text: First, is how at the bare minium the Facial Action Coding System is worthless. From the "Making Mona Lisa Smile" article by Nick D'Alto, some perks it is able to include from this is only the idea of face reconition allowing ads to know whether you are smiling or frowning at the ad to know whether to keep ads like that or move on with new ones. This is a huge flaw because people can already log into a computer happy or upset but the FACS isn't going to know that so the system is basically ruined. Another thing is it being able to change a lesson to suit a students emotions if they are feeling confused or bored. This could be a good thing but how is it going to change the lesson to make it better? Even if it does it still wouldn't mean it would make it better for the student they could still be bored with the lesson making the FACS useless again.
