An example is a visually impaired student in Pune who wants to sign up for an online course using a popular ed-tech app but finds that there is no screen reader support or any visible button due to a low contrast ratio. Although she was provided with instructions for how to complete the registration form using the screen reader, she has no way to verify that any error messages (which are all in red) have appeared. Closed the app and never returned to it.
This is an example of something that occurs millions of times every day throughout websites, applications, and digital products that were built with no consideration given to assistive technology or accessibility. By 2026, the costs associated with failing to provide access to digital products will be higher than ever (ethically, legally, and financially).
The goal of UI design that is accessible to people with disabilities is to create digital interfaces that are usable by everyone, regardless of ability. Accessibility has gone from a concern that was once seen as a niche issue and a compliance box to tick off, to an indispensable part of UI design for inclusive brands; therefore, it is no longer a secondary consideration to having great brands or products, but rather a key differentiating factor between those two categories.
Understanding the Scope: Disability Is Not a Minority Issue
UI designers must first change their perception of disability as a fixed, unchanging, and minority issue towards one of disability as part of a wide-ranging or temporarily adverse impact associated with situational circumstances.
Microsoft’s Inclusive Design Framework offered designers a new way of understanding disabilities by illustrating how those with permanent mobility limitations require the same type of interaction (one-handed) as someone with temporary limitations (e.g., delivering a package while wearing two arms in restraints or holding an infant).
Examples demonstrating the successful and widespread application of universal design can be found within the user experience (UX) industry, where terminology that originally referred to features designed to assist people with disabilities is now common UX practice. Subtitles, which were initially used for the hearing-impaired, are now used by millions of commuters traveling on crowded buses or trains. Similarly, voice assistance applications were designed primarily for the physically challenged; however, this has evolved into a multi-billion-dollar industry. Finally, users in bright sunlight benefit from designing HCMs, which create a better experience for all users as compared to not using or enabling an HCM.
The four primary types of disabilities that UI designers must take into consideration when designing their user interfaces are:
Visual impairment – Needs to provide compatibility with a screen reader, sufficient contrast ratio, alternative text for images, and a method of providing information other than color-coded signals.
Auditory impairment – Needs to provide closed captions for video or audio content; transcripts for both; and a visual alternative for any audio alert signal.
Motor impairment – Needs to have large touch targets for screen interaction, compatibility with keyboard navigation, support voice control, and have no time constraints on performing actions in user interfaces; and
Cognitive impairment – Needs to use simple language with predictable navigation; have minimal distractions and refrain from using complex or technical language.
The Legal Landscape: The Law Is Catching Up – Fast
For many years, the majority of accessibility compliance in most markets was optional. That is changing, as countries worldwide begin to develop and enforce laws related to digital accessibility at an increasing rate, with penalties of some type being imposed on those companies that do not comply.
The ADA (Americans with Disabilities Act, established in 1990 and ongoing) has recently seen several court cases find that websites (and therefore their content) are “places of public accommodation,” making them potential liabilities under that law. At last count, there were over 4,600 lawsuits against companies for violating the ADA based on their website accessibility in a single year.
The EAA (European Accessibility Act), which will go into effect in June 2025, requires that all digital products and services being sold in the EU (including, but not limited to, e-commerce sites, banking applications, and e-readers) adhere to WCAG 2.1 AA standards. There will be heavy fines for companies that do not comply with those standards.
In the UK (Public Sector Bodies Accessibility Regulations), all public sector (government) websites and mobile apps must be compliant with WCAG 2.1 AA standards, and will undergo regular testing and publishing of accessibility status.
The Rights of Persons with Disabilities Act of 2016, RPWD Act, will ensure accessibility to Public Services and Government Digital Platforms for people with disabilities. The National Policy on Universal Electronic Accessibility recommends that Indian Websites comply with Web Content Accessibility Guidelines (WCAG). As the Indian digital economy continues to grow, it is expected that enforcement will continue to get much stricter.
For Startups and Digital Product Companies in India who want to export their products to Global Markets, such as the US and EU, making their products accessible is now a prerequisite for entering those markets.
The WCAG Framework: The Global Standard Explained
W3C maintains the WCAG (Web Content Accessibility Guidelines) as the global standard for how digital content can be made accessible to all users. WCAG 2.1 is the most recent version, and WCAG 2.2 has been finalised. WCAG 2.1 (AA) is the baseline threshold established in many laws.
W3C describes the four principles (POUR) of web accessibility:
- Perceptible – All information and user interface elements must be made available to the user in a manner that the user can perceive. No content should ever be invisible to any of the senses. Examples of this include providing an alternate text for images, captions for videos, and a sufficient contrast in colors between foreground text and background color.
- Operable – All user interface elements and all methods of navigation must be operable (able to be used) by the user. The user must be able to perform all functions using only the keyboard; if a function includes a time limit, the user must be able to either adjust the time limit or disable the time limit. No user interface element or method of navigation should require a specific physical ability in order for the user to be able to use it.
- Understandable – The information and operation of user interface elements must be understandable (able to be understood, or not confusing) to the user. The use of clear and simple language, predictable navigation, and constructive error messages (e.g., don’t just put a red box around invalid input) would contribute to increased understanding of the information.
