Description

ERGONOMIC READER SOFTWARE

BACKGROUND OF THE INVENTION

1. The Field of the Invention The present invention relates generally to software for reading and displaying text files. More particularly, embodiments of the present invention relate to improved reader software that employs display parameters to automatically format a text file in such a way that a user can view the text file as a series of pages, each of which can be displayed in its entirety on the user display screen, thus obviating the need for scrolling or other display manipulation, and making the text file easier for the user to read.

2. The Prior State of the Art

The ubiquitous nature of the internet and the rapid expansion of the types and numbers of web sites accessible via the internet have combined to place a virtual mine of information at the fingertips of anyone possessing a computer and a modem.

Because of the huge volume of information available, and because access to that information is relatively reliable, computer users are spending more and more time at their computers exploring and using web sites. Additionally, the development of user-friendly web 'browsers' which enable a user to quickly and easily navigate the internet and individual web sites has also been a major contributor to the increased usage of computers and the internet. The web browser is a means by which the user can electronically "travel' from one web site to another; the web browser also serves to display the textual and graphical data of the web site on the user's display screen.

While exploring the internet and web sites, computer users are exposed to a wide variety of graphical and textual data. The graphical data, in particular, is often displayed in a rather sophisticated manner; use of media such as video clips and three dimensional pictures and images is not uncommon. The display of textual data, on the other hand, is somewhat problematic.

One of the difficulties with displaying textual data is that the typical web browser is unequipped to display some types of textual data; thus, the user is completely unable to view these text types. The textual data that can be displayed is typically displayed either by the browser itself, or by means of a text reader that is 'plugged in' to the browser and initialized by the browser when the browser encounters a specified text format. In either case, the textual data that is displayed is often presented to the user in a relatively primitive fashion based on default values assigned to a variety of display parameters; typically, the user has little or no control over the values of such display parameters as font size, reading area, and color.

Furthermore, the default values typically assigned to the display parameters are not necessarily calculated to improve readability or ease of reading by a user; that is, typical reader software fails to address the ergonomic considerations and needs of the user. For example, an 8 point font might be well-suited for a particularly quick user who wishes to scan a large amount of material in a short time; on the other hand, a user who reads more slowly and/or has impaired vision would likely desire a larger font size such as 12 or 14 point which would enable that user to more readily view and read the displayed text.

Another important ergonomic consideration regards the color of displayed text and the color of the background upon which it is displayed. Some colors and color combinations are better suited to displaying and reading text than are others. Further, some contrast between the text and background is required, otherwise the text could not be discerned. On the other hand, it is known that too much contrast is undesirable as well. Notwithstanding the importance of color and contrast in the readability of text on a display screen, most typical text readers and browsers fail to consider these issues.

Another shortcoming associated with currently available browsers and plug-in text readers is that they display text in such a way as to require the user to scroll up and down and across the display in order to view all of the text presented. Scrolling is, at best, inconvenient; further, moving text vertically and horizontally while reading is an unnatural way to view and read text, and is distracting to the user. Further, the typical user has a unique field of vision within which it is most efficient and convenient for that user to read; the unnatural reading process that results from scrolling requires the user to constantly change his field of vision and focus, and thus disrupts the reading process.

As a result of text readers and internet browsers' failure to address the ergonomic needs of users, users often suffer from physical conditions such as evestrain, headaches, and the like when compelled to read large amounts of text displayed by the typical w eb browser or plug-in reader.

The aforementioned problems become particularly acute when a user wishes to view and read a large amount of text, such as an entire book, on a computer display screen. For example, there are now a number of web sites devoted to making electronic versions of public domain books available for viewing. Many of the books available for on-line reading are quite lengthy and would be very inconvenient to read with the currently available browsers and plug-in readers. The same considerations also apply to electronic, or on-line, publishing wherein a publisher makes an electronic book or publication available for on-line viewing and reading. Clearly, readability of on-line text is an issue of paramount concern in instances where a user will be reading large amounts of text from a computer display screen; further, readability, or the lack thereof, will play a critical role in the long-term viability of online publishing.

A final problem, more typical of large text files, concerns the 'navigability' of the text file. That is, in a large text file that requires a great deal of scrolling or other manipulation, it is not uncommon for the user to get lost in the document. Further, because of the relatively primitive nature of the typical text file reader, a user cannot quickly and easily jump from one place in the document to another. Rather, the user must scroll through the document until the desired location is found; typical text readers make no provision for storing the addresses of desired locations for ready access at some future time.

Accordingly, what is needed is improved reader software for displaying text documents of a variety of formats on a computer display screen in a manner that closely simulates the display of text by a hardcopy book. Specifically, the reader software should be able to process a wide variety of text formats and/or should be able to convert a variety of text formats to a text format which is readily displayed by the reader software. Further, the reader software should be able to display at least one entire page of processed text completely within the viewable area of the computer display screen so as to preclude the need for scrolling. Also, the reader software should display text on a user computer screen in consonance with a set of display parameters such as reading area, font size, and background color; the values of at least some of the display parameters should be variable to suit the viewing and reading needs of particular users, and to suit the characteristics of a particular computer display screen. The reader software should further be capable of applying these display parameters to the display of text documents currently being displayed by internet browsers. Finally, the reader software should permit a user to readily jump from one location in the document to another location specified by the user, without scrolling or other manipulation of the display. SUMMARY OF THE INVENTION

The present invention has been developed in response to the current state of the art, and in particular, in response to these and other problems and needs that have not been fully or completely solved by currently available reader software. In summary, advantages and features are achieved with improved reader software for use in displaying text files on the display screen of a user computer.

Embodiments of the present invention are particularly suitable for use as a stand-alone program, and alternatively as a plug-in module for use in conjunction with an internet browser program. In a preferred embodiment, the reader software operates as a plug-in module in conjunction with an internet browser program. When the browser accesses a text file formatted for the reader software of the present invention, the browser initializes the reader software, which then accesses and displays the text file. Preferably, the browser points the reader software to a memory location wherein the text file is located; the reader software searches the memory location for a pre-defined text file format and, upon recognition of the pre-defined text file format, retrieves the text file for processing. Where necessary, the reader software converts the text file to a format, which the reader software can display. Preferably, the reader software uniformly distributes the text in the text file throughout a plurality of electronic pages. The reader software then formats each of the electronic pages so that each page can be displayed in its entirety on a user display screen, without the need for scrolling or other display manipulation; in a preferred embodiment, the display screen is a computer video screen. After formatting the electronic pages, the reader software then stores the electronic pages in a memory location for retrieval and display. Preferably, the reader software allows a user to view a plurality of books simultaneously. In a preferred embodiment, the text is distributed throughout the electronic pages in consonance with a plurality of display parameters, which include, but are not limited to, font size, background color, and reading area. Preferably, the background color is beige or the like, and the text is a dark color such as black, blue, gray, or the like. The reading area display parameter preferably comprises at least a variable height and width. In a preferred embodiment, the values of at least some of the display parameters are variable and are assigned by a user so as to accommodate both the viewing and reading needs of particular users, as well as the characteristics of a particular display screen. Further, in a preferred embodiment, the text is displayed on the screen much like the manner in which a book appears to a reader, i.e., two pages at a time. Additionally, in a preferred embodiment, the user can readily adjust at least some of the display parameters so as to display more than two pages at once. Preferably, the user can adjust at least some of the display parameters so that a relatively greater number of pages can be displayed on relatively larger display screens. That is, the user can desirably adjust the number of pages displayed in accordance with the size of the user's display.

Preferably, the reader software comprises decryption capability to decrypt encrypted text files when a user has satisfied specified conditions; in a preferred embodiment, the specified conditions include, but are not limited to, electronic payment, and password requirements. Further, in a preferred embodiment, the reader software also comprises usage types which define the uses that a particular user ma> make of a given text document; preferred usage types include, but are not limited to. copying, and printing the text document, wherein printing is limited to a predetermined number of copies or a pre-determined portion of the book. Usage types may also be used to restrict the use of the text document to a particular computer.

The reader software also preferably includes a file wherein a user can store links to desired locations in the text document; by selecting a link, the user can jump directly to that location without scrolling or other manipulation of the display.

