What is Digital Accessibility?
Digital accessibility applies to many types of information and communication technologies (ICT), including:
- Electronic Devices: Smartphones, computers, laptops, gaming consoles, virtual/augmented reality devices (AR/VR), home appliances, and more.
- Software Apps: Applications that run on common operating systems, such as Windows, Mac OS, iOS, and Android.
- Websites: Web content and portals that can be accessed through browsers, such as Google Chrome, Mozilla Firefox, and Microsoft Edge.
Why Digital Accessibility is Important in 2026
As digital services become increasingly integrated into everyday life, accessibility features are essential to make digital experiences inclusive and accessible for all users. Here are a few examples of how they improve the user experience for people with disabilities:
- People with low vision or colour blindness can read content more easily when websites use sufficient colour contrast and alt text descriptions that can be read by screen readers.
- Users with motor disabilities can navigate digital platforms more independently when websites support keyboard shortcuts, switch devices, and other assistive technology.
- People who are deaf or hard of hearing can understand video content through an alternative audio description, captions, or subtitles.
- Users with intellectual disabilities benefit from clear instructions, simple language, and consistent navigation.
Key Benefits of Digital Accessibility and Inclusivity
For instance, The Ascott Limited partnered with SG Enable to strengthen disability inclusion, including enhancing its digital platforms and creating more inclusive guest experiences. Explore some of the key benefits of implementing inclusive practices:
Expanding your market share
Digital accessibility allows organisations to reach a wider audience, including persons with disabilities, older adults, and users with different needs. By making digital products and services accessible, businesses can attract more customers and create opportunities to serve a broader market.
Enhancing your brand
Demonstrating a commitment to web accessibility strengthens an organisation’s reputation and shows that it values inclusion and social responsibility. Accessible experiences can build greater trust, loyalty, and positive perceptions among customers.
Increasing savings in the long-term

Learn MoreWhat Are the Steps to Create Accessible Digital Content, Products and Services?
There are many factors to consider when creating or designing a digital product or service that is accessible to everybody, including those with visual, hearing, physical, cognitive, or other disabilities. The following steps can help guide the development of accessible digital products and services.
Digitally Accessible Best Practices for Visual Impairment
People with visual impairments may have low vision, colour blindness, or be blind, and often use assistive technologies such as screen readers, screen magnifiers, or braille displays to access digital content. Designing with accessibility in mind ensures that information can be perceived and navigated regardless of how users interact with a screen.
- Provide descriptive alternative text (alt text) for images, icons, and other non-text content, so screen readers can convey their meaning.
- Use high-contrast text and backgrounds for readability, and add text, icons, or other visual cues to ensure everyone can understand the content.
- Structure content using semantic HTML elements (e.g. headings, lists, and form labels), and apply ARIA labels (accessibility attributes for HTML elements) where appropriate.
- Allow users to resize text or zoom in through built-in web accessibility functions without affecting content usability or readability.
Digitally Accessible Best Practices for Deaf / Hard-of-Hearing
People who are deaf or hard of hearing access digital content differently, with many relying on captions, transcripts, hearing aids, or visual cues instead of audio. Designing with these needs in mind ensures that important information is not conveyed through sound alone, allowing users to fully participate in digital experiences.
- Ensure all interactive elements can be activated using alternative input devices, such as adaptive switches, eye-tracking systems, or head-mounted pointers.
- Add captions or subtitles to the videos, webinars, and other multimedia content that contain spoken information.
- Provide transcripts for audio content such as podcasts and recorded announcements.
- Offer alternative communication channels, such as SMS, email, or live chat, instead of relying solely on phone calls.
- Avoid using audio-only alerts by pairing them with clear visual notifications or text.
Digitally Accessible Best Practices for Physical Disability
People with physical disabilities may have limited mobility or dexterity and use assistive technologies such as screen readers, keyboards, adaptive switches, eye-tracking devices, or head-mounted pointers to interact with digital products. Accessible design should support multiple ways to navigate and complete tasks without requiring precise mouse movements.
- Ensure all interactive elements can be activated using alternative input devices, such as adaptive switches, eye-tracking systems, or head-mounted pointers.
- Make buttons, links, and interactive elements large enough to select easily.
- Avoid complex interactions such as dragging or precise movements.
- Allow users enough time to complete forms and other time-sensitive tasks.
Digitally Accessible Best Practices for Intellectual Disability
People with intellectual disabilities may experience challenges with learning, memory, or processing information. Clear, predictable, and easy-to-understand digital experiences help reduce cognitive effort and enable users to complete tasks with greater confidence and independence.
- Use plain language and avoid jargon or unnecessarily complex sentences.
- Organise content using a clear and logical page structure.
- Provide clear instructions and helpful error messages when users complete forms.
- Allow sufficient time for users to read content and complete tasks such as payments or registrations.
Digitally Accessible Best Practices for Autism
Users with autism may experience sensory sensitivities or process information differently, making overly stimulating or ambiguous digital experiences difficult to use. Calm, consistent, and predictable interfaces can improve usability and help users focus on completing their tasks.
- Use simple, direct language and avoid idioms, sarcasm, or figurative expressions where clarity is important.
- Minimise bright colours, flashing elements, and excessive animations that may cause sensory overload.
- Maintain a consistent layout and navigation throughout the website or application.
- Give users control over moving or autoplaying content whenever possible.
WCAG: Key Principles of Digitally Inclusive Products/Services
The Web Content Accessibility Guidelines (WCAG) provide an internationally recognised framework for creating highly accessible digital products and services.
