text: The FACS made by Prof. Thomas Huang could have many real world applications that would make life easier or more fun for some people. One of the many real world applications for this system would be Police Videos. You would be able to see the emotions on the criminal's face while he was being recorded on video, helping the police aid in the investigation. Another brought up by the article could be politics. You would be able to see how the politician is feeling, or which emotions. You would also be able to tell if they are faking emotions they are emitting while they are giving a speech, or if they are outright lying to you. The article itself says "To an expert, faces dont lie; these muscle clues are sometimes used to spot when a smiling politician or celebrity isnt being truthful." (D'Alto). The final point I want to bring up is how this could be used for therapy or working through yout problems.
