doing so could help to identify bumpy bike paths

Hi Thomas,

Your suggestion is quite interesting, I started some tests with a project from my office-mates based on this tutorial http://lopsi.weebly.com/uploads/2/5/6/4/25642375/pedestrian_dead-reckoning__pdr__tutorial.pdf

I'm looking forward to understanding the data from those tests, then if this is useful we can start thinking on that new feature for future experiments

Best,

Diego P
