Your Users Are Not Just Human: Designing Systems for People and LLMs
Tue, 21 April
Accessibility has often been treated as a usability feature or a compliance requirement, important but secondary. In AI-driven systems, that assumption no longer holds. Large language models consume and interpret the content we produce, and their effectiveness depends on structure, semantics, and clarity. When content is accessible, it becomes easier for both humans and machines to understand, process, and reuse.
This session reframes accessibility as a systems-level engineering concern rather than a design afterthought. It explains how accessible structure provides the signals machines rely on, why accessible content performs far better than OCR for AI-driven workflows, and how small, practical changes can improve machine readability, reduce processing costs, and lead to safer and more predictable outcomes.

Why accessible interfaces and documents outperform OCR for AI, automation, and data extraction
-
Practical ways to introduce accessibility into existing systems without rewriting them
