Definitions

  • the present invention concerns improving the readability of text, an improved text product, and a computer system and method for creating such a text product. More particularly, but not exclusively, this invention concerns computer software for converting a source text into a new text product (for example in the form of a data file) which may improve readability of the text for certain readers.
  • the invention also concerns a novel formatted text product, a method of converting text comprising a multiplicity of sentences into a formatted text data product, a computer system for converting a source text comprising a multiplicity of sentences into a formatted text data product, a computer software product for programming a computer to create such a computer system, and a method of improving the ease of reading a literary work.
  • US 3,61 1,593 provides a proposal for improving readability of a text by means of providing indications in the margins of the text at the start of each line, or every other line, to guide the reader's eye from one line to the next.
  • indications such as bullet points or other marks
  • the appearance of such special extra markings in the text may make readers suffering from reading difficulties feel patronised or otherwise made to feel different from more able readers.
  • the solution offered by US 3,611,593 is thus rather intrusive.
  • the present invention seeks to mitigate the above-mentioned problems.
  • the present invention seeks to provide a text product which may ease reading of the text by certain readers.
  • the present invention seeks to provide a method and/or apparatus and/or software which enable the creation of such an improved text product.
  • the present invention provides, according to a first aspect, a formatted text product comprising text formatted so that the majority of pairs of adjacent lines of text have been modified such that one of the last word or words of the first line of a pair of adjacent lines is repeated as the first word or words of the second line of the pair of adjacent lines.
  • the present invention is designed to help readers with tracking when the eye moves to locate the following line. This is achieved by means of the pairs of repeated word or words from the end of one line to the beginning of the next which effectively add a link or connection between adjacent lines. It is believed that the repetition of a word at the end of a line at the beginning of the next will assist certain readers in tracking from one line to the next.
  • it is reckoned to be a sufficiently 'soft ' solution that its application will not bother fluent readers, since the brain rapidly ceases to notice any difference between conventional text and this 'connected' text.
  • the formatted text product may be in the form of printed matter, such as a paper- based publication, for example a book.
  • the formatted text product may be an electronic data product, for example a data file.
  • the text product may be displayed on a portable electronic book reader, such as for example the KindleTM device sold by Amazon.
  • the text product may be displayed within a web-page, for example within or overlaying a browser window on the display device of a computer system.
  • the electronic data product could be stored on physical media, such as the memory of a computer, a hard drive, memory stick or other memory device, or a data disc (such as a CD-ROM, DVD or the like).
  • the text product may be displayed on an electronic display device, for example associated with a computer.
  • the computer may be a tablet computer, smart phone, desk- based PC, laptop, or similar computing apparatus.
  • the text product may be displayed in a distinct part of the display separate from the source text which may also be displayed, optionally at the same time, on the same, on the same device.
  • the text product may be displayed so that it overlays, partially or wholly, or otherwise masks or hides (at least partially), the display of the source text.
  • the text product may be displayed in a window, pop-up, or similar.
  • Such a window, pop-up, or similar object may have the appearance, to the user, of a lens which transform the source text via the lens into the formatted text product.
  • the formatted text product may be such that substantially all pairs of adjacent lines within a paragraph of text have been modified such that one of the last word or words of the first line of a pair of adjacent lines is repeated as the first word or words of the second line of the pair of adjacent lines.

  • the method may include outputting the formatted text data product so created, for example by displaying the text on a display screen, by printing the text, and/or by saving the text for subsequent use.
  • the step of outputting of the formatted text data product may be in the form of outputting a data file, for example in the form of an electronic data product.
  • the method may include providing a source text to be converted, the source text comprising a series of words.
  • the method may include identifying words in a source text, and in particular, identifying the last word or words in a line.
  • each of the "words" so identified when performing the step of identifying the words may consist of a series of characters, for example including punctuation, and not necessarily being in the form of words that would normally be found in a conventional dictionary.
  • a "word” may simply be defined as the series of characters between a space and the end of a line or the next space. There may therefore be no analysis of the word so identified, and the step of identifying a word may for example simply comprise detecting the start and end of a word, without requiring knowledge of the content of the word so "identified".

  • a line which includes formatting of a certain type may be identified as not being a line of words (or being a line of words but not one that is to be processed so as to produce connected text - such as a repeated word in an adjacent line).
  • the one or more lines of text so identified may be stored as data in a different way such that the data includes additional line information allowing a different means for subsequently identifying separate lines in the text.
  • the step of identifying lines of words in a text may include dividing a string of words, for example without any information concerning line width, into a set of lines of words. Dividing a string of words into a set of lines of words may include using page width information and character spacing information.
  • the method may include creating as part of the formatted text data product a first line of words, in dependence on the available line width of a display area, by populating the line with a first sequence of words forming part of the series of words from the source text.
  • the method may include a step of inserting, at the start of a line of words in the formatted text data product, a copy of the last word or words of the preceding line of words. Such a step may be repeated a multiplicity of times.

