text: Another reason why is could it could be valuable for a student in a classroom is to see if a student is depressed. If a student has a mental disease like depression or bipolar, the software can know if a student is feeling depressed or if a students emotions change by seeing how their muscles move. The teacher can help the student if he/she has depression when a student is trying to hide it. In the text it says," They even indicate the difference between a genuine smile and a forced one." This could help the software be more valuable.
