I feel that this system would not be the right way to tell about someones emotions,jsut becuse you have a system that tells you this person is feeling his way doesnt mean they are actually feeling that way. Everyone has their own way of expressing either they way they feel or they way thefeel about something or someone. In the passage of paragraph 4 it says "his new computor software stories similar anatomical information as electronic code. Perhaps Dr. Huangs emotion algorithms are a different sort of ' Da Vinci code"! how can someone tell you how you actually feel about something jsut because it was made by a doctor that thinks he can make something up and tell you how your feeling. i wouldnt have a computor tell me how im feeling today or the next day. everyone has their own way of express how they feel. you shoudnt have someone telling you that oh your feeling this way today or your gonna feel this way the next day because everyone can feel different everyday. i woudnt use this system is it was me so i think this technology to read the emotional expressions of students in a classroom is not valuable. i wouldnt recommend anyone to use this system
