The last thing that i am going to say that i am arguing that the use of technology to read the emotional expressions of students in a classroom, is this, like if a computer knows if you are happy or sad, it would do this, it would pull up an ad one might be sad and then the other one would be exciting and just make you happy in a way that you didnt know that you could be happy about something, for example, like a bunch of puppies,cats, someone just getting there drivers license and then getting a new car, something like that.
