Accessibility in design ensures that digital products and services can be used by everyone, including people with disabilities. It’s not just a matter of social responsibility, but also a legal requirement in many jurisdictions. Ensuring inclusivity means that a broader audience can use, understand, and benefit from digital content.
- DefinitionThe WCAG is a set of guidelines developed by the Web Accessibility Initiative of the World Wide Web Consortium (W3C). It offers a framework for making web content more accessible to people with disabilities.
- PrinciplesThe WCAG is built on four foundational principles, often referred to by the acronym “POUR”:
- Perceivable: Information and interface components must be presentable in ways that users can perceive. This includes providing text alternatives for non-text content and ensuring content is adaptable.
- OperableInterface components and navigation must be operable, ensuring functionalities are available from a keyboard, giving users enough time to read and use content, and avoiding content that can cause seizures.
- UnderstandableInformation and operation of the interface must be understandable. This includes making text readable and predictable and ensuring websites operate in consistent ways.
- RobustContent must be robust enough to be reliably interpreted by a wide variety of user agents, including assistive technologies.
- Diverse User PersonasWhen creating user personas in the design process, include personas with disabilities to ensure the design process accounts for varied needs.
- Color and ContrastEnsure there’s sufficient contrast between text and background colors. Avoid using color as the only way to convey information, as this can be problematic for color-blind users.
- Keyboard NavigationDesign so that all functionalities can be accessed using a keyboard alone, benefiting those who can’t use a mouse or touch screen.
- Alternative TextProvide alternative text for images, videos, and other non-text content, ensuring screen readers can convey the content’s meaning to visually impaired users.
- Captions and TranscriptsVideos should include captions for those with hearing impairments. Transcripts can also help provide a text version of audio content.
- Avoid Flashing ContentFlashing or flickering content can trigger seizures in users with photosensitive epilepsy.
- Consistent NavigationMaintain consistent navigation and layout throughout the website, aiding users with cognitive disabilities by providing a predictable experience.
- Accessible FormsLabel form fields explicitly, provide error messages that guide users in rectifying mistakes, and ensure all form controls are accessible via keyboard.
Conclusion: Accessibility is an integral aspect of modern digital design. By adhering to standards like WCAG and emphasizing inclusivity, designers can ensure that their products are usable by the widest possible audience, including those with disabilities. A more accessible design not only enhances the user base but also promotes equity and inclusiveness in the digital realm.
Key terms in plain language
Open a term for a concise explanation of language used on this page.
Artificial Intelligence (AI)
Software designed to perform tasks involving prediction, classification, generation, reasoning, or decision support. Business use still requires clear data, governance, security, and human accountability.
API
An application programming interface is a defined way for software systems to exchange data or request functions from one another.
Cloud Computing
Computing resources—such as applications, servers, storage, or databases—delivered from remote infrastructure and scaled as requirements change.
Cybersecurity
The practices and controls used to protect identities, devices, networks, applications, and data from unauthorized access, disruption, or manipulation.
Identity and Access Management (IAM)
The systems and policies that determine who a user is, what resources they may access, and how that access is authenticated and reviewed.
Bandwidth
The amount of data a connection can carry in a given time, usually measured in Mbps or Gbps. More bandwidth supports more users, devices, and simultaneous applications.
