Abstract

One aspect of the invention relates to techniques for increasing the displayable font size while retaining a wide text line of information on small information displays. In one embodiment, the inventive technique leverages the wider diagonal (in device dimensions) for text viewing and combine this form of display with a horizontal (in text dimensions) scrolling feature i.e. scrolling text along the diagonal of the device'"'"'s display. Vertical context (in text dimensions) is maintained by adding a constant-offset look-ahead and look-back line above the primary diagonal focus area. Another embodiment bends the text along two edges of the display area to leverage the fact that the lengths of the two sides are even longer than the length of the screen diagonal. In both configurations, one can retain a large font size without sacrificing the number of characters displayed per line.

Claims

1. A method comprising rendering a text for display on a display device, wherein the text is rendered on the display device in parallel to a diagonal of the display device.

2. The method of claim 1, further comprising scrolling the rendered text along the diagonal of the display device.

3. The method of claim 1, further comprising rendering a look ahead context and a look-back context for display on the display device.

4. The method of claim 3, wherein the look ahead context and the look-back context are rendered in fonts having at least one different font characteristic.

5. The method of claim 4, wherein the font characteristic is a font size.

6. The method of claim 3, wherein the text, the look ahead context and the look-back context are scrolled to maintain a constant offset between the text and the look ahead context and the look-back context.

7. A method comprising rendering a text for display on a display device, wherein the text is rendered on the display device along a curved line spanning diagonally across the display device.

8. A computer readable medium embodying a set of instructions, the set of instructions, when executed by one or more processors causing the one or more processors to render a text for display on a display device, wherein the text is rendered on the display device in parallel to a diagonal of the display device.

9. The computer readable medium of claim 8, wherein the computer readable medium further comprises instructions for scrolling the rendered text along the diagonal of the display device.

10. The computer readable medium of claim 8, wherein the computer readable medium further comprises instructions for rendering a look ahead context and a look-back context for display on the display device.

11. The computer readable medium of claim 10, wherein the look ahead context and the look-back context are rendered, in fonts having at least one different font characteristic.

12. The computer readable medium of claim 11, wherein the font characteristic is a font size.

13. The computer readable medium of claim 8, wherein the computer readable medium further comprises instructions for scrolling the text, the look ahead context and the look-back context to maintain a constant offset between the text and the look ahead context and the look-back context.

14. A computer readable medium embodying a set of instructions, the set of instructions, when executed by one or more processors causing the one or more processors to render a text for display on a display device, wherein the text is rendered on the display device along a curved line spanning diagonally across the display device.

15. A computerized system comprising:

a. Display device;

b. A central processing unit and

c. A memory storing a set of instructions, the set of instructions, when executed by the central processing unit causing the central processing unit to render a text for display on a display device, wherein the text is rendered on the display device in parallel to a diagonal of the display device.

16. The computer system of claim 15, wherein the memory further stores instructions for scrolling the rendered text along the diagonal of the display device.

17. The computer system of claim 15, wherein the memory further stores instructions for rendering a look ahead context and a look-back context for display on the display device.

18. The computer system of claim 17, wherein the look ahead context and the look-back context are rendered in fonts having at least one different font characteristic.

19. The computer system of claim 18, wherein the font characteristic is a font size.

20. The computer system of claim 17, wherein the computer readable medium further comprises instructions for scrolling the text, the look ahead context and the look-back context to maintain a constant offset between the text and the look ahead context and the look-back context.

21. A computerized system comprising:

a. Display device;

b. A central processing unit; and

c. A memory storing a set of instructions, the set of instructions, when executed by one or more processors causing the one or more processors to render a text for display on the display device, wherein the text is rendered on the display device along a curved line spanning diagonally across the display device.

22. A mobile device, comprising:

a. a display;

b. a sensing unit operable to sense a user input;

c. a processing unit operable to process the user input; and

d. a display controller, rendering a text on the display device in parallel to a diagonal of the display.
