A person named Amit Singh has figured out a way to use the Apple Motion Sensor (AMS), found in the latest generation of PowerBooks, as a human interface device. The AMS detects the movements of the PowerBook and can park the Hard Drive heads in the event of a sudden acceleration (such as during a fall). But now it has a new use; it can replace your mouse.

There are a number of concept videos showing a racing game and a game called NeverBall, both being controlled by tilting the PowerBook in different directions. It can also be used to scroll documents in various applications.

A free download of the software, AMS2HID, is available by clicking the first link below.
