are unlocking their phones or finding restaurant recommendations using their faces.
