Jürgen Ziegler – HCI SI 2025 Keynote Speaker

Posted on by

We are happy to announce that the keynote speaker for HCI SI will be Prof. Dr. Jürgen Ziegler, from the University of Duisburg-Essen.

Title: Bridging the Gulf of Uncertainty in Intelligent Interactive Systems

Abstract:
The surge in AI technologies introduces new, useful functionality to interactive systems but may also increase uncertainty for their users. While traditional interactive systems cause uncertainty for users mainly through inadequately engineered functionality and user interfaces, intelligent systems inherently introduce uncertainty by applying probabilistic methods that mostly operate within opaque black box models. Uncertainty can significantly impair the user experience and trust in the system and have harmful effects on an individual or societal level. In this talk, Jürgen will discuss technical and cognitive sources of uncertainty and how to cope with them from a user-centric perspective. Using recommender systems as an example, he will propose principles for bridging the ‘gulf of uncertainty’ in user–system interaction. Specifically, the talk will address approaches to promoting user understanding of the decision space, enabling user control and exploration, and progressing from explaining AI functions towards co-operative human-agent systems.

Jürgen is a senior full professor in the Faculty of Computer Science at the University of Duisburg-Essen where he is conducting research in the field of Intelligent Interactive Systems. His main research interests lie in the areas of human-computer interaction, human-AI cooperation, recommender systems, social media, and information visualization.

PROGRAMME

8:30 – 9:00 Gathering
9:00 – 9:10 Welcome (Luka Čehovin Zajc)
9:10 – 9:45 Keynote: Understanding and Managing Quality of Experience for Emerging XR Services (Lea Skorin-Kapov, University of Zagreb)

Emerging eXtended Reality (XR) technologies have been recognized as a key enabler for the design of novel immersive experiences, often relying on the fusion of the digital and physical worlds. In particular, social and collaborative XR services enabling users to meet and interact in immersive environments have the potential of leading to an evolutionary step in communication services. Given service complexity, the availability of new hardware appearing on the market, and new application domains, the research community is faced with the challenges of exploring new methodologies, models, and metrics to understand and manage what we refer to as the Quality of Experience (QoE) or user experience (UX). UX/QoE research has thus received much attention over the past years and has become a prominent issue addressed by network, service, and content providers. Addressing these research challenges inherently calls for a highly multidisciplinary approach, combining expertise from disciplines such as engineering and networking, psychology, cognitive science, and human-computer interaction. In this talk, we will discuss key technologies and infrastructures needed to meet the requirements of emerging XR services, as well as key challenges related to assessing and modeling QoE.

9:45 – 10:30 Paper session (chair: Veljko Pejović)

  • Integrating Environmental Awareness into NPCs: Contextual Conversational Interaction in Games (Grega Radež and Ciril Bohak)
  • Music and Myth: The Relationship Between Music Preference and Unverified Beliefs (Elena Spirova, Arsen Matej Golubovikj and Marko Tkalčič)
  • The Role of Energetic Music in Video Game Immersion: Analyzing its Effect on Engagement and Performance Distraction (Teodor Kostovski, Matjaž Kljun and Klen Čopič Pucihar)

10:30 – 11:00 Coffee break

11:00 – 11:40 Keynote: Designing with Constraints: Real-Life UX Lessons (Amadea Derenda, Kaldi)

This talk explores the art of crafting effective user experiences when resources are limited, deadlines are tight, and teams are lean. Using real-world projects and case studies, we’ll dive into how UX principles adapt to practical constraints, what goes into the product lifecycle in non-academic settings, and the importance of securing stakeholder buy-in. Amedea will share insights how to balancing ideal UX practices with the realities of everyday challenges and the creativity it takes to make impactful design decisions, spanning from her 1/+ year career as a UX designer.

The Slovene Human-Computer Interaction (HCI) community has been present at the CHI 2024 Conference on Human Factors in Computing Systems this year as well. Looking at CHI statistics and seeing HCI being ever more popular in Slovenia is exciting.

Four authors from Slovenia were co-authors on full papers submitted and two were successful. Researchers form the University of Maribor published this paper:

Bhattacharya, Aditya, Simone Stumpf, Lucija Gosak, Gregor Stiglic, and Katrien Verbert. “EXMOS: Explanatory Model Steering Through Multifaceted Explanations and Data Configurations.” In Proceedings of the CHI Conference on Human Factors in Computing Systems, pp. 1-27. 2024. https://dl.acm.org/doi/10.1145/3613904.3642106

In addition, Jordan Aiko Deja from the University of Primorska was a Global Inclusion and Equity co-chair together with Martina Schuß, Technische Hochschule Ingolstadt, Germany, and Aimée Sousa Calepso, University of Stuttgart, Germany.

HCI SI 2023 flashbacks

Posted on by

The 8th HCI SI conference took place on Friday, January 26, 2024, hosted at the University of Maribor, Faculty of Electrical Engineering and Computer Science. The program delved into a diverse array of topics within the field of Human-Computer Interaction (HCI). These included investigations into methods for evaluating driver’s situational awareness and enhancing the precision of proximity sensors for vehicle parking assistance, utilising augmented reality for visualizing human anatomy, enhancing digital content with 3D-printed physical counterparts, improving the learning process of piano improvisation, and various other subjects. The keynote address was delivered by Dr. Elisabeth Lex from Graz University of Technology. Her presentation, titled “Trustworthy Recommender Systems,” provided attendees with insights into how recent research and emerging regulations in AI technologies impact ethical considerations such as bias, fairness, and privacy in the development of recommender systems.

See you!
