  • Users of mobile devices and people with disabilities experience similar barriers when interacting with Web content. For example, mobile phone users will have a hard time if a Web site's navigation requires the use of a mouse because they typically only have an alphanumeric keypad. Similarly, desktop computer users with a motor disability will have a hard time using a Web site if they can't use a mouse.

  • Some tips from the article include:Fieldset and Legend tags must be used together, never independently of each other.Keep the content of the Legend tag brief (the Legend may be read when each of the controls contained in a Fieldset receive focus.)In Windows Eyes, the option to read the Legend tag is off by default.Fieldsets may be nested.

  • The RNIB report finds people over 55 are three times more likely to have seeing difficulties as those in the 16-24 age bracket, which is a greater increase with age than with other kinds of disabilities.
  • In addition, the report finds that people who are disabled with seeingdifficulties are less likely to be employed (48 per cent) than those with other kinds of disability (50 per cent); this compares to an overall employment rate of 75 per cent among people of working age. For people with more than one disability, the employment rate drops to 38 per cent, however for people with ’seeing difficulties’ that do not constitute a disability the rate is much higher at 83 per cent. The unemployment rates are 8 per cent for disabled people as a whole but 13 per cent for those disabled by visual impairment. In contrast, the report also found that a higher than average proportion of visually impaired disabled people are employed in high-level positions.

  • “Ensure that foreground and background color combinations provide sufficient contrast when viewed by someone having color deficits or when viewed on a black and white screen.”
  • Scoptic Sensitivity Syndrome
  • can make high contrast text difficult to read because the words seem to constantly move on the page.

  • anecdotal evidence suggests that, as soon as you reduce the colour contrast, the reading difficulties suffered by dyslexics are alleviated, to some degree, across the board.
  • Contrasts that comply with the thresholds can, and do, create very real problems for dyslexics.
  • t has been my experience that just about every issue within accessible web design is about balance. Skew any one factor too much in favour of a particular user group and you risk disadvantaging another group with opposing needs.
  • What I am suggesting is that, if a colour theme is chosen that conforms to, or exceeds, the W3C colour difference threshold, an alternative, low contrast style sheet should be provided as standard.
  • I then suggested that “disability” be defined as an “inability to pursue an activity because of a medically determinable physical or mental impairment.”
  • suggest that adhering to the Hewlett-Packard colour difference threshold would represent a more balanced approach to the issue of colour contrast. To that end,
  • I’ve developed an alternative color contrast analyser for people to try.

  • The specific needs of dyslexics tend to be overshadowed by the more widely understood needs of the visually impaired. Unfortunately, design decisions that benefit the latter group tend create problems for the former. This is never more evident than in so-called “accessible” text only pages with their emphasis on high contrast and complete lack of images and colour.
  • What is Dyslexia?
  • The word “dyslexia” can be broken down into two parts: “Dys” meaning poor and “lexia” meaning language. Thus dyslexics have difficulties with words. Current theories suggest that

  • it is not a visual problem but a word decoding, or recognition deficit.
  • Our ability to recognise words is thought to be based upon two slightly different “memory skills” — phonetic memory and lexical memory. Dyslexics may have a good phonetic memory — as evidenced by their tendency to spell many words phonetically — but a very poor lexical memory.
  • No two dyslexics demonstrate their disorder in the same manner. It can affect boys and girls equally, across all socioeconomic classes worldwide.
  • “A combination of abilities and difficulties that affect the learning process in one or more of reading, spelling and writing.
  • Accompanying weaknesses may be identified in areas of speed of processing, short-term memory, sequencing and organisation, auditory and/or visual perception, spoken language and motor skills. It is particularly related to mastering and using written language, which may include alphabetic, numeric and musical notation.”
  • the more complex the written language is, the greater the likely percentage of people who will have difficulty reading it.
  • As many as 1 in 10 people in the UK are dyslexic.
  • Worldwide, it is likely that the number of dyslexics is likely to be equal to, if not significantly larger than, the number of visually impaired people.
  • poor short-term memory and organisational skills will mean that site navigation and page organisation become more important.
  • high contrast text difficult or impossible to read. The phrases I’ve heard most often are “the text keeps moving” or “the words seem to dance on the page.”
