Here's how Zack Whittaker from ZDNet explained it:
The Augusta National Golf Club, which hosts the Masters every year, has dozens of lasers scattered throughout the course. Those lasers kick out a number of different pieces of data, including the location of the ball (determined on three-axes) and the resting position of the ball, which IBM runs through its cloud and visualizes. The end result is a play-by-play visualization that allows the viewer to interact and see the ball's course, the distance of each drive, and other interesting nuggets of data. And this happens in a matter of seconds. Simply put, you can take any device and crank open the Masters' website, and see how the ball traveled throughout the course. Using the HTML5 web standard, any smartphone or tablet user can access a simulated map of the course. iPad users have the benefit of using the internal gyroscope to visualize the play from any angle.
Click on any shot and Track displays both the yardage and the yardage remaining, and it gives the length of every putt. It's easy to see why so many are utilizing this new tool in conjunction with watching the television broadcast. It's like having your own universal instant replay. No more wondering about what your favorite players are up to off-camera.
Interestingly enough, there's a platform currently on the market that provides these very same features to the average golfer... Enter GAME GOLF. Here's a look at a screenshot taken from within the Game Golf platform:
By inserting tiny ball marker sized sensors into the ends of each golf club, the Game Golf platform is able to wireless track any golfers entire round, providing a wealth of statistical and game improvement date for in depth analysis. Available for only $199, I can't think of a more useful tool for improving your game.
I personally have tested out the Game Golf platform, and very quickly became a believe and supporter. I now wouldn't even consider playing a round without Game Golf. Post round reviews have become a regular part of my routine, which strangely enough, I enjoy nearly as much as being out on the course.
