A PROGRAM FOR PARSING MOUSE-MOVEMENTS INTO COMPONENT SUBMOVEMENTS

Most current movement control theories include the idea that movement toward a target can be broken into several submovements. The complexit y of analyzing a movement into its constituent submovement structure a nd the additional complexity imposed by the problem of noise in the da ta and hand tremor seem to be daunting to researchers. This paper disc usses a program that can ameliorate both of these problems and parse m ovements into their constituent submovements. It also contains a graph ing feature that is useful as a visual tool for analyzing submovement structure. The programs are easily modifiable, so that researchers can specify their own parsing rules on the basis of different assumptions about movement control and use the parser for data from different exp erimental tasks.
