The Problem: Challenges in Web Accessibility

People with disabilities face various barriers to accessibility on the web, depending on their type and degree of impairment. Some of these barriers include:

• Navigation challenges: People with visual, motor, or cognitive disabilities may have difficulty navigating through websites that are not designed with keyboard support, clear structure, consistent layout, or meaningful labels. They may also struggle with websites that have complex or dynamic content, such as pop-ups, carousels, or animations.
• Comprehension challenges: People with auditory, visual, or cognitive disabilities may have difficulty comprehending websites that do not provide alternative formats or modalities for their content, such as captions, transcripts, audio descriptions, or text alternatives for images and videos. They may also struggle with websites that use unclear language, jargon, or abbreviations.
• Interaction challenges: People with speech, motor, or cognitive disabilities may have difficulty interacting with websites that do not provide accessible forms, controls, feedback, or error handling. They may also struggle with websites that require timed responses, complex gestures, or voice input

These challenges are not only frustrating and limiting for people with disabilities but also costly and detrimental for businesses and society. According to a report by The World Bank, people with disabilities represent about 15% of the world’s population and account for an estimated $8 trillion in annual disposable income. By excluding people with disabilities from accessing their websites, businesses are missing out on a large and valuable market segment. Moreover, by neglecting web accessibility standards and guidelines (such as WCAG 2), businesses are exposing themselves to legal risks and reputational damages

Therefore, there is an ongoing need for improvement in web accessibility, especially as online content grows and evolves. However, achieving web accessibility is not a trivial task. It requires a combination of technical skills, design principles, user testing, and quality assurance. It also requires constant monitoring and maintenance to ensure compliance and compatibility with changing technologies and user needs.

The Potential of AI in Web Accessibility

AI has the potential to overcome many of these challenges by automating or augmenting some of the tasks involved in creating and maintaining accessible websites. AI can also provide new ways of enhancing the user experience and inclusion of people with disabilities on the web.

Some of the forms of AI that can be applied to web accessibility include:
1. Machine learning: Machine learning is a branch of AI that enables computers to learn from data and improve their performance without explicit programming. Machine learning can be used to analyze large amounts of data and extract patterns, insights, or predictions that can help improve web accessibility. For example,

• Machine learning can be used to generate alternative text for images and videos based on their visual content or context.
• Machine learning can classify web pages according to their accessibility level or identify accessibility issues based on predefined criteria.
• Machine learning can be used to personalize web content or interfaces based on user preferences or needs.

2. Natural language processing: Natural language processing (NLP) is a branch of AI that enables computers to understand and generate natural language (such as text or speech). NLP can be used to process and produce accessible content or communication for people with disabilities. For instance:

• NLP can be used to provide captions or transcripts for audio or video content based on speech recognition or synthesis.
• NLP can be used to provide audio descriptions for visual content based on text summarization or generation.
• NLP can be used to provide voice or chat-based interaction for web users based on natural language understanding or generation.

3. Computer vision: Computer vision is a branch of AI that enables computers to perceive and interpret visual information (such as images or videos). Computer vision can be used to enhance the perception and comprehension of web content for people with disabilities. For example,

• Computer vision can be used to provide magnification, contrast, or color adjustment for web content based on image processing or enhancement.
• Computer vision can be used to provide facial recognition, emotion detection, or gesture recognition for web users based on image analysis or recognition.
• Computer vision can be used to provide object recognition, scene description, or navigation assistance for web users based on image understanding or generation.

Case Studies of AI Applications in Web Accessibility

There are already some examples of how AI is being used to improve web accessibility in various domains and contexts. Here are some of them:
