Rate the following essay on its writing, argument, and language skills:
Prof. Thomas Huang and Nicu Sebe collaborated to innovate a computer software called the "Facial Action Decoding Sytem", which recognizes facial emotions. The software can construct a 3-D model of the face and is programmed to recognize specific traits. Basic emotions such as happiness, surprise, anger, fear, and sadness can all be detected, as well as a mix of them all. This innovation has the potential to be revolutionary if placed in a classroom.

Many emotions are portrayed by students every day, and they can be a key factor in student effort. For example, a tired and bored student is more likely to lose focus and be less attentive than a well-rested and pleased student. The Facial Action Decoding System has the abillity to detect boredom. Dr. Huang stated , "A classroom computer could recognize when a student is becoming confused or bored. Then it could modify the lesson like an effective human instructor." He sees the educational benefits to students if his software were used in a classroom. Students would be able to stay focused longer and continue to do so without boredom. A happy student would be much more willing to learn with a software that kept them focused and happy.

With the Facial Action Decoding System in a school, or at home on a PC, everyday computer activities will get more and more interesting. For example, digital advertisements are just about everywhere nowadays, and some of them can be annoying an even disturbing. However Huang's software can process the facial reaction of a user to determine which adds to allow them to see. "For example, if you smile when a Web ad appears on your screen, a similar as might follow. But if you frown, the next ad will be different," Huang predicted. Putting a software with the abillity to do this would benefit students and teachers. Ad's can pop up in school that may not be appropriate or have anything to do with a desired subject. If the reaction of the student teaching that subject is negative, the ad will not be seen again. On the other hand, a teacher could find an ad that would benefit a lecture or teaching segment, and more educational ads will appear.

Others claim that the idea of a software that constantly watches a student's face is bizzare. They claim that humans can already detect when something is wrong with a student, or if they arent participating well. While humans can observe a student's emotions, it is not as precise as Huang's software. Given that some may be feeling well but prefer a calm and relaxed demeanor, humans will not know what these students are feeling at the time. However, the software will use all of the facial muscles to determine how these students really feel emotionally.

Huang and Sebe's Facial Action Decoding System truly demonstrates how facial motions can show mental feeling. This is why it would be extremely beneficial to have in schools. Students and teachers would get to experience a fully customized day at school based on their emotions for that day. This will eliminate loss of focus and amplify participation, which is crucial for all student succes.
