The sixth Workshop on User-Centered Artificial Intelligence (UCAI ’26) will be held in Duisburg, Germany, in conjunction with the Mensch und Computer 2026 conference, and is organized by the working group of the GI Section on Human-Computer Interaction, the SIG Nutzerzentrierte Künstliche Intelligenz (NKI).

Call for Contributions

The sixth Workshop on User-Centered Artificial Intelligence (UCAI ‘26) is entitled Human-Centered AI in Applications – Challenges and Promises and will address topics at the intersection of human-computer interaction (HCI) and artificial intelligence (AI), with the aim of strengthening human-centered design in AI-based applications.

A major goal is to explore and discuss how to empower users by making intelligent systems more transparent, interpretable, and explainable. Providing users with appropriate levels of interactivity and control over systems will be essential to fostering trust, accountability, and, eventually, facilitating the adoption of AI in practical settings, including high-stakes contexts. Counteracting potential biases in data and algorithms is another important lever to increase fairness, especially in applied contexts where decisions have real-world impact. There are also methodological gaps in evaluating AI-based solutions with respect to user experience, acceptability, and measurable business outcomes. Understanding how AI-generated outputs are perceived by users, and whether AI-based assessments can serve as valid proxies for human judgment, remain open methodological questions, especially for applications where expert knowledge is required.

Topics may include, but are not limited to, the following:

• Integration of generative and agentic AI into domain-specific workflows
• Design practices and tools for AI workflow augmentation
• Transparency and explainability of AI outcomes in application contexts
• Perception and validity of AI outcomes vs. human judgment
• Trust and user experience in applied AI
• Interactive control and customization of AI for application needs
• Conversational and mixed-modality interfaces for AI in applications
• User-centric evaluation and auditing of applied AI
• Ethical and legal considerations of deploying AI in applications

UCAI ‘26 aims at bringing together researchers and practitioners in the field of human-centered AI to discuss opportunities, challenges, and methods for AI-supported applications. The workshop will be held in a two-part format, comprising paper presentations and creative group sessions to identify and discuss the challenges and promises of AI systems in applications.
