  • JAWS or Windows-Eyes
  • ...41 more annotations...
  • refreshable Braille device which converts the text on the website into Braille.
  • Place form instructions before the form field
  • To improve accessibility and usability for screen reader users, form field requirements must be placed before the form field itself.
  • Provide a ‘skip to main content’ link Screen reader users benefit from a ‘skip to main content’ link as it enables them to jump over lengthy navigation to the main content of the web page, reducing the amount of content they have to listen to.
  • Ensure link text is descriptive Screen reader users using software such as JAWS can listen to the links on a web page through functionality known as a links list. If link text is not descriptive—solely using phrases such as “click here” or “more information”, for example—there is no way for screen reader users to determine where the link will take them.
  • Provide descriptive web page titles The first piece of information a screen reader user will listen to when they open a web page is the <title> assigned to the page. It is important, therefore, to use a title which reflects the content of the web page.
  • Provide descriptive headings It is important to provide descriptive headings
  • Screen reader users often listen to headings out of context from the main content
  • Provide audio descriptions and transcripts of video content Screen reader users depend on audio descriptions to provide additional information about important visual content displayed within a video.
  • Transcripts are written accounts of the video or audio content and can include additional information such as comments and descriptions
  • screen reader users cannot use a mouse
  • People with low vision will tend to use magnification software to make reading a website easier. Depending on the severity of their vision impairment, these users may combine magnification and screen reading software by using software products such as Supernova or ZoomText. For milder vision impairments, users may just increase the default size of text within their browser settings or change the colors to make the content more comfortable to read.
  • Avoid using images of text
  • Ensure text can be resized
  • Place key information in specific locations of the screen
  • ebsite search functionality is often located in the top-right corner of the web page
  • Juicy Studio color contrast analyzer.
  • it is possible to determine whether the colors chosen meet the minimum requirements specified in the WCAG Guidelines.
  • People with a hearing impairment tend not to use assistive software to improve their web browsing experience. Instead, they rely on the website being accessible by providing any audio content in alternative formats, such as captioning or transcripts.
  • By making audio content accessible for users with a hearing impairment, it also makes the content accessible for other users who find themselves in an environment where audio cannot be heard.
  • library with the sound turned down; they may be in a noisy environment where it is difficult to hear the audio; or they may be using a computer without speakers.
  • Provide captions for any video content
  • Provide transcripts of the spoken audio Where content is spoken without video, such as in a podcast, it is important to provide a transcript. It is recommended that the transcript be provided in plain accessible HTML to allow access by the widest possible audience, as opposed to a Microsoft Word or Adobe PDF document.
  • Physical disabilities range in severity from those who are temporarily disabled, for example having a broken arm, to those who are quadriplegic and have no use of any limbs. Depending on the severity of the physical disability, these users may access websites through voice recognition software such as Dragon Naturally Speaking.
  • However, what all users with a physical disability have in common is limited or no ability to use a mouse. This means that content within the website that requires a mouse click or fine motor control cannot be accessed by these users.
  • Ensure all content can be accessed via the keyboard
  • Users with a physical disability will have limited or no ability to use a mouse and as such will navigate websites using the keyboard.
  • Provide a focus state for links
  • Provide visible skip links Skip links are links that become visible when they receive focus, and are helpful for users with a physical disability. Keyboard users must tab through the web page to reach the particular link they are interested in—skip links allow lengthy navigation to be bypassed and reduce the number of key presses required to activate links in the main content.
  • Avoid moving targets Avoid using moving targets such as tickers, as users with a physical disability can find them very difficult to use.
  • Provide large clickable areas
  • provide sufficient whitespace between links
  • People with a cognitive or learning disability may have difficulties with memory, problem solving, perception, and conceptualization. In addition, people with a learning disability may have issues with reading and comprehension such as dyslexia.
  • To enhance the usability of the website for these users it is important that content is written in plain English, page layouts are simple in design, navigation is clear and consistent and there is no moving content to impede comprehension.
  • Provide the same look and feel throughout all pages of the website. Ensure that the navigation and main content are located in the same area of every page. Additionally, consider color coding different sections within the website. Users with cognitive or learning disabilities tend to find it easier to navigate around sections which are color coded.
  • Provide a site map A site map will enable users with a cognitive or learning disability to have a clear idea of the breadth of content contained within the website. The site map also enables users to directly access any page on the website, and helps if the user becomes lost.
  • Use a resizable sans-serif font which is left-aligned To increase readability for users with a cognitive or learning disability, use a sans-serif font which can be resized. Additionally, left-align content—justified text is more difficult to read due to the uneven spacing between words. Italicized and capitalized text should also be kept to a minimum to aid readability.
  • Provide helpful error messages
  • Offer speech output Organizations such as Browse Aloud and Textic enable content from a website to be spoken when highlighting the words on a web page. Offering this functionality is especially helpful for users who find it difficult to read large amounts of text.
  • Provide an Easy Read Version Consider providing an ‘easy read’ version of complex content. This combines plain text with images to aid understanding of the information. For an example of an easy read document see the Department of Health’s Making Lives Better for People with a Learning Disability.
  • Provide different color schemes People with cognitive or learning disabilities may benefit from different color scheme options. It is helpful if an easy read scheme such as a lemon background with dark text, and a hi-viz scheme such as a black background with yellow text, are provided.

