Definitions

  • the presented invention related to improved computer output usability and enhanced readability via inclusive design principles.
  • the invention will achieve this without modification of the page boundaries, and therefore will not visually distort the content.
  • this is a method of adapting a page in a mark-up language to alter how it is displayed having the steps of identifying at least one boundary of an area of content within the page converting the display characteristics of the content, substantially retaining the identified boundaries.
  • the image or text is therefore not distorted and the method of modification is more efficient in comparison with prior art.
  • the client-side implementation is advantageous by facilitating closer coupling between display device and computer processing hardware.
  • the method allows improved alteration of the display page and removes the need to communicate preferences. This has advantages in terms of less telecom bandwidth / latency and more privacy. 2 Brief description of the Drawings:
  • Figure 1 illustrates examples of the various aIDEAS Personal Visual Adaptation of WWW systems.
  • Figure 2 is a schematic representation of a computer system.
  • Figure 3 is a flow diagram representing the aIDEAS Personal Visual Adaptation of WWW method
  • Figure 4 is a schematic representation of an application of an aIDEAS Personal Visual Adaptation of WWW Document Object Model method, according to the present invention.
  • Figure 5 is a schematic representation of an application of aIDEAS Personal Visual Adaptation of WWW Proxy method, according to the present invention.
  • Figure 6 is a schematic representation of an application of aIDEAS Personal Visual Adaptation of WWW Modified Browser method, according to the present invention.
  • aIDEAS Personal Visual Adaptation of WWW is a method of processing pages for display having the steps of identifying at least one boundary of an area of text within a page, the text being stored in the form of character codes, converting the markup language to convert the display characteristics of the text, substantially respecting the identified boundaries.
  • This modification may include font sizes, line spacing, letter spacing, font colour and typeface.
  • a page may also be an image which can be modified to match client preferences.
  • This method therefore allows for personal optimisation via user-definable parameters to set the display characteristic converting steps.
  • substantially retaining is intended to distinguish from zoom viewers, which inherently distort the boundaries and cause the zoomed text to obscure other parts of the display (203) on which the page content is shown.
  • the proxy method requires use of a proxy server in-between the computer system and the target web server.
  • a Proxy server is therefore defined as a computer program which offers a computer network service to allow clients to make indirect network connections to other network services.
  • the proxy server provides the page either via the specified server, or by serving it from a cache.
  • Popular proxy servers include the Squid cache (HTTP for UNIX/Linux), the HTTP-Tunnel (Windows client), Wingate, Proxomitron, PHProxy and SJSWebProxy.
  • text is intended to encompass any letters, numerical characters and symbols of any kind of alphabet.
  • text is data consisting of a sequence of characters, as opposed to binary numbers, images, graphics commands, executable programs etc. It can be readily used on the majority of computers, although character set differences may require slight conversions.
  • Programming languages are defined as artificial languages that can construct computer programs in order to perform computation and / or organise the flow of data between mechanical devices. Languages are classified by the computations they can express and may contain constructs for defining and manipulating data structures or for controlling the flow of execution. Common examples include Java, Visual Basic, C, C++, SQL, while informal term usage includes mark-up languages, e.g. HTML and formal grammars, e.g. BNF.
  • HyperText Markup Language is the authoring language used to create documents within the WWW and defines the structure and layout of the Web document via tags and attributes. Page information is therefore stored within these multiple tags, and in addition these tags specify hypertext links.
  • HTML is an application of ISO Standard 8879:1986 Information Processing Text and Office Systems, Standard General Markup Language (SGML). HTML can therefore be classed as a presentation language rather than strict programming language.
  • Extensible Markup Language is a simple, very flexible text format derived from SGML (ISO 8879).
  • Javascript is defined as an interpreted programming or script language - in essence a system of programming codes, created by Netscape, which can be embedded into the HTML of a web page to add functionality.
  • page is intended to encompass web-pages, frames of a film, pages of a presentation, single images, sequence of images, frames of a video stream and frames of a film. All Web sites are a collection of electronic "pages.”
  • Each Web page is a document formatted in HTML (Hypertext Mark-up Language) that can contain text, images, on-line elements or media objects such as RealAudio Player files, QuickTime videos or Java applets.
  • the accompanying elements may be in the format of files such as, GIF, JPG and CSS and each site page has a unique URL, and identifying Name. Pages can be static or dynamically generated. It may be a stand-alone HTML document, or one which is contained within a frame: all frames and frame parent documents are counted as pages.

  • the term Document Object Model describes the tree structure of an HTML document.

  • the WWW is a system of Internet servers, linked by common protocols, which support specially formatted documents in HTML (HyperText Markup Language). Links are supported to other documents, as well as graphics, audio, and video files. It is also known as W3, the Web and the World Wide Web. However, the WWW can be further defined as the resources that can be accessed using Gopher, FTP, HTTP, telnet, USENET, WAIS and some other tools.

Abstract

L'adaptation visuelle personnelle (PVAW) aIDEAS est un procédé d'adaptation d'une page Internet dans un langage balisé pour modifier la façon dont elle est affichée, par exemple, une modification de la police, de la couleur ou de la dimension du texte. Ceci est conditionné par l'identification d'au moins une limite d'une zone de contenu dans la page et par la conversion des caractéristiques d'affichage du contenu, tout en retenant sensiblement les limites identifiées. Par conséquent, le contenu n'est pas déformé et PVAW est plus efficace par comparaison avec des outils de zoom. Ce procédé repose sur un choix personnel et de plus la mise en oevre du côté client permet un couplage plus proche entre un dispositif d'affichage et un matériel de traitement informatique et élimine le besoin de communiquer des préférences. Ceci a des avantages en termes de diminution de la bande passante/latence de télécommunication et d'augmentation de la confidentialité.
