Abstract

A free-flowing user interface for a touchscreen device of a mobile electronic device provides touch-sensitive application icons and a touch-sensitive hotspot having an optional activation radius surrounding the hotspot. A user can launch a selected application by touching the hotspot and then touching and dragging the application icon corresponding to the selected application onto the hotspot or at least partially into the activation radius surrounding the hotspot. Alternatively, an application can be launched by dragging the hotspot and its surrounding activation zone such that the hotspot or activation zone at least partially overlaps the application icon of the application to be launched. The free-flowing interface can be optionally enhanced by displacing icons onscreen, when dragged or when collisions occur between icons, based on at least one of a virtual inertia parameter, a virtual friction parameter and a virtual collision-elasticity parameter to create more realistic onscreen motion for the icons.

Claims

1. A mobile electronic device comprising:

a memory operatively connected to a processor for storing and executing an application; and

a touchscreen for displaying both a touch-sensitive application icon corresponding to the application and a touch-sensitive hotspot for launching the application.

2. The mobile electronic device as claimed in claim 1 wherein the touchscreen further comprises an activation zone surrounding the hotspot within which the application icon can be dragged to at least partially overlap the activation zone in order to launch the application.

3. The mobile electronic device as claimed in claim 1 wherein the hotspot is a movable hotspot that can be dragged at least partially onto the application icon and then released to launch the application corresponding to the application icon.

4. The mobile electronic device as claimed in claim 1 wherein the hotspot is a movable hotspot that can be dragged with a surrounding activation zone so that the activation zone at least partially overlaps the application icon for launching the application.

5. The mobile electronic device as claimed in claim 1 wherein the hotspot is a circular hotspot around which an annular activation zone is concentrically disposed to define an activation radius within which one or more application icons can be dragged for activation of respective applications.

6. The mobile electronic device as claimed in claim 1 wherein a plurality of application icons are arranged onscreen such that application icons corresponding to applications that are frequently launched are disposed closest to the hotspot to enable greatest accessibility to the hotspot while application icons corresponding to applications that are infrequently launched are disposed farthest from the hotspot.

7. The mobile electronic device as claimed in claim 1 wherein the application icon comprises a virtual inertia limiting onscreen acceleration and deceleration of the application icon when dragged.

8. The mobile electronic device as claimed in claim 1 wherein a plurality of application icons displayed onscreen each comprise a virtual inertia limiting onscreen acceleration and deceleration of the application icon when dragged and furthermore causing reactive displacement of other onscreen application icons when onscreen collisions occur.

9. The mobile electronic device as claimed in claim 8 wherein the application icons each comprise a virtual friction parameter and a virtual collision-elasticity parameter for limiting the motion of onscreen icons that are subjected to onscreen collisions.

10. A method of launching an application using a touchscreen of a mobile electronic device, the method comprising steps of:

touching a touch-sensitive hotspot displayed on the touchscreen of the mobile electronic device; and

touching a touch-sensitive application icon displayed on the touchscreen of the mobile electronic device in order to launch the application.

11. The method as claimed in claim 10 wherein the application is launched by first touching and releasing the hotspot and then touching and dragging the application icon for the selected application at least partially onto the hotspot.

12. The method as claimed in claim 10 wherein the selected application is launched by touching the hotspot and, while the hotspot is still being touched, touching and dragging the application icon at least partially into an activation zone surrounding the hotspot that is being touched.

13. The method as claimed in claim 10 wherein the selected application is launched by touching and releasing the hotspot and then touching the application icon.

14. The method as claimed in claim 10 wherein the selected application is launched by touching the hotspot, and while the hotspot is still being touched, touching the application icon.

15. The method as claimed in claim 10 wherein the step of touching the touch-sensitive hotspot comprises dragging the hotspot to at least partially overlap the application icon to thereby launch the application.

16. The method as claimed in claim 10 wherein the step of touching the touch-sensitive hotspot comprises dragging the hotspot so that an activation zone surrounding, and movable with, the hotspot at least partially overlap the application icon to thereby cause the application to launch.

17. The method as claimed in claim 10 wherein a plurality of application icons are arranged onscreen such that application icons corresponding to applications that are more frequently launched have more direct access to the hotspot than application icons corresponding to applications that are less frequently launched.

18. The method as claimed in claim 10 further comprising a step of configuring at least one of a virtual inertia parameter, a virtual friction parameter and a virtual collision-elasticity parameter in order to control motion behaviour of the onscreen application icons when the icons are dragged or when the icons collide.

19. A computer program product comprising code which, when loaded into memory and executed on a processor of a mobile electronic device, is adapted to display a user interface on a touchscreen of the mobile electronic device, the user interface presenting both a touch-sensitive application icon corresponding to an application and a touch-sensitive hotspot for launching the application.

20. The computer program product as claimed in claim 19 wherein the code is further adapted to display an activation radius surrounding the hotspot.

21. The computer program product as claimed in claim 19 wherein the code is further adapted to launch the application when the hotspot is touched and released and then the application icon is touched and dragged onto the hotspot.

22. The computer program product as claimed in claim 19 wherein the code is further adapted to launch the application when the hotspot is touched and, while the hotspot is still being touched, the application icon is touched and dragged into the activation radius surrounding the hotspot.

23. The computer program product as claimed in claim 19 wherein the selected application is launched by touching and releasing the hotspot and then touching the application icon.

24. The computer program product as claimed in claim 19 wherein the selected application is launched by touching the hotspot, and while the hotspot is still being touched, touching the application icon.

25. The computer program product as claimed in claim 19 further comprising a step of displacing icons onscreen when dragged or when collisions occur between icons based on at least one of a virtual inertia parameter, a virtual friction parameter and a virtual collision-elasticity parameter.
