text: Teachers in public schools can have up to 40 students in one class and they can't help all of them at once. Teachers are human, they can't be in two places at once or helping two students at once. With the Facial Action Coding System, computers can modify their lesson and teaching to specific students and give them the help that they need to understand the standards. All students don't learn the same way and all teachers cannot possibly have time to help each and every one of their students individually. This technology can make studies a little bit easier for everyone, even the adults.
