Ain’t language funsies?

Accessibility Gets No Respect
“Cyberspace” (gray)
“Lime Rickey” (green)
“Online” (blue)
In fairness, Sherwin-Williams needs to come up with a lot of color names...

My Hierarchy for Motivating
Accessibility Change

17.
Getting Older
• Affects (nearly) everyone,
• Carries risks and side effects,
• Is not for the young.
I’m still experimenting with it.

Tech Support
• Think of your family!

This is why we hate the holidays.

The Message

User Stories
• Components:
• User,
• Outcome,
• Value.
• Writing:
• As user, I want outcome.
• As user, I want outcome so that value.
• In order to get value as user, I want outcome.
How to Write User Stories for Web Accessibility

51.
Selfish User Stories
• As a user on a sun-lit patio, I want to be able
to read the content and see the controls.
Add beer and as a user I may have trouble focusing.

52.
Selfish User Stories
• As a user in bed with a sleeping spouse, I want
to watch a training video in silence so that I
can get caught up at work.
As a user who doesn’t want to get punched for having slacked off at work.

53.
Selfish User Stories
• In order to click links as a user with no elbow
room in coach class with a tiny trackpad, I
want click areas to be large enough and
adequately spaced.
As a user in coach class who also paid too much for the drink he’s spilling on his keyboard.

54.
Selfish User Stories
• As a user distracted by the TV, I want clear
headings and labels so that I don’t lose my
place.
As a user who really should be finishing his work in the office.

55.
User Stories
• Physical Impairment
• As a keyboard-only user, I want to be able to use
the entire application.
This includes seeing what has focus and not getting lost in off-screen elements.

56.
User Stories
• Physical Impairment
• As a keyboard-only user, I want to be able to use
the entire application.
• As a keyboard-only user, I want to navigate a
product list with the tab key so that I can find the
right option.
Arrow keys are acceptable as well, making sure that it is clear to the user.

57.
User Stories
• Physical Impairment
• As a keyboard-only user, I want to be able to use
the entire application.
• As a keyboard-only user, I want to navigate a
product list with the tab key so that I can find the
right option.
• In order to click links as a limited-mobility user, I
want click areas to be large enough and
adequately spaced.
Else I may click the wrong item and have to hit the back button, which can be time consuming.

58.
User Stories
• Visual Impairment
• As a color blind user, I want to be able to see links
in page content.
Underlines are important, but users also like to know what they clicked already.

59.
User Stories
• Visual Impairment
• As a color blind user, I want to be able to see links
in page content.
• As a low-vision user, I want to zoom the page so
that I can read the content.
Without the text overlapping itself or every other item on the page.

60.
User Stories
• Visual Impairment
• As a color blind user, I want to be able to see links
in page content.
• As a low-vision user, I want to zoom the page so
that I can read the content.
• In order to use the site as a blind user, I want to
use a screen reader to navigate.
Good headings, clear structure, landmark roles to jump around the page.

61.
User Stories
• Hearing Impairment
• As a low-hearing user, I want to be able to access
transcripts.
From a clear link, not through some acrobatics to find them.

62.
User Stories
• Hearing Impairment
• As a low-hearing user, I want to be able to access
transcripts.
• As a low-hearing user, I want access to closed
captions so that I can use training videos.
Timed to match the video is important.

63.
User Stories
• Hearing Impairment
• As a low-hearing user, I want to be able to access
transcripts.
• As a low-hearing user, I want access to closed
captions so that I can use training videos.
• In order to participate in a webinar as a deaf user,
I want real-time captioning or transcripts.
This can be tricky, since you’ll need to have a resource typing in real-time.

64.
User Stories
• Cognitive Impairment
• As a user with a vestibular disorder, I want to be
able to disable parallax scrolling.
But you don’t just use it for no reason, right?

65.
User Stories
• Cognitive Impairment
• As a user with a vestibular disorder, I want to be
able to disable parallax scrolling.
• As a user with dyscalculia, I want distinct number
fields for each block of digits in a credit card
number so that I can purchase a product.
You can auto-detect card type. Do the same for expiration date.

66.
User Stories
• Cognitive Impairment
• As a user with a vestibular disorder, I want to be
able to disable parallax scrolling.
• As a user with dyscalculia, I want distinct number
fields for each block of digits in a credit card
number so that I can purchase a product.
• In order to not get confused on pages with long
text passages as a user with dyslexia, I want
control over text size, spacing, and/or alignment.
At the very least, turn of justified text.
