What is FAST?

Todd Libby - 6 April, 2023 Devnexus

The Framework for Accessible Specification of Technologies (FAST) advises creators of technical specifications how to ensure their technology meets the needs of people with disabilities.

Todd Libby - 6 April, 2023 Devnexus

FAST was originally designed for internal accessibility spec review at the W3C.

Todd Libby - 6 April, 2023 Devnexus

Goals of FAST

Todd Libby - 6 April, 2023 Devnexus

Fill gaps in authoring tools where there are varying levels of accessibility.

Todd Libby - 6 April, 2023 Devnexus

FAST is intended to be a single, optional, well-considered, potential source of guidelines addressing specifically the features technologies need to provide to support accessibility.

User & Functional Needs

Todd Libby - 6 April, 2023 Devnexus

User need: A high-level accessibility characteristic of content and/or a user interface that is necessary for users to complete an objective.

Todd Libby - 6 April, 2023 Devnexus

Functional need: A statement that describes a specific gap in one’s ability, or a specific mismatch between ability and the designed environment or context.

Todd Libby - 6 April, 2023 Devnexus

Along with POUR (Perceivable, Operable, Understandabale, Robust) we have added Personalization and Deceptive Patterns with over 1,500 intersections of user and functional needs.

Todd Libby - 6 April, 2023 Devnexus

3 Stages of FAST

Todd Libby - 6 April, 2023 Devnexus

FAST Approach Three stages

• Inventory functional and user needs; • Identify ways to meet needs; • Develop technology guidelines to meet those needs as best as we can.

White/Light - Purity, good, innocence, cleanliness

• Primary/Secondary • Ethical/Non-Ethical Hacker • Deny/Allow-list • Exempt

Harry Brignull Cognitive Scientist, designer, UX consultant

• 2010 coined “dark patterns” • Gained traction in legal circles • Still used widely today • Deceptive practices go back as far as 1938!

A voting card in 1938 for Germans to vote for Adolf Hitler where the circle for “yes” is large and in the bottom center of the card with the “no” circle off to the right and smaller to separate those and identify those who voted against Hitler

Harry Brignull to Todd Libby

“Also I considered your words about “dark” patterns (and input from others) and I’m in the process of updating the site to use the term “deceptive patterns”. Also my new book will not use the term “dark patterns” as the title.

Deceptive Patterns or Anti-patterns

Todd Libby - 6 April, 2023 Devnexus

“A deceptive pattern is a deliberate anti-pattern designed to confuse or deceive a user. There is a difference between poor design and unintentional blockers for users.” Functional Needs Subgroup

Todd Libby - 6 April, 2023 Devnexus

“A deceptive pattern is where there is a deliberate attempt to aim or force a user down a particular path or to trap attention in a way that redirects or focuses on a goal, that the user either doesn’t want or need or maybe harmful to them.” Functional Needs Subgroup

Todd Libby - 6 April, 2023 Devnexus

Deceptive Pattern: Deliberate. With intent Anti-pattern: No intent but harmful/bad UX

Solving User Needs

Todd Libby - 6 April, 2023 Devnexus

Makes Web pages more accessible and usable, less harmful to people with disabilities and neurodivergent users, and creates friendlier and safer user experiences for everyone.

Barriers & Categories

Deceptive Patterns Examples of patterns/anti-patterns

• Trick questions; • Infinite scroll; • Copy and paste is disabled; • Timers; • Asking the user to enable features (microphone, camera, etc.).

Any current gap in the WCAG guidelines we want to address through FAST and Deceptive Patterns.

Todd Libby - 6 April, 2023 Devnexus

The most important part about bringing Deceptive Patterns to WAI / WCAG 3 is to reduce harm to those who are affected.

Todd Libby - 6 April, 2023 Devnexus

People can use without physical harm or risk (to themselves or others within a physical environment).

Ways to Meet User Needs

Todd Libby - 6 April, 2023 Devnexus

How to meet user needs:

• Author design & technical implementation • User agent accessibility support of standard & author-implemented features • Assistive technology support (including accessibility API mediation)

Todd Libby - 6 April, 2023 Devnexus

User needs need to be analyzed for how they can be met.

But…

What about large companies like Meta, Twitter, Google, etc.? How will you get them to change?