These and other features, and advantages of the present invention will become more fully apparent from the following description and appended claims, or may be learned by the practice of the invention as set forth hereinafter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Reference will now be made to figures wherein like structures will be provided with like reference designations. It is to be understood that the drawings are diagrammatic and schematic representations of presently preferred embodiments of the invention, and are not to be construed as limiting the present invention.

In general, the present invention relates to reader software for use in processing and displaying text files on a user display. Figures l a through 5b indicate various presently preferred embodiments of reader software conforming to the teachings of the invention. Reference is first made to Figure la, which depicts reader software 100 and an internet browser 200; in a preferred embodiment, the reader software 100 operates as a plug-in in conjunction with the internet browser 200. Both the reader software 100 and the internet browser 200 are in communication with a computer 300. The computer 300, in turn, is in communication with the internet 400. The reader software 100 comprises a bookmark file 102, an access module

104, a text processing module 106, and a display parameter file 108 comprising a plurality of pre-defined display parameters 1 10 each having pre-defined values. The display parameters 1 10 include, but are not limited to, a reading area 112 having a variable height and width, and a font size 1 14; the reading area 1 12 defines a space in which text will be displayed for viewing by a user. Note that while this particular preferred embodiment comprises a display parameter file 108 of pre-defined display parameters 1 10 each having a pre-defined value, the present invention also contemplates reader software 100 having display parameters 1 10 whose values are user-variable. The use of display parameters, and particularly variable display parameters, is advantageous because the display parameters permit user-customized text display. Thus, in an alternative embodiment, the user has the option of displaying a number of pages in consonance with the size of the display in use, the larger the display, the more pages can be displayed at any one time. This feature is particularly advantageous where the display in use is 17 inches or larger. In an alternative embodiment, the reader software 100 automatically assigns a value to at least one of the pre-defined display parameters 1 10. In yet another alternative embodiment, the reader software 100 assigns a value to the reading area 1 12 based upon the characteristics of the particular display 302 to be used for displaying text. In addition to the display 302, the computer 300 comprises a processor 304. and at least a first memory location 306 and a second memory location 308; finally, the computer 300 further comprises a user input device 310 for receiving and transmitting input from a user 312. In an alternative embodiment, the display 302, the user input device 310, and the user 312 are in a location remote from the computer

300. An example of this alternative embodiment is an arrangement wherein a user/subscriber interacts with the internet via a keyboard in his home, information thus obtained is then displayed on the user's television set; the user has no computer however, the computer that processes input provided by the user is located remotely from the user.

With reference now to Figure lb, and with continuing reference to Figure la, in step 500, input from a user 312 via a user input device 310 directs the processor 304 to initialize the internet browser 200. After initialization of the internet browser 200, step 502 is entered wherein the internet browser 200 causes internet files, indicated generally as 402, to be downloaded from the internet 400 to the first memory location 306. The downloaded internet text files 402 may be subdivided into two categories: i) internet text files 404 having a format, or formats, that makes them compatible for display (hereinafter 'browser-compatible text file 404') within the internet browser 200; and, ii) internet text files 406 having a format, or formats, which makes them incompatible for display (hereinafter 'browser-incompatible text file

406') within the internet browser 200.

In step 504, the internet browser 200 examines the downloaded internet text files 402. If, after examination of the downloaded internet text files 402, the internet browser 200 detects browser-compatible text files 404, the internet browser enters step 506, causing the processor 304 to retrieve the browser-compatible text files 404 from the first memory location 306 and display the browser-compatible text files 404 on display 302.

In an alternative embodiment, the internet browser 200, upon detection of browser-compatible text files 404, may nevertheless initialize the reader software for display of the browser-compatible text files 404. With specific reference to Figure lc. steps 500 and 502 would be entered (as in Figure l b.), then the process would proceed directly to step 508 wherein the internet browser 200 causes the reader software to be initialized. Next, step 510 is entered wherein the internet browser 200 points the access module 104 to the first memory location 306. In step 513, the access module 104 causes the processor 304 to search the first memory location 306 for downloaded internet text files 402; with continuing reference to step 513, the processor 304 then retrieves the downloaded internet text files 402. The process then enters step 514 wherein the text processing module 106 causes the processor 304 to do the following: i) uniformly distribute text from downloaded internet text files 402 throughout a set 408 of electronic pages 410; ii) retrievably store the electronic pages 410 in the second memory location 308; iii) retrieve one or more electronic pages 410 from the second memory location 308; and iv) display the retrieved electronic pages 410 within the space defined by the reading area 1 12. After step 514 is complete, the process then enters steps 516, 518, and 520 as indicated in Figure l c. Steps 516, 518, and 520 of Figure lc. are identical to those steps in Figure l b.; thus, no further description of those steps is required or provided.