- Robust – Content must be able to be used with current and future assistive technology (e.g., screen readers, switch access devices, Braille displays). This occurs when the code for the content is clean and semantically correct, with no potential to become unusable as technology evolves.
The Business Case: Why Accessibility Is Also a Business Strategy
The business case for accessible design is compelling and increasingly difficult for product teams and founders to ignore, as there is more than just legal compliance for businesses that create accessible designs!
Larger Addressable Market
There are 1.3 billion people with disabilities across the world, and growing due to the world population aging. Because of this, many potential users are locked out of most products due to inaccessibility. In India, there are more than 26 million people who have been registered as having a disability, but that does not account for those who will have situational and age-related impairments. People with disabilities, along with their families, represent approximately $13 trillion in annual disposable income around the world.
SEO and Discoverability Benefits
Accessible websites/applications have a much better chance of ranking highly on search engines due to many of the best practices (descriptive ALT tags, semantic HTML structure/standardized link labels, fast load time, etc.) laid out in WCAG overlapping with best practices for SEO. Because search engines and screen reader technologies require clean and structured markup to create a meaningful presentation of content, the work you put into making sites accessible to the user will also be the work that you will do to improve the SEO of that same site! You will have accomplished both goals at the same time!
Trust and Reputation
Brands that put inclusion first will earn the loyalty of consumers, especially younger generations, in a world where customers choose to buy based on their values. On the other hand, accessibility failings can go viral and cause significant damage to a brand’s reputation. A new application that actively advocates for access is a key differentiator in an increasingly competitive marketplace.
Cost Savings Over Time
The most expensive accessibility fix is the one you do after launch. Retrofitting access into an existing product is significantly more expensive than incorporating it in the first place (redesigning systems, redeveloping navigation flows, rebuilding codebases). Businesses that incorporate access from the beginning of their design processes consistently report lower costs of remediation in the long term.
Practical Implementation: How to Start Building Accessible UI Today
As a whole, the idea of making everything accessible can seem complex; however, creating even minor, systematic adjustments can greatly improve it in a practical sense. Below are the top actionable items for product designers and developers.
- Evaluate the Contrast of Your Colouration
Use colour contrast analysers like Colour Contrast Analyser or Figma plugins like Stark to verify that normal text adheres to the 4.5:1 ratio per WCAG, and large text adheres to the 3:1 ratio. With this one simple fix, a person with low vision and/or colour sensitivity will be able to use your product significantly better, and it won’t cost you a penny.
- Design for Keyboard Access First
Every single one of the interactions on your interface (forms, modals, dropdowns, carousels) should be available to the user regardless of whether they are using a mouse or not (using the Tab key, Enter key, arrow keys, and Escape key for navigation through the interface). Unplugging your mouse to test the product before it gets into your users’ hands is the only way to truly ensure that people with motor function disabilities will be able to access all parts of your product.
- Ensure That All Images Have Descriptive Alt Text
All non-decorative images must have alt text describing the image’s function in the context of the image’s purpose rather than simply describing what the image looks like. For decorative images, the alt text should be set to nothing so that screen readers do not read them.
- Use ARIA with Semantic Markup
Some HTML tags have a semantic meaning (button, header, main, nav, section) that automatically provide an indication of structure to assistive technologies through markup, but when not enough (using non-semantic markup), you can augment them by defining ARIA attributes to suit your needs, but also use them sparingly.
- Provide Properly Accessible Error Indications
Never use colour by itself to convey error indications; combine colours with text indication(s), image or icon indications or both. Error messages should be displayed in proximity to the control they relate to and associate the message back to the control programmatically.
- Provide Captions for All Audio & Video Content
While auto-generated captions provide some value, they require review for accuracy by a human editor to ensure that correct phrasing and context are used; furthermore, captions should reflect verbatim text of spoken dialogue as well as other relevant sound effects and affordances so that a reader will have a better understanding of the presentation’s visual aspects. Also, all audio-only presentations should be accompanied by transcripts.
- Conduct Testing for Actual Users of Assistive Technology
Use NVDA or VoiceOver (both free screen readers), perform zooming operations to check for layout failure at 200%, and also do user testing with actual people who use/require assistive technology. Approximately 30-40% of accessibility issues can be detected through automated means; the remainder must be found through user testing.
Conclusion
Accessibility should not be treated as a mere feature, compliance check, or sprint backlog; rather, it is a fundamental criterion for design and as important to good UI design as visual hierarchy, usability, and performance.
The legal environment is changing quickly, and all organizations with an ‘afterthought’ attitude to accessibility are increasing their risk with each product update. However, in addition to compliance, it is much simpler than that: good design includes everyone in the user group. By designing for all types of human ability (permanent/temporary/situational), you create products that are going to be easier to use, measured as more trustworthy, and ultimately more successful for all users.
For designers and developers in India developing for the global market in the present time, this is the moment to include inclusive design in their primary level of competency. All the tools are available, and the frameworks are straightforward; therefore, there is an undoubted business case. The only question remaining is, do you design for everyone, or just some?
