adobe air accessibility online help

  • We considered a few approaches, but decided to grow our new widget out of Adobe Flex and Adobe AIR. This is firstly because these tools met our requirements to work cross-platform and deliver the desktop experience we wanted, and also because they linked up with in-house skills in the team which manages them, making them simpler to manage.
  • BBC Future Media & Technology's pilot widget application BBC LiveUpdate uses the Adobe AIR runtime, which is dependent on users downloading and installing a plugin to their desktop, but which unfortunately does not currently support screenreaders (or other software which relies on the Microsoft Active Accessibility layer for assistive technologies). We're working with Adobe to make tools built with AIR more accessible than current products wherever possible and are committed to delivering accessible services. As this is a beta product, there are also other limitations in how much we have been able to establish accessibility support in the following areas:Colour contrast cannot be alteredText size cannot be alteredLacks consistent alt textLacks Title attributesIs not entirely tabbable.

  • One way to put a name to this activity is to say that we are going up the mountain — in other words, moving upward is our goal. Another is to refer to reaching the summit — the destination to which we aspire. The former says, in effect, “We are gradually making our way up the hill.” The latter says, “We’re not done until we get to the top.”
  • Inclusive design is the practice of going up the mountain — we can always look for ways to include more people and situations to our designs, even if the result only gets us a few steps up the trail at a time.
  • I would go so far as to say that it’s the scope of that task — the seemingly infinite nature of including everyone — that is too big of a challenge. We aren’t all born to be mountain climbers. But together we can get a little farther up the hill, if we try.

    My post on the @adobe blog is up. It's about how I distinguish inclusive design from accessibility, and why you still need to go back and learn about universal design. https://t.co/OsjUp57F29 #a11y #inclusivedesign Great article on the nuances between A11y, Inclusive Design and Universal Design.

  • 3. Easy conversion of existing Flex or HTML applications. It’s the same basic runtime. In the case of HTML, AIR apps rely on WebKit, the core component in Apple’s Safari web browser.
  • 7. Rich design and multimedia. This is Flash, so ideal for highly customized UIs, animation, sound and video. Adobe is proving the point by creating a media player built with AIR. Existing Flash developers can easily use their skills to build AIR applications.
  • 4. Proprietary technology. AIR applications depend on Adobe’s runtime.
  • ...3 more annotations...
  • 6. No model for commercial components. It is not clear to me how a component vendor could sell an AIR component while protecting it from unlicensed deployment. This may limit the availability of 3rd party components, with a corresponding impact on productivity.
  • 7. Schizophrenic development model. AIR supports either Flex development, or HTML applications which run in WebKit. The ugly side of this flexibility is that there are two SDKs, even two JavaScript virtual machines with different capabilities and characteristics. While it is nice to have a way to render HTML, I am not convinced that the web application model is worth it, given the complications it causes. After all, web applications run perfectly well in the browser.
  • Lack of UI standards may lead to annoying inconsistencies between AIR applications. We are used to this on the Web; now it is coming to the desktop as well.

  • Christian asks what would be the open-source equivalent of AIR? XUL says Ian. Christian says that AIR is built on HTML, CSS and JavaScript so once the player gets keyboard access it will be quite accessible. Ian responds that he looked on the Adobe site for accessibility info on AIR and the fact that he found nothing scared him.

  • Most people who are blind will rely on screen reading software such as
  • JAWS or Windows-Eyes

  • 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.

  • Captivate has a number of accessibility features in version 3 and 4 although there are some issues that Adobe is working on.
  • Ensure that the “enable accessibility” checkbox is checked under the File > Publish settings in order for accessibility to be exposed to assistive technologies.
  • Slide Accessibility Text Each slide can contain accessibility text. This can be added by going to the slide properties, activating the Accessibility button and entering text in the text field.
  • ...6 more annotations...
  • Closed Captioning Closed captioning can be added to all audio files. From the record audio dialog, closed caption text can be added under the Caption tab. The playback bar contains a CC button which allows the closed captioning to be displayed or hidden.
  • Button Accessibility Text buttons can be made accessible. The text that appears on-screen becomes the button’s accessible name. To make the buttons keyboard accessible, the “Set Keystroke: Select Keys” button should be used and the keystroke of “enter” should be set in the object’s properties dialog. Other shortcuts can be assigned but enter/space will then not work to activate the button after tabbing to it. The keystroke of “enter” can be assigned to multiple buttons and the button with focus will be activated when Enter is pressed.
  • Audio recordings can be associated with click boxes and thus authors can associate descriptive text to be announced when a shortcut keystroke is pressed to assist users with visual impairments.
  • Text from PowerPoint Much of the text from PowerPoint will come through as text in Microsoft Active Accessibility (MSAA) and will be exposed to users of screen readers. Currently there isn’t a method to change the order or edit this text.
  • Quiz Questions There is some accessibility support for quiz questions. Simple types of questions such as true and false and multiple choice provide accessible names for the radio buttons and the text of the question appears as text in the accessible MSAA structure and is exposed to screen readers.
  • Accessibility Differences Between Captivate 3 and 4 The text in the “text caption” object does not show up as accessible text in Captivate 3 but does in Captivate 4. In addition, it is not possible to set accessible text for specific images in Captivate 3 but it is possible in Captivate 4.