accessibility elderly general WCAG 2.0

  • One major new piece of work undertaken by WAI is the EC-funded WAI-AGE Project (http://www.w3.org/WAI/WAI-AGE/), a look at the implications of an ageing population for web access, given the older people are more likely to have disabilities and may also be less familiar with new technologies. “Demographics worldwide are dramatically changing at the moment,” says Andrew Arch, who works with Abou-Zahra on WAI-AGE. “The proportions of older to younger people are changing as well as the numbers. We’re living longer, and we haven’t got the support behind us. “Lots of things have got to change in governments and organisations - with an ageing workforce, you have to keep learning to stay accessible.”
  • The WAI-AGE project is partly aimed at finding out whether there are any significant new pieces of work needed to ensure web accessibility for an older population, Arch says. “We’ve looked at what research and user observation has gone on over the decade. There is a pretty big overlap between older people and others with disabilities - sight starts to decline, motor dexterity - and individually these overlap. But with older people there is often a lack of recognition that there is a disability there. For example some people might just say they can’t remember so well, rather than that they have a cognitive impairment. Or people won’t see failing eye-sight as a disability, it’s just ‘part of growing old’. But they are disabilities, and often multiple disabilities.”
  • Having gained a grasp of current research the project returned to guidelines such as WCAG 2.0 to see if any changes might be needed. “A large proportion of the needs of older people are met by the new guidelines, but other things might need to feed into the guidance we will issue on implementing the guidelines, for example guidance on how people prepare content for older people.,” said Arch. “Many older people have not grown up with computers, and may not realise their capabilities, for example that you can magnify text in your browser.”
  • ...4 more annotations...
  • This argument is a development of the age-old mantra from the accessibility sector that people with disabilities want to use the web in the same way as everybody else - “it is a human right recognised by the UN,” says Abou-Zahra. But he recognizes that businesses in particular will also  be interested in the additional business benefits, especially in the current financial climate.
  • “With commercial organisations the return on investment is often an important argument. Well, a few years ago, companies might have said ‘how many older people are online?’ but with demographics changing they know the answer. And with the current surge in mobile phone use there is another incentive, since accessible sites work better on mobile phones.”
  • Another change of style will be a greater separation between the core guidelines and references to specific technologies such as Javascript or browser types, Abou-Zahra says.
  • “WCAG 1.0 was too  technology-specific. Back then HTML was more dominant, and there was less use of multimedia, but today we have a flurry of technologies such as Ajax, so the first lesson we learned is don’t write for a specific technology. Also, in the days of WCAG 1.0 we had to exclude Javascript because it was not sufficiently standardised and  assistive technology could not handle it consistently, but now that has largely changed so you need to include it, to look at how any technology should be accessible. The requirements - such as tagging images with text - needs to apply to any technology you are using.

  • Screen readers are very literal and, as such, tend to read out numbers in a list with no particle words or punctuation.
  • Using a CSS technique to position text off the screen, it’s simple to add some particle words (such as “from” or “to”) for screen reader users. In the case of a range of numbers, the dashes can be presented using graphics and not part of the text content of the page. For example, in the second data point shown in the image below, instead of a screen reader announcing “twenty-six percent fifty-five sixty-four” it would be “twenty six percent fifty-five to sixty-four.”
  • Another example is implied headings. Sighted users can understand quickly from images that a data set title should be “gender” but if the heading doesn’t appear in the design, it should be added and visually hidden using CSS.

