Abstract

Review systems and methods facilitate active reading by providing a flexible environment in which users can examine documents. A review system can comprise a virtual workspace, a document view region, a preview region, and optional document objects. The virtual workspace can simulate a desktop or other physical workspace. The document view region can display a portion of an open document at a magnification sufficient for reading. The preview region can display the document at a magnification sufficient to enable the general layout of the entire document to be determined. The document objects can be created from the document through tools of the review system. These document objects can be independently moveable throughout the virtual workspace as needed to facilitate the user'"'"'s active reading process.

Claims

1. A method comprising:

11. The method of claim 1, wherein the document preview region is configured to guide navigation of the document in the document view region;

and

wherein, in response to receiving a selection of a preview portion of the document in the document preview region, the document view region displays the preview portion of the document.

12. The method of claim 11, wherein the document preview region is configured to display the entire document simultaneously.

13. The method of claim 1, further comprising receiving a collapse gesture to invoke the collapse command.

14. The method of claim 1, further comprising expanding the intermediate portion of the document in response to an uncollapse command.

15. The method of claim 14, wherein the uncollapse command comprises an uncollapse gesture of an upward swiping over the intermediate portion of the document.

16. The method of claim 1, further comprising:

displaying a first viewable portion of the document in the document view region, wherein a hidden portion of the document is hidden from the document view region;

receiving an annotation input;

creating an annotation object at an annotation location in the virtual workspace outside of the document, in response to receiving the annotation input, the annotation object comprising the annotation input;

receiving a selection of a second viewable portion of the document within the document view region;

providing a graphical link to the second viewable portion of the document;

modifying the document view region to hide the second viewable portion of the document from the document view region;

receiving a selection of the graphical link; and

modifying the document view region to display the second viewable portion of the document in response to the selection of the graphical link.

17. The method of claim 1, wherein the document is a first document, the method further comprising:

displaying a second document in a second document view region of the virtual workspace;

receiving a linking gesture indicating a first linking section in the first document and a second linking section in the second document;

displaying a first graphical link proximate the first linking section in the first document, in response to the linking gesture;

displaying a second graphical link proximate the second linking section in the second document, in response to the linking gesture;

receiving a selection of the first graphical link; and

modifying the second document view region to make the second linking section in the second document visible in the second document view region, in response to the selection of the first graphical link, if the second linking section in second document is not visible in the second document view region at the time of the selection of the first graphical link.

18. The method of claim 1, further comprising:

a physical touch interface for the virtual workspace; and

detecting a touch on the touch interface.

19. The method of claim 1, wherein placement of the first excerpt object is independent of the document and moveable about the virtual workspace.
