Computers Can Monitor Your Emotions Through Keystrokes

No one likes to think about feelings — those soft, emotional things we hide deep down inside in our unreachable corners. No one, that is, except for scientists and researchers at Facebook, who have managed to find the keys to our black, brutal hearts. We mean keys as in keystrokes. 

To provide data for the study, volunteers were asked to note their emotional state after typing passages of fixed text, as well as at regular intervals during their regular (‘free text’) computer use; this provided the researchers with data about keystroke attributes associated with seven emotional states (joy, fear, anger, sadness, disgust, shame and guilt).
