iphone Programming Glossary: gyroDetecting Acceleration in a car (iPhone Accelerometer) http://stackoverflow.com/questions/2733249/detecting-acceleration-in-a-car-iphone-accelerometer answer that leads to a solution. iphone objective c physics accelerometer share improve this question You need a gyro. Otherwise there are multiple configurations of an accelerating car on a hill that can give rise to exactly the same readings.. an accelerometer. They will be completely impossible to distinguish. That's why inertial navigation systems combine a gyro and accelerometer. The reason you can't do this was given by Einstein Using a local measurement you can't distinguish between.. gravity in two different locations without a means to carry out what's called parallel transport . This is what a gyro does. Forget the 250 but I think you should give me a beer for the amount of R D time I'm saving you. share improve this..

I want to compensate for the slowness of the compass.. like some help with an issue I'm having. I want to compensate for the slowness of the compass by using data from the gyroscope. Using CMMotionManager and its CMDeviceMotion object motionManager.deviceMotion I get the CMAttitude object. Correct..
iphone - core motion range of yaw, pitch and roll http://stackoverflow.com/questions/5004548/iphone-core-motion-range-of-yaw-pitch-and-roll the interest of starting the ball rolling I'm assuming you are talking about the device attitude rather than the raw gyro data. Anecdotally I have an ipod touch 4 gen sitting in front of me displaying these values pitch looks to be a range of..
