 Hey guys, it's Brian with The Verge. We're here at Sony's booth at CES. We're looking at what they're calling the Tennis Sensor. This is a prototype device. You put it into the end of a tennis racket. There are motion sensors in here, acceleration sensors. It can tell you basically the motion and how hard you're hitting a tennis ball with your racket including what areas of it you're hitting. Now I have not played tennis before. I don't play tennis regularly at all. In fact, I've never touched a tennis racket before so this is going to be interesting. Ah, it's awful.
