Concluding Statement: Based on the evidence given in the article, the use of Facial Action Coding Stystems in the classroom would be wildly valuable. The computer can detect many levels of emotion to accomodate their program to the students' needs. If a particular lesson bores a student or that student has lack of focus, the computer can adjust and change many aspects of thier layout to catch the student's attention. Also, students can receive the correct level of work- whether that be too easy or too hard. And not only can students benefit, but teachers, as well. They can track student progress to further accomodate their needs. While technology can be used for many unethical things, the Facial Action Coding System would be extremely effective in a school setting.
