Sudden Motion Sensor


Please note that I wrote the motion sensor software several years ago. Since then, the motion sensor hardware in Apple computers has undergone several changes. Therefore, the software may not work correctly on some computers. Section 10.7.5 of the Mac OS X Internals book describes how to retrieve accelerometer data from the motion sensor. Also see the book's accompanying source code.
