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


We’re Not Talking About Wheelchairs with Lasers


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.”


How to Learn To Be a Major League Baseball Player

1. Start easy2. Gradually build skill over time3. Learn to see patterns and know how to react4. Reactions become intuitive and natural5. Practice


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


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


This is What WCAG 2 Looks Like


This is What They Want


Make a Game Everyone Can Play

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


Level 4

• Missing alternative text• Unlabeled form element• No keyboard event for an equivalent mouse

event


Level 3

• A form control has more than one label• Page auto refreshes• No skip to main content link


Level 2

• Spacer image does not have an alt attribute• Pages have unique titles and don’t say

“Untitled Document”


Level 1

• Invalid code• Heading levels are skipped• No titles for frames


Level 0

• No alternative content for iframes


Demonstrate System

• http://accessibility.oit.ncsu.edu/accessibility-scan/

When Do People Use The System?

• Available 24/7 year round• Contests– NC State Global Accessibility Awareness Day

Website Challenge (April-May)– NC State World Usability Day Website Challenge

(October-November)


The Sales Pitch

“You have 28,000 accessibility errors across 8000 pages. Your site ranks 371 out of 385. You are in the bottom 10% of all categories. Can you fix these in the next 2 weeks? Oh, and you’ve had these problems for the past 2 years.”


The Results

• Corrected 27,500 errors• 40 out of 385• Top 5% in all categories

“I’m co-opting your employees for my own agenda”

Being a Good Gamemaster

• You can always make your game better– More frequent scanning– Historical rankings– Graphical and contextual view (WAVE)


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


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


The Limits of Gaming

• Automated scans only get you so far– Cannot test for everything


Automated Tests are Only So Good

The ALT text of this image mentions a color, 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
