text: What if there was a machine capable of not only reconizing, but also understanding feelings via facial expressions? There actually is a machine that could do that. It is called the Facial Action Coding System, or FACS. This technology could be very useful in classrooms, it could reconize the emotions of the students, it could help identify or even prevent certain situations before they even happen by identifying a problem, and it could help give teachers much needed feedback on the class that they wouldn't verbally recieve.
