XAI for U 2026
Explainable AI for Ubiquitous, Pervasive and Wearable Computing. A workshop on transparency for AI systems embedded in the things we wear, carry, and live with.
Explainable AI for Ubiquitous, Pervasive and Wearable Computing. A workshop on transparency for AI systems embedded in the things we wear, carry, and live with.
The XAI for U workshop addresses the need for transparency in AI systems increasingly integrated into mobile devices, wearables, and smart environments, many of which remain opaque to users, designers, and stakeholders—undermining trust and adoption. The workshop focuses on Explainable AI (XAI) tools tailored to this domain and its distinctive challenges: generating explanations for time-series and multimodal data, interpreting interconnected machine learning pipelines, and delivering user-centered explanations. By bringing together researchers across related disciplines, it aims to share recent advances, surface open challenges, and propose future research directions, so that AI-driven ubiquitous solutions become not only more explainable but also better aligned with user expectations and ethical standards.
Original research, insightful case studies, and work-in-progress on XAI approaches for ubiquitous and wearable computing, including but not limited to:
Explanation methods tailored to wearable and IoT settings, including multivariate time-series and heterogeneous sensor streams.
Explaining end-to-end pipelines (pre-processing, segmentation, classification) rather than individual models in isolation.
Explanation strategies that adapt to user needs, context, and the dynamic environments typical of ubiquitous systems.
Empirical evaluation of explanations, including faithfulness metrics, user studies, and over- or under-reliance on decision-support tools.
Deploying XAI on resource-constrained wearable devices, with attention to privacy, fairness, and alignment with the EU AI Act.
Domain applications of XAI in healthcare, mental health, human activity recognition, and smart-home/smart-environment systems.
Approaches that combine symbolic reasoning, neuro-symbolic models, and LLMs for generating and verbalising explanations.
