text: "Oh it's nothing." replies Charlie who's obviously not as happy as he always is. Thomas would sure like to know how is friend is feeling; but he can't because there's no humanly way possible to if Charlie doesn't want him to know right? Well actually he can. There's a new kind of technology called Facial Action Coding System, or FACS, which enables computers to identify human emotions. The use of this technology to read the emotional expressions of students in a classroom is very valuable. Like in "Making Mona Lisa Smile" by Nick D'Alto, it could be used to show when a kid is becoming bored and let the teacher know so that the instructor could switch the lesson up to grab the kid's attention. Another effective was it could be used would be for it to show how some kids are feeling to limit them getting into any kinds of trouble. And finally it could be used to detect if one student just isn't grasping the matter of the subject that everyone else is getting with no problem. There are endless ways this technology could be used to better a classroom and this technology should be used in a classroom with students.
