Caption

Black, dark-gray, and light-gray arrows on the right correspond to the ending velocities of pen-tip writing the elements with “hooked,” “stop,” and “sweep” endings of hiragana letter shown in black, dark-gray, and light-gray on the left, respectively. The size and direction of arrows show the magnitude and direction of average velocity within a 50ms-window prior to lifting the pen. Overlaid arrows with the same color correspond to the multiple trials recorded at each week.
