user3339: I am using MPU6050 IMU for getting accelerometer and gyro data. I could read the data using the code from the I2Cdev library here, but the problem I have is that I can't use this data in a meaningful manner. As an example I want to define the motion of an object in x,y,z axis using accelerometer data. Although I get a set of values, I can't understand how to use it.
If I could convert these values to ms-2 units, I hope I would be able to achieve this
Could you provide me some advice, code or reference to work on this?
I also tried the code here to get the raw values. 

user3219: You may want to take a look of freeimu library which take care of all needed processing and present filtered and data-fused data (not just raw data) in easy to use roll, pitch and yaw format.

see demo video in which the on screen data mirror physical motion of the sensor
