Experimental design. A, top, Hand-cursor velocity scaling for conditions where the cursor position leads the hand position in y-axis (matched-cursor late-peak hand velocity condition, blue, and matched-hand early-peak cursor velocity condition, yellow). Bottom, Hand-cursor velocity scaling for conditions where the cursor position lags the hand position in y-axis (matched-cursor early-peak hand velocity condition, green, and matched-hand late-peak cursor velocity condition, purple). B, Hand and cursor velocity-position profiles required to achieve the ideal movement to the target. Left, Matched-cursor velocity conditions. Middle, Baseline condition, where cursor position and hand position are consistent. Right, Matched-hand velocity conditions.
