The zero points in the velocity are to remove velocity drift from the calculations using MEMS components. It's probably best to ignore those points as they're where I calculated stationary (or some percentage either side of stationary).
As I mentioned, it was visibly slower, and calculating the...
Thanks for your reply. Sorry I was a little vague. Think of the lifting activity as a benchpress of sorts, so the weight is only being lifted in one dimension. Unfortunately the device recording the session wasn't mounted in a perfect perpendicular way so the three dimensional planes aren't...
I'm trying to get an understanding on what's going on with some data of mine. I've attached some plots below.
This data is from and accelerometer and gyroscope where I've calculated the global accelerations and velocities (top and bottom plot respectively in each figure). The data is from the...
