Abstract

A computer system displays: a view window including an initial portion of a document, a scroll icon at an initial scroll icon location on the display, and a marker icon that is distinct from the scroll icon. The computer system detects a scrolling input and in response moves the scroll icon to a target scroll icon location on the display wherein the target scroll icon location corresponds to a target portion of the document. In some embodiments, the computer system scrolls the document towards the target portion of the document and concurrently moves the marker icon towards a target marker icon location on the display that is proximate to the target scroll icon location, where the scrolling speed of the document is determined based on the distance between the marker icon and the scroll icon.

Claims

1. A computer-implemented method, comprising:

at a computer system having one or more processors, memory and a display;

displaying a representation of an entire ordered set of data items, the entire ordered set of data items including an initial subset of data items that is initially a currently selected subset of data items;

wherein the subset comprises two or more data items;

displaying, in a view window for indicating a currently selected subset of data items during a scrolling, a scroll icon at an initial scroll icon location wherein the initial scroll icon location corresponds to the initial subset of data items;

detecting a scrolling input with respect to the entire ordered set of data items;

in response to detecting the scrolling input;

moving the scroll icon to a target scroll icon location on the display, wherein the target scroll icon location corresponds to a target subset of data items from the entire ordered set of data items; and

automatically scrolling, without user intervention, through data items of the entire ordered set of data items at a variable scrolling speed, wherein the scrolling includes sequentially displaying, in the view window, a sequence of currently selected subsets of data items from the entire ordered set of data items, and

the scrolling speed for scrolling from one currently selected subset of data items to a next selected subset of data items in the sequence is determined based on a distance between the currently selected subset of data items and the target subset of data items in the entire ordered set of data items;

wherein the scrolling includes continuing to scroll through the ordered set of data items after moving the scroll icon to the target scroll icon location until the currently selected subset of data items displayed in the view window includes the target subset of data items.

2. The method of claim 1, wherein the scrolling speed is determined such that:

a maximum scrolling speed is determined based on a maximum distance between the currently selected subset of data items and the target subset of data items in the entire ordered set of data items;

when the scrolling speed is less than the maximum scrolling speed, the scrolling speed increases and a rate at which the scrolling speed is increasing is monotonically increasing; and

upon reaching the maximum scrolling speed, the scrolling speed decreases and a rate at which the scrolling speed is decreasing is monotonically increasing.

3. The method of claim 1, wherein the scroll icon includes a first navigation button and a second navigation button and the method further comprises:

in response to detecting a selection of the first navigation button, scrolling through the data items in a first direction such that a first alternate subset of the data items becomes the currently selected subset; and

in response to detecting a selection of the second navigation button, scrolling through the data items in a second direction opposite the first direction such that a second alternate subset of the data items becomes the currently selected subset of the data items, wherein the first alternate subset of the data items is distinct from the second alternate subset of the data items.

4. The method of claim 3, wherein:

scrolling through the data items in the first direction such that the first alternate subset of the data items becomes the currently selected subset includes shifting the data items in the first direction by a predefined amount; and

scrolling through the data items in the second direction such that the second alternate subset of the data items becomes the currently selected subset includes shifting the data items in the second direction by the predefined amount.

5. The method of claim 4, wherein shifting the data items by the predefined amount corresponds to shifting the data items so that data items that were previously included in the currently selected subset are no longer in the currently selected subset.

6. The method of claim 1, further comprising:

detecting a reset input;

in response to the reset input, displaying a reset icon at the initial scroll icon location, wherein the reset icon is distinct from the scroll icon;

detecting a confirmation input; and

in response to the confirmation input, scrolling the data items so that the initial subset of data items becomes the currently selected subset of the data items.

7. The method of claim 6, wherein moving the scrolling icon includes moving the scrolling icon within a predefined region, the reset input includes moving the scrolling icon outside of the predefined region, and the confirmation input includes a user input received while the scrolling icon is outside of the predefined region.

8. The method of claim 1, further comprising:

displaying a stopper icon at a stopper icon location on the display, wherein the scroll icon is configured to move along a predefined path between a path start location and the stopper icon location, and the stopper icon location is automatically determined in accordance with a size of the ordered set of data items relative to a size of the currently selected subset.

9. The method of claim 8, wherein when the scrolling input includes dragging the scrolling icon beyond the stopper icon, the target subset of the data items is a final subset of the data items.

10. The method of claim 8, wherein the stopper icon location is determined such that the length of the predefined path is less than or equal to a maximum path length.

11. A computer system, comprising:

one or more processors;

memory; and

one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including instructions to;

display a representation of an entire ordered set of data items, the entire ordered set of data items including an initial subset of data items that is initially a currently selected subset of data items;

wherein the subset comprises two or more data items;

display, in a view windows for indicating a currently selected subset of data items during a scrolling, a scroll icon at an initial scroll icon location wherein the initial scroll icon location corresponds to the initial subset of data items;

detect a scrolling input with respect to the entire ordered set of data items;

in response to detecting the scrolling input;

automatically move the scroll icon, without user intervention, to a target scroll icon location on the display, wherein the target scroll icon location corresponds to a target subset of data items from the ordered set of data items; and

scroll through data items of the entire ordered set of data items at a variable scrolling speed, wherein the scrolling includes sequentially displaying, in the view window, a sequence of currently selected subsets of data items from the entire ordered set of data items, and

the scrolling speed for scrolling from one currently selected subset of data items to a next selected subset of data items in the sequence is determined based on a distance between the currently selected subset of data items and the target subset of data items in the entire ordered set of data items;

wherein the scrolling includes continuing to scroll through the ordered set of data items after moving the scroll icon to the target scroll icon location until the currently selected subset of data items displayed in the view window includes the target subset of data items.

12. The computer system of claim 11, wherein the scrolling speed is determined such that:

a maximum scrolling speed is determined based on a maximum distance between the currently selected subset of data items and the target subset of data items in the entire ordered set of data items;

when the scrolling speed is less than the maximum scrolling speed, the scrolling speed increases and a rate at which the scrolling speed is increasing is monotonically increasing; and

upon reaching the maximum scrolling speed, the scrolling speed decreases and a rate at which the scrolling speed is decreasing is monotonically increasing.

13. The computer system of claim 11, wherein the scroll icon includes a first navigation button and a second navigation button, and wherein the one or more programs further include instructions that:
