CHI 26 Workshop

Welcome!

📅 April 14, 2026 | 🙋 In Person | 📍Barcelona, Spain

Welcome to our fifth workshop on User Interface at CHI. This year we explore Human-AI-UI Interactions Across Modalities, focusing on how UIs should be designed to enable intelligent agents to effectively interpret and interact with interfaces across 2D and XR environments and how UI agents should be designed to help users understand and use UIs. We bring together researchers from different sub-disciplines of HCI and adjacent fields (ML, CV, NLP, Software Engineering) to discuss how multimodal UI design can support AI as collaborative partners, and how these interfaces must evolve to facilitate human-AI interaction across diverse modalities.

「UI on Demand」

Today's AI interactions are almost entirely conversational, and for many tasks, that works well. But sometimes you need to sketch what words can't capture, explore possibilities you can't name yet, or step back to overview the full picture. Recently, people have begun exploring generative UI, synthesizing interfaces on the fly within a conversation. In this talk, I show what this might look like, drawing on several systems I built that explore different interaction abstractions for steering AI, from sketching and puzzle pieces to maps and genetic evolution. Can we generate the interface right, and the right interface to generate?

Previous Highlights

This workshop continues a vibrant tradition that began in 2022. Over the past four years, our community has gathered annually at CHI to explore the evolving landscape of computational approaches to user interfaces. Each workshop has tackled emerging challenges as AI capabilities and human needs have transformed:
