title: Accelerometer & gyro accuracy in different mobile device
body: <p>I want to implement an indoor localisation system using the sensors of a mobile device (accelerometer, compass,
  gyro) . This problem was already discussed here on several places such as  - <a href="https://stackoverflow.com/questions/7829097/android-accelerometer-accuracy-inertial-navigation">here</a> and <a href="https://stackoverflow.com/questions/5314217/gyro-accelerometer-magnetometer-and-kalman-filter">here</a></p>
  
  <p>The first step is to decide which platform is the best one to implement such a system.
  The main possibilities are Samsung's Galaxy/ Galaxy tab, or the iphone/ ipad.
  The most important criteria is the accuracy of the sensors data. However, This comparison is very complicated, as the accuracy is dependent not only on the device itself but also on the software layers above it.</p>
  
  <p>Is there any research available on the subject? 
  Is there a difference between the sensors of smartphones and those of tablets?</p>
  
  <p>Any links to websites or articles would be <strong>most</strong> helpful</p>
  
  <p>Thanks in advance!</p>
