Detailed Description

script to derive the calibration parameters for the IMU

this script is used to derive the calibration parameters for the IMUs used in the experiments at ETH Zurich on 24.06.2010. the calibration parameters are derived by moving the IMUs in a dodecahedron before and after the participants made their trials. based on this movement, the calibration parameters can be estimated. the calibration parameters are then used to correct the acceleration data. the corrected data is then stored in a new file at the same location as the original file.

Function Documentation

selectStartEndMovement()

function selectStartEndMovement	(	in	acc,
		in	name )

select the start and end of a movement

this function allows the user to select the start and end of a movement in the acceleration data. the user is first asked to roughly select the start and end of the movement. then, the user is asked to select the start and end of the movement in more detail.

Parameters

acc	the acceleration data (Nx3)
name	the name of the movement

Return values

x_start	the start index of the movement
x_end	the end index of the movement
