Ever feel like your teacher just didnt understand what you were going through? Well, researchers at the University of Massachusetts Amherst and Arizona State University are busy designing computerized tutors designed to teach and feel. The machines will be outfitted with sensors that pick up whether a student is angry, frustrated or bored. For instance, a computer vision system will study the subjects facial expressions—even something like the tilt of the persons head can be an indicator of his or her level of interest.
