The second session offered by Accessibility Summit 2011, was about website accessibility. The presenter was Jared W. Smith (@Jared_w_smith). Check out his site at webaim.org.
Here are the notes about this session:
- Accessibility is process that is continuous - always can do more
- If your site is accessible, your not being innovative or updating your site enough!
- Provide a good experience for your users and readers of your site
- Accessible site certification - http://webaim.org/services/certification/
- WCAG 2.0 - principles, guidelines (ex. keyboard accessible), success criteria
- compliance does not equal accessibility - use as a set of guidelines
- Your site can be fully compliant with the guideline, but can still be functionally inaccessible
- WCAG 2.0 - great guidelines for web accessibility - http://www.w3.org/WAI/intro/wcag
Rule 1 - Equivalent alternative text
- can’t measure equivalence with a formula or tool
- does not mean exactly equal, does mean about the same or similar text
Rule 2 - Bypass Blocks
- bypass blocks of content that are replicated on several or multiple web pages
- test this out by: navigate with keyboard or listen to it in a screen reader
- "Skip to main content" links are useful and helpful, because browsers have yet to provide better keyboard navigation for users or readers who are sighted
- use common sense when using a text and background (use sensible contrast with colors)
Solutions to help with web accessibility:
- Learn about AT
- Learn about individuals with disabilities who utilize the web
- Use but do not rely on automated tools - WAVE - http://wave.webaim.org/
- Focus on the user’s experience
- Plan for progress
- become an accessibility champion - advocate for accessibility
- use common sense and guidelines
- prioritize the failures or the needs of improvement - what has the most impact on the user?
- Web pages need to be readable and functional when text is re-sized to 200%
- Images of text - text is used to give information rather than images.
- Test your site with a screen reader to avoid “screen reader freak out”

Accessibility Summit 2011
Session 1 - Color for the Colorblind
I attended the Accessibility Summit 2011 at Penn State University. The first session was presented by David Berman (follow on Twitter @DavidBerman) He presented about colorblindness and designing interfaces and websites. To learn more about the Accessibility summit go here, or follow it on twitter #a11ysummit. Here are my notes on the presentation by David Berman:
- Colorblind = life or death (traffic lights example - new test lights - two rectangular stop lights and one round green light )
- Most colorblind can see colors. But what they see isn't the same as what the non-colorblind see (depends on type).
- 10% of men have a color deficiency.
- Accessibility is about individuals with disabilities and also about the digital divide
- digital haves and have not’s
- many people have their first Internet experience on a cell phone!
- 4 reasons why accessibility is important:
- large percentage of users
- large labor pool
- it's the right thing to do
- legality compliance
- History of AT - designing for extremes (eg. hearing aids) helps everyone (ie end up in the development of the radio)
- Innovation for disability solution for the census and revolutionizes all of us!
- Disabilities can be divided into 4 groups
- permanent - blind birth
- temporary - broken arm
- acquired - age, tbi
- societal - left handed
- Impaired senses:
- visual
- mobility
- hearing
- language/communication - learning language, access to language, literacy,
- cognitive
- social
- There is a solution for these impaired senses - AT!
- Read regular - type face created for individuals who have dyslexia
- Rotating a d to a b, changes the whole meaning of the letter d. What an incentive to design better typefaces
- email was created as AT for a hearing deficit - a tech to type messages back and forth - how cool
- Nouse - scans head movements and eye blinks! - in 2 years a part of the pad and tablet technologies!
- Ideal accessibility web site : everyone, anytime, any connection speed
- WCAG 2.0 conformity levels ranging from A to AAA- most sites are AA compliant. Also section 508 compliant - in order to ensure that your site is accessible for individuals who have disabilities.
- We need to plan for accessibility
- When creating a site look out for:
Don’t rely on one sense to relay information to readers
Avoid poor contrast effects and colors (background and text)
snook.ca - can remedy contrast effects and colors
first steps to accessible PDF’s
provide text to speech (voki, avatars) to read text aloud
provide text to be adapted - larger/smaller text modifications
color background and text modifications available
larger landing zone for website selections (click here)
Use larger landing/click zones for clickable links
