Abstract

Methods, systems, and apparatus, including computer programs encoded on computer storage media for graphically indicating text continuity. One method includes receiving text including a first line of text followed by a second line of text followed by a third line of text and selecting a distinct line beginning and line end of each of the first, second, and third lines of text. The method further includes formatting the text, including setting respective first attribute values for a first appearance attribute, so that, with respect to the first appearance attribute, the text has a continuity of visual appearance from the first line end to the second line beginning, and so that, with respect to the first appearance attribute, no continuity of visual appearance exists from the first line end to either the first line beginning or to the third line beginning, and presenting the formatted text on the output device.

Claims

1. A computer-implemented method, comprising:

receiving input text;

determining that one or more previously-stored formatting settings include a color setting that determines that color appearance attributes will be changed when formatting input text for display on a display device;

formatting the input text according to the color setting to produce output text for display in a window on the display device as successive lines of output text ending at respective line breaks, each successive line of output text immediately following a preceding line of output text,

wherein the formatting includes setting color attribute values for the output text according to the previously-stored color setting so that the successive lines of output text in the window all have a continuity of color appearance across the line breaks separating the lines of text, and so that the successive lines of output text in the window all have no continuity of color appearance between respective adjacent beginning portions of successive lines of output text; and

presenting the formatted successive lines of output text in the window on the display device.

2. A non-transitory computer storage medium encoded with a computer program, the computer program comprising instructions that, when executed by data processing apparatus, cause the data processing apparatus to perform operations comprising:

receiving input text;

determining that one or more formatting settings stored on the data processing apparatus include a color setting that determines that color appearance attributes will be changed when formatting input text for display on a display device;

formatting the input text according to the color setting to produce output text for display in a window on the display device as successive lines of output text ending at respective line breaks, each successive line of output text immediately following a preceding line of output text,

wherein the formatting includes setting color attribute values for the output text according to the color setting previously stored on the data processing apparatus so that the successive lines of output text in the window all have a continuity of color appearance across the line breaks separating the lines of text, and so that the successive lines of output text in the window all have no continuity of color appearance between respective adjacent beginning portions of successive lines of output text; and

presenting the formatted successive lines of output text in the window on the display device.

3. A system for formatting text to assist a user in reading text, the system comprising:

a display device;

one or more computers coupled to the display device and configured to perform operations comprising;

determining that one or more formatting settings stored on the one or more computers include a color setting that determines that color appearance attributes will be changed when formatting text for display on the display device;

receiving input text;

formatting the input text according to the color setting to produce output text for display in a window on the display device as successive lines of output text ending at respective line breaks, each successive line of output text immediately following a preceding line of output text,

wherein the formatting includes setting color attribute values for the output text according to the color setting previously stored on the one or more computers so that the successive lines of output text in the window all have a continuity of color appearance across the line breaks separating the lines of text, and so that the successive lines of output text in the window all have no continuity of color appearance between respective adjacent beginning portions of successive lines of output text; and

presenting each formatted successive line of output text in the window on the display device.

4. The system of claim 3, wherein receiving the input text comprises receiving the input text in the form of pixels in an image, and wherein formatting the input text to produce output text comprises modifying the image itself by setting color values for at least some of the pixels in the image.

5. The system of claim 3, wherein receiving the input text comprises receiving the input text as characters having modifiable attributes, and formatting the input text to produce output text comprises setting respective color values for color attributes of characters of the text.

6. The system of claim 3, wherein the operations further comprise:

receiving the text as unformatted text; and

selecting a position in the text for each respective line break.

7. The system of claim 3, wherein the operations further comprise:

receiving the text as formatted text that includes line breaks; and

maintaining the received line breaks in position when formatting the text.

8. The system of claim 3, wherein:

the window has a left boundary and a right boundary; and

each of the successive lines of text runs in a straight line from the left boundary toward the right boundary, and none of the output text is displayed between any line beginning and the left boundary or between any line end and the right boundary.

9. The system of claim 3, further comprising:

setting color attribute values for the output text, so that the output text has a respective continuity of visual color appearance within each line of the successive lines of output text from a beginning of the line through an end of the line.

10. The system of claim 3, wherein the operations further comprise receiving the color setting from a user of the system before receiving the input text.

11. The system of claim 3, wherein the color setting is a default color setting of the system.

12. The system of claim 3, wherein presenting each formatted successive line of output text on the display device includes presenting each formatted successive line of output text across a display area on the output device from a beginning side of the display area to an opposite ending side of the display area, wherein at each line break the output text continues for reading in an immediately subsequent line of output text that begins at the beginning side of the display area.

13. The system of claim 3, wherein the one or more computers are configured to perform the operations of receiving, formatting, and presenting for an unlimited number of successive lines of text.

14. The system of claim 3, wherein:

the successive lines of output text each have a respective line middle that extends between a line beginning and a line end of the respective line; and

formatting the input text further comprises setting color values for the line middle of each of the successive lines of output text so that each line middle has color values that transition from color values for the respective line beginning to color values for the respective line end.

15. The system of claim 14, wherein the color values in each line middle are chosen according to a non-uniform transition rate from line beginning to line end.

16. The system of claim 14, wherein the successive lines of output text have varying lengths, and wherein the operations further comprise:

determining a respective transition rate for each of the successive lines of output text from the respective lengths of the lines of text; and

determining the color value for each character in the line middle of each of the successive lines of output text from the respective transition rate for the line.

17. The system of claim 3, wherein each line of the successive lines of output text has a middle, and setting color attribute values for the output text comprises setting color attribute values for the middle so that the middle of each successive line of output text is visually different from the beginning portion of the line and from an end portion of the line.

18. The system of claim 3, wherein setting color attribute values for the output text so that the successive lines of text have a continuity of color appearance across the line breaks comprises selecting color values that are within a predetermined threshold distance of each other.

19. The system of claim 3, wherein the display device and the one or more computers are embedded in a single device.

20. The system of claim 3, wherein the color appearances of the beginning portions of the successive lines of output text repeat with a period of two lines and the color appearances of ending portions of the successive lines of output text repeat with a period of two lines.
