What is Accessibility? A Comprehensive Definition for the Digital Era

In the IT industry, over 4.4 million software developers, tech enthusiasts, and everyday users rely on the power of accessible software and technology. Accessibility is the idea that everyone should be able to independently access and engage in digital and online content, no matter their ability or background. As the number of individuals requiring adapted technology grows, so does the need for accessibility in digital applications. This glossary page delves into every essential aspect of accessibility, from its definition and how it works to benefits, use cases, best practices, and recommended reads.

“The power of the Web is in its universality. Access by everyone regardless of disability is an essential aspect.” – Tim Berners-Lee

What is Accessibility? Definition of Accessibility

Accessibility refers to the design and development of software, technology, websites, and other digital products to ensure they are usable by people with diverse abilities. This includes individuals with visual, auditory, motor, and cognitive disabilities. By making technology accessible, developers strive to eliminate barriers and provide the same user experience for everyone.

ℹ️ Synonyms: Ease of use, Approachability, Availability, Readability, Usability, User-friendliness, Inclusivity, Adaptability, Openness, User accessibility.

How it Works

Accessibility is achieved through a combination of design principles, coding techniques, and user experience (UX) practices that prioritize the needs of all users. Developments in assistive technology, such as screen readers for the visually impaired, have propelled accessibility forward. Additionally, there are specific guidelines for web accessibility, known as the Web Content Accessibility Guidelines (WCAG), which offer a global standard for understanding what makes digital content accessible to users with different needs.

Benefits of using Accessibility

• Expanded audience reach: By designing accessible software, developers can reach a wider range of users, including the 15% of the world’s population with disabilities.
• Inclusive user experiences: Accessibility ensures that every user feels included, valued, and respected when interacting with digital products.
• Improved SEO: Search engines, such as Google, often prioritize accessible websites in search results, resulting in better search engine optimization (SEO) and increased visibility.
• Legal compliance: In many countries, accessibility is required by law, and non-compliant websites could face financial penalties or legal challenges.
• Increased usability for all users: Designing for accessibility generally improves the overall user experience by making interactions more simple, streamlined, and effective.

Accessibility use cases

Accessibility practices can be found in various digital applications, including:

Web content

Creating websites that follow WCAG guidelines ensures that users with visual, auditory, motor, or cognitive disabilities can navigate and engage with the content.

Mobile apps

Developing accessible mobile apps helps people with disabilities utilize essential smartphone services, such as making phone calls, sending messages, or using apps.

Software applications

Designing user interfaces that incorporate accessibility features, such as keyboard shortcuts or screen magnifiers, allows users with disabilities to effectively use software tools.

Video and audio content

Creating accessible multimedia content by including captions, transcripts, or audio descriptions helps people with hearing or visual impairments engage with the material.

Best Practices

When it comes to implementing accessibility, developers and designers should prioritize following WCAG guidelines, consider accessibility in all stages of development, and regularly test their software with diverse users and assistive technologies. Additionally, it is essential to stay current with advancements in accessibility research and continually strive to incorporate new techniques and strategies. Finally, foster a company culture that promotes and values inclusivity to ensure accessibility remains a top priority.
