gyro and accelerometer together (on Android it is SensorManager Class).So my questions are:Are those values (pitch, roll and yaw) relative to the magnetic north and gravity?If above is correct, how can I modify it to give me results relative to the But the “secret sauce” is in a state-of-the-art SBG developed calibration algorithm… SBG buys MEMS gyros and accelerometers from MEMS manufacturers compass reference system with much higher roll and pitch accuracy than the two SBG products Providing precise measurements for both pitch and roll angles over a full orientation range of The ADIS16210 integrates ADI’s iMEMS multi-axis accelerometer technology and signal processing expertise, adding addressable user registers for application It’s got the lot, starting with a six-axis “Inertial Measurement Unit” (IMU) that uses gyros and accelerometers to measure pitch, roll, yaw, and acceleration from front to back, left to right and up to down. This unit communicates with the Yamaha The MEMS gyro chip will be used in the upcoming Wii MotionPlayer are pitch and roll," claimed Joe Virginia, marketing director at InvenSense. A ring-shaped, two-axis gyro measures two perpendicular directions of angular momentum, unlike an Performance Designed Products (or PDP) plans to offer a motion controller for the Xbox 360 sometime this fall. This new controller called the Gametrak Freedom uses several accelerometers for mapping pitch, roll, and yaw. The controller differs from the Wii .

Take the Lamborghini Piattaforma Inerziale, or inertial platform, a little aerospace-derived box containing a set of accelerometers and gyroscopes tasked with measuring the Huracán’s yaw, pitch and roll in real time -- then feeding that information All the LandMark™ VG's use only gyros and accelerometers to accurately calculate pitch and roll angles with no other sensor inputs required. The unit also can accommodate a wide input power range from +6V to +36V. All our VG's share a common VG messaging Two researchers from the University of California Davis, Hao Chen and Lian Cai, have successfully divined the keystrokes on an Android on-screen keyboard by measuring the wiggles, jiggles, and vibrations picked up by the device’s accelerometer.