  • In tandem with the launch of their 3G mobile website, Siminn also launched a slightly lighter version of the same site - a 2G-optimized mobile presence to serve less powerful phones. Both sites are anchored to the same reservoir of information, but the 3G site makes less-restricted use of CSS, images, and other coding ornamentations.
  • The only distinction Siminn makes concerning the dimensionality of the user-experience is whether the device is 2G or 3G enabled. As stated before, 2G devices are sent to a slightly lighter version of the 3G site
  • This is exactly what Siminn are doing. By detecting the type of phone, they are presenting the customer with the most appropriate version of the page – either the 3G enhanced or the more basic design.

  • e chose not to try and replicate the entire Icelandair website, but rather to cleave from it four or five of its most crucial elements.
  • This page contains the only form on the mobile site. In general, forms should be avoided because form input via a mobile device can be a tricky endeavor. However, there are certain coding practices that can simplify form input. For example, if your form field should only accept numeric input, then you should make use of the -wap-input-format property of WAP CSS. The Apple iPhone will automatically set the input to numeric if the name of the input element is set to certain values - phone or zip for example.
  • Mobile users only need to be shown news items that have some inherent urgency.
  • Much like your desktop browser recognizes a mailto: link as an email address, mobile devices recognize tel: links and phone numbers.
  • Do not assume that just because the UA string is not in your enumerated list of “Accepted strings”, it is not possible to view the site.
  • This is where you build in progressive enhancements to the website experience.
  • WURFL is an open source list of known phones and their capabilities. This can be put into a database and when a mobile device visits the your site you can sniff the UA, look-up the capabilities of that device (including screen-dimensions, default browser, etc) and serve them the best possible experience.
  • The RDF vocabulary is a standard across many mobile devices. Vendors that use this approach allow mobile sites to keep up-to-date with any new devices, without having to keep their own database of device types.
  • ou can find more details about standards support in Opera Mini/Mobile 4 here: Designing with Opera Mini 4 in mind JavaScript support in Opera Mini 4
  • There are a few basic coding items to avoid in the mobile web space. Chief among these, at least for now (now being 10/2007), is client-side scripting.
  • While it's tempting to try and port that elegant bit of AJAX from your conventional web to your mobile web, you will only create headaches for yourself.
  • ome browsers do support various levels of JavaScript, but as a developer you should not expect it to work across all devices.
  • retty heavy processor hog, so continuous scripting can drain a battery fast
  • mobile browser support for stylesheets varies greatly.
  • keep things simple.
  • most mobile devices default to their own font sizes and families regardless of styling. Thus, when working on the Siminn project we made no attempt to influence font size or family. In cases where we wanted a larger font, we simply relied on the generic XHTML heading elements.
  • he inclusion of font-size=smaller in the body tag worked as a kind of global reset for font sizes in every device we tested. With this little bit of code we were able to sufficiently reduce the default font size and thus more faithfully reproduce the design that we had been tasked with coding.
  • XHTML-MP - the mobile web subset of XHTML - is fully supported on most modern devices.
  • You can't read 2 books and several articles about mobile web development and cover everything. Much of the effort is trial and error. When starting out, emulators are a good way to get a rough idea of how the site will work. It gives you some feel for the navigation, architecture and flow of the site, but the look and feel varies from the emulator to the real device. The best thing you can do is get a few real phones to test on. I'm sure between yourself, co-workers and a few friends, you can manage to test your site on a good cross-section of the phones out there. Finally, there is some help. The W3C mobile web initiative does have a checklist to see how well your site is doing and so does dev.mobi - if you take heed of these two lists, your site should give a quality experience to most customers.

  • Vernon Fowler on 02 Oct 18
     
    There are various techniques to visually hide content in our web interfaces, but are you aware of the different effects they have on the accessibility of that content? While it would be nice if there was a single, native, solution for hiding content, there are contextual benefits to the various techniques at our disposal. Since there have been many articles already written about these techniques, over the many years they've been in use, the focus of this article will be to highlight the ones that are most appropriate for modern web development. We won't just look at the code behind each of these techniques, instead we'll focus on why each technique has its place, using practical examples to demonstrate their purposes. But before we talk about how to hide content we should ask ourselves a question… Why are we hiding content?

