Gamification
• Gamification [n]: the use of game design
elements in non-game contexts

Accessibility is Not a Game
• It’s a human right
• It’s should just be part of their job
• People might get addicted to the game

I Never Set Out To Make A Game
• Guiding Principles
– It takes practice to become an accessible Web
developer
– I am competing in a marketplace for people's
attention

Aristotle
• “If you want to become a major league
baseball player, you cannot simply wake up
one day and declare your self a baseball
player, capable of hitting a curve ball. You
must become habituated in the ways of being
a baseball player through a lifetime of
practice.”

Baseball Player

Start easy
Gradually build skill over time
Learn to see patterns and know how to react

Competing in a Marketplace of
Demands
• Prioritizations
– “Keeping the lights on”
• Production services to run and maintain
– Security and Compliance
• This impacts everyone, not just a “small number of
users”
• As important as you think you are, you’re not
seen that way by your campus/organization
@gdkraus
go.ncsu.edu/csun-2014
Gaming Principles
• A good game…
– Lets everyone play, regardless of skill level
– Lets you improve skills over time
– Gives you instant feedback

Accessibility is Not Fun
• But…
– Solving a problem is fun
– Seeing how you have improved and grown is fun
– Admit it … winning is fun

Prioritization
• 4 = fatal error, user cannot interact at all with
the element
• 3 = significant error, user can only partially
recover or it causes a significant hardship
• 2 = significant error, but user can usually
mostly, if not fully recover
• 1 = minor annoyance
• 0 = usually can ignore
@gdkraus
go.ncsu.edu/csun-2014
Level 4
• Missing alternative text
• Unlabeled form element
• No keyboard event for an equivalent mouse
event
@gdkraus
go.ncsu.edu/csun-2014
Level 3
• A form control has more than one label
• Page auto refreshes
• No skip to main content link
@gdkraus
go.ncsu.edu/csun-2014
Level 2
• Spacer image does not have an alt attribute
• Pages have unique titles and don’t say
“Untitled Document”
@gdkraus
go.ncsu.edu/csun-2014
Level 1
• Invalid code
• Heading levels are skipped
• No titles for frames
@gdkraus
go.ncsu.edu/csun-2014
Level 0

Being a Good Gamemaster
• You can always make your game better
– More frequent scanning
– Historical rankings
– Graphical and contextual view (WAVE)
@gdkraus
go.ncsu.edu/csun-2014
Tools and Resources Developed
• Web Accessibility Handbook
– go.ncsu.edu/accessibility-handbook
• Readability Bookmarklet
– go.ncsu.edu/readability
• Color Contrast Analyzer for Chrome
– go.ncsu.edu/color-contrast-chrome
@gdkraus
go.ncsu.edu/csun-2014
Key Elements That Make This Work
• Anonymity, to a degree
• Doing part of the work for them
– Setting up the scanner?
– Doing the scan for them?
• Giving guidance on what is important
• Giving immediate feedback on how to fix it
@gdkraus
go.ncsu.edu/csun-2014
The Limits of Gaming
• Automated scans only get you so far
– Cannot test for everything
@gdkraus
go.ncsu.edu/csun-2014
Automated Tests are Only So Good
The ALT text of this

which isn't useful for
blind users.

Future Developments
• Receive bonus points for performing manual
checks
• Get points for both
– Testing if the onscreen focus is always visible
– Fixing the onscreen focus problem if it exists
• Artificial intelligence techniques
– Determine if you have an appropriate number of
headings
