text: In some cases the Facial Action Coding System could be valuable to the classroom and learning environment. If a student is taking online courses or a school is predominantly taught by computer lessons, the Facial Action Coding System would help students stay more focused. The system could try to change the way of teaching based on the viewer's expressions. The system can also be beneficial to ads on computers. "...if you smile when a Web ad appears on your screen, a similar ad might follow. But if you frown, the next ad will be different" (D'Alto). This shows that the Facial Action Coding System could also make ads more interesting for those on computers often.
