text: Some students might want to talk about it, but most probably wouldn't so it might make them even more upset or angry and sad if you ask whats wrong and they dont want to talk about it. Also if it a personal issue the student is having and they tell you what's wrong and you can't help them they might feel like they're doing something wrong and get sad or depressed becasue you can't help them. Also if this was used to read the emotinal expressions of students in the classroom I feel like it would be a distraction and take time out of the students learing to figure out how every student is feeling based on the facial expressions. Another thing could be what of the technology making this possible is wrong, so you walk up to a student and ask them why they're so happy but they are actually really sad. What if the student just changes their apperance to make them look a different way when they are read for their emotion. The last thing is what are the teachers going to do with the imfomation on how they think their students are feeling based on a facial expression. Maybe in a college where you want to be a consuler or something along those lines it would be a good thing to have to teach you how to read others emotions better, but it would be useless in a middle or high school classroom and just cause distractions.
