text: STUDENT_NAME   The use of this technology to read the emotional expressions of students in a classroom is not valuable. One reason is that for example if you read one of your friends emotions using this technology your feelings about them might change based on how they feel. People might not want others to know about their feelings or emotions so they show a different feeling or emotion and not be truthful then, you might not feel the same way you did in the beggining if you find out.
