  • 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.

  • 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. On desktop we have IAccessible2, MSAA and UI Automation (amongst others) but on mobile users are tied into one platform often only supporting one browser (such as iPhone, Blackberry RIM and others) so while desktop has opened up we find ourselves in a 1990’s type impasse with users left with little room to choose on mobile. Opera works well with VoiceOver but we have no way of telling if it works on the iPhone as it’s not supported. My hope is that with more users there’ll be more momentum behind breaking this stand off and opening up the market and ultimately giving users not only choice but portability between platforms.

  • « 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. On desktop we have IAccessible2, MSAA and UI Automation (amongst others) but on mobile users are tied into one platform often only supporting one browser (such as iPhone, Blackberry RIM and others) so while desktop has opened up we find ourselves in a 1990’s type impasse with users left with little room to choose on mobile.

  • There are two basic methods of operation for VoiceOver. One involves sliding your finger around the screen and allowing VoiceOver to announce what you’re touching. Double tapping the item you are touching, or else tapping a second finger down on the screen while touching it, will activate that item.

  • Well, it turns out you can do that. From The LABEL element in the HTML 4.01 specification: The LABEL element may be used to attach information to controls. Each LABEL element is associated with exactly one form control. The for attribute associates a label with another control explicitly: the value of the for attribute must be the same as the value of the id attribute of the associated control element. More than one LABEL may be associated with the same control by creating multiple references via the for attribute. Sounds great, doesn’t it? A quick check in graphical web browsers shows that they associate multiple labels with the input field (as evidenced by the input field gaining focus when either label is clicked). But what about screen readers? It would be so useful if this would work… Unfortunately, and perhaps unsurprisingly, it looks like it doesn’t quite work as well as you’d hope. I mentioned this briefly in Use the label element to make your HTML forms accessible, but I think it’s worth bringing up again since full support for multiple labels would help us make forms more accessible to screen reader users while keeping visual designers happy. I am far from an expert user when it comes to screen readers, but I’ve done some limited testing with mostly disappointing results. Apple VoiceOver does not recognise more than one label element associated with a form control and reads only the label that comes first in the document’s source order. JAWS and Window-Eyes both do the opposite and read only the last label when an input field gains focus. The only screen reader of those that I tested that does handle multiple labels is Fire Vox. The exact results may obviously depend on user configuration and reading modes, and there may be other screen readers that get it right, but these results indicate that screen reader behaviour is too inconsistent for multiple labels to be a reliable technique.

accessibility screen reader Fire Vox

shared by Sandra Earl on 12 Oct 10 - Cached
  • For anyone who hasn’t heard of Fire Vox, it is a free, open source screen reader extension for Firefox that works on Windows, Mac OS X, and Linux. Among other things it has support for WAI-ARIA and the CSS3 Speech Module, and is a good alternative to VoiceOver if you’re on a Mac and need a screen reader for web browsing (or testing).
  • For developers Fire Vox makes it easy to check how their sites work in a screen reader. Sure, it’s just one of several available screen readers, but this one is free and cross-platform. In other words there is no reason for you not to have it installed, so grab a copy right now.

  • Screen Reader Usage
  • 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. Individual versions of screen readers are not yet computed, but generally the majority of users are using the most up-to-date version of their screen reader.

