Sony’s tennis racket sensor will help you improve your swing (hands-on)
CES isn’t just about 4K and connected cars; it’s a place where you can get a look at prototype technology from some of the biggest companies in the world. In Sony’s booth this year, it’s showing off what it calls the “Tennis Sensor”. The small nub affixes to the end of an ordinary tennis racket, and is able to detect the motion and vibration of the racket whenever you hit a ball. That information is then sent via Bluetooth to a tablet or smartphone, where Sony’s software can tell you the speed of your swing, the type of swing, and even where on the racket you connect with the ball.
