Inputs for Submovement Parameter Prediction.

*Position inputs underwent an additional processing step, taking the pairwise differences of the indicated position inputs. For 1D position inputs, differences were calculated as Euclidean distance. For 3D, the differences were calculated in three dimensions.
†Each 3D difference was normalized by the Distance To Target accounted for by All Prior Submovements (see text).
‡Remaining time was normalized to the duration of the submovement.
§The transformed t was e−20t.
1/4Velocity and acceleration were transformed by taking the 4th root.
