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.
11:45 – 12:30 Paper session (chair: Ciril Bohak)
- UX Design: the Impacts on Physiological Responses (Natasa Miletic, Matjaž Kljun and Klen Čopič Pucihar)
- Guided by Steel: Teaching Shortest Path Algorithms with Robots and Overlaid Projections (Pavel Jolakoski, Jordan A. Deja, Matjaž Kljun and Klen Čopič Pucihar)
- Augmented Reality Training System Fusing the Triple Nature of Chemical Concepts (Maheshya Weerasinghe, Luka Ribič, Matjaž Kljun, Klen Čopič Pucihar and Iztok Devetak)
12:30 – 14:00 Lunch and Post-conference discussion

Challenges of Business Simulation Games — A New Approach of Teaching Business
Our members: Andrej Jerman Blažič and Franc Novak, have published a book chapter in book titled E-Learning – Instructional Design, Organizational Strategy and Management.

Abstract:
Serious games are part of the new emerging world of education environment that is based on sophisticated technology with elements of entertainment. They have been seen as good supplements for supporting the learning processes due to their capability to increase visualisations and challenge the student creativity. They have the potential to significantly improve training and education activities and initiatives. As a part of serious computer games, business simulation games support training and learning focused on the management of economic processes. They have been proven to be useful in empowering and mediating learning business content. This chapter addresses the simulation business games used in the educational process by analysing selected popular games regarding their properties that are considered as important in the learning process. The first part presents a short introduction in the field of business games and the approach used in selection of the studied games. The next part provides a review of related articles and brief overview of the state of the art that has guided the selection of business simulation games to be analysed and assessed. The game parameters used in the assessment have been defined and described. The analysis and the assessment report are followed with brief concluding remarks.

Mobile and responsive web applications
Mario Konecki
Abstract
Web technology has been a major factor of globalization for years. Modern technology has enabled web applications to be more complex because of greater data transfer speeds. Web quality is something that has come to focus as well as usability as one of its major aspects. Mobile applications have become popular since smartphones have gained greater hardware possibilities. The question that has presented itself is whether web technology can be as good as native mobile technology. The discussion about these two technologies is presented in this paper along with the research about the current popularity and utilization of responsive mobile websites.

Decision support in emergency call service
Miha Ristič, Franc Novak
Abstract
The emergency call service (telephone number 113) in Slovenia yearly receives more than half million calls. The communication between the caller and the policeman receiving the call is occasionally error prone due to stress and related conditions. From the above it is clear that a reliable operation of communication infrastructure and human resources is a prerequisite for efficient performance In this paper we explore possible ways of improving the emergency call service by providing decision support to the officer who receives the calls and dispatches a patrol to the place of the event.
Use of UX and HCI tools among start-ups
Bojan Blažica
Abstract
Today, User Experience (UX) and Human-Computer Interaction (HCI) tools can provide a competitive advantage that might be key of a company’s business success or failure. In this paper, the awareness and use of these tools among start-ups is examined with a survey. The results hint that there is lots of room for improvement in terms of raising awareness and adoption of tools that help companies deliver better experiences through their products.

Student’ acceptance of animated interactive presentation of sorting algorithms
Mario Konecki, Vladimir Mrkela
Abstract
Programming courses are very important and challenging part of computer experts’ education process. However, abstract nature of these courses makes them rather difficult for most students. In order to increase students’ motivation and level of comprehension regarding programming an approach that includes less abstract presentation of programming concepts using visualization techniques is proposed and implemented through the tool SortExpert that is designed to help the students to cope in a more suitable and easier way with various sorting algorithms. Discussion about the effectiveness of existing visualization tools and research about the evaluation and acceptance of SortExpert are also presented.

An improved visualization of LiDAR data using level of details and weighted color mapping
Sašo Pečnik, Danijel Žlaus, Domen Mongus, Borut Žalik
Abstract
This paper proposes an improved approach for LiDAR data visualization in terms of rendering quality. The method uses adaptive point-scaling for dealing with variations in data densities, while the contrasts of rendered objects are improved with weighted color mapping. In the former case, points’ distances from the observer are used to estimate their optimal rendering sizes. In the latter case, points are colored based on height attributes and increasing visual fidelity a point’s color is weighted using that point’s intensity information. Common image quality matrices, as well as conducted user study, confirm the improvements of the visualization.
