I believe that this technology to read students' emotional expressions is a great idea.

"A classroom computer could recognize when a student is becoming confused and border." "Then it could modify the lesson, like an effective human instructor."

The same technology can make computer-animated faces more expressive --- for video games or video surgery.

It would be a good change, it could range our lives for the better. A computer that can tell our emotions could bring us so many opportunities.

I see why some people might not feel the need for it simply because, we have teachers, and they can tell our emotions or some people just might think there simply isn't a need for computers to know how me feel by our facial expressions, they may feel as if it's pointless.

But I do truly feel as if is a good idea to have them, they seem fun and really cool. Something that can benefit our lives in so many way, and it could possibly be used as a fun little toy on the side. But all together the idea is great.
