Here's the iPad app's version of the Keys to the Match screen (I showed you the Web version in my last post), showing three key performance indicators (KPIs) for each player, predictive of their likely victory. As shown here, Serena Williams triumphed in her match against Sara Errani on Friday night, and she also exceeded the required threshhold on all three of her KPIs.
Many of the stats and analytics available on the usopen.org Web site and the US Open iPad and smartphone apps are available -- and differently visualized -- on the giant touch screen IBM Game Changer Interactive Wall, where I started my tour. The Interactive Wall is available to all attendees of the US Open.
Just as the iPad App can show you customized Keys to the Match data for each player, so too can the Interactive Wall. Here we see that Andy Roddick was only winning 47% of "rallies" with 2 or fewer shots. To win the game, IBM's analytics said he should have been winning at least 56% of such points.
