Abstract

One example method for navigating a scrollable user interface includes outputting to a display device the scrollable user interface, the scrollable user interface including a scroll-control target. The method further includes receiving a pointer input, and moving a position of a virtual pointer on the scrollable user interface responsive to the pointer input. Responsive to the virtual pointer being within a first region of the scroll-control target, the scrollable user interface is scrolled at a first speed. Responsive to the virtual pointer being within a second region of the scroll-control target, the scrollable user interface is scrolled at a second speed, faster than the first speed.

Claims

1. A method for navigating a scrollable user interface, comprising:

outputting to a display device the scrollable user interface, the scrollable user interface including a scroll-control target;

receiving a pointer input;

moving a position of a virtual pointer on the scrollable user interface responsive to the pointer input;

responsive to the virtual pointer being within a first region of the scroll-control target, scrolling the scrollable user interface at a first speed; and

responsive to the virtual pointer being within a second region of the scroll-control target, scrolling the scrollable user interface at a second speed, faster than the first speed.

2. The method of claim 1, wherein the pointer input comprises a command from a remote control device.

3. The method of claim 1, wherein the pointer input comprises a virtual skeleton derived from one or more depth images captured via a depth camera.

4. The method of claim 1, wherein the pointer input comprises a command from a touch-sensitive device.

5. The method of claim 1, wherein scrolling the scrollable user interface at the first speed further comprises scrolling the scrollable user interface at the first speed responsive to the virtual pointer being in the first region for at least a threshold duration.

6. The method of claim 1, wherein scrolling the scrollable user interface at the second speed further comprises scrolling the scrollable user interface at the second speed responsive to the virtual pointer being in the second region for at least threshold duration.

7. The method of claim 1, wherein the scroll-control target comprises a rectilinear polygon having a center point.

8. The method of claim 7, wherein the first region is closer to the center point than the second region.

9. The method of claim 7, wherein the scroll-control target extends in a horizontal direction across a top or bottom portion of the scrollable user interface, and wherein scrolling the scrollable user interface further comprises scrolling the scrollable interface in a horizontal direction.

10. The method of claim 9, further comprising, responsive to the virtual pointer being within the scroll-control target on a left side of the center point, scrolling the scrollable user interface in a leftward direction, and responsive to the virtual pointer being within the scroll-control target on a right side of the center point, scrolling the scrollable user interface in a rightward direction.

11. The method of claim 7, wherein the scroll-control target extends in a vertical direction across a side portion of the scrollable user interface, and wherein scrolling the scrollable user interface further comprises scrolling the scrollable interface in a vertical direction.

12. The method of claim 11, further comprising, responsive to the virtual pointer being within the scroll-control target above the center point, scrolling the scrollable user interface in an upward direction, and responsive to the virtual pointer being within the scroll-control target below the center point, scrolling the scrollable user interface in a downward direction.

13. The method of claim 7, further comprising, responsive to the virtual pointer being located at the center point of the scroll-control target, freezing the scrollable user interface.

14. The method of claim 7, wherein a scrolling speed of the scrollable user interface increases as a function of a distance of the virtual pointer from the center point.

15. The method of claim 1, wherein the scroll-control target remains in a fixed position regardless of a speed of the scrollable user interface.

16. The method of claim 1, further comprising, responsive to the virtual pointer being moved from the first region to the second region, ramping a speed of the scrolling of the scrollable user interface from the first speed to the second speed.

17. The method of claim 1, wherein scrolling the scrollable user interface at the first speed further comprises outputting to the display device the scrollable user interface at a first, zoomed-in view.

18. The method of claim 17, wherein scrolling the scrollable user interface at the second speed further comprises outputting to the display device the scrollable user interface at a second, zoomed-out view.

19. A method for navigating a scrollable user interface, comprising:

outputting to a display device the scrollable user interface, the scrollable user interface including a scroll-control target;

receiving a virtual skeleton modeled from a depth map, the virtual skeleton including a hand joint;

moving a position of a virtual pointer on the scrollable user interface responsive to a position of the hand joint of the virtual skeleton;

responsive to the virtual pointer being within a first region of the scroll-control target for at least a first threshold duration, scrolling the scrollable user interface at a first speed; and

responsive to the virtual pointer being within a second region of the scroll-control target for at least a second threshold duration, scrolling the scrollable user interface at a second speed, faster than the first speed.

20. A method for navigating a scrollable user interface, comprising:

outputting to a display device the scrollable user interface, the scrollable user interface including a scroll-control target;

receiving a virtual skeleton modeled from a depth map, the virtual skeleton including a hand joint;

moving a position of a virtual pointer on the scrollable user interface responsive to a position of the hand joint of the virtual skeleton;

responsive to the virtual pointer being within a first region of the scroll-control target, scrolling the scrollable user interface at a first speed with a first, zoomed-in view; and

responsive to the virtual pointer being within a second region of the scroll-control target, scrolling the scrollable user interface at a second speed with a second, zoomed-out view, the second speed being faster than the first speed.
