In this paper, we propose the touch panel's operation by using human fingernail and finger. And we developed the control circuit that measured X, Y coordinates and the electrostatic capacity in the resistive type of touch panel for this realization. In this research, the size of the touch panel is 213 x 160 mm, and the LED indicator is set up on the reverse side. In this device, the measurement of the coordinates and the electrostatic capacity was possible. Moreover, the input of human fingernail and finger was able to be judged according to the electrostatic capacity. The operation test presenting human the instruction by LED's lighting was executed. In this test, the input of fingernail was a tendency to distribute downward from the input of finger, and the deviation of these inputs was almost equal. Moreover, the inside success area of 90% was about 12 mm according to the relative frequency. The operation of these inputs has suited the Fitts' law because the contribution rate is above 0.8 in the operation time and the index of difficulty.
