Performance on the character input. (a) Online accuracy of inputted characters (accuracy for the two-step procedure) in the DMD patients was 71.6% and that in the control was 80.6%, with no significant difference between them (t-test, p = 0.32). Each triangle (DMD) and circle (controls) indicates a data point. (b) Offline accuracy for both groups in each flashing sequence was plotted (triangle: DMD, and circle: controls).
