According to the invention, a method for plotting a 3D movement in a 1D graph, is described which comprises the steps of:
a) measuring the orientation values of a 3D motion sensor device for a 3D movement,
b) sub-sampling the orientation values of step a) by using a reduced number of subsample onentation values,
c) assigning a 1D-numerical value to each of the sub-samples of step b),
d) calculating the projection of a sample of the 3D movement on a path defined by the sub-samples by calculating a projection of the sample between each consecutive pair of sub-samples,
e) taking a weighted average over the projections calculated in step d)
f) repeating steps d) and e) for each orientation value of step a), and
g) plotting the 1D numerical values of the samples of the 3D movement in a ID graph.
In this way, an improved and more intuitive method to plot a complex 3D movement in a 1D graph is provided. According to the invention, further a method for comparison of two arbitrary 3D movements and a device for carrying out the method are provided.
