Abstract

A method, in a computer system including an interactive display surface, of controlling the display of a user interface menu, the method comprising: displaying a menu option in each of a plurality of active display positions, each display position being located at one of a respective plurality of active radial positions radiating from a central position; detecting movement of a contact point on the interactive display surface; and changing the menu option displayed in each of the plurality of display positions in response to the detected movement of the contact point being inward or outward of the central position.

Claims

1. A method, in a computer system including an interactive display surface, of controlling the display of a user interface menu, the method comprising:

a. displaying, by at least one processor, a menu information option in each of a plurality of predetermined static active display positions, each display position being located at one of a respective plurality of active radial positions radiating from a central position;

b. detecting, by at least one processor, movement of a contact point on the interactive display surface; and

c. changing, by at least one processor, the content of the menu information option displayed in each of the plurality of predetermined static active display positions, whilst the predetermined static active display positions are positionally maintained, in response to the detected movement of the contact point being inward or outward of the central position.

2. The method of claim 1 wherein the step of detecting movement of the contact point on the interactive surface includes a heuristic for determining that the movement of the contact point corresponds to a radial gesture based on an angle of the detected movement with respect to a radius extending from the central point.

3. The method of claim 2 wherein in the heuristic a detected movement within a predefined angle of a radius is determined to comprise a radial gesture.

4. The method of claim 2 further comprising determining the radial gesture as being inward or outward in dependence on whether, respectively, the radial gesture is toward or away from the central point.

5. The method of claim 1 further comprising the steps of:

a. displaying a menu option in each of a plurality of inner display positions, each inner display position being associated with an active display position, each inner display position being located at one of a respective plurality of inner radial positions radiating from the central position, the inner radial positions being located a shorter distance from the central point than the respective active radial positions;

b. changing the menu option displayed in each of the plurality of active display positions to the menu option in each of the plurality of associated inner display positions in response to the detected movement of the contact point being outward of the central position; and

c. changing the menu option displayed in each of the plurality of inner display positions to the menu option in each of the plurality of associated active display positions in response to the detected movement of the contact point being inward of the central position.

6. The method of claim 1 further comprising the steps of:

a. displaying a menu option in each of a plurality of outer display positions, each outer display position being located at one of a respective plurality of outer radial positions radiating from the central position, the outer radial positions being located a further distance from the central point than the respective active radial position;

b. changing the menu option displayed in each of the plurality of active display positions to the menu option in each of the plurality of associated outer display positions in response to the detected movement of the contact point being inward of the central position; and

c. changing the menu option displayed in each of the plurality of outer display positions to the menu option in each of the plurality of associated active display positions in response to the detected movement of the contact point being outward of the central position.

7. The method of claim 1 further comprising the step of rotating the menu option displayed in each of the plurality of active display positions in response to the detected movement of the contact point being rotational movement about the central position.

8. The method of claim 1 wherein the menu options in each of the active display positions represent a current set of menu options available for selection by a user.

9. The method of claim 1 in which the interactive display surface is a touch-sensitive display surface.

10. A non-transitory computer-readable medium storing a program causing a computer to execute the method according to claim 1.

11. A computer program product for storing computer program code which, when run on a computer, perform the method of claim 1.

12. A computer system associated with an interactive display surface, adapted for controlling the display of a user interface menu, the computer system comprising:

a. a menu display module adapted to display a menu information option in each of a plurality of predetermined static active display positions, each display position being located at one of a respective plurality of active radial positions radiating from a central position; and

b. a touch detection module adapted to detect movement of a contact point on the interactive display surface;

c. wherein the menu display module is further adapted to change the content of the menu information option displayed in each of the plurality of predetermined static active display positions, whilst the predetermined static active display positions are positionally maintained, in response to the detected movement of the contact point being inward or outward of the central position.

13. The computer system of claim 12 further comprising a radial gesture recognition module adapted to detect movement of the contact point on the interactive surface as corresponding to a radial gesture, based on an angle of the detected movement with respect to a radius extending from the central point.

14. The computer system of claim 12 wherein the menu display module is further adapted to:

a. display a menu option in each of a plurality of inner display positions, each inner display position being associated with an active display position, each inner display position being located at one of a respective plurality of inner radial positions radiating from the central position, the inner radial positions being located a shorter distance from the central point than the respective active radial positions;

b. change the menu option displayed in each of the plurality of active display positions to the menu option in each of the plurality of associated inner display positions in response to the detected movement of the contact point being outward of the central position; and

c. change the menu option displayed in each of the plurality of inner display positions to the menu option in each of the plurality of associated active display positions in response to the detected movement of the contact point being inward of the central position.

15. The computer system of claim 12 wherein the menu display is further adapted to:

a. display a menu option in each of a plurality of outer display positions, each outer display position being located at one of a respective plurality of outer radial positions radiating from the central position, the outer radial positions being located a further distance from the central point than the respective active radial position;

b. change the menu option displayed in each of the plurality of active display positions to the menu option in each of the plurality of associated outer display positions in response to the detected movement of the contact point being inward of the central position; and

c. change the menu option displayed in each of the plurality of outer display positions to the menu option in each of the plurality of associated active display positions in response to the detected movement of the contact point being outward of the central position.

16. The computer system of claim 12 further comprising a rotational gesture recognition module adapted to:

a. detect movement of the contact point being rotational movement about the central position,

b. the menu display module being further adapted to rotate the menu option displayed in each of the plurality of active display positions on the active circumference in response thereto.

17. The computer system of claim 12 in which the interactive display surface is a touch-sensitive display surface.

18. The computer system of claim 12, further comprising an interactive display system.