  • Include the current page as the last item in the breadcrumb trail.
  • Breadcrumb trails should start with a link to the homepage.
  • ...14 more annotations...
  • Breadcrumbs aren’t necessary (or useful) for sites with flat hierarchies that are only 1 or 2 levels deep, or sites that are linear in structure.
  • Unfortunately, on mobile, the cost of using breadcrumbs can quickly overwhelm the benefits. Don’t use breadcrumbs that wrap to multiple lines.
  • Don’t use breadcrumbs that are too small or too crowded together.
  • Consider shortening the breadcrumb trail to include only the last level(s).
  • The Oregon state government website includes a breadcrumb trail, but omits a link to the homepage. However, in this case this is acceptable, as the site also includes a Home link in the global navigation
  • duplicating the Home link in both the global navigation and the breadcrumb trail is not recommended — one or the other is fine
  • This site’s structure is nonhierarchical, and so there is no need (or value) in including a breadcrumb trail.
  • MIT’s main website has a flat hierarchy, with only 1 page in each section. While it features a breadcrumb at the top of the page, this breadcrumb isn’t necessary. In the main navigation, the location of the page is highlighted.
  • Breadcrumbs should include only site pages, not logical categories in your IA.
  • The link to the parent page is a dropdown menu, with the current page’s siblings (bottom image). A better design would  have a separate UI for the local navigation, to enable users to travel to lateral pages in the current section of the site.
  • Breadcrumbs should not replace the global navigation bar or the local navigation within a section.
  • Breadcrumbs augment but do not replace those main forms of navigation.
  • when they skip some of these levels (for example, because they arrived to the site by clicking on an external link such as a search-engine result), breadcrumbs orient them and help them find their way to other, possibly more relevant, pages.
  • In this example, the home page and current page are omitted from the breadcrumb trail, which is not recommended.

accessibility html5 browser

shared by Vernon Fowler on 24 Nov 12 - No Cached
  • The situation for new HTML5 elements is different and likely to remain so for some time. It will be years before New HTML5 elements get robust accessibility support implemented across browsers and platforms. This is particularly so for non interactive elements such as the new HTML5 structural elements because  accessibility APIs in general do not have defined roles for many non interactive elements. In this case it is recommended to add the appropriate ARIA roles to elements that are meant to convey meaning but are effectively meaningless due to lack of implemented accessibility support. For example, adding role=navigation to a nav element fills the gaps in support for HTML5 semantics as ARIA  is more robustly  supported by most modern browsers and assistive technology:
  • <nav role=”navigation”>
  • Authors/developers can safely assume that any element that has been around since HTML 4.0 is already accessibility supported in browsers that support accessibility. So they do not need a default implicit role added.

  • « Yay factor! Going global with standards and BBC Click on web accessibility Make video accessible, localised, mobile and searchable by captioning » Screen reader software usage shifts on desktop and mobile Nov 4th, 2009 by iheni WebAim released their 2009 Screen Reader Survey last week, a follow up from last years Screen Reader survey. Very good reading it makes too but of particular interest are results around screen reader choice on the desktop and increased screen reader access on mobile. For years it’s felt like screen reader users have mainly used IE on the desktop in combination with the major screen readers Jaws by Freedom Scientific and WindowEyes by GW Micro. It’s not that other platforms don’t support screen readers (we have Orca on Linux, VoiceOver on Mac) it’s just that IE seems to have dominated. As such what types of content and web technologies users can and can’t access has very much been driven by what the three software vendors Microsoft, Freedom Scientific and GW Micro have supported. This has made access to the open web a bit lopsided cutting down on choice for the end user, competition and by extension innovation. SVG is an example of a web technology that has possibly suffered by not being supported by IE and in turn by Jaws and WindowEyes. What’s interesting to see in this year’s survey is that Jaws and WindowEyes – while still the most used – have some stiff competition at snapping at their heels from open source, free screen readers (NVDA and  SAToGo ) and VoiceOver which is available with Mac: JAWS 75.2% Window Eyes 23.5% VoiceOver 14.6% System Access or System Access To Go 22.3% NVDA 25.6% While this year’s stats show little shift for Jaws and WindowEyes usage overall there is a significant leap forward for NVDA (NonVisual Desktop Access) and VoiceOver: Of the 1121 respondents, 74% use JAWS, 23% use Window-Eyes, 8% use NVDA, and 6% use VoiceOver. While several other screen readers were reported, these were the most prominently reported. The upsurge in VoiceOver could be explained in part by iPhone now providing VoiceOver support; all of a sudden there is a very real reason to switch to Mac if you can use a screen reader you are familiar with on both your desktop and mobile. This could also explain the increase of screen reader users on mobile reported this year with 53% of survey respondents with disabilities confirming they use a screen reader on a mobile device. This is up from 12% last year (although last year’s survey doesn’t distinguish disabled from non-disabled users). I wonder how much this is to do with the ‘iPhone Factor’ but also can’t help thinking that social networking has done for the mobile web what Kylie Minogue did for Agent Provocateur – everybody wants some. And for me at least 2009 feels like the year that we all sat up and paid attention to the potential of mobile for people with disabilities. We’re still faced with one massive problem with mobile access however and that’s the lack of an open, cross platform accessibility API that mobile screen readers can hook into.

