I found out about your app from my brother that has both an itouch and
an iphone. I’m writing an app that does the same thing for my Android phone. I have it getting the acceleration (in meters per second squared)
for all 3 axis (x,y,z) and it has a timestamp (releative since bootup)
in nanoseconds. I can choose to have these events either 10,20, or 50
times per second. A friend is helping but its been a month now, and I
still can’t convert from acceleration to distance traveled. I’ve checked
and rechecked my math and I’m doing something wrong (I’ve verified is not
a problem with the phone since I’ve tried it on other phones, and an excel graph of acceleration .vs. time looks fine). My math must be
wrong since even in the excel spreadsheet converting accel to velocity
and then to distance looks bad. Can you give a hand? PS its in java.
