An input apparatus includes an input unit via which a user can point specific coordinates on a screen, and a display unit for displaying a graphical user interface (GUI). A menu for selecting an arbitrary item from a plurality of items is displayed on the GUI. When the user conducts manipulation to move a location of coordinates pointed by the user on the screen so as to draw a circle, center coordinates of a circle locus of the manipulation are presumed regardless of the location of the coordinates. An item selected in the menu is moved so as to be associated with a rotation angle of the manipulation with respect to the center coordinates. The user can conduct selection manipulation of consecutive menu items without depending upon the location of coordinates pointed by the user on the screen.
