Sony Ericsson have patented a system whereby a cellphone could be controlled by facial expressions, shuffling between music tracks according to visual mood analysis. The patent, titled “Generating music playlist based on facial expression”, describes capturing an image of a user and using facial recognition to build a custom playlist depending on the listener’s mood.
The system could either recognize moods by spotting particular facial characteristics or by comparing the whole face against presets; alternatively, a hybrid of the two might be applied.



While not pursuing criminals and thefts, Face Recognition apps has its niche use in advertising. NEC’s new digital signage system presented Eye Flavor, a masterful 46-inch LCD that can read viewers expression, analyze and display the most effective content then store all measurements for marketing use.
