1. A touch input method comprising:
- receiving a touch input signal corresponding to a finger from a touch-sensing device;
detecting a contact area between the touch-sensing device and the finger corresponding to the touch input signal received; and
recognizing the finger corresponding to the touch input signal received as a thumb if the contact area exceeds a curvature threshold value below which the contact area is recognizable as a circle.
