text: But the down side of this is that it can only recognize certain emotions such as happiness, suprise, anger, disgust, fear, and sadness. But what if you have a diffrent emotion than that then what will the computer do when that happens just keep going how it is or will it try something new. By this passage i have learned that every thing in this would is changeing and that new technology is comeing out. But will this Facial Action Coding System really help children and teans lean new way that they understand i don't know but for now I agree that all computers should get this system becaue i know that if it really works that the pasage says that it does then i know that i would understand lessons in school way better than what i do now because it will adjust to how i like to learn and waht i find boring in the lessons that i am learning. So i that the use of this technology to read emotional expressions of student in the classroom would be ver valuabe. And could chang the world of learning forever.  Driverless cars would be useful and should continue to be developed because they would be potentially safer, more efficient, and help drivers by making driving a less intensive and dangerous activity.
