Social Networking Accessibility

Via Accesssites.org, a summary of a 21 page report on the accessibility of social networks from AbilityNet. The report analyzes Facebook, MySpace, YouTube, Yahoo and Bebo and reports that they all stink. Of those 5 sites, Yahoo was the only was to receive a two-star rating– that’s two starts out of five. The other four all received one star indicating they are ‘very inaccessible’.

The Dataportability.org group has been in the news of late as a number of major social networks have become involved. While their stated mission is not to make social networks accessible for users with disabilities, the goal that they are working towards should have that overall effect over time. They are working to promote the use of existing open standards to facilitate the sharing of social network user content outside of that network. Over time this will open the door to the creation of more accessible interfaces to access at least some of the data that is currently available only through proprietary, inaccessible systems.

Hopefully, the process of making user content more readily available will also lead to improvements in accessibility along the way. In the meantime, are users with disabilities being left out of the social networking revolution? Is anyone doing this right?

Accessible Pen and Paper?

I first heard of Livescribe from an announcement of their upcoming ‘smartpen’ and noted that a former professor, Andy Van Schaack, PhD was involved in the project. A few weeks ago, I was able to attend a presentation from Dr. Van Schaack and learned a little more about the project. I was especially interested in the note on the presentation flyer that said he would “present his current NSF–funded study on the use of the smartpen to support blind college students in science, engineering and math.”

He started off with promotional information about how the Livescribe system is a new computing platform with a great team behind it. By all accounts it appears to be a laudable effort in the arena of comparable smart pen technologies. It works by recording audio while using the pen on special paper. You can then go back to any point in your notes, tap on the page and listen to the corresponding audio. Your notes also become searchable and shareable.

Then he addressed how the project would help make content accessible for students who are blind. Currently, a student who is blind studying in a field that requires the use of graphs or diagrams would need a technology toolkit such as a laptop paired with a not inexpensive tactile talking tablet. The price point lowers significantly as students are able to use the Livescribe pen with the more affordable Sewell raised-line drawing kit. This combination of technology allows the students to draw and annotate a graph with the ability to reference the graphic later and access whatever audio was recorded at the time.

Too Much Accessibility

Hopefully, anyone subscribed to this blog also follows 456 Berea Street. If not, you missed a great post from Roger Johansson titled Overdoing Accessibility. Go read the article and then subscribe to his feed.

Mike Cherim tackled the same subject awhile back on Avoiding Extreme Accessibility.

Bim Egan ran a whole series of articles titled Too much accessibility — TITLE attributes.

The two attributes that were on all three lists were tabindex and accesskeys. The lesson? Take the time to understand your users, then evaluate the work that you are doing to make sure it is actually helping those you are trying to help.

Icons, Symbols and Cognitive 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:

Online Video Captions

Google, Microsoft, Yahoo and AOL have announced their participation in the Internet Captioning Forum (ICF) established to promote the use of captioning for online video. They will be working with the National Center for Accessible Media (NCAM) at WGBH Boston. You can read quotes from Vint Cerf and other representatives from each of the big four at the National Center for Technology Innovation regarding the effort.

I am neither deaf or hard or hearing, but the captions are almost always on when the television is on in our home. I enjoy the viewing experience and miss fewer words mumbled here and there when I can look down and glance at the words when needed.

Google video currently provides detailed instructions on adding captioning to videos. Additionally, in the Google Video Help Center, this questions is asked, “Do you generate captions/subtitles for my video?” and the answer they provide is a promising “Not at this time.” They also have a section where you can view examples of captioned videos.

Alt Text, Less Can be More

Aaron Cannon at NorthTemple.com offers insight from the perspective of a blind user on the importance of alt text. First from Aaron, as quoted by Ted Boren:

For some reason, some folks get it into their heads that being blind is really terrible and the only way our lives can be whole is for us to have all the pretty pictures in the world described to us. Where, in actuality, most blind folks couldn’t care less about most of it.

Aaron then expounds:

…if there was a picture of a man using a particular product, I’m really not interested in hearing “picture of a man looking pleased as punch to be using the new ultra-lite USB hair drier,” or worse, “picture of a man.” I really don’t care about what image the designers chose to use as eye-candy. I can’t see them, and descriptions of meaningless images just waste my time and delay my getting to the information I’m really interested in.

Read the entire post for an apt comparison of web accessibility to bread making. Thanks Aaron, I’ll think twice the next time I feel an urge to wax poetic in my alt text.

Accessibility guidelines make clear that null alt text should be used for images that do not convey meaning, decorative images. Is the point at which an image goes from meaningful to meaningless unclear to anyone else?

Using Symbols to Access the Web

Picture of the Webwide Browser

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.
