text: In the passage it says, "hold on, we can actually calculate emotions." well yes if you actually give it a try. It would be seriously so cool to know how someone feels just by looking at a screen when they walk into a classroom. I think it would help some students, honestly if you tried this expirement. Students wouldn't know what to think if they had this in their classroom. None can just walk into a classroom and tell if they are happy or sad. It says that "the process begins when the computer constructs a 3-D computer of the face, all 44 major muscles in the model must move like humans."
