text: Another person could say it is vaulable to help students and keep them entertained in a lesson and switch it up a bit. Dr. Huang is talking about how it can change the ads you see and veiw if you dont look happy when you look at them. Dr. Huang states "For example when a web ad appears on your screen and you smile a similar ad may follow, But if you frown the next ad will be different. A classroom computer could recognize when a student is becoming confused or bored," Dr. Huang predicts. This Quote and prediction of Dr. Huang states that is has potential to keep students intrestred into work but the problem being is that a program so complex like that requires so much code and algorithms that it requires a beffy computer to run so you would need to make multiple servers capable of holding that much information not only that but the school would have to divert much more of their budget toward stronger computers because Dr. Huang states Your home Pc cant handle the complex algorithms used to decode smiles" This saying from Dr. Huang proves that a PC for home use is not strong enough for this program so what makes you average home pc different from a school one other than filters put on the pc which reduces preformance but the worse thing that could happen is what if the power happens to shut down or go out do to a surge that program requires power to run so that is also a big problem.
