The MoveIt! SDIO card from MotionSense was demoed. It combines memory with and accelerometer to allow you to tilt a palm forward/backward and right/left to navigate maps or control games.
Unfortunately, that company’s website is no more.
If I recall correctly, when Ryan saw this, one of the demonstrations he witnessed was using a Pac-Man-like game.
Here we are six years later and it’s now the Year of the Accelerometer. Without Palm.
