- Measuring accessibility
- By Roger Hudson, DingoAccess Random thoughts, stories and ideas from Roger Hudson of Web Usability, 2 November 2011. "There has been much discussion, and some arguments, about how to determine the accessibility of websites. Unfortunately, this is often polarised around two simplistic choices: A compliance/conformance based approach that usually involves a checklist of criteria; or, some form of user testing by people who have different disabilities and/or who rely on different assistive technologies. Both approaches have their strength and limitations, and neither can provide a reliable declaration about the accessibility of a site on its own..."
- Is PDF accessible in Australia?
- By Roger Hudson, DingoAccess Random thoughts, stories and ideas from Roger Hudson of Web Usability, 21 February 2012. "More than two years ago I wrote about WCAG 2.0 and Accessibility Supported, and my fear that, 'the concept of 'accessibility supported' is not fully understood'. I believe that this 'could put at risk the whole move to improve the accessibility of the web'. I am concerned that mixed-messages relating to the status of PDF as a 'web content technology' is still causing problems within Australia at least..."
- Unusual words: accessibility for web writers, part 13
- by Dey Alexander. 4 Syllables, October 19, 2011. "People with certain cognitive, language or learning disabilities may find it hard to understand your content if you use unusual words or use words in unusual ways. Jargon and idioms are the two examples of this type of language. Avoiding jargon and idioms will make your content more accessible—and not just to people with disabilities..."
- Language of parts: accessibility for web writers, part 12
- by Dey Alexander. 4 Syllables. September 11, 2011. "If you use foreign language words or phrases in your content, you should identify them by using the appropriate language attribute in the markup for your page. This will ensure that:
- Screen readers use the right pronunciation rules for the language;
- Web browsers display the characters for the language properly. This is particularly important if the language uses a different alphabet or is read from right to left..."
- An accessibility survey for blind users
- Posted by Naomi Black, Accessibility Engineering Team. The Official Google Blog, 19 August 2011. "... This week, we're announcing a survey that will help us better understand computer usage and assistive technology patterns in the blind community...
The survey will be available through mid-September on the ACB's website and by phone. We encourage anyone with a visual impairment who relies on assistive technologies to participate; your input will help us offer products that can better suit your needs. For details, visit www.acb.org/googlesurvey..."
- Web Accessibility: 10 Common Developer Mistakes
- By Joseph C. Dolson. Ecommerce Developer, April 13, 2011. "The most common mistakes made in web accessibility have more to do with a failure to understand what constitutes accessible content than with a failure to understand the technology. To avoid gross web accessibility errors, understand one fundamental concept of web accessibility: What you see is not what you get. The problems here are non-technical and easily tested. And yet, they are very commonly overlooked from those who fail to grasp the principles of accessibility..."
- Keyboard Traps
- by Dan Stringer. Humanising Technology Blog, 13 April 2011. "... A 'keyboard trap' occurs when a person who uses a keyboard cannot move focus away from an interactive element or control using the keyboard alone. Since a keyboard trap can be so immobilising the WCAG 2.0 guidelines dedicate an entire success criterion to this issue alone..."
- Accessibility for web writers, part 5
- by Dey Alexander. 4 Syllables, April 27, 2011. "Not all web users can see or identify colours. About 8% of men and 0.5% of women are colourblind. Older people and those with partial sight may not see colours well either. And blind users who use screen readers to read web content may also miss out on colour information. As a web writer, you need to avoid creating content that relies on colour for meaning. For instance, you should avoid writing things like 'Required fields are in red' or 'error messages are shown in red'..."
- Accessibility for web writers, part 4
- by Dey Alexander. 4 Syllables, March 22, 2011. "Do you ever write instructions like these? You must fill in the red form fields; Extra training materials are in the links on the right side of the page; The arrows pointing up take you back to the top of the page. Each relies on readers having certain sensory perceptions. 'Red' relies on colour perception. 'Right' relies on location perception. 'Up' relies on perception of orientation. Sometimes you might also write instructions that rely on shape (click the round button), size (copy the large headings) or sound (the beeping sound means...). Don't assume all users have all sensory perceptions..."
- Accessibility for web writers, part 3
- by Dey Alexander. 4Syllables, February 28, 2011. "Web writers need to use HTML tags to identify certain types of information and relationships between information. For instance, headings need the appropriate heading tag because font size increases aren’t visible to everyone. Some blind people use software that reads out the headings. This gives them a sense of the document contents and structure—but it only works if heading tags are used..."
- In Search Of The Perfect CAPTCHA
- By David Bushell. Smashing Magazine, March 4, 2011. "CAPTCHAs, or Completely Automated Public Turing Tests to Tell Computers and Humans Apart, exist to ensure that user input has not been generated by a computer. These peculiar puzzles are commonly used on the Web to protect registration and comment forms from spam. To be honest, I have mixed feelings about CAPTCHAs. They have annoyed me on many occasions, but I’ve also implemented them as quick fixes on websites. This article follows the search for the perfect solution to the problem of increasing amounts of human-generated spam. We’ll look at how and why CAPTCHAs are used and their effect on usability in order to answer key questions: what is the perfect CAPTCHA, and are they even desirable?..."
- Accessibility for web writers, part 2: Text alternatives for images
- by Dey Alexander. Writing for the Web - Useful, usable, accessible. Web content that works, November 29th, 2010. "Whenever you use an image on a web page, you need to provide a text alternative—a text version of the information or function provided by the image—except when the image is purely decorative. Text alternatives are one of the most basic requirements for accessibility, but also one of the most misunderstood. Many websites have poor text alternatives..."
- Accessibility for web writers, part 1: Introduction
- by Dey Alexander. Writing for the Web - Useful, usable, accessible. Web content that works, September 27th, 2010. "Some web writers may not know how much their work can affect accessibility. That needs to change. This is the introduction to a series of articles on accessibility for web writers. I'll be using the Web Content Accessibility Guidelines 2.0 as the basis of these articles, since they are the standards Australian websites must meet..."
- As the Social Web Grows, Access Becomes a Right
- By Curt Hopkins. Read Write Web, December 15, 2010. "As the social web becomes more common, universities start to make use of it. As they do, their reliance on it grows until often the only place to access essential information is online. But what of those who cannot utilize that information in the same way as the majority of their fellows? Just as lecture halls built prior to the Americans With Disabilities Act did not come with wheelchair ramps, universities' online presence and strategy were built with equally little thought to those outside of the mean. And universities and students alike are beginning to pay the price for that oversight..."
- Accessibility myths in 2010
- by Roger Johansson. 456 Berea Street, November 9, 2010. "Five and a half years ago I posted an article about Accessibility myths and misconceptions where I tried to explain why some commonly held beliefs about web accessibility are incorrect. Early this year, Ian Pouncey posted a few other Web accessibility myths. Here is a quick roundup of the myths from these two articles..."
