Smile scans performed by automated machines are given daily to workers at Keihin Electric Express Railway in Japan. The software is provided by Omron Corporation. OKAO originally developed their smile recognition software for use in cameras or other consumer devices to help the camera focus on smiling faces, which tends to be what people want their cameras to do.
Keihin Railway workers, on the other hand, are forced to submit to the “smile police machine” every morning when they come to work. The Omron software checks a variety of facial characteristics, and then ranks the smile from 0 to 100; the consumer version describes this ranking as “percent smiling”.
Employees whose smiles fail to measure up are given computerized messages to encourage them to smile better. “You look too serious” and “Lift up your mouth corners” are typical feedback.
The workers also receive a printout of their daily smile, along with its smile ranking; this paper is kept throughout the day for purposes of inspiration.
