Poker Face

Poker Face is a wearable device that tracks changes in the wearer’s mood and gives real-time feedback, so they can change how they’re interacting. It also uses photos and Google Calendar events to give a complete picture of your interactions with people, time, places and the environment.
It includes galvanic skin response (with fabric sensors), a heart rate sensor, an Arduino LilyPad (a brand new one, thanks to Tom Igoe), and a phone, which works as screen, camera and database. All the sensor values and pictures the device takes are used to create visuals of the days, weeks and months.
The phone helps you become aware of your unconscious feelings, and it also lets the people around you recognize them and react accordingly.
The visual interface lets you look at the sensor data next to your calendar and pictures and make your own guesses about how you felt. It works like an emotional memory, and helps you see patterns and make changes in your life.
