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

responsive to a command to switch from a viewing mode of the scrollable user interface to a scrolling mode of the scrollable user interface, setting an entirety of the content area as a scroll control target;

responsive to a visible pointer being displayed at a first position within the first region of the content area for at least a first threshold duration and without receiving additional pointer input, scrolling the scrollable user interface towards the first edge;

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

moving the visible pointer from the first position to a second position in the scrollable user interface responsive to a position of the hand joint of the virtual skeleton;

responsive to the visible pointer being displayed at the second position within the second region of the content area for at least a second threshold duration and without receiving additional pointer input, scrolling the scrollable user interface towards the second edge; and

responsive to the visible pointer being displayed within the center region, freezing scrolling of the scrollable user interface.

2. The method of claim 1, wherein fixed boundaries of the first region and the second region are visually indicated on the scrollable user interface.

3. The method of claim 1, wherein, in the first region, a speed at which the scrollable user interface is scrolled increases as a distance measured from the visible pointer to the center increases.

4. The method of claim 1, wherein scrolling the scrollable user interface towards the first edge comprises scrolling the scrollable user interface in a leftward direction, and wherein scrolling the scrollable user interface towards the second edge comprises scrolling the scrollable user interface in a rightward direction.

5. The method of claim 1, wherein the first region, the second region, and the center region collectively constitute a horizontal control target, wherein the center region is a first center region, and wherein the scrollable user interface further includes a vertical control target comprising a third region fixed in a fourth dedicated area of the scrollable user interface, a fourth region fixed in a fifth dedicated area of the scrollable user interface, and a second center region between the third region and the fourth region.

6. The method of claim 5, further comprising:

responsive to the visible pointer being displayed within the third region of the vertical control target and without receiving additional pointer input, scrolling the scrollable user interface towards a third edge of the display device;

responsive to the visible pointer being displayed within the fourth region of the vertical control target and without receiving additional pointer input, scrolling the scrollable user interface towards a fourth edge of the display device; and

responsive to the visible pointer being displayed within the second center region of the vertical control target, freezing scrolling of the scrollable user interface.

7. The method of claim 6, wherein scrolling the scrollable user interface towards the third edge comprises scrolling the scrollable user interface in an upward direction, and wherein scrolling the scrollable user interface towards the fourth edge comprises scrolling the scrollable user interface in a downward direction.

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

outputting to a display device having a first edge, a second edge, and a center between the first edge and the second edge, a scrollable user interface including a scroll-control target having a first region fixed in a first dedicated area of the scroll-control target, a second region fixed in a second dedicated area of the scroll-control target and separated from the first region by a displayed fixed boundary, and a center region fixed between the first region and the second region in a dedicated center area of the scroll-control target;

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

displaying a visible pointer at a first position in the scrollable user interface;

moving the visible pointer from the first position to a second position in the scrollable user interface responsive to a position of the hand joint of the virtual skeleton;

responsive to the visible pointer being displayed on a first side of the displayed fixed boundary within the first region of the scroll-control target and without receiving additional pointer input, scrolling the scrollable user interface at a first speed with a first, zoomed-in view towards the first edge;

responsive to the visible pointer being displayed on a second side of the displayed fixed boundary, opposite the first side, within the second region of the scroll-control target and without receiving additional pointer input, scrolling the scrollable user interface at a second speed with a second, zoomed-out view towards the second edge, the second speed being faster than the first speed; and

responsive to the visible pointer being displayed within the center region, freezing scrolling of the scrollable user interface.

9. The method of claim 8, wherein scrolling the scrollable user interface towards the first edge includes scrolling the scrollable user interface in one constrained dimension perpendicular to the first edge.

10. The method of claim 8, wherein, in the first region, the first speed at which the scrollable user interface is scrolled is determined based on a distance measured from the visible pointer to the center.

11. The method of claim 8, wherein scrolling the scrollable user interface towards the first edge comprises scrolling the scrollable user interface in a leftward direction, and wherein scrolling the scrollable user interface towards the second edge comprises scrolling the scrollable user interface in a rightward direction.

12. The method of claim 8, wherein the first region and the second region collectively constitute a horizontal control target, and wherein the scrollable user interface further includes a vertical control target comprising a third region fixed in a third dedicated area of the scroll-control target, and a fourth region fixed in a fourth dedicated area of the scroll-control target.

13. The method of claim 12, further comprising:

responsive to the visible pointer being displayed within the third region of the vertical control target and without receiving additional pointer input, scrolling the scrollable user interface towards a third edge of the display device; and

responsive to the visible pointer being displayed within the fourth region of the vertical control target and without receiving additional pointer input, scrolling the scrollable user interface towards a fourth edge of the display device.

14. The method of claim 13, wherein scrolling the scrollable user interface towards the third edge comprises scrolling the scrollable user interface in an upward direction, and wherein scrolling the scrollable user interface towards the fourth edge comprises scrolling the scrollable user interface in a downward direction.
