Principles Of Digital Accessibility

By CIOReview | Saturday, May 7, 2022

Due to the pandemic, many individuals, including those with disabilities, now count on digital products and services for work, shopping, banking, entertainment, and healthcare.

FREMONT, CA: Digital accessibility is making digital products accessible to all users, such as websites, mobile apps, and other online tools. It is about ensuring that all users, regardless of their disabilities, have equal access to the same information.

Whether a visually impaired person uses a screen reader to access a website or a person with a cognitive handicap requires straightforward content and navigation, there are numerous reasons to make digital presence accessible.

The WCAG establishes four web accessibility principles—dubbed POUR—that serve as the foundation for material created for the online and for everyone who wants to utilize the web:


The user interface's information and features must be displayed so that the senses can perceive them so that nothing is undetectable or invisible. While web usability is determined mainly by visual signals, those who cannot perceive visual cues rely on sound and touch.


The interface's interactive features, such as controls, buttons, and navigation, should be physically operated by clicking, touching, swiping, and rolling. Alternatively, voice commands should be available, as should other assistance devices such as head wands and eye trackers.


Technology should be presented and used unambiguously and consistently, with predictable patterns of use and design. The end-user should comprehend the meaning and purpose of the information offered in the content and the interface's user flow and interaction.


Content must be robust to function successfully across various technologies, including assistive devices.

If any of these four criteria are violated, the web will become inaccessible to individuals with impairments.

The necessity of digital accessibility for businesses

With over 20 percent of the population living with a disability, organizations worldwide have made web accessibility a priority.

However, digital accessibility is not limited to the ease with which persons with impairments can use websites.

While 71 percent of web users with disabilities will abandon an inaccessible website, visitors without impairments will also benefit from accessibility features.

All the visitors gain when companies maintain an accessible internet presence.

Enhance the user experience

A digital presence that is accessible ensures that users of all abilities can use the website as intended. Accessibility best practices help all users by paying specific attention to navigation, simplicity of use, and text clarity.

Increased revenue from sales

If digital content is not available to all, companies may unknowingly be excluded from up to 1.3 billion prospective customers. When it comes to spending on digital accessibility changes, it is usually asserted that ROI is difficult to quantify. However, accessible designs have several advantages that ultimately result in increased sales, including growing customer base by including the disabled, facilitating everyone's use of the site, facilitating mobile access, enhancing SEO rankings, and encouraging creativity.

The W3C publishes case studies of Fortune 100 organizations, including Apple and Barclays, that have benefited from an accessible design by improving search results, lowering maintenance costs, and expanding their audience reach.
