text: When there is a student that is getting bord or upset when a teacher is giving a lesson. The teacher cant just stop what they are doing to see what the student is upset or bord about. If schools allow students to have this kind of technology this may allow students to get a better undersatanding in the lesson. If a student is not understanding the lesson they will most likely lower there eye brows and in towards each other. This shows they dont understand what is going on. This will allow the computer to see why the student is not understanding or bord about. Than the computer will see this and modify the lesson so that the student will understand what is going on.
