Abstract

An automatic scrolling and paging function is provided for use with an object/text editor or a browser, in which either scrolling or paging is automatically performed at a variable speed. A delay time is set as a parameter for control of the display; automatic display of the document is commenced by displaying a first portion of the document; a subsequent portion of the document is displayed after expiration of the delay time; and the display of portions of the document is iterated until the entire document has been displayed. The delay time is reset during the automatic display, thereby changing the rate at which successive portions of the document are displayed. The delay time may depend upon the location of the portion of the document; accordingly, successive portions of the document may be automatically displayed at a varying rate.

Claims

1. A method for facilitating display of a document to a user, the document having a plurality of portions, the method comprising the steps of;

(a) setting a delay time as a parameter for control of the display;

(b) commencing an automatic display of the document by displaying a first portion of the document;

(c) displaying a subsequent portion of the document after expiration of the delay time,

(d) iterating step (c) until the entire document has been displayed;

(e) resetting the delay time, during one of steps (b), (c) and (d), thereby changing a rate at which successive portions of the document are displayed; and

(f) setting a display mode as a parameter for control of the display, in accordance with an input from the user, wherein the display mode is one of paging and scrolling and wherein when the display mode is scrolling the first portion is displayed as a page of the document, and each subsequent portion is an additional line of the document.

2. A method according to claim 1, further comprising the step of setting a time increment as an additional parameter for control of the display, and wherein the resetting of the delay time is performed by one of adding the time increment to the delay time and subtracting the time increment from the delay time.

3. A method according to claim 2, wherein the delay time and the time increment are selected by the user, and the resetting of the delay time is performed in accordance with an input from the user.

4. A method according to claim 1, further comprising the step of suspending the automatic display of a subsequent portion of the document, in accordance with an input from the user.

5. A method according to claim 1, wherein each portion of the document has a delay time associated therewith whose length depends upon the location of said portion in the document, so that successive portions of the document are displayed at a varying rate.

6. A method according to claim 1, wherein when the display mode is paging the first portion is displayed as a page of the document, and each subsequent portion is an additional page of the document.

7. A computer-readable storage medium having stored therein instructions for performing an automated method for facilitating display of a document to a user, the document having a plurality of portions, the method comprising the steps of:

(a) setting a delay time as a parameter for control of the display;

(b) commencing an automatic display of the document by displaying a first portion of the document;

(c) displaying a subsequent portion of the document after expiration of the delay time;

(d) iterating step (c) until the entire document has been displayed;

(e) resetting the delay time, during one of steps (b), (c) and (d), thereby changing a rate at which successive portions of the document are displayed; and

(f) setting a display mode as a parameter for control of the display, in accordance with an input from the user, wherein the display mode is one of paging and scrolling, and wherein when the display mode is scrolling the first portion is displayed as a page of the document, and each subsequent portion is an additional line of the document.

8. A computer-readable storage medium according to claim 7, wherein the automated method further comprises the step of setting a time increment as an additional parameter for control of the display, and wherein the resetting of the delay time is performed by one of adding the time increment to the delay time and subtracting the time increment from the delay time.

9. A computer-readable storage medium according to claim 8, wherein the delay time and the time increment are selected by the user, and the resetting of the delay time is performed in accordance with an input from the user.

10. A computer-readable storage medium according to claim 7, wherein the automated method further comprises the step of suspending the automatic display of a subsequent portion of the document, in accordance with an input from the user.

11. A computer-readable storage medium according to claim 7, wherein each portion of the document has a delay time associated therewith whose length depends upon the location of said portion in the document, so that successive portions of the document are displayed at a varying rate.

12. A computer-readable storage medium according to claim 7, wherein when the display mode is paging the first portion is displayed as a page of the document, and each subsequent portion is an additional page of the document.

13. A computer program product comprising instructions for performing an automated method for facilitating display of a document to a user, the document having a plurality of portions, the method including the steps of:

(a) setting a delay time as a parameter for control of the display,

(b) commencing an automatic display of the document by displaying a first portion of the document,

(c) displaying a subsequent portion of the document after expiration of the delay time;

(d) iterating step (c) until the entire document has been displayed;

(e) resetting the delay time, during one of steps (b), (c) and (d), thereby changing a rate at which successive portions of the document are displayed; and

(f) setting a display mode as a parameter for control of the display, in accordance with an input from the user, wherein the display mode is one of paging and scrolling, and wherein when the display mode is scrolling the first portion is displayed as a page of the document, and each subsequent portion is an additional line of the document.

14. A computer program product according to claim 13, wherein the automated method further comprises the step of setting a time increment as an additional parameter for control of the display, and wherein the resetting of the delay time is performed by one of adding the time increment to the delay time and subtracting the time increment from the delay time.

15. A computer program product according to claim 14, wherein the delay time and the time increment are selected by the user, and the resetting of the delay time is performed in accordance with an input from the user.

16. A computer program product according to claim 13, wherein the automated method further comprises the step of suspending the automatic display of a subsequent portion of the document, in accordance with an input from the user.

17. A computer program product according to claim 13, wherein each portion of the document has a delay time associated therewith whose length depends upon the location of said portion in the document, so that successive portions of the document are displayed at a varying rate.

18. A computer program product according to claim 13, wherein when the display mode is paging the first portion is displayed as a page of the document, and each subsequent portion is an additional page of the document.