  • 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.

  • An attempt to redefine or reframe the term ‘disability’, in the context of online learning as a mismatch between a learner’s needs and the education process delivered, is enshrined in a new international e-learning standard.
  • The standard says it views disability as “a consequence of a mismatch between the learner’s needs (or preferences) and the education or learning experience delivered. “For example, an individual who is blind is not disabled when the lesson is delivered in audio. However, an individual who does not have the necessary background knowledge to understand the lesson, or who is listening to the lesson in a noisy environment, is disabled. “Thus, the needs and preferences of a user may arise from the user’s context or environment, the technical requirements of the user’s device, the tools available (e.g. assistive technologies such as Braille devices, voice recognition systems, alternative keyboards, etc.), the user’s background, or a disability in the traditional sense. “Given this reframing of the meaning of “disability”, a learning environment is deemed as “accessible” when learner needs can be addressed or matched.”

shared by Vernon Fowler on 20 Aug 14 - No Cached
  • tabindex="0" and tabindex="-1" have special meaning and provide distinct functionality in HTML. A value of 0 indicates that the element should be placed in the default navigation order. This allows elements that are not natively focusable (such as <div>, <span>, and <p>) to receive keyboard focus. Of course one should generally use links and form controls for all interactive elements, but this does allow other elements to be focusable and trigger interaction.
  • A value of 0 indicates that the element should be placed in the default navigation order. This allows elements that are not natively focusable (such as <div>, <span>, and <p>) to receive keyboard focus.
  • A tabindex="-1" value removes the element from the default navigation flow (i.e., a user cannot tab to it), but it allows it to receive programmatic focus, meaning focus can be set to it from a link or with scripting. This can be very useful for elements that should not be tabbed to, but that may need to have focus set to them. A good example is a modal dialog window - when opened, focus should be set to the dialog so a screen reader will begin reading and the keyboard will begin navigating within the dialog. Because the dialog (probably just a <div> element) is not focusable by default, assigning it tabindex="-1" allows focus to be set to it with scripting when it is presented.

  • A value of -1 can also be useful in complex widgets and menus that utilize arrow keys or other shortcut keys to ensure that only one element within the widget is navigable with the tab key, but still allow focus to be set on other components within the widget.

  • To enable subtitles by default, you will need to use &cc_load_policy=1 parameter
  • 3. Linking to Videos with Captions If you want to share a link to the video for viewers to see captions by default, you need to add this code at the end of the URL string: &yt:cc=on
  • &yt:cc=on

      If there aren't any existing URL parameters, instead of appending &yt:cc=on you may need to use /?yt:cc=on For example https://youtu.be/GUfCPMCMORM/?yt:cc=on

  • To recap, the placeholder attribute: Can’t be automatically translated; Is oftentimes used in place of a label, locking out assistive technology; Can hide important information when content is entered; Can be too light-colored to be legible; Has limited styling options; May look like pre-filled information and be skipped over.
  • Move the placeholder content above the input, but below the label:
  • Development Here’s how to translate our designed example to code:
  • ...4 more annotations...
  • aria-describedby ensures that the p content will be described last, after the label’s content and the kind of input it is associated with.
  • By using aria-describedby to programmatically associate the input with the p element, we are creating a priority of information for screen readers that has parity with what a person browsing without a screen reader would experience.
  • The floating label effect, a close cousin to this phenomenon, oftentimes utilizes the placeholder attribute in place of a label, as well.
  • Content hidden by an on-screen keyboard. 3rd party keyboards with larger heights may have a greater risk of blocking important content.

    Not only argues for not using the placeholder attribute but also describes an inclusive input hint and how to code it.
