Abstract

Disclosed is the presentation of text data on a high-resolution display screen using an image, which includes nonlinear (3D) surface undulation and viewing perspective. This presentation results in variations of character size, rotation, and aspect across the screen. Additionally, positional cues, and coloration gradations may be added. As will be shown, all of this assists human readability and reduces fatigue.

Claims

1. A method wherein the contents of an originating textual electronic document page is mapped onto a simulated undulating topology, as if viewed at a perspective, and then displayed on a screen.

2. The method of claim 1, wherein said undulating topology, as if viewed at a perspective, includes a background image also viewed at a perspective and appearing to be similarly undulated.

3. The method of claim 2, wherein the background is colored in a light blue or pastel.

4. The method of claim 2, wherein the background image contains spectral highlights, as if the display screen is being illuminated from a selected angle.

5. The method of claims 1, wherein the undulating topology and perspective simulate the reading of a book or paper page.

6. The method of claim 1, wherein a sequence of said screens are viewed to simulate the reading of a multi-page document or book.

7. The method of claim 6, wherein the screen sequence alternates simulations of left and right side page undulations possibly including left and right side perspective.

8. The method of claim 1, wherein the display is on a screen having more than 800,000 pixels.

9. The method of claim 1, wherein the screen is in portrait configuration and is thereby taller than it is wide.

10. The method of claim 1, wherein each screen displayed page of a sequence of pages may be altered by one of being mapped onto a differing topology, viewed, as if from a differing perspective, or having a different background.

11. The method of claims 2, wherein the undulating topology and perspective simulate the reading of a book or paper page.

12. The method of claim 2, wherein a sequence of said screens are viewed to simulate the reading of a multi-page document or book.

13. The method of claim 2, wherein the display is on a screen having more than 800,000 pixels.

15. The method of claim 2, wherein each screen displayed page of a sequence of pages may be altered by one of being mapped onto a differing topology, viewed, as if from a differing perspective, or having a different background.

16. The method of claim 1, wherein the mapping is accomplished by the steps of:

(a) selecting an array of points in the essentially rectilinear originating document;

(b) associating with each of said array points information which indicates the translation, sizing and rotation of a character at the array point location if it were translated onto a selected undulating, perspective viewed surface;

(c) for individual characters in the originating document, utilizing the data of proximate array points to interpolate the appropriate translation, sizing, and rotation values appropriate for that character;

(d) mapping said character onto the display screen using said interpolated translation, sizing and rotation values of that character; and

(e) repeating the steps for each character to be displayed for reading.

17. The method of claim 1, wherein the character mapping is created using one or more of affine transforms, curves defined by parametric formulas, interpolation, and scaling, where each character of text is scaled, rotated, and translated using the composite transform calculated for that character and then rendered using application tools.

18. The method of claim 1, implemented in a computer application wherein a person viewing documents may select a presentation style other than conventional rectilinear display.

19. The method of claim 18, wherein the presentation varies between pages to avoid reader fatigue.

14. The method of 2, wherein the screen is in portrait configuration and is thereby taller than it is wide.
