The major difference is that ScriptAlyzeR™ does not offer interactive visual stimuli nor substroke segmentation.

Many movement tasts require visual stimuli. All example experiments show visual stimuli (some interactive), but some sample experiments can be done without them.

Above, targets change color and make sounds when reached.		ScriptAlyzeR™ only records handwriting movement without stimuli.

Strokes between targets in a Fitts' task (video EX3) consist of an initial, ballistic segment (i.e., primary submovement) and a subsequent adjustment to reach the target (i.e., secondary submovement). The tangential velocity is used to segment a movement into strokes and submovements. Frequency and the relative duration and size of submovements reveal significant effects while total stroke duration and size might show no significant effects.

The red circles are the stroke segmentation points. The black triangles are the submovement segmentation points. Coloring from light red to dark blue corresponds to the range from low to high absolute jerk (i.e., the change of acceleration).
