I'm currently trying to implement an augmented reality iphone application (ios 4.2) that uses accelerometer data to translate and rotate an OpenGl object on the screen. I have already managed to get the object to respond to the rotation of the phones, but this has always been an easy part.
For the translation part, I tried to apply some of the methods from this article (http://www.freescale.com/files/sensors/doc/app_note/AN3397.pdf) but it is still not very accurate. I am trying to apply a Kalman filter to filter accelerometer data.
Has anyone had any luck in determining phone traffic? If so, how accurately did you get it, and what methods did you use to get this accuracy?
