Performance measures. (a) Launch error (LE) is the area (colored light gray) above the negative parts of the cursor-velocity curve before the target jump. Adjustment error (AE) is the area (dark gray) above the negative parts of the curve after the jump. (b) Launch latency (LL) is the time from target appearance till cursor velocity exceeds the mean plus 3 times the standard deviations of initial velocity. Adjustment latency (AL) is the time from the jump till peak velocity.
