Via point extraction by a tracing minimum jerk trajectory

It is known that reaching movements made by humans between two points can be reproduced by a minimum jerk model; however, some complex movements cannot be reproduced by simply linking two points. Here, we study the method for via-point extraction from a tracing minimum jerk trajectory under the assumption that in complex movement training, a subject first attempts to trace the path of an example trajectory and then finds via points from the tracing movement. From the results of computer simulation and measurement experiment, it was confirmed that the proposed method can effectively reproduce an example path.
