text: School would be nice to have a Facial Action Coding System because it would help with cheaters and thieves. Schools have many cheaters during tests. They're sneaky and really annoying. It'll just make things easier in school because students wouldnt want to cheat anymore because they'll know that they might get caught. Other reasons why is if a student is lying to the teacher about understanding the lesson or the chapter because they're embarressed of it. The teacher could just use this piece of technology to see whether the student is actually understanding the lesson or chapter.
