Abstract

A method and system for repaginating content displayed on a display screen of a computing device when upon receiving indication of an object superposed on the content. The content comprises display of one page in a series of digitally constructed pages. The repaginated content is re-flowed or line-wrapped around an identified keep out boundary to counteract any obscuration of displayed content. The repagination forces reconstruction of a next one of the series of pages for display.

Claims

1. A method executed in a processor of a computing device, the computing device further including a memory storing instructions and a display screen having touch functionality, the method comprising:

receiving indication of an object superposed on content rendered on the display screen, the content comprising at least display of lines of text in one page of a series of digitally constructed pages;

calculating a keep out boundary around the superposed object on the one page of the series of digitally constructed pages, wherein the keep out boundary is calculated and customized based on a shape and size of the superposed object of a user to establish a minimum-sized keep out zone around the superposed object of the user, the keep out boundary being positioned on the one page such that the content is viewable when rendered outside thereof, wherein the keep out boundary is further customizable via selection of a keep out boundary size from a plurality of keep out boundary size options via a device settings menu;

determining the keep out boundary being visually rendered or invisibly rendered on the display screen by the user via selection of one or more visual rendering options via the device settings menu, wherein the visual rendering options for the keep out boundary include an outline of the keep out boundary of noticeable depth or translucency, a solid or a fluctuating color(s), and a variation in display brightness or contrast relative to the content;

determining a demarcation boundary line to demarcate the content into an upper and a lower content portions based on an extremity of the calculated keep out boundary determined by the shape and size of the superposed object of the user; and

while lines of original text in the upper content portion are unchanged, repaginating the lower content portion by line-wrapping lines of the text around the keep out boundary of the user while maintaining a plurality of text attributes of the lower content portion of the one page of the series of digitally constructed pages;

whereby the repagination forces reconstruction of a next page of the series of digitally constructed pages for display commensurate with including at least a portion of the lower content portion thereinto, wherein the next page of the series of digitally constructed pages comprises at least a last line of text in the lower content portion prior to the repagination.

2. The method of claim 1 wherein the content further comprises one or more images interspersed among the text content.

3. The method of claim 1 wherein the object is superposed over a periphery of the content rendered on the display screen.

4. The method of claim 1 wherein the object superposed on the content is one of:

a thumb, a stylus and a finger digit.

5. The method of claim 1 wherein the computing device comprises an electronic reading device displaying paginated content at the display screen.

6. The method of claim 1 wherein the plurality of text attributes are selected from a group of text attributes consisting of:

a font size, a word spacing, a line spacing, and a font type.

7. The method of claim 1, wherein the extremity of the keep out boundary corresponds to a point on the display screen at which, during a natural reading progression of the content rendered on the display screen, a first portion of the content falls at least partially within the keep out boundary.

8. A non-transitory computer-readable storage medium that stores instructions for a computing device, the computing device including a processor, a memory and a display screen having touch functionality, the instructions being executable by the processor to cause the computing device to perform operations that include:

receiving indication of an object superposed on content rendered on the display screen, the content comprising at least display of lines of text in one page of a series of digitally constructed pages;

calculating a keep out boundary around the superposed object on the one page of the series of digitally constructed pages, wherein the keep out boundary is calculated and customized based on a shape and size of the superposed object of a user to establish a minimum-sized keep out zone around the superposed object of the user, the keep out boundary being positioned on the one page such that the content is viewable when rendered outside thereof, wherein the keep out boundary is further customizable via selection of a keep out boundary size from a plurality of keep out boundary size options via a device settings menu;

determining the keep out boundary being visually rendered or invisibly rendered on the display screen by the user via selection of one or more visual rendering options via the device settings menu, wherein the visual rendering options for the keep out boundary include an outline of the keep out boundary of noticeable depth or translucency, a solid or a fluctuating color(s), and a variation in display brightness or contrast relative to the content;

determining a demarcation boundary line to demarcate the content into an upper and a lower content portions based on an extremity of the calculated keep out boundary determined by the shape and size of the superposed object of the user; and

while lines of original text in the upper content portion are unchanged, repaginating the lower content portion by line-wrapping lines of the text around the keep out boundary of the user while maintaining a plurality of text attributes of the lower content portion of the one page of the series of digitally constructed pages;

whereby the repagination forces reconstruction of a next page of the series of digitally constructed pages for display commensurate with including at least a portion of the lower content portion thereinto, wherein the next page of the series of digitally constructed pages comprises at least a last line of text in the lower content portion prior to the repagination.

9. A computing device comprising:

a memory that stores a set of instructions;

a display screen having touch functionality;

a processor that access the instructions in memory, the processor further configured to;

receive indication of an object superposed on content rendered on the display screen, the content comprising at least display of lines of text in one page in a series of digitally constructed pages;

calculate a keep out boundary around the superposed object on the one page of the series of digitally constructed pages, wherein the keep out boundary is calculated and customized based on a shape and size of the superposed object of a user to establish a minimum-sized keep out zone around the superposed object of the user, the keep out boundary being positioned on the one page such that the content is viewable when rendered outside thereof, wherein the keep out boundary is further customizable via selection of a keep out boundary size from a plurality of keep out boundary size options via a device settings menu;

determine the keep out boundary being visually rendered or invisibly rendered on the display screen by the user via selection of one or more visual rendering options via the device settings menu, wherein the visual rendering options for the keep out boundary include an outline of the keep out boundary of noticeable depth or translucency, a solid or a fluctuating color(s), and a variation in display brightness or contrast relative to the content;

determine a demarcation boundary line to demarcate the content into an upper and a lower content portions based on an extremity of the calculated keep out boundary determined by the shape and size of the superposed object of the user; and

while lines of original text in the upper content portion are unchanged, repaginate the lower content portion by line-wrapping lines of the text around the keep out boundary of the user while maintaining a plurality of text attributes of the lower content portion of the one page of the series of digitally constructed pages;

whereby the repagination forces reconstruction of a next page of the series of digitally constructed pages for display commensurate with including at least a portion of the lower content portion thereinto, wherein the next page of the series of digitally constructed pages comprises at least a last line of text in the lower content portion prior to the repagination.

10. The computing device of claim 9 wherein the content further comprises one or more images interspersed among the text content.

11. The computing device of claim 9 wherein the object is superposed over a periphery of the content rendered on the display screen.

12. The computing device of claim 9 wherein the object superposed on the content is one of:

a thumb, a stylus and a finger digit.

13. The computing device of claim 9 wherein the computing device comprises an electronic reading device displaying paginated content at the display screen.

14. The computing device of claim 9 wherein the plurality of text attributes are selected from a group of text attributes consisting of:

a font size, a word spacing, a line spacing, and a font type.
