Abstract: A digit-operated input device used for entering data into an electronic device includes: a dragging line, a digit locator, a press sensor, and a control unit. One end of the dragging line is connected to a user's digit while the other end is connected to the digit locator, which outputs a position signal when the position of the digit is detected through the dragging of the dragging line. The press sensor detects a pressing motion of the digit and then outputs a press signal. The control unit is connected to the digit locator and the press sensor to integrate the positional signal and the press signal and to output the same to the electronic device.
