I haven’t come across too many hacks involving the Wii Fit Balance Board yet, but they are starting to emerge. In this recent demo, the board has been configured to control 3D movement in a game of World of Warcraft 3.
A couple of guys from DFKI (the German Research Center for Artificial Intelligence) took a Balance Board and connected it to a regular old laptop PC. A custom C# application communicates with the controller via Bluetooth, translating simple leaning movements on the board into 3D moves on the computer. By leaning forwards, back, left and right on the Balance Board, the player can move through a typical first-person view game with ease.
While this demo shows off some basic movements within Google Earth and WOW3, I’d venture to say that it could be easily modified to control any first-person 3D game. Imagine playing a FPS in which you hold onto a gun controller with your hands, and move around the environment by leaning. Even better yet, how about an FPS which supported ducking and dodging bullets on the Balance Board? Now that would be really cool. Only time will tell what other applications end up taking advantage of the board’s unique sensory abilities, but I’d lay odds that Wii Fit is only the tip of the iceberg.