Developed by the Web Accessibility Initiative (WAI) of the World Wide Web Consortium (W3C) in consultation with accessibility experts, people with disabilities, and industry stakeholders, the WCAG design principles help ensure that the needs and experiences of people with disabilities are considered throughout the design and development of digital products and services.
4 Principles of WCAG: POUR
- Perceivable: Digital content and user interface elements should be presented in ways that users can perceive, regardless of their abilities.
- Operable: Users should be able to navigate and interact with digital products and services using different input methods, including keyboards and assistive technologies.
- Understandable: Information and user interfaces should be clear, consistent, and easy to understand.
- Robust: Digital content should be developed using standards that allow it to work reliably across different devices, browsers, and assistive technologies.
Applying WCAG
Applying the Web Content Accessibility Guidelines (WCAG) involves putting the four POUR principles into practice throughout the design, development, and maintenance of digital products and services.
Principle 1: Perceivable
Provide text alternatives for non-text content.
Example: Add alternative text (alt text) for images, icons, charts, and other visual elements.
Ensure multimedia content is accessible.
Example: Provide captions, transcripts, sign language interpretation, and audio descriptions where appropriate.
Present content in adaptable ways.
Example: Use clear headings, logical reading order, and meaningful page structure so content can be interpreted by assistive technologies.
Make content easy to distinguish.
Example: Use sufficient colour contrast, readable font sizes, and avoid relying on colour alone to convey information.
Principle 2: Operable
Ensure all functionality can be operated using a keyboard.
Example: Users should be able to navigate and interact with all content without relying on a mouse.
Provide enough time for users to complete tasks.
Example: Allow sufficient time for form submissions, provide warnings before session timeouts, and enable users to extend time limits where possible.
Avoid content that may trigger seizures or physical reactions.
Example: Do not use flashing, flickering, or rapidly moving animations.
Make navigation clear and intuitive.
Example: Ensure users can easily move through pages, locate information, and avoid getting stuck when using assistive technologies.
Support multiple input methods.
Example: Ensure compatibility with voice control, switch devices, and touch interfaces with sufficiently large tap targets.
Principle 3: Understandable
Use clear and readable content.
Example: Write in simple, direct language and avoid unnecessary jargon or complex terminology.
Ensure interactions are consistent and predictable.
Example: Maintain consistent navigation, layouts, and functionality across different pages so users know what to expect.
Help users prevent and correct errors.
Example: Provide clear instructions, identify errors in forms, and offer helpful suggestions to guide users in resolving them.
Principle 4: Robust
Ensure compatibility across devices and search engines.
Example: Develop and regularly test digital content to ensure it works reliably with different browsers, devices, and assistive technologies such as screen readers.
How to Identify Digital Accessibility Issues?
Identifying digital accessibility issues is an essential step in creating inclusive digital products and services. A comprehensive accessibility evaluation should combine automated testing, manual testing, and user testing.
Automated Testing
Automated testing is a useful first step in quickly and efficiently identifying common digital accessibility issues. Tools such as the WAVE Accessibility Evaluation Tool can automatically scan websites or applications for technical issues, including missing alternative text for images, unlabelled buttons, insufficient colour contrast, and autoplaying media.
Manual Testing
Manual testing complements automated testing by identifying accessibility issues that automated tools cannot detect. While tools like WAVE can help identify common accessibility barriers, they typically detect only around 20% to 30% of accessibility issues2. A manual review is therefore needed to assess the website or application from a user's perspective, ensuring that content is understandable, navigation is intuitive, and interactive elements function as expected.
Manual Testing Activities
Common manual testing activities include navigating a website using only a keyboard, checking that focus indicators are visible, verifying the reading order of content, assessing colour contrast and text readability, conducting a no-sound test, and ensuring forms, buttons, and links are clearly labelled and usable.
Screen Reader Testing Options
Screen reader testing helps verify whether digital content can be accessed and understood by users who are blind or have low vision. Common screen readers include NVDA and JAWS for Windows, VoiceOver for macOS and iOS, and TalkBack for Android. Testing with these tools can help identify issues with headings, image descriptions, form labels, and navigation.
How to Conduct Manual Testing
Manual testing involves three key stages to understand how real-world users experience and interact with a website or application, while identifying potential accessibility barriers.
Pre-testing: Begin by defining the areas and features to be tested, and prepare the necessary testing devices, assistive technologies, and test accounts required for the evaluation.
Testing: Conduct the planned test scenarios and record any accessibility issues encountered during the process. Document details such as the location of each issue, the steps taken to reproduce it, and supporting evidence such as screenshots or screen recordings.
Post-testing: Compile the findings into an accessibility testing report for future reference. The report should clearly describe identified issues and provide recommendations or suggested actions to address them.
Questions to Help Note Down Accessibility Requirements and Issues
When conducting manual testing, documenting accessibility issues clearly helps teams understand the impact of each barrier and determine how to address it. The following questions can guide testers when recording their findings:
How does this issue affect accessibility for users?
How and where did I encounter this issue?
What did I expect to happen?
What was the actual result, and how did it differ from my expectation?
What changes could be made to achieve a more accessible outcome?
Here is a sample accessibility testing report to demonstrate how it can help organise findings in a structured way:
| No. | Page Name/URL | Issue | Description | Screenshot File Names | Recommendation | WCAG Level |
|---|---|---|---|---|---|---|
| 1 | Homepage | Promotional banner has no alt text | The promotional banner on the homepage has no alt text description. For screen reader users, this means they will not know what the image is for or what its contents are. | 01. Home - Banner no alt text.jpg | If the image serves a specific function and is not considered purely decorative, provide an alt text description for the image. | 1.1.1 Non-text Content (Level A) |
