Introduction: Driving HCAI Forward

The central ideas of this book are the HCAI framework, design metaphors, and governance structures. These ideas clarify how human-centered thinking will help bring the powerful AI algorithms into widespread use by way of reliable, safe, and trustworthy systems. AI’s expansion from a focus on algorithms to include user experience design methods is happening in practitioner and research communities, which now regularly discuss ethics, responsible AI, fairness, explainability, and other topics. New research directions include boosting citizen science, stopping misinformation, and finding new treatments and vaccines for major diseases. The growth of research groups, conferences, journals, and research funding is an indication of interest in HCAI.