  • One or more software modules may be provided to carry out steps of the method.
  • the method may comprise inputting into the memory of the computer, data representing the source text to be converted.
  • the computer may for example use one or more software modules to perform the following sub-steps:
  • the method may include (as step (e) for example) repeating step (c) but in respect of the second line of words, and repeating step (d) to create a third line of words after the second line of words.
  • the steps (a) to (d) are preferably carried out in that order.
  • the source text when provided as a text data product, may be converted into the formatted text data product (for example so that after the method is performed the source text so provided only survives as the resultant formatted text data product).
  • the source text may thus be progressively edited/changed during performance of the method.
  • the formatted text data product may be separate from the data representing the source text.
  • the step of populating the line with a first sequence of words forming part of the series of words from the source text may simply be performed by manipulating the source text.

  • a function is provided by a software module of the host software application.
  • Such a function may be useful when the method creates a copy of the source text, and then manipulates that copy of the source text to produce the formatted text data product, (or when the method simply works by directly manipulating the source text to produce the formatted text data product), rather than creating a new formatted text data product line by line from the source text.

  • the connected text is displayed/printed in landscape, not portrait, in Figure 2.
  • Certain embodiments of the invention have particular application to a text printed in landscape, which would normally present difficulties with tracking, as the eye of the reader has further to travel (laterally) to the next line, and the reader is more prone to losing his/her place in the text.
  • An advantage of landscape display /printing, which embodiments of this invention would render more practicable, is that there is less tracking to do, since there are fewer line breaks in a text, by virtue of the text being broader.

  • the system that is used to convert a source text into a connected text has access to a dictionary of such compound word elements, so as to ascertain whether the last two or three words on a line belong to a compound-word-element.
  • the system may also ensure that a compound-word-element is not split across two lines in the connected text, if there is insufficient room at the end of the line for the compound-word-element, by pushing the compound-word-element and the preceding word onto the second of the two lines and repeating said preceding word at the end of the first line.

  • the repeated word 94 can be displayed in such a way that its isolation from the primary text 92 is clear. In Figure 3b, this is achieved by indenting the primary text 92 with a sufficiently large margin so as to accommodate most if not all of the repeated words 94 in the left hand margin and leave a gap between the repeated word 94 and the following text on the same line.

  • the macro is designed to produce a new document with the same formatting as the source document but converting the text into a connected text format.
  • First (step 10) the macro copies the source document and creates a new file.
  • the macro then performs the same loop of steps in respect of each successive line of text on screen. A check is performed to ensure that the line does not represent the end of the paragraph. This is performed by checking whether the last character (including non-printing characters and characters otherwise not visible to the user) on the line is a carriage return or a new paragraph mark. If the line in question is at the end of a paragraph then the macro proceeds to the next paragraph in the document, or of there are no further paragraphs, the macro ends (box 12).
  • the text unit at the end of the line is selected (box 14), using the corresponding commands in MS Word (in the same way as if a user with the cursor on the line in question presses the "END" key and then simultaneously presses "SHIFT", "CTRL” and "LEFT ARROW”).
  • the text unit selected will be a word, whereas in other cases it will not.
  • the character or characters selected may be one or more punctuation marks.
  • the macro checks whether the text unit is not a word unit and if so, then additionally selects the word unit immediately preceding the text unit (box 16) and intervening space characters. For example, if the two words and comma at the start of this sentence were the last two words on a line, the macro would initially select a single-character text unit consisting of the comma, and the macro would then additionally select the word
  • the text that is selected (with or without punctuation) is then copied and used to create a text insert string.
  • the text insert string is created (box 20) by adding a number of normal spaces (i.e. not non -breaking spaces) before the copied text equal to the free space at the end of the line.
  • the text insert string is then added at the end of the line (box 22).
  • the spaces effectively fill the space at the end of the line, ensuring that the first word on the next line (including punctuation, if any is present) is the same as last word on the line before.
  • MS Word then adjusts subsequent lines automatically to ensure that each line of text does not exceed the available width, thus shifting words at the end of one line to the beginning of the next, as appropriate.

