title: How to convert motion sensor data from Iphone to Android?
body: <p>I have some motion sensor samples that were recorded with an Iphone.
  Now I'm into calculating a distance between a user gesture and the gesture that was recorded on the Iphone. </p>
  
  <p>My problem is that the sensor data on the Iphone is represented in a different way then the android sensor data. If i don't move the Iphone I get data between -1 and 1 if I don't move my Android device I get values around 9 because the sensor measures the force of gravity.</p>
  
  <p>I couldn't figure out how to convert the Iphone sensor reading to compare them to my android sensor readings. The android motion sensor data is explained <a href="http://developer.android.com/reference/android/hardware/SensorEvent.html" rel="nofollow noreferrer">here</a>. And the Iphone documentation contains this <a href="https://developer.apple.com/iphone/library/documentation/UIKit/Reference/UIAcceleration_Class/UIAcceleration_Class.pdf" rel="nofollow noreferrer">pdf</a>. </p>
