In this CHI 2026 workshop 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. The workshop is co-organized by Felix Kretzer and Alexander Maedche from the human-centered systems lab with colleagues from University of Utah, Carnegie Mellon University, Apple, and University of Bath.   

The deadline for submissions is February 10th 2026. Further information is available here: https://sites.google.com/view/computational-uichi26
