Abstract

Embodiments of the invention are generally related to graphical user interfaces (GUIs), and more specifically to selecting items from a radial menu. More specifically, embodiments of the invention provide a complex set of gestures which, when performed using a screen pointer, facilitate fast and accurate selection of radial menu items from a radial menu. The gestures may generally involve a first movement of the screen pointer to activate a desired radial menu item, and a second predefined movement of the screen pointer to select the radial menu item.

Claims

1. A computer implemented method for selecting a menu item from a radial menu, comprising:

receiving a predefined screen pointer event;

in response to receiving the predefined screen pointer event, displaying the radial menu on a display screen, the radial menu being bounded by a visible boundary;

receiving a first gesture of the screen pointer;

determining whether the first gesture places the screen pointer within a predefined selection zone of the menu item, the predefined selection zone extending outside the visible boundary of the radial menu;

upon determining that the screenpointer is within the predefined selection zone of the menu item, activating the menu item;

receiving a predefined second gesture of the screen pointer; and

in response to receiving the predefined second gesture, executing a function associated with the activated menu item.

2. The method of claim 1, wherein the predefined selection zone of the menu item is defined at least in part by a perimeter around the radial menu, the perimeter encompassing the radial menu.

3. The method of claim 2, wherein the perimeter is circular, and wherein the circular perimeter has a first radius from a center of the radial menu, the first radius being greater than a radius of the radial menu.

4. The method of claim 1, wherein the first gesture comprises moving the screen pointer in and out of the selection zones of one or more radial menu items.

5. The method of claim 1, wherein the display screen is a monitor and the screen pointer is a mouse pointer operated by one of a mouse and a trackball.

6. The method of claim 1, wherein the display screen is a touch screen and the screen pointer comprises one of a stylus pen and a human finger.

7. The method of claim 1, further comprising, closing the radial menu in response to receiving the predefined second gesture.

8. A computer readable storage medium comprising a program product which, when executed by a processor is configured to perform an operation for selecting a menu item from a radial menu, the operation comprising:

receiving a predefined screen pointer event;

in response to receiving the predefined screen pointer event, displaying the radial menu on a display screen, the radial menu being bounded by a visible boundary;

receiving a first gesture of the screen pointer;

determining whether the first gesture places the screen pointer within a predefined selection zone of the menu item, the predefined selection zone extending outside the visible boundary of the radial menu;

upon determining that the screenpointer is within the predefined selection zone of the menu item, activating the menu item;

receiving a predefined second gesture of the screen pointer; and

in response to receiving the predefined second gesture, executing a function associated with the activated menu item.

9. The computer readable storage medium of claim 8, wherein the predefined selection zone of the menu item is defined at least in part by a perimeter around the radial menu, the perimeter encompassing the radial menu.

10. The computer readable storage medium of claim 9, wherein the perimeter is circular, and wherein the circular perimeter has a first radius from a center of the radial menu, the first radius being greater than a radius of the radial menu.

11. The computer readable storage medium of claim 8, wherein the first gesture comprises moving the screen pointer in and out of the selection zones of one or more radial menu items.

12. The computer readable storage medium of claim 8, wherein the display screen is a monitor and the screen pointer is a mouse pointer operated by one of a mouse and a trackball.

13. The computer readable storage medium of claim 8, wherein the display screen is a touch screen and the screen pointer comprises one of a stylus pen and a human finger.

14. The computer readable storage medium of claim 8, further comprising, closing the radial menu in response to receiving the predefined second gesture.

15. A system, comprising:

a memory comprising a program; and

a processor which, when executing the program, is configured to;

receive a predefined screen pointer event;

in response to receiving the predefined screen pointer event, display a radial menu on a display screen the radial menu being bounded by a visible boundary;

receive a first gesture of the screen pointer;

determine whether the first gesture places the screen pointer within a predefined selection zone of a menu item, the predefined selection zone extending outside the visible boundary of the radial menu;

upon determining that the screenpointer is within the predefined selection zone of the menu item, activate the menu item;

receive a predefined second gesture of the screen pointer; and

in response to receiving the predefined second gesture, execute function associated with the menu item upon determining that the menu item is active.

16. The system of claim 15, wherein the predefined selection zone of the menu item is defined at least in part by a perimeter around the radial menu, the perimeter encompassing the radial menu.

17. The system of claim 16, wherein the perimeter is circular, and wherein the circular perimeter has a first radius from a center of the radial menu, the first radius being greater than a radius of the radial menu.

18. The system of claim 15, wherein the first gesture comprises moving the screen pointer in and out of the selection zones of one or more radial menu items.

19. The system of claim 15, wherein the display screen is a monitor and the screen pointer is a mouse pointer operated by one of a mouse and a trackball.

20. The system of claim 15, wherein the display screen is a touch screen and the screen pointer comprises one of a stylus pen and a human finger.
