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 within a predefined selection zone to select the radial menu item.

Claims

1. A 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 comprising a center and a plurality of radial menu items placed radially outward from the center as pie slices, wherein one or more of the pie slices of the radial menu are each overloaded with two or more radial menu items, and wherein the overloaded radial menu items are each displayed at a different radial distance from the center of the radial menu;

receiving a first gesture of the screen pointer, wherein the first gesture activates at least a first menu item and a second menu item, the first menu item and the second menu item both displayed in one of the overloaded pie slices as overloaded radial menu items, wherein the radial menu provides a visual indication identifying the first and second menu items as activated menu items;

while the first menu item and the second menu item are activated, receiving either a predefined second gesture or a predefined third gesture of the screen pointer from a set of available gestures, the predefined second gesture and the predefined third gesture including screen pointer movements, wherein the predefined second gesture comprises moving the screen pointer in a stroke in a clockwise direction for executing a function associated with the activated first menu item, and wherein the predefined third gesture comprises moving the screen pointer in a stroke in a counter-clockwise direction for executing a function associated with the activated second menu item;

in response to receiving the predefined second gesture while the first menu item and the second menu item are activated, executing the function associated with the activated first menu item; and

in response to receiving the predefined third gesture while the first menu item and the second menu item are activated, executing the function associated with the activated second menu item.

2. The method of claim 1, further comprising:

displaying the radial menu for a predefined period of time after receiving the predefined second gesture;

receiving a predefined fourth gesture during the predefined period of time;

in response to receiving the predefined fourth gesture, reversing execution of the executed function.

3. 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.

4. 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.

5. The method of claim 1, wherein the first gesture places the screen pointer over the first menu item in the radial menu.

6. The method of claim 1, wherein the first gesture comprises moving the screen pointer in at least a direction different from the clockwise or counter-clockwise direction.

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

8. A non-transitory 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 comprising a center and a plurality of radial menu items placed radially outward from the center as pie slices, wherein one or more of the pie slices of the radial menu are each overloaded with two or more radial menu items, and wherein the overloaded radial menu items are each displayed at a different radial distance from the center of the radial menu;

receiving a first gesture of the screen pointer, wherein the first gesture activates at least a first menu item and a second menu item, the first menu item and the second menu item both displayed in one of the overloaded pie slices as overloaded radial menu items, wherein the radial menu provides a visual indication identifying the first and second menu items as activated menu items;

while the first menu item and the second menu item are activated, receiving either a predefined second gesture or a predefined third gesture of the screen pointer from a set of available gestures, the predefined second gesture and the predefined third gesture including screen pointer movements, wherein the predefined second gesture comprises moving the screen pointer in a stroke in a clockwise direction for executing a function associated with the activated first menu item, and wherein the predefined third gesture comprises moving the screen pointer in a stroke in a counter-clockwise direction for executing a function associated with the activated second menu item;

in response to receiving the predefined second gesture while the first menu item and the second menu item are activated, executing the function associated with the activated first menu item; and

in response to receiving the predefined third gesture while the first menu item and the second menu item are activated, executing the function associated with the activated second menu item.

9. 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.

10. 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.

11. The computer readable storage medium of claim 8, wherein the first gesture places the screen pointer over the first menu item in the radial menu.

12. The computer readable storage medium of claim 8, wherein the first gesture comprises moving the screen pointer in at least a direction different from the clockwise or counter-clockwise direction.

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

14. 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 comprising a center and a plurality of radial menu items placed radially outward from the center as pie slices, wherein one or more of the pie slices of the radial menu are each overloaded with two or more radial menu items, and wherein the overloaded radial menu items are each displayed at a different radial distance from the center of the radial menu,

receive a first gesture of the screen pointer, wherein the first gesture activates at least a first menu item and a second menu item, the first menu item and the second menu item both displayed in one of the overloaded pie slices as overloaded radial menu items, wherein the radial menu provides a visual indication identifying the first and second menu items as activated menu items,
