This technology can be valuable for students in a classroom. It can benefit both the teachers and the students. It can let a teacher know if a student is confused or bored and the teacher can try to teach the lesson in a different way so the student understands it better. As stated on paragrapg six, "A classroom computer could recognize when a studennt is becoming confused or bored, then it could modify the lesson, like an effective human instructor." If a student is having trouble but doesn't want to show it this technology can let the teacher know and possibly help the student. This technology can be very valuable in a classroom.

This technology can also benefit students who are typically shy, quiet, suffer from anxiety, or those who just don't like asking for help. It will also help detect whether a student genuinely understands a lesson or not. With this technology being able to detect emotions, it can let others know when someone is really angry and shouldn't be bothered.

Companies can benefit from this as well, as stated in paragraph six, "For example if you smile when a Web ad appears on your screen, a similar might follow. But if you frown, the next ad will be different." This will let companies know if they're doing good in their advertising. They can track the number of people who genuinely liked their ad.

This technology can be valuable not only in a classroom setting but in business and life. It can detect people's emotions and can let others know how the person feels. Companies can get updates on how many people liked or disliked their new ad. People who can't read others emetions well, will now be able to do so. Overall it can benefit a lot of people and it can be very valuable to have this technology in a classroom.
