Feeling all right ... or not
Richard Wilhelmer's Public Face II, a.k.a. the Fühlometer ("feel-o-meter"), displays the public's mood in real time with a huge smiley face. Originally housed on top of a clock tower in the town of Lindau, Germany, it's now mounted on top of the Malzfabrik Gallery Space in Berlin.
This simple but engaging work uses software developed at the Fraunhofer Institute to analyze digital scans of faces on the street and ascertain whether the city's mood is upbeat, unhappy or indifferent. Depending on what the camera picks up, the giant face shows a smile, a frown or a straight-line mouth.
The cool part? Rather than having separate neon elements for the different faces, the mouth and eye pieces rotate among their possible positions.
