How do you get an accelerometer to measure distance travelled??
Well, it's an integrating process of all the accelerometer data and timestamps, i.e. how long the object is at the different g's.
Starting from last point at standstill, the g's at certain time will give a x speed or distance travelled depending on how you rearrange the formulae for speed and acceleration. integrating all the points up to the time of touchdown will give the final distance travelled.
mind though, you are dealing with 3d motion so, the math is vector math or/and matrixes.
Could be an interesting exercise though....
the games played with controllers with accelerometers do use similar techniques to translate accelerometer-data to movements in the game.
Since the data is postprocessed, then a visual graphics program could be used to visualize the data........
