This is an interesting idea, Smilophone – music is in your face!
Using emotional intelligence powered by Affectiva, Smilophone converts your expressions into music. Hold your iPhone or iPad up so it can see your face, and the music will play. Happy faces make happy sounds, sad faces make sad sounds. Raise or lower your eyebrows to raise or lower the tone. Have fun and make music as beautiful as you are!
