WAVE now available in Spanish

Friday, May 29, 2009

WebAIM recently announced that their free web accessibility evaluation tool WAVE is now available in Spanish. It's a great tool for testing web sites, and there's even a Firefox toolbar plugin!

WebAIM plans to translate the utility to more languages possibly Portuguese, German, Japanese, Thai, Turkish, and Russian. They are seeking volunteers to help; if you are interested, please contact WebAIM.

By the way, you can read a recent interview with Jared Smith of WebAIM from totallyaccessible.com.

CAPTCHA Alternatives and Articles

Tuesday, May 26, 2009

Seems like there's been more talk about CAPTCHA lately (stands for "Completely Automated Public Turing test to tell Computers and Humans Apart"). Most of us dislike the use of CAPTCHA in web forms. And all of us (I hope) can certainly agree that it's poor in usability, and often times not accessible--even for any human user; see Top 10 Worst Captchas. Even so, it's still way too common on the web. Damn spammers are forcing developers to implement this poor technique.

Fortunately, the collective intelligence of developers across the world have created many alternatives to CAPTCHA. Here are some great ideas from WebAIM's article Spam-free accessible forms:

• Detect spam-like content within submitted form elements.
• Detect content within a hidden form element.
• Validate the submitted form values.
• Search for the same content in multiple form elements.
• Generate dynamic content to ensure the form is submitted within a specific time window or by the same user.
• Create a multi-stage form or form verification page.
• Ensure the form is posted from your server.

Here are some other articles about the (in)accessibility of CAPTCHA and other resolutions:

• CAPTCHA GOTCHA
• CAPTCHAs, CAPTCHAs everywhere
• Inaccessibility of CAPTCHA (W3C)
• Accessibility of CAPTCHA (Juicy Studio)
• CAPTCHA Killer
• Web Axe podcast on CAPTCHA

Example of impossible CAPTCHA:

Video: Importance of HTML Headings for Accessibility

Wednesday, May 13, 2009

In the YouTube video Importance of HTML Headings for Accessibility, the user "gringochapin" (who is blind) demonstrates browsing a web page by its headings using a screen reader (JAWS). He demos a few different pages including a good and poor example. This is an excellent example of how proper headings is important for web accessibility. Ironically, there are no captions for this video.

Great slide deck on Slideshare. In addition to HTML, CSS, and JavaScript, Dirk Ginader adds "CSS for JavaScript" and ARIA.

Is Your Web Site Accessible?
Great questions a web designer and developer should continually ask oneself.

Adobe encourages the European commission to use WCAG 2.0
Boring, but important.

7 tips for designing for older users

Monday, May 04, 2009

Although the article from webcredible is titled "7 tips for designing for older users", the strategies are great for plain old usability and accessibility. Here is a summary with some comments.

1. Make obvious what's clickable and what's not. (Please don't mess with the underlines!)
   
2. Use radio buttons rather than dropdown menus. (Unless you have over, say, 8 options.)
   
3. Stay in one window.
4. Implement the shallowest possible information hierarchy. (And forget 3 or 4-level cascading menus; they are also difficult to navigation with our without a mouse.)
   
5. Include a site map and link to it from every page. (Also good for SEO.)
   
6. Keep your language simple.
7. Appear trustworthy.
