text: The new computer software stores similar anatomical information as electronic code. Imagine a computer that knows when you're happy or sad says the author. Examples that they use when a computer can tell if you are happy or sad is if you smile when a web ad apperas on your screen, a similar ad might follow. But, if you frown, the next ad will be different. That would be great because if you are watching something and then all of a sudden an ad comes on and you can't skip it, you want it to be entertaining and fun and not boring and dumb. It would also be very helpful if you are at school. "A classom computer could recognize when a student is becoming confused or bored", Dr. Huang predicts. "Then it could modify the lessson, like an effective human instructor" that would be really helpful for some people. Just, in case somone dosen't want to speak up if they are confused the commputer will know right away.
