Altering a view of a document on a display of a computing device

A method that alters a view of a document comprising:nproviding on a display of a computer processing device an editing view of a document at a zoom level such that input from a user can be received to edit content of the document;receiving a first input from the user requesting to zoom-out the editing view of the document from the zoom level;testing whether a resulting zoom level of the document is less than a threshold zoom level;altering the view of the document to provide a semantic zoom view of the document in response to determining the resulting zoom level is less than the threshold zoom level, wherein the semantic view of the document provides a plurality of thumbnails pages on the display and a heading pane comprising a plurality of headings contained in one or more pages of the document;receiving a second input from the user indicating a selection of one of the plurality of headings in the heading pane; andproviding on the display of the computer processing device a subset of the plurality of thumbnail pages in the thumbnail pane in response to receiving the second input,wherein the subset of the plurality of thumbnail pages comprises a thumbnail page corresponding to the selection of one of the plurality of headings in the heading pane and a plurality of and preceeding and succeeding thumbnail pages to the thumbnail page.

A computer readable medium comprising instructions that when executed cause a computer to:nprovide on a display of the computer processing device an editing view of a document at a zoom level such that input from a user can be received to edit content of the document;receive input from the user requesting to zoom-out the editing view of the document from the zoom level;test whether a resulting zoom level of the document is less than a threshold zoom level;in response to determining the resulting zoom level is less than the threshold zoom level, alter the view of the document to provide a semantic zoom view of the document wherein a plurality of thumbnails pages are provided on the display, and a heading pane comprising a plurality of headings contained in one or more pages of the document;receive a second input from the user indicating a selection of one of the plurality of headings in the heading pane; andprovide on the display of the computer processing device a subset of the plurality of thumbnail pages in the thumbnail pane in response to receiving the second input,wherein the subset of the plurality of thumbnail pages comprises a thumbnail page corresponding to the selection of one of the plurality of headings in the heading pane and a plurality of preceding and succeeding thumbnail pages to the thumbnail page.

A system that provides an editing view and a semantic zoom view comprising:na display;an input device configured to receive input, anda processor configured tonusing the display, provide an editing view of a document comprising a page at a zoom level wherein a content of the document can be edited based on input from the input device,receive a first input from the input device indicating a zoom-out request wherein the zoom-out request exceeds a threshold level,using the display, provide a semantic view of the document in response the zoom-out request exceeding the threshold level, the semantic view comprising a plurality of thumbnail pages in a thumbnail pane and a plurality of headings in a heading pane, wherein the plurality of headings are derived from the document,receive a second input from input device indicating a selection of one of the plurality of headings in the heading pane, andusing the display, provide a subset of the plurality of thumbnail pages in the thumbnail pane in response to receiving the second input,wherein the subset of the plurality of thumbnail pages comprises a thumbnail page corresponding to the selection of one of the plurality of headings in the heading pane and a plurality of preceding and succeeding thumbnail pages to the thumbnail page.
