Weekly Review:

Changed formula for acceleration. Now I have instead three different acceleration one linear acceleration.

lin_accel = Math.sqrt(accel_x^2+accel_y^2+accel_z^2) - earth gravity

Now by this data I can move only forward or backward. I want to use data from gyroscope and detect angle of rotation. Despite I added low pass filter, accelerometer data is quite unpredictable and my object instead of moving to one side, jumps from side to side. So, I stopped here trying to find solution. I need complex mathematical formula. Found similar project in research centre in Spain(here is their website http://roodin.crs4.it/). Look to this video http://www.youtube.com/watch?v=HTZFRDBdQck&feature=related. I asked them to guide me. Hopefully after finishing this part I will work on combination maps and my code.
