Free Accessible Web Browsers for Learners with Multiple Disabilities

Guideline 1.3 Create content that can be presented in different ways (for example spoken aloud, simpler layout, etc.) without losing information or structure

Draft Guideline 1.3 of the Web Content Accessibility Guidelines 2.0 discusses the importance of making information available in a form that can be perceived by the user– either directly or through an assistive technology. For example, if a site uses an image to convey meaning, then the alt text should be present so that it can be seen (in a text-only environment), heard (by a screen reader) or even felt (through a refreshable braille display). This pertains to both presentation and structure.

The technologies mentioned above– text-only browsers, screen readers and electronic braille– all do a good job at presenting information to the appropriate audience. However, what about users with cognitive disabilities? Text read aloud may be helpful in some situations, but what about a graphical representation of content? There are already some efforts in this area with the Communicate: Webwide symbol supported browser that claims to be able to represent over 29,000 words with symbols and while I applaud their efforts, with a Windows-only, proprietary, subscription-based product, I doubt there will be any widespread adoption in the near future.

Perhaps one day there will be an open system that will facilitate the collection and use of symbols in everyday tools. Until then, here are some other project/ideas that are exploring the use of symbols:

• Merriam-Webster Visual Dictionary
  Over 6,000 images organized hierarchically under 15 major themes
  
• Zlango Over 200 icons divided into 8 major categories developed for use on mobile devices. Read Romeo and Juliet in Zlango speak.
  
• sosymbol There isn’t a lot of information on this site, but they do have a collection of standardized icons and you can contribute your own using their online symbol creator after you have logged in.
  
• Iconfinder Icon search engine
• Symbol Signs from the AIGA 50 freely available passenger/pedestrian symbols.
• Symbols.com Simple symbols for a number of words.

From the AT TechNET @ VCU: Assistive Technology Blog, a link to Communicate: Webwide, the first symbol-supported web browser. Everything happens in the browser where you can view pages in normal view, with plain text or using symbols. Their icon library contains over 29,000 words. It also reads any text that you highlight.

Is this type of technology the answer for some users with cognitive disabilities? What about a potential user who can’t access your material even when you have gone great lengths to simplify your writing. Also, while individual sites may provide their own visual elements to represent different ideas, is their value is having a standard set of icons? Perhaps the ideas would be to allow users to associate symbols with the words themselves, or at least have the option to override the default icon.

Communicate: Webwide is provided on a subscription model and is PC-only (30-day demo available).

Does it work with any site? Probably not, from their guidelines:

While Webwide interprets clear, well-written HTML; some layouts and styles will be more effective than others. To this end, we will be producing guidelines for web designers who would like to make their information accessible through Webwide.

Hopefully their guidelines are in line with already established web standards and guidelines.
