We received 1121 valid responses to the screen reader survey, which was conducted Dec. 2008 - Jan. 2009.
-
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.

33 respondents (2.9%) reported being both deaf and blind.

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.

-
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.

-
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.

-
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.