With continuing attention now to Figure l b., if, after examination of the downloaded internet text files 402, the internet browser 200 detects browser- incompatible text files 406, the internet browser 200 enters step 508. causing the reader software 100 to be initialized.

In step 510, the internet browser 200 points the access module 104 to the first memory location 306. In response to the direction from the internet browser 200. the access module 104 enters step 512 by accessing the browser-incompatible text files 406. Specifically, the access module 104 causes the processor 304 to search the first memory location 306 and retrieve any and all browser-incompatible text files 406 found therein. In a preferred embodiment, the reader software 100 is capable of displaying a plurality of pre-defined internet text file format types; in an alternative preferred embodiment, the reader software 100 causes the browser-incompatible text files 406 to be converted to a format compatible for display within the reader software 100.

After the browser-incompatible text files 406 have been accessed by the access module 104, step 514 is entered wherein the text processing module 106 causes the processor 304 to do the following: i) uniformly distribute text from the accessed browser-incompatible text files 406 throughout a set 408 of electronic pages 410. wherein the distribution of the text is consistent with the pre-defined display parameters 1 10; ii) retrievably store the electronic pages 410 in the second memory location 308; iii) retrieve one or more entire electronic pages 410 from the second memory location 308; iv) display on display 302 the retrieved electronic pages 410 entirely within the space defined by the reading area 1 12, i.e., the retrieved electronic page(s) 410 are displayed so that the entire page(s) can be viewed at once without scrolling or other display manipulation; v) clear a displayed electronic page 410 from the reading area 1 12; and vi) retrieve one or more electronic pages 410 from the second memory location 308, and display on display 302 the retrieved electronic page(s) 410 entirely within the reading area 112. When the electronic page(s) 410 are displayed thus, the need for scrolling or other display manipulation by the user is obviated. This feature, in combination with the variable display parameters previously discussed, makes this invention very flexible and particularly well-suited to display text in a manner that is sensitive to the unique ergonomic needs of a wide variety of computer users. Further, in an embodiment where at least some of the display parameters are adjustable by the user, the inherent flexibility of the present invention is further enhanced by the fact that the user can adjust the number of pages displayed in accordance with the size of the user's display. In particular, users with relatively large displays, e.g., 17 inches or larger, can display multiple pages at once, thus reducing the number of page turnings required in reading a given text. In a preferred embodiment, sub-parts (v) and (vi) of step 514 are performed in response to input from the user 312 via a user input device 310.

Also, in a preferred embodiment, the bookmark file 102 comprises a plurality of links 105 wherein selection of a particular link 105 by a user 312 will cause the reader software 100 to enter step 516 wherein the reader software 100 displays an electronic page 410 associated with the selected link 105; the links 105 are specified by a user 312 and can be added or deleted to/from the bookmark file 102 at the discretion of the user 312.

In a preferred embodiment, performance of sub-parts (v) and (vi) of step 514 is visually indicated on the display by means of a visual indication process which causes text contained in an electronic page 410 to appear on, and/or disappear from, the display 302, in a gradual manner. Preferably, the visual indication process comprises at least 'fade in' and 'fade out' steps. Specifically, the text of the electronic page 410 being cleared fades out from the display 302, and then the text from the new electronic page 410 to be displayed fades in to the display 302: preferably, the visual indication process occurs in a measured subfraction of a second.

The fade out and fade in steps may be accomplished in any number of ways, including, but not limited to, gradually shrinking the displayed text to a predetermined size and then displaying, in a predetermined size, the text of a new electronic page 410 and then gradually increasing the size of the newly displayed text to a size consonant with the display parameters 1 10. In an alternative embodiment, performance of sub-part (v) of step 514 is preferably visually indicated on display 302 by an image of a turning page or the like. In yet another alternative embodiment, performance of sub-part (v) of step 514 is visually indicated on display 302 by an image of a turning page or the like, either alone, or in combination with the gradual manner previously described.

