For example is the text it states "your frontalis pars lateralis muscle (above your eyes) raises your eyebrows when you're surprised; your orbicularis oris (around your mouth) tightens your lips to show anger." This is how that computer knows how you are feeling, by look at your muscles. If they did have the emotional expressions inside of the class room then you will be able to tell if the student is telling the truth or not.
