text: In my opinion i think this would cause good controversials because your emotions would simply be easy to reach like in Mona Lisa picture. Your expression can change real quick as to when your standing in the mirror or when you are really happy , sad, or mad. This would help for when a person is showing a fake smile or when a celebrity is being truthful with the camras. This would be a great idea in the future because it would help alot of photographers and scientist that want to look over a picture and tell your facial emotions such as anger, sadness, surprised , disgust, and fear. These would be part of improtant and many more facial emotions.What if teachers couldn't teach anymore and we had to rely on technology? The technology to read the emotional expressions of students in a classroom is valuable because, it can help educate the children. There's technology out there that can help people learn.
