Hi Tom could you please enlighten me by explaining the runge kutta integration that you used? i understand that it takes weighted average, giving more weight to the values in between, but i don't understand how it is working without considering the actual "slopes" and "step size", and differential equations are not considered.

referring to the equation on wikipedia, we can't just treat values as our "slopes" right?
also, do u have any papers i can refer to regarding usage or runge kutta on accelerometer data?

Hi Mr.Pizza,

Don't pay too much attention to that. It was just a quick familiar way to combine integration and some simple noise filtering. Any simple other way to do it would probably also be just fine!
