text: This system is not valuable in the classrom because it is an invasion of privacy. In the article it states that, "A classroom computer could recognize when a student is becoming confused or bored". That sounds good, but what the article is saying is that a computer is always analyzing the students face, and it does not say where the data goes. Also the computer could not be very well protected and a hacker looking to steal data could hack into the computer camera and steal the students idenitiy. Finally, what if the student doesn't like the system? Is he forced to use it or does he get a choice, the article does not state on whether or not there is any consent to this.
