Accessible AI-Powered Chatbots

Screen Reader and Keyboard Accessibility

1. Prevent the screen reader focus from jumping to the top of the page after users send a response in the chat window. Make sure the focus remains at the right location within the chat to avoid forcing users to manually navigate back. Additionally, test compatibility with screen readers’ jump-to-bottom commands to help users avoid frustrations during long interactions.
2. Ensure the main website content is not active or "bleeding through" while the chatbot is open. Focus should remain exclusively on the chatbot until the user exits the conversation.
3. All buttons and links should be labeled clearly so users can understand their purpose.
4. Create straightforward navigation to minimize confusion for users relying on assistive technologies.
5. Active or focusable elements must have sufficient color contrast to make them easily identifiable.
6. Notifications should clearly announce the arrival of new messages through both sound and visual cues. For users who are hard of hearing, use noticeable color changes or visual indicators. For blind or low-vision users, incorporate distinct alert sounds.
7. Provide detailed alt text for non-text elements like icons or images to ensure accessibility.
8. Avoid overusing emojis, as screen readers read out their descriptions, which can confuse users and disrupt comprehension.

Content Accessibility

1. Invest time and resources to ensure that all chatbot-generated content is reviewed by legal professionals to maintain accuracy and relevance. Relying solely on AI without human oversight can lead to misinformation.
2. AI systems often perpetuate unconscious biases, including those against people with disabilities. Developers should actively audit AI training datasets and logic to identify and mitigate biases.
3. Write chatbot responses in plain language and ensure they are legible. Avoid jargon, use appropriate font sizes, and provide contrast to accommodate users with visual impairments. Also, provide concise summaries of long or complex content to make information more digestible and accessible for users.
4. Offer more than just a phone number for additional help. Include an email address or online form prominently displayed on your site for accessibility.
