Challenges of Human Oversight: Achieving Human Control of AI-Based Systems (Dagstuhl Seminar 25272)

Authors: Markus Langer, Raimund Dachselt, Q. Vera Liao, Tim Miller, and Nava Tintarev

Published in: Dagstuhl Reports, Volume 15, Issue 6 (2026)

Abstract
Human oversight is a key safeguard for AI systems, intended to mitigate risks by adding a human layer of safety and control. Oversight personnel should, for example, detect malfunctions or violations of fundamental rights such as discriminatory decision-making and intervene accordingly. Human oversight is also central to AI governance and ethics, and is mandated by Articles 14 and 26 of the EU AI Act for high-risk AI. This Dagstuhl Seminar brought together experts from artificial intelligence, human-computer interaction, human factors and psychology, philosophy and ethics, and law to explore conceptual, technical, legal, and practical dimensions of human oversight of AI. Across the seminar, participants provided perspective talks from the different disciplines and engaged in working groups and use-case specific discussions in order to establish a science of human oversight of AI systems. The main outcome of this seminar is a general framework that outlines the architecture, processes, and sociotechnical design dimensions of human oversight of AI systems.

Visualizing Data on Non-Flat, Non-Rectangular Displays (Dagstuhl Seminar 25082)

Authors: Anastasia Bezerianos, Raimund Dachselt, Wesley J. Willett, and Ricardo Langner

Published in: Dagstuhl Reports, Volume 15, Issue 2 (2025)

Abstract
Experiences with data, visualization, and computing more broadly are mediated via flat, rectangular displays. However, an exciting range of new display technologies, including flexible, spherical, physical, and even robotic and drone-based displays, have recently emerged and are increasingly commercially available. These novel types of displays offer new ways to represent, explore, communicate, and share data, yet there is very little understanding of how to best utilize these novel form factors for data visualizations. This Dagstuhl Seminar aimed to escape from the display flatland that characterizes research in visualization, and to create a roadmap for future research on interactive non-flat displays. Bringing together researchers from data visualization, human-computer interaction, ubiquitous computing, tangible interaction, mobile and wearable technologies, and design, we surveyed the landscape of emerging technologies, ideated future opportunities for visualization on non-flat displays, and outlined a common research agenda for this emerging area.

Mobile Data Visualization (Dagstuhl Seminar 19292)

Authors: Eun Kyoung Choe, Raimund Dachselt, Petra Isenberg, and Bongshin Lee

Published in: Dagstuhl Reports, Volume 9, Issue 7 (2020)

Abstract
Mobile visualization is becoming more prevalent, and new mobile device form factors and hardware capabilities will continually emerge in the coming years. Therefore, it is timely to reflect on what has been discovered to date and to look into the future. This Dagstuhl seminar brought together both established and junior researchers, designers, and practitioners from relevant application and research fields, including visualization, ubiquitous computing, human-computer interaction, and health informatics. Five demos and five tutorials gave participants an opportunity to share their experiences and research, and learn skills relevant to mobile data visualization. Through brainstorming and discussion in break-out sessions, along with short report back presentations, participants identified challenges and opportunities for future research on mobile data visualization.
