text: The machine called the Facial Action Coding System is valuable to students in a classroom because if a student is having all these different emotions going through their body and they dont know what to do about it, the machine could really help them with the problem. For example if a student is having the emotions of being happy, sad, angry, or even disgusted about something the machine could really help let someone know that the student is having these emotions going through their body. In the article "Making Mona Lisa Smile" it states "Using video imagery, the new emotion-recognition software tracks these facial movements-- in a real face or in the painted face of Mona Lisa. This states the machine would know the emotions of humans and even paintings of someones face.
