W3C WAI Inaccessibility of CAPTCHA Note Published

It’s with great pleasure I can share with you that after several years of work, the World Wide Web Consortium (W3C) Web Accessibility Initiative (WAI) Note that I’ve been involved in relating to the inaccessibility of CAPTCHA has been published. The purpose of this Note is to help developers understand the issues and implement accessible CAPTCHA solutions.

In a formal statement by Janina Sajka , the W3C WAI advised that:

Today the Accessible Platform Architectures (APA) Working Group, with the assistance of its Research Questions Task Force (RQTF), has published: “Inaccessibility of CAPTCHA,”  as a W3C Note:

http://www.w3.org/TR/turingtest

First published in 2005  today’s 2.0 publication extensively updates the earlier version to bring our analysis and recommendations up to date with CAPTCHA practice today.

CAPTCHA technologies covered in today’s publication include:

  • Traditional visual and audio CAPTCHA, including CAPTCHA games and logic puzzles as practiced today.
  • reCAPTCHA v2 and v3
  • Blinded verification tokens
  • Honeypots
  • Biometrics
  • Proof of WorkHeuristics, PKI certificates, and much more.

Today’s publication is the culmination of almost two years of extensive research, discussion, writing, and editing by APA’s Research Questions Task Force (RQTF). The document is extensively documented with references to research publications and numerous on line resources. Comments received in response to three separate wide public review draft publications aided our work immensely.”

As the lead editor for the Note, I’d like to take this opportunity to thank fellow editors Janina Sajka, Jason White and Michael Cooper for the opportunity to be involved with the update along with the many contributions provided by the general public during the feedback process.

For more information on CAPTCHA and its impact on people with disabilities, please refer to the excellent ABC article The internet thinks you’re a robot, and other ‘dark patterns’ people with disabilities face online.

Affordable Access resource receives a refresh

In my former role with Media Access Australia, I worked with VisAbility to project manage and write the contents of the Affordable Access resource. The resource was well received at the time and I was very excited when the Centre For Inclusive Design (CfID) invited me back to develop content for its recently launched refresh.

The original resource was funded by an Australian Communications Consumer Action Network (ACCAN) grant, focused on providing guidance on consumer-based technologies that are both affordable and contain accessibility features. As explained on the homepage of the resource:

“The Affordable Access initiative is all about providing equal access to technology for people with hearing, sight or cognitive issues or disabilities, that is both affordable and easy to use.

There are lots of great products on the market that contain accessibility features, yet it’s often hard to work out which ones are well suited and which options are best on a limited budget.

This resource has been created to help you make educated choices on options priced up to $250. You’ll find useful information on the specific accessibility features that are in popular devices such as tablets, smartphones, desktop computers, TV media players and assistive technologies that provide the best deals for the average user on a budget.

The options presented on this website include commonly used everyday products plus additional options for those who are more tech savvy.”

At the beginning of the year the CfID contacted me regarding their interest in wanting to update the website which was now several years out of date, and it was a great privilege to be asked to return to the project to support CfID in the refresh. With new content and a design overhaul, the resource again provides up-to-date information across what’s accessible, what’s available, what’s suitable and what’s possible.

Many thanks to CfID for the opportunity to be involved in updating the Affordable Access resource. The resource is located at www.affordableaccess.com.au.

Google Android 10 changes naming convention and improves logo for vision impaired users

The new version of Google Android is dropping its dessert-base naming convention and has updated the Android logo to improve accessibility.

Traditionally Google Android has featured a naming convention based on desserts and in alphabetical order in addition to its numerical name. Recent examples of Android operating systems include 7.0 Nougat, 8.0 Oreo and 9.0 Pie. However, for the next version Google has announce did will simply be called Android 10.

In addition, Google has launched a new Android logo that has been specifically designed with accessibility in mind. In a video outlining the change, it is stated that the updated Android logo features a “…new colour palette and visual identity system.”

The video highlights the change by stating “The core of Android is for everyone…accessibility has already been at the heart of Android recognition…we wanted to stay in the family of green but unless we use a really dark green, its hard for some people to see.”

 “So we developed a more robust accessibility palette…we now have all our communication accessible to all.”  

The logo change significantly improves the colour contrast, making it compatible with the 4.5:1 colour contrast ratio required by the W3C Web Content Accessibility Guidelines (WCAG) 2.1 Level AA standard.

Android 10 is currently available as a public beta with its formal release, along with the new logo, expected in the coming months.

Minecraft 1.14.0 Java edition adds accessibility menu and features

 Minecraft, the block-building computer game, remains one of the most popular video game titles of all time. Despite the game recently celebrating its 10th birthday, it continues to draw a crowd with an estimated 91 million active users continuing to enjoy the interaction with blocks, zombies and creepers as of March 2019. While the game already has a global following, it may see growth among disabled gamers due to recent improvements to the Java edition of the game.

In its recent 1.14.0 major update known as Village and Pillage the first bullet point states that there are “lots of accessibility improvements!” The Release Notes provide more specific detail, outlining the accessibity improvements as:

  • There’s a new Accessibility menu which provides a useful place for all of our accessibility features to be toggled
  • When the narrator is turned on, buttons will be narrated on focus
  • Most screens allow tab and shift+tab navigation through buttons, edit boxes and other UI elements
  • Most lists allow up/down arrow keys to navigate through them
  • We’ve added a new option for turning up the background of all transparent text elements, which should help make them more readable for some people

With the help of player SuperkidsST I was able to try out the use of Narrator in Windows 10 and could successfully move around the buttons and read out text. The other accessibility features appear to work well too. The inclusion of the new menu panel made it much easier to locate the features and quickly toggle between them.

Given the age of the Minecraft Java edition, it’s great to see Microsoft continuing to improve the accessibility of the game. Special thanks to SuperkidsST for helping me to see the accessibility features in action.
