Abstract

A method and system for re-marginating content displayed on a display screen of a computing device when upon receiving indication of an object superposed on the display screen content, a “handedness” preference of the reader/observer can be determined. In one embodiment, the content comprises display of one page in a series of digitally constructed pages. A keep out margin is calculated based on position of the object. Content is then re-flowed or line-wrapped about that keep out margin, to counteract any obscuration of displayed content. The line-wrapping of the content around the keep out margin is accomplished while maintaining a plurality of text attributes of the content. The line-wrapping 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 display of one page in a series of digitally constructed pages;

determining a handedness preference based on a position of the object on the content;

calculating a location of a keep out margin for the content, the margin being located based on the handedness preference such that the content is viewable as rendered to a side thereof;

in response to receiving the indication of the object superposed on the content rendered on the display screen, automatically calculating the keep out margin based on a shape and a size of the superposed object, the keep out margin establishing a minimum-sized keep out zone to a side of the superposed object, wherein the keep out margin spans a vertical length of the display screen;

re-marginating the content by line-wrapping lines of the content about the keep out margin while maintaining a plurality of text attributes of the content; and

reconstructing a next one of the series of pages for display in accordance with the remargination by including at least a portion of the line-wrapped content thereinto.

2. The method of claim 1 wherein the content comprises text content.

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

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

5. The method of claim 1 wherein the keep out margin is visually rendered.

6. The method of claim 5 wherein the visual rendering comprises one of:

a line depth visually contrasting with the content, a color different from the content and a graphic element having visually observable fluctuating intensity.

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

a thumb, a stylus and a finger digit.

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

9. 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.

10. The method of claim 1 wherein the next page as reconstructed includes at least a last line of the content existing prior to the re-margination.

11. The method of claim 1, wherein the handedness preference is determined based on a time duration of the object remaining in contact with the display screen.

12. A non-transitory computer-readable 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 display of one page in a series of digitally constructed pages;

determining a handedness preference based on a position of the object on the content;

calculating a location of a keep out margin for the content, the margin being located based on the handedness preference such that the content is viewable as rendered to a side thereof;

in response to receiving the indication of the object superposed on the content rendered on the display screen, automatically calculating the keep out margin based on a shape and a size of the superposed object, the keep out margin establishing a minimum-sized keep out zone to a side of the superposed object, wherein the keep out margin spans a vertical length of the display screen;

re-marginating the content by line-wrapping lines of the content about the keep out margin while maintaining a plurality of text attributes of the content; and

reconstructing a next one of the series of pages for display in accordance with the re-margination by including at least a portion of the line-wrapped content thereinto.

13. 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 display of one page in a series of digitally constructed pages;

determine a handedness preference based on a position of the object on the content;

calculate a location of a keep out margin for the content, the margin being located based on the handedness preference such that the content is viewable as rendered to a side thereof;

in response to receiving the indication of the object superposed on the content rendered on the display screen, automatically calculate the keep out margin based on a shape and a size of the superposed object, the keep out margin establishing a minimum-sized keep out zone to a side of the superposed object, wherein the keep out margin spans a vertical length of the display screen;

re-marginate the content by line-wrapping lines of the content about the keep out margin while maintaining a plurality of text attributes of the content; and

reconstruct a next one of the series of pages for display in accordance with the re-margination by including at least a portion of the line-wrapped content thereinto.

14. The computing device of claim 13 wherein the content comprises text content.

15. The computing device of claim 14 wherein the content further comprises one or more images interspersed among the text content.

16. The computing device of claim 13 wherein the object is superposed over a periphery of the content rendered on the display screen.

17. The computing device of claim 13 wherein the keep out margin is visually rendered.

18. The computing device of claim 17 wherein the visual rendering comprises one of:

a line depth visually contrasting with the content, a color different from the content and a graphic element of fluctuating intensity.

19. The computing device of claim 13 wherein the object superposed on the content is one of:

a thumb, a stylus and a finger digit.

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

21. The computing device of claim 13 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.