  • How customized are your screen reader settings? (e.g., changed verbosity, installed scripts, etc.) Response% of Respondents A lot29% Somewhat40% Slightly21% Not at all7% No response4%
  • a lot or some customization was reported by only 27.6% of respondents with no disability versus 71.4% for those that reported blindness.
  • 78% of respondents reported using a screen reader on a desktop computer, 54% use a screen reader on a laptop, and 12% use a screen reader on a mobile phone.
  • No respondents who use screen readers for evaluation reported using a screen reader on a mobile device.
  • Which web browser(s) do you currently use with a screen reader? Browser% of Respondents IE633% IE768% IE82% Firefox39% Safari6%
  • Respondents with no disability were nearly twice as likely to list Firefox as blind respondents - 66% to 37%.
  • The percentage of Safari users is over double that of the overall population - this may be due in part to the fact that some in the Mac community actively solicited survey participation and encouraged respondents to indicate their Safari use, perhaps partially due to feeling snubbed because we didn't list them with IE and Firefox as direct choices.
  • When first accessing a new, unfamiliar home page, I'm most likely to... Response% of Respondents Read through the home page46% Navigate through or listen to the links on the page35% Use the Search to find what I'm looking for13% Look for a site map or site index3% No Response2%
  • Interestingly, the more proficient screen reader users are more likely to read through the home page and use links less often than less proficient screen reader users. This may be due to faster reading speeds for more experienced users. The home page strategies used were very similar regardless of proficiency, disability, or amount of screen reader use.
  • I use "skip to content" or "skip navigation" links... Response% of Respondents Whenever they're available22% Often16% Sometimes28% Seldom19% Never10% No Response4%
  • Some questions were of a technical nature and we understand that many participants may not have been very technically savvy. Responses may also be based upon user experiences with web content that is generally inaccessible. We cannot help but wonder if responses may have been different if screen reader interactions with web content were typically very positive.
  • I use Access keys... Response% of Respondents Whenever they're available22% Often16% Sometimes28% Seldom19% Never10%
  • I navigate by headings... Response% of Respondents Whenever they're available52% Often24%
  • 76% always or often navigating by headings when they are available.

  • Find the word "Search"18% Jump to the first text/edit field on the page25%
  • Jump to the first form element in a page36%
  • Proficient screen reader users were more than twice as likely to jump directly to the form or text/edit field than less proficient users. Less proficient users were nearly three times more likely to use more manual methods (reading, tabbing, or finding) than more proficient users.
  • a majority of respondents seldom or never use site maps. There was no marked difference in the use of site maps across screen reader proficiency or disability. In general, it appears that site maps may be beneficial, but are not commonly accessed by screen reader users.
  • Text-only versions are always used by many and never used by many. As such, it is very difficult to interpret the value they have for screen reader users. More proficient screen reader users were much less likely to use text-only versions than less proficient users. This may suggest that proficient users employ sufficient techniques to render the main version acceptable to them. Or, it may suggest that proficient users do not gain value in using text-only versions, which are often less than optimal.
  • If content is identified as being "for screen reader users", how often do you use it? Response% of Respondents Whenever it's available38% Often15% Sometimes25% Seldom13%
  • A closer analysis, however, reveals that pop-up windows are reported as very difficult twice as often by less proficient screen reader users than with higher proficiency. Alternatively, more proficient users were three times more likely to indicate that pop-up windows are not at all difficult. This shows that less proficient screen reader users (which represent 41% of respondents) have more difficult experiences with pop-up windows.
  • Firefox users were much more likely to give a favorable response, perhaps a reflection of Firefox support for ARIA, etc. Evaluators and those without disabilities were nearly twice as likely to indicate that these applications are not very or not at all accessible than those that always use screen readers or have disabilities. This may suggest that these applications are actually more accessible than evaluators believe them to be, or alternatively, that screen reader users with disabilities are less knowledgeable about the true inaccessibility of these technologies.
  • 66% of evaluators preferred that the image be ignored, compared to only 28% of those that always user a screen reader. Similarly, 65% of those with no disability preferred that the image be ignored, compared to 29% of those with disabilities.
  • If a web page contains a photo of the White House, I prefer that the image be identified as... Response% of Respondents Photo of the White House80%
  • 69.4% of evaluators found them difficult compared to only 42.6% of those that always use a screen reader. Those with higher screen reader proficiency naturally found these links easier.
  • 71.5% of screen reader users reported that Flash is difficult
  • While the majority (58%) of users reported that frames are easy, those that are blind were 3 1/2 times more likely to indicate that they are easy than those with no disability. Similarly, those that always use a screen reader reported frames as easy nearly 3 times more often than evaluators. This perhaps suggests a misconception among those that do not have disabilities that frames are very inaccessible when in fact those with disabilities find them easy.
