The project Public Face I (Stimmungsgasometer) is about a smiley on a huge screen from which one can read the average mood of the Berlin citizens.
The system allows to read emotions out of random peoples faces. The faces are analyzed by sophisticated software (contributed by the Fraunhofer Institut). The obtained mood data are then stored on a server and processed by the smiley on the screen to visualize the emotions in real-time.
