text: They said that they have classified "six basix emotions- happiness, surpirse, anger, disgust, fear, and sadness. This might help a lot of people out if they do this. If you can tell a kid is sad you can help the kid. Maybe he or she is having problems at home and they need help but they don't say it. The facial action coding system might help people. It's a good idea, but it's actually a reall good expirement to test it out and see whats going to happen. You can alwyas take it out if it doesn't work out, or if it does you can keep doing what you are doing and you'll be able to see kids facial expressions and what they feel when they tell you they don't feel anything.
