text: First,computer to identify human emotions is really good thing because we would know If they are lying to us or no. Acoording the text " can we actually "calculate"emotions like math homework",I think they got the right point because our emotional is like calculate. They have to calculate are we really sad or happy. Another example from the text" The Mona lisa demonstration is really intended to bring a smile to your face, while it shows just how much this computer can do". I Hope our school should do like that so people we could help other people whenever we are sad.
