Submission + - Microsoft's 9-axis sensor fusion system for tablet (geek.com)
An anonymous reader writes: What the Windows engineering team have discovered is the typical 6-axis motion sensing offered through the inclusion of a 3D accelerometer and 3D magnetometer has some major flaws. More specifically, they are limited in how accurate and responsive feedback can be in the hands of a user.
With that being the case, Microsoft added a third sensor in the form of a 3D gyro for sensing rotational speed and then started experimenting. By combining the three sensors, what Microsoft refer to as a 9-axis sensor fusion system, it was possible to overcome the shortcomings of each sensor type to provide a much better system.
