That technology would not help in schools because the fact that students are sometimes not happy with how computer ads put up. Teacher can also see how their students are feeling on the computer but one flaw about this is that what if it didn't work. The technology would have to have many updates to get the system right and make the experiance better. Someone can hack that computer and can be watching you or the government might be trying to watch us. How much is schools going to be paying for these compter? Maybe around a million dollars in buying and fixing it. Most schools don't have good internet or they have bad students that might break these computers and the school or stduent would have to pay for it. The computers schools have now barely even work now so why buy a computer that most likely not going to work no better than the computers they already have. Why take away a ad and putting a new ad is going to make a student happy? What if they dont like ads at all? what is the point of the putting a computer that can read people emotions by scanning their face and the students are not going get any happier they are going be excited about at first and then get bored with it. Computers are not good for kids at a young age they will get addicted to being on a computer won't go outside and then they are going to gain weight and then be fat.
