Abstract

A user interface is animated and configurable to optimize, facilitate and simplify displaying on a display device and exploring via user input a hierarchy of information accessible by an electronic device.

Claims

1. A user interface comprising:

a plurality of nodes organized into a hierarchy of information wherein at least one node is a focus node and wherein nodes contained inside the focus node form a first sub-hierarchy of nodes in a view;

an aggregator mechanism to associate a visual cue with a node in the view, the visual cue to indicate the node comprises a second sub-hierarchy having hidden nodes, wherein the hidden nodes are too small to be displayed in the view; and

a display to render the plurality of nodes and the visual cue in the view.

2. The user interface of claim 1, wherein the visual cue to further indicate the second sub-hierarchy is completely hidden.

3. The user interface of claim 2, wherein the visual cue comprises a convex shape.

4. The user interface of claim 2, wherein the node comprises other nodes, all of which are too small to be displayed.

5. The user interface of claim 1, wherein the visual cue to further indicate the second sub-hierarchy is partially hidden.

6. The user interface of claim 5, wherein the cue is concave shape.

7. The user interface of claim 5, wherein the node in the view associated with the visual cue contains other nodes, some of which are too small to be displayed.

8. The user interface of claim 1, further comprising a second visual cue to indicate a second node contains only visible nodes.

9. The user interface of claim 8, wherein the second visual cue has a flat shape.

10. The user interface of claim 8, further comprising a third visual cue to indicate a third node contains no hidden sub-hierarchy and is also empty and a leaf node.

11. The user interface of claim 1, further comprising a second visual cue to indicate a second node comprises visible nodes and hidden nodes.

12. The user interface of claim 1, wherein the visual cue comprises a color or symbol.

13. The user interface of claim 1 wherein a node shape, color, or symbol, or combination to depict the absence or presence of additional information in the hierarchy of information.

14. The user interface of claim 1, further comprising an adjustable view angle to affect a perceived viewing perspective in three dimensional space.

15. The user interface of claim 1, further comprising at least one adjustable parameter to facilitate exploration, wherein the adjustable parameter to affect the quantity of nodes displayed or the style of visual cues applied by the aggregator mechanism, or both.

16. The user interface of claim 15, wherein the user interface to accept an input to adjust the adjustable parameter.

17. The user interface of claim 15, wherein the adjustable parameter is selected from the group consisting of view size, minimum node size, focus-to-view ratio and default maximum leaf size.

18. The user interface of claim 17, wherein focus-to-view ratio is the selected adjustment and is provided via a slider incorporated on a display screen.

19. The user interface of claim 15, wherein changes to the selected parameter to result in a change of a specified node'"'"'s visual cue.

20. The user interface of claim 19, wherein a change in the selected adjustable parameter results in at least one node having a visual cue changes, and wherein the visual cue changes to a shape selected from the group consisting of convex, concave and flat.

21. A user interface comprising:

a plurality of nodes organized into a hierarchy of information wherein at least one node is a focus node and wherein nodes contained inside the focus node form a sub-hierarchy of nodes in a view;

an aggregator means to associate at least one visual cue to a node in the view, the visual cue to indicate the node comprises a second sub-hierarchy of hidden nodes, wherein the hidden nodes are too small to be displayed in the view;

a display to render the nodes in the view according to their associated visual cue; and

interface controls to accept input, wherein the user interface system to change focus to a destination focus node in the hierarchy based on the input.

22. The user interface of claim 21, wherein the input originates at a pointing device.

23. The user interface of claim 22, wherein the input describes a click event on a node around the focus node, wherein the user interface to shrink the visible space based on the input.

24. The user interface of claim 22, wherein the input describes a user click event at a node outside the focus node, and wherein the user interface to migrate or translate the visible space based on the input.

25. The user interface of claim 22, wherein the input describes a user click event at a node inside the focus node, and wherein the user interface to enlarge the visible space associated with the node based on the input.

26. The user interface of claim 22, wherein a transition is shown in the view to animate the change of the focus node to the destination focus node based on the input.

27. The user interface of claim 26, wherein the destination focus node is substantially centered in the view after the transition is shown in the view to animate the change of the focus node to the destination focus node.

28. The user interface of claim 27, wherein the user interface also having an adjustment for animation speed factor.

29. The user interface of claim 27, wherein the transition to animate the change of the focus node to the destination focus node is a linear straight-line transition.

30. The user interface of claim 27, wherein the transition to animate the change of the focus node to the destination focus node is non-linear transition having a non-linear speed.

31. The user interface of claim 27, wherein the transition to animate the change of the focus node to the destination focus node is combination of translating and morphing.

32. The user interface of claim 31, wherein the transition to indicate the direction and length of a vector from the newly selected destination focus node to the focus node.

33. The user interface of claim 27, wherein the user interface to further include an animation frame count that sets number of frames to use in the transition.

34. The user interface of claim 33, wherein the animation frame count is automatically configured based on system memory, processor speed.

35. The user interface of claim 33, wherein the destination focus node'"'"'s position and size are computed relative to the focus node and a vector from the destination focus node'"'"'s position to the focus node position is computed and divided by the animation frame count to determine whether or not it exceeds the size of the view.

36. The user interface of claim 35, wherein the divided value is greater than the size of the view and a morphing animation is used to symbolize the long transition.

37. The user interface of claim 35, wherein the divided value is less than the size of the view and the vector is broken down into a discrete amount of steps of which the destination focus node'"'"'s position and size is progressively adjusted to reach those of the focus node.

38. A user interface system comprising:

means for organizing a plurality of nodes into a hierarchy of information wherein at least one node is a focus and the nodes contained inside the focus form a sub-hierarchy of nodes in a view;

an aggregator means to apply at least one visual cue with a node in the view, the visual cue to indicate the node comprises a second sub-hierarchy of hidden nodes, wherein the hidden nodes are too small to be displayed in the view;

a display to render the nodes in the view according to the visual cue applied by the aggregator mechanism; and

at least one adjustable parameter to affect a change to the number of nodes displayed or the visual cues applied by the aggregator mechanism;

wherein the user interface system to allow a destination node in the hierarchy to become the focus, based on input from the user interface system.