Reference is next made to Figure 2a which depicts reader software 100A comprising an access module 104A, a text processing module 106A, and a display parameter file 108 comprising a plurality of pre-defined display parameters 1 10, the display parameters 1 10 including a reading area 1 12 having a variable height and width, and a font size 1 14; in an alternative embodiment the display parameters 1 10 include background color, wherein the background color is beige or the like. Further, in an alternative embodiment, the font size is 8 point or the equivalent. In a preferred embodiment, the reader software 100A further comprises a user input device 310 for facilitating communication between a user 312 and the processor 304. In an alternative embodiment, the reader software 100A further comprises a decryption key 600 to decrypt encrypted, downloaded internet text files 602 prior to processing of those files by the text processing module 106A.

With continuing reference to Figure 2a, the access module 104A is in communication with the processor 304. The processor 304, in turn, is in communication with a first memory location 306 and with a second memory location 308; the processor 304 is also in communication with a video display 302.

With reference now to Figure 2b, and with continuing reference to Figure 2a, in step 700 the access module 104A accesses a downloaded internet text file 402 stored in the first memory location 306. Preferably, the access module 104A performs step 700 by causing the processor 304 to do at least the following: i) search the first memory location 306; ii) identify downloaded internet text files 402 found in the first memory location 306; and iii) retrieve one or more of the downloaded internet text files 402 from the first memory location 306. In an alternative preferred embodiment, the access module 104A accesses a downloaded internet text file 402 stored in the first memory location 306 in response to direction passed to the access module 104A by a user 312 via the user interface device 310 and the processor 304.

After a downloaded internet text file 402 has been accessed by the access module 104A, the text processing module 106A performs step 702 by causing the processor 304 to do the following: i) uniformly distribute text from the internet text file throughout a set 408 of electronic pages 410, wherein the distribution, as previously noted, is consistent with the dictates of the display parameters 1 10; and, ii) retrievably store the electronic pages 410 in the second memory location 308.

In an alternative embodiment, the text processing module causes the processor 304 to perform the following additional tasks: a) retrieve one or more entire electronic pages 410 from the second memory location 308; b) display on display 302 the retrieved electronic pages 410 entirely within the space defined by the reading area 1 12, i.e., the retrieved electronic page(s) 410 are displayed so that the entire page(s) can be viewed at once without scrolling or other display manipulation; c) clear a displayed electronic page 410 from the reading area 1 1 2; and d) retrieve one or more electronic pages 410 from the second memory location 308 and display on display 302 the retrieved electronic page(s) 410 entirely within the space defined by the reading area 1 12. Further, sub-parts (a) through (d) are performed in response to input from the user 312 via a user input device 310; further, performance of sub-part (c) of step 702 is preferably visually indicated on display 302 by an image of a turning page or the like. Additionally, when two electronic pages 410 are simultaneously displayed, the electronic pages 410 are displayed as a left page and a right page, so as to mimic a hard copy book.

In an alternative embodiment, additional step 701 is performed wherein the text processing module 106A causes the processor 304 to convert the downloaded internet text file 402 to a pre-defined format prior to uniformly distributing the text from the downloaded internet next file 402 throughout a set 408 of electronic pages 410.

Reference is next made to Figure 3a which depicts an electronic data package 800 comprising textual data 802, a display parameter file 108 comprising a plurality of pre-defined display parameters 1 10. each pre-defined display parameter 1 10 having a pre-defined value, and reader software 100B. In an alternative embodiment, the electronic data package 800 also includes pre-defined usage types 804, wherein the pre-defined usage types 804 include electronic copying of the textual data 802, printing a pre-determined number of copies of the textual data 802, and viewing of the textual data 802 on a specified display. In another alternative embodiment, said predefined usage types comprise self-executing programmable code. Pre-defined usage types are a valuable feature of the invention because they allow the vendor 806 a significant measure of control over copyrighted works. With continuing reference to Figure 3a, the reader software 100B is in communication with a processor 304; the processor 304. in turn, is in communication with a display 302 and a memory location 306A.

