  • And that leads me to three great videos posted on the Yahoo! User Interface Blog: In Introduction to Screen Readers, Yahoo! engineer Victor Tsaran talks about who will be likely to use a screen reader, how screen readers work, and how they can be used to interact with the computer desktop and to browse web sites. In Introduction to Screen Magnifiers, Karo Caran shows how the screen magnifier ZoomText is used to make the computer desktop and web sites readable to people with reduced vision. And finally, in From the Mouth of a Screenreader, Doug Geoffray from GW Micro (Window-Eyes vendor) talks about the history of screen reading software and how they analyse what is displayed on the screen in order to speak it to the user.

accessibility CSS Ordering link states

shared by Sandra Earl on 12 Oct 10 - Cached
  • Common knowledge to most who have been working with CSS for a few years, but perhaps not something that relative newcomers have come across yet: the order in which you define the different link states affects the end result. I prefer the following order: :link, :visited, :hover, :focus, :active.

  • Shorter line lengths and narrower text columns make reading easier.
  • Consider setting a percentage width for text areas and set the margins to “0 auto” via CSS. The page side margins will then increase proportionately on wider screens.
  • Most browsers have a default line-height of around 1em. This normally results in closely packed lines of text. Increasing the line-height to around 1.3em immediately makes longer lines of text easier to read. Likewise, ensure that paragraphs are visibly separated. Don’t be afraid of white space. Use it to enhance readability.

  • percentages or ems.
  • If possible, use a sans-serif font. The decorative “hooks” on the main strokes of serif letters may create additional problems for dyslexic users.
  • If you have to use a corporate serif font, consider reducing the letter-spacing slightly so that the letters within a word lie closer together but increasing the word-spacing to create a slightly larger distance between individual words.
  • uneven word spacing disrupts that pattern recognition.
  • Unjustified text, although less attractive at first glance. is far easier to read.
  • When italic fonts are used on a web page, the individual letters can have a slightly jagged line compared to a non-italic font. This “pixelation,” coupled with their “lean to the left” makes them hard for a dyslexic person to read. The effect is compounded if the text is also small.
  • Use italics sparingly and consider bold text for important words. They’ll be far easier to read.
  • Photographs, charts and icons can convey a great deal of information regarding the topic of a page. Graphics can break the page up into smaller chunks. They can also provide visual memory aids and support comprehension for dyslexics.
  • Dyslexics often have poor organisational skills. Lists can help them by organising information into small, logical chunks.
  • Dyslexics tend to have poor information processing skills. So it is relatively easy to overload them by literally providing too much information on one page.
  • Within a page, use headings to sub-divide the page logically and visually. Adding coloured heading backgrounds or borders will act as further support.
  • Consider breaking complex pages down into two or three smaller pages.
  • Keep site navigation simple and logical. Make sure that the Home page is easily reachable from any part of the site. Try not to “hide” this important link in a logo.
  • break long sentences down into two or more shorter sentences
  • Many designers do not realise that some screen reader users can see perfectly well. It is not uncommon for dyslexics to use screen readers to support their reading. This may create problems where text has been positioned off screen.
  • If you do make use of off screen positioning, try to do so sympathetically. Consider the viewpoint of those who can both hear the screen reader and see the page. Ask yourself if you’re potentially creating confusion.

accessibility HTML5 lists development standards

shared by Sandra Earl on 12 Oct 10 - Cached
  • One of the things that have long irritated me about HTML is the restriction on what elements are allowed inside lists. The specs for both HTML 4 and 5 allow only li for ul, ol, and only dt and dd are allowed inside dl definition lists. I’d like to expand that to allow h1…h6, section and div.
