In September, Adrian Hofbauer attended the 21st International Conference on Wirtschaftsinformatik (WI 2026) at Johannes Kepler University Linz, Austria. In the track "Human-Centered Information Systems & Social Computing," he presented the paper "How Justification Explanation Design and Domain Knowledge Shape Users' Cognitive Load and Trust in LLM-Based AI Assistants", co-authored with Prof. Dr. Ulrich Gnewuch. Using a custom-built RAG-based AI assistant, the study examines in an online experiment how the design of explanations affects users' cognitive load and trust, and what role their domain-specific prior knowledge plays. Realistic tasks from German income tax law served as the application context.
The paper grew out of Adrian Hofbauer's master's thesis. He has been a doctoral researcher at the chair since March 2026.