With reference now to Figure 4b, and with continuing reference to Figure 4a, a flow diagram is depicted showing the steps of the method 1000 for selling books 1 100 in electronic format. Specifically, in step 1002 an inventory 1 102 of books 1 100 in electronic format is maintained. In step 1004 of the method 1000, a customer 312A is allowed to select at least one of the books 1 100 in electronic format. In step 1006 the customer 312A must satisfy pre-defined access criteria 1 108 in order to advance to step 1010 wherein the customer 312A is permitted to retrieve the selected book 1 1 10. In a preferred embodiment, the pre-defined access criteria 1 108 comprise, but are not limited to, electronic payment, entry of a pre-determined password, consent to use conditions, consent to licensing agreements, or the like; the present invention also contemplates combinations of these criteria. If the customer 312A fails to satisfy the pre-defined access criteria 1 108. the method 1000 for selling books 1 100 in electronic format enters step 1008 wherein access to the selected book 1 1 10 is denied. Upon satisfaction by the customer 312A of the pre-defined access criteria

1 108, and retrieval of the selected book 1 1 10, the method 1000 for selling books 1 100 in electronic format enters step 1012 wherein the reader software 100C allows the customer 312A to view the selected book 1 1 10 by causing processor 304 to do the following: i) read the textual data from the selected book 1 1 10; ii) assign values to the pre-defined display parameters 1 10, wherein the pre-defined display parameters

1 10 include reading area 1 12, and font size 1 14 - note that this invention also contemplates the use of display parameters 1 10 such as font type, and background color, in combination with reading area 1 12 and font size 1 14, the background color being preferably beige or the like; iii) uniformly distribute text from the selected book

In a preferred embodiment, the customer 312A selects which electronic page 410 or pages will be displayed and/or cleared from the display 302.

After step 1012, the method enters step 1014 wherein the customer 312A is permitted to use the selected book 1 1 10 in accordance with pre-defined usage types 804; in a preferred embodiment, the pre-defined usage types 804 include copying and printing the selected book 1 1 10. Note that the invention also contemplates usage types such as forwarding, or sending, the selected book 1 100 by electronic mail.

In an alternative embodiment, the method 1000 of selling books 1 100 in electronic format comprises the further step 1016 of encrypting the selected book 1 1 10 prior to storage in the inventory 1 102; an additional step 1018 is performed when the reader software 100C decrypts the selected book 1 1 10 upon satisfaction by the customer 312A of pre-defined access criteria 1 108. Alternatively, step 1018 is entered when the customer 312A decrypts the selected book 11 10 using a decryption key 602B provided to the customer 312A by the vendor 806 upon satisfaction by the customer 312A of the pre-defined access criteria 1 108. This feature is particularly valuable in protecting the vendor 806 from unauthorized use of the selected book 1 1 10. Without this feature, electronic publishing of copyrighted material would not be practical; any user could copy and/or sell the books 1 100 at will, thus denying the vendor profits from the sales of the books. In an alternative embodiment, the method 1000 of publishing books 1 100 in electronic format further comprises step 1020 wherein a customer 312A is allowed limited access to a pre-defined portion 1 1 12 of the selected book 1 100 in electronic format, and step 1022 wherein the customer 312A uses the reader software 100C to display only, on the video display 302, the pre-defined portion 1 1 12 of the selected book 1 1 10. More specifically, in step 1022, the reader software 100C causes the processor 304 to do the following: i) read the textual data associated with the predefined portion 1 1 12 of the selected book 1 1 10; ii) assign values to the pre-defined display parameters 1 10, wherein the pre-defined display parameters 1 10 include reading area, and font size - in an alternative embodiment, the set 108 of pre-defined display parameters 100 includes background color, the background color being beige or the like; iii) uniformly distribute text from the pre-defined portion 1 1 12 of the selected book 1 1 10 into at least one electronic page 410, in a manner consistent with the pre-defined display parameters 1 10; and, iv) display on display 302 the electronic page 410 entirely within the space defined by the reading area 112. This feature of the invention thus permits a potential customer to preview a portion of an electronic book prior to committing to purchase the book; this feature is particularly useful where a potential customer is unfamiliar with a particular book.
