Accessible Web Browsers

I have mentioned a symbol-based browser before, but here is a list of three different accessible browsers:

Free Accessible Web Browsers for Learners with Multiple Disabilities

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.

Additional Resources

(Update) Andy sent me a couple of additional links to share:

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:

Tactile Video Displays

a tactile graphic display device

The National Institute of Standards and Technology has licensed a technology for the commercialization of a tactile graphic display device. The device promises users who are blind the ability to feel images from any number of sources on a refreshable braille display. The technology has been in development for awhile, but commercialization is a significant step forward.

From the press release:

ELIA Life Technology Inc. of New York, N.Y., licensed for commercialization both the tactile graphic display device and fingertip graphic reader developed by NIST researchers. The former, first introduced as a prototype in 2002, allows a person to feel a succession of images on a reusable surface by raising some 3,600 small pins (actuator points) into a pattern that can be locked in place, read by touch and then reset to display the next graphic in line. Each image—from scanned illustrations, Web pages, electronic books or other sources—is sent electronically to the reader where special software determines how to create a matching tactile display.

From the ELIA Life Technology About Us page:

The ELIA Life team strives to improve the quality of life of visually impaired persons and their family members by enabling the visually impaired to live, work, learn, and communicate with greater independence and dignity.

It appears that they market the tactile alphabet as an alternative to braille and claim that, “only three percent of legally blind Americans can read Braille”

I don’t know how long before this technology will be made widely available, but it raises a couple of interesting questions:

  1. Would you prefer effective alt text to a tactile graphic display device that worked?
  2. Will this type of technology one day be used as an excuse for people not do use alt tags?

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.

Text to Speech Software and Voices

I’m trying understand a little more about Text to Speech technologies, and and came across a couple of helpful links: a Speech synthesis page from Wikipedia and a Text-to-Speech page at SNOW. It appears there are a number of different text to speech software packages available.

The issue seems to be further complicated in that at least some of the software/voice packages appear to require a license based on how many times a user distributes a voice recording.

My last concern is how to select a voice to use- it looks like a number of different options available. To save you some time, if you are looking for IBM’s natural voices the first page I came across was their AT&T Text to Speech Research Lab which took me to their official AT&T Natural Voices page and from there to Wizzard Software where you can actually purchase a product- although I still wasn’t sure exactly what…

Anyways, I am looking for some help on this one- does anyone know of any good resources, have a favorite piece of software of favorite voice? If not, I don’t know how updated this is, but it looks like a good place to start.

As a sidenote, I wasn’t even aware of the W3C Speech Synthesis Markup Language (SSML) – looks really interesting.

Evaluating Websites for Accessibility with Firefox

From the intro to the article:

Patrick H. Lauke outlines how Mozilla Firefox can be used in conjunction with the Web Developer Toolbar to carry out a preliminary accessibility review

Speakwire – Online RSS Reader

Done by the same folks who are behind Speegle, the talking search engine, Speakwire is a free online tool that reads aloud a rss feed. From their press release:

Most people associate computer speech with visually impaired users. I think that is missing the point and we set out to demonstrate just how universal speech is. It’s the nearest eqivalent to a common currency and can be exchanged and undersood as easily. Speech is mightier than the pen.

Accessible Online Slide Presentation Tool

Or perhaps better stated by the author of the tool, A Simple Standards-Based Semantic Slide Show System or S5. In Eric’s own words:

With one file, you can run a complete slide show and have a printer-friendly version as well. The markup used for the slides is very simple, highly semantic, and completely accessible… It’s totally simple, and it’s totally standards-driven.

You really should at least check out the demo to understand how cool this is.