  • the browser in this embodiment is Microsoft's Internet ExplorerTM, but the principles of operation apply equally to other commonly used browsers, such as for example Mozilla's FireFoxTM or Google's ChromeTM browsers.
  • Such browsers are provided with rendering engines that facilitate the arrangement and display of text in a given window-size. If the window is resized, the rendering engine is able to re-display the text appropriately.
  • the plug-in uses html tags to process text to be displayed on screen. Tags are used in html to identify different elements of text, for example to display / format the tagged text in a certain way. Example text-formatting tags and their meanings are set out below: ⁇ B> ⁇ /B> Bold text
  • the plug-in processes the paragraphs one-by-one.
  • the start of a paragraph is denoted by the ⁇ p> tag and the end with a ⁇ /p> tag.
  • the plug-in starts (box 30) by converting the text within a paragraph into separately tagged words.
  • Each word is tagged with a ⁇ SPAN> tag, the ⁇ SPAN> tag being associated with a single identifier in the form of the string "ConnText" so that if text has already been processed by the plug-in it will not be inadvertently processed a second time.
  • Tagging each word in this manner also makes use of the browser's inherent features that enable the relative position of a tagged element on-screen to be determined.
  • the browser effectively automatically calculates a vertical offset parameter for each tagged element, the vertical offset parameter providing information concerning the relative positions vertically down the page/window of the text being displayed on-screen.
  • the plug-in compares successive pairs of tagged words (a step represented by box 34) until either the end of the paragraph is reached, which is signified by the tag ⁇ /P>, or the vertical offset parameters for the pair of tagged words are different, thus indicating that the second word of the pair is on the line of text immediately after the first word of the pair (decision path 36). If the second word of a pair is on a new line, then (box 38) a manual line break ⁇ BR> is inserted after the first word of the pair and a copy of the first word (with the ⁇ SPAN> tag) is inserted after the line break and before the second word, so that the first word on the new line repeats the last word on the previous line.
  • the rendering engine recalculates the positions of the remaining text (shifting along and moving words that spill over onto new lines, as appropriate).
  • the vertical offset parameters associated with any words that are pushed onto the next line down are updated as appropriate.
  • the plug-in processes the next line of text, adds another duplicate word, then the rendering engine adjusts the subsequent text, and so on.
  • the plug-in can be of a size that is much less than might otherwise be the case, resulting in a relatively small file-size for the plug-in.
  • FIGS. 6a to 7b show how html text is processed and displayed by means of the plug-in of the fourth embodiment.
  • Figure 6a shows some source html text
  • Figure 6b shows how this text is displayed in a window of the browser. It will be seen that the html text of Figure 6b, includes paragraph tags, ⁇ p> and ⁇ /p> and some text formatting tags.
  • the text formatting tags in this example are underlining of the words "Dyslexia and reading” by means of ⁇ u> and ⁇ /u> tags, emphasising with bold font the text "10% and 15%” with the ⁇ b> and ⁇ b> tags, and italicising the string " 'tracking' " with the ⁇ i> and ⁇ /i> tags.
  • the format style- 'display: block is sometimes used in websites to denote captions or "asides" within a body of text and other content.
  • the duplicated word in this embodiment is provided within the main body of text, and is not positioned within the left-hand margin or otherwise emphasised as being a special duplicated word within the text.
  • Figure 8 shows, according to a fifth embodiment, a flow chart of a computer program, for converting a source text into a connected text format.
  • the program copies the content, including source text, from the source document and creates a new file into which the source text is inserted (with other content being associated with the text as appropriate).
  • the new file is structured so as to be formatted in a series of lines of text in dependence on character font size, character spacing and display width settings. Each line has a fixed length and is typically populated by one or more works from the source text.
  • the program performs the same loop of steps in respect of each successive line of text in the new document. If the line in question is at the end of a paragraph then the program proceeds to the next paragraph in the document, or of there are no further paragraphs, the program ends (box 112).
  • the program moves to the first (or next) valid line of text (box 1 14).
  • the program checks whether the text unit at the end of the line is punctuation (or otherwise not a word), and if so, copies the word unit immediately preceding the non-word text (box 1 16) up to and including the text at the end of the line. Otherwise, the program copies the text unit (the word) at the end of the line (box 118).
  • a line return (“ ⁇ LR>") is then inserted at the end of the line (box 120) and the copied text unit (comprising the last word on the preceding line) is inserted at the beginning of the next line (box 122).

  • the repeated words could be displayed in a different font / colour.
  • the embodiments could be applied to non-English text and could be applicable to foreign language text.
  • the direction of reading may be from right to left.
  • the last word of text on a line may therefore be the leftmost word, and therefore the duplication of that last word on the next line would therefore appear on the right-hand side of the page.
  • the words left and right can be deemed as swapped over when the invention is applied in the context of a language that is written from right to left.
  • the terms "left” and "right” may be replace by "top” and "bottom” as appropriate.

  • Source text may be converted into a formatted text product with repeated words, by cutting and pasting (electronically for example) words one at a time into a new document or file. Once a line is populated with words and the next word to be added will cause a new line to be required, a line return may be inserted at the end of the line, and the last word on the line copied and pasted as the first word on the next line. The new document may thus be populated line by line, word by word, in this manner.
