text: Finally, we can predict how a person feels even if they just are looking into a computer. "If you smile when a Web ad appears on your screen, a similar ad might follow. But if you frown, the next ad will be different. Our own computers can pick out ads for us to enjoy based on our intrests and facial expressioin. Nobody likes ads but this can make ads more tolerable then to get and ad about something that you have no intrest in. Computers will understand non verbale communication because these days people text and talk on the phone there is really not much talking in person so the computer will know that you are happy or sad when on a certain page or watching a certain ad.
