Ball Invasion for iPad2: Find & Shoot Virtual Balls in the Real World

Here’s an interesting Augmented Reality (AR) app that is only for the iPad 2.

Ball Invasion for the iPad2

The app makes use of Simultaneous Localization and Mapping (SLAM) technology developed at NASA. It builds 3D maps of the world seen through the iPad 2’s camera and requires the proceesing power of the iPad 2’s dual core A5 processor. The SLAM technology provides tracking for the game’s AR that does not require the special markers needed by most AR apps.

The object of the game is to shoot the virtual balls “hiding” in the real world view. You can get an idea of how this works in the video embedded below.

The developers note that the app requires a lot of the iPad 2’s resources and that you may need to perform a soft reset in order to make sure the app has as much of the system’s resources as possible.

The app is currently available $1.99. This introductory price is half of its normal $3.99.
