Abstract

At least a portion of a plurality of formatting variables associated with an electronic document are modified based in part upon optimized formatting values. A user may specify values for one or more user-modifiable formatting variables. Based on the user data thus specified, at least a portion of the plurality of formatting variables are modified according to corresponding optimized formatting values. The electronic document is then formatted in accordance with the modified formatting variables and provided for display. The user-modifiable variables may comprise a font reference variable and/or a display form factor variable. In this manner, the present invention optimizes readability of electronic documents while still accommodating user preferences for displaying such documents.

Claims

1. In a computer-based device, a method for formatting a document for presentation on a display of the computer-based device, wherein format of the document is controlled by a plurality of formatting variables, the method comprising steps of:

a) receiving user data specifying a value for at least one user-modifiable formatting variable of the plurality of formatting variables the at least one user-modifiable formatting variable including a font reference variable; and

b) in response to step a) modifying at least a portion of the plurality of formatting variables, other than the variable specified in a), such that the modified variables are optimized for readability;

wherein the value specified by the user data for the user-modifiable formatting variable comprises a non-numeric large setting and a non-numeric small setting.

2. The method of claim 1, further comprising steps of:

formatting the document in accordance with the modified formatting variables; and

providing the document for presentation on the display.

3. A computer-readable medium having stored thereon computer-executable instructions for performing the steps of claim 2.

4. The method of claim 1, wherein the value specified by the user data for any one of the at least one user-modifiable variable comprises any one of a predetermined set of variable values.

5. The method of claim 1, wherein the value specified by the user data for the font reference variable comprises either a font value of “

Large” and

a font value of “

Small.”

6. The method of claim 1, wherein the plurality of formatting variables comprises any of a serif variable, a leading variable, a justification variable and a language variable.

7. The method of claim 6, wherein a value for the leading variable optimized for readability comprises any value within a range of 10 to 20 percent.

8. An apparatus comprising:

a processor;

a display coupled to the processor;

a user interface selection device coupled to the processor; and

a storage device, coupled to the processor, comprising instructions, executable by the processor, for performing steps of;

a) receiving user data, via the user interface selection device, specifying a value for at least one user-modifiable formatting;

variable of a plurality of formatting variables used to control format of a document for display,

the at least one user-modifiable formatting variable including a display form factor variable; and

b) in response to step a) modifying at least a portion of the plurality of formatting variables, other than the variable specified in an such that the modified variables are optimized for readability;

wherein the value specified by the user data for the display form factor variable comprises one of a plurality of screen resolution settings.

9. The apparatus of claim 8, the storage device further comprising instructions for performing steps of:

formatting the document in accordance with the modified formatting variables; and

providing the document for presentation on the display.

10. A handheld display device comprising the apparatus of claim 9.

11. A desktop display device comprising the apparatus of claim 9.

12. The apparatus of claim 8, wherein the value specified by the user data for any one of the at least one user-modifiable variable comprises any one of a predetermined set of variable values.

13. The apparatus of claim 8, wherein the plurality of formatting variables comprises any of a serif variable, a leading variable, a justification variable and a language variable.

14. The apparatus of claim 13, wherein a value for the leading variable optimized for readability comprises any value within a range of 10 to 20 percent.

15. An apparatus comprising:

a processor;

a handheld display coupled to the processor; and

a storage device, coupled to the processor, comprising instructions, executable by the processor, for performing steps of;

a) receiving a value of a display form factor variable indicative of display characteristics of the display; and

b) in response to step a) modifying at least a portion of a plurality of formatting variables, other than the display form factor variable specified in a), such that the modified variables are optimized for readability.

16. The apparatus of claim 15, the storage device further comprising instructions for performing steps of:

formatting the document in accordance with the modified formatting variables; and

providing the document for presentation on the display.

17. The apparatus of claim 16, wherein the handheld display has a resolution of 240 pixels by 320 pixels.

18. The apparatus of claim 15, wherein the value of the display form factor variable indicates a resolution of the display.

19. The apparatus of claim 15, wherein the plurality of formatting variables comprises any of a font size variable, a font face variable, a serif variable, a headings variable, a leading variable, a line length variable, a left margin variable, a right margin variable, a top margin variable, a bottom margin variable, an indents variable, a hyphenation variable, a justification variable and a language variable.

20. The apparatus of claim 19, wherein a value for the font size variable optimized for readability comprises any value within a range of 10 to 18 points.

21. The apparatus of claim 19, wherein the font face variable optimized for readability specifies either of a sans serif font or a serif font.

22. The apparatus of claim 19, wherein a value for the leading variable optimized for readability comprises any value within a range of 10 to 20 percent.

23. A computer-readable medium having stored thereon a data structure comprising:

a plurality of formatting variables for use in formatting a document for display via a computer-based display, the plurality of formatting variables comprising at least one user-modifiable formatting variable and a screen resolution variable; and

optimized formatting values corresponding to at least a portion of the plurality of formatting variables,

wherein the portion of the plurality of formatting variables is modified, other than the at least one user-modifiable form at variable, based on user specified data for the at least one user modifiable formatting variable, and further based on the screen resolution variable such that the modified variables are optimized for readability.
