1. A method of processing a current gesture input, the method comprising:
- determining whether a direction of a long axis of an ellipse corresponding to the current gesture input is horizontal or vertical;
determining whether an elliptical arc position of an elliptical arc corresponding to the current gesture input is in a first position or a second position that is separated from the long axis;
determining whether a rotation direction corresponding to the current gesture input is clockwise or counterclockwise;
performing an action corresponding to the current gesture input in response to the determining that the direction of the long axis is vertical and the elliptical arc is in the first position; and
suspending the action in response to the determining that the direction of the long axis is vertical and the elliptical arc is in the second position,wherein the action comprises a first action and a second action different from the first action, the first action being performed in response to the determining that the rotation direction is clockwise, and the second action being performed in response to the determining that the rotation direction is counterclockwise.

19. An apparatus for processing a current gesture input, the apparatus comprising:
-
a sensor configured to detect the current gesture input; a processor configured to; determine whether a direction of a long axis of an ellipse corresponding to the current gesture input is horizontal or vertical; determine whether an elliptical arc position of an elliptical arc corresponding to the current gesture input is in a first position or a second position that is separated from the long axis; and determine whether a rotation direction corresponding to the current gesture input is clockwise or counterclockwise; and a decider configured to decide to; perform an action corresponding to the current gesture input in response to the direction of the long axis being determined to be vertical and the elliptical arc being determined to be in the first position; and suspend the action in response to the direction of the long axis being determined to be vertical and the elliptical arc being determined to be in the second position, wherein the action comprises a first action and a second action different from the first action, the first action being performed in response to the rotation direction being determined to be clockwise, and the second action being performed in response to the rotation direction being determined to be counterclockwise. - View Dependent Claims (20, 21)

22. An apparatus for processing a current gesture input, the apparatus comprising:
-
a sensor configured to detect the current gesture input; a processor configured to; determine whether a direction of a long axis of an ellipse corresponding to the current gesture input is horizontal or vertical; determine whether an elliptical arc position of an elliptical arc corresponding to the current gesture input is above, below, left of, or right of the long axis; and determine whether a rotation direction corresponding to the current gesture input is clockwise or counterclockwise; and a decider configured to decide to; perform a first action in response to the direction of the long axis being determined to be vertical, the elliptical arc position of the elliptical arc being determined to be left of the long axis, and the rotation direction being determined to be clockwise; suspend the first action in response to the direction of the long axis being determined to be vertical, the elliptical arc position of the elliptical arc being determined to be right of the long axis, and the rotation direction being determined to be clockwise; perform a second action in response to the direction of the long axis being determined to be vertical, the elliptical arc position of the elliptical arc being determined to be left of the long axis, and the rotation direction being determined to be counterclockwise; and suspend the second action in response to the direction of the long axis being determined to be vertical, the elliptical arc position of the elliptical arc being determined to be right of the long axis, and the rotation direction being determined to be counterclockwise. - View Dependent Claims (23)
