What do you get here?

float speed = Math.abs(x+y+z – last_x – last_y – last_z) / diffTime * 10000;

What does the addition and subtraction of accelerations on different axises mean – I think x, y and z aren’t vectors, are they?

I am trying to detect the direction, so will extend your approach to measure the difference of the acceleration values. Cheers! Cass Thanks for the info.

Actually, if you remember your physics course, a real velocity is a vector, with components in all three dimensions. The velocity in only one direction would be more precisely called a "scalar velocity" in that direction, and more worthy of the "pseudo" tag. “(I call it psuedo because it’s not actually a velocity in any direction; it’s more like a mixed-up velocity from 3 axises).”
