Robert Oschler sent in this interesting project which allows Recording Emotions with the Emotiv EEG Headset to sense your mood. Just like the read receipt tells you if and when your email was read this would let you know what type of emotion it conjured.
“EmoRate is an application that demonstrates the power of Affective Computing, a technology that allows computers to detect and react to human emotions and will change drastically the way we interact with them in our daily lives. The last barrier that has held Affective Computing back, an affordable consumer grade EEG headset, has been broken with the introduction of the 14-electrode EPOC headset, created by Emotiv systems, Inc.”
