1. An electronic device capable of operating according to an operation signal that is input, comprising:

  • a display unit capable of displaying a rotational pathway on a screen, with which an operation of the electronic device is associated according to a position on the rotational pathway;

    a touch screen that detects a touch from an outside and receives an input of a positional signal according to a position of the touch; and

    a main body controller including a touch detector that detects the position of the touch depending on the position signal input from the touch screen, a display controller that converts the position of the touch corresponding to the positional signal received by the touch screen into a position on the rotational pathway and causes a mark to be displayed at the position converted, and an operation controller that controls an operation of the electronic device according to a display position of the mark on the rotational pathway,wherein the display controller causes the mark to be displayed at an initial position on the rotational pathway that is a position originally touched on the touch screen, and determines a size of the rotational pathway on the display unit depending on a size of a display area of the display unit, andwhen the position of the touch is changed, the touch detector detects a change in an X direction and a change in a Y direction based on the positional signal input from the touch screen, the main body controller compares an absolute value of the change in the X direction with an absolute value of the change in the Y direction, and the display controller causes the mark to be displayed based on a comparison result between the absolute value of the change in the X direction and the absolute value of the change in the Y direction.
