text: How can this "Facial Action Coding System" even tell the Mona Lisa is 83 percent happy. The technology is not advance enough to say what emotions we have. How can this software even know the emotions we have on a picture. The Mona Lisa is a painting not a picture, so that cannot be corect. Da Vinci Code is something different from Dr. Huang's emotion algorithms. Communication doesn't have to do anything with the software, but maybe us the students.
