Original caption: "Electronic Device Simulates Handwriting

Figure 'a' shows the word 'brew' as written by a test subject (bottom word) and by an electronic handwriting simulator (top word). The word 'brew' is used because it contains a variety of strokes with minimum number of letters. Figures 'b' and 'c' are produced by test subject, to simulate the subject's handwriting. Figure 'b' top line is vertical displacement, second line is vertical velocity, third line is vertical acceleration, and fourth line is horizontal acceleration taken from Figure 'c' for comparison. Figure 'c' shows, from top to bottom, horizontal displacement, velocity, acceleration and vertical acceleration, the latter from Figure 'b' for comparison. Note square form of acceleration waves, indicating discontinuous control."
