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

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.

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.

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.

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.

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.

Abstract

In this paper we present a system for touchless interface using Kinect sensor. The system can be used for general purpose interaction with existing applications. We show a case study implementation for use with web-browser where user can interact with the content using gestures. We also present implementation of the game that uses presented system for handling interaction with the user. We also present advantages and disadvantages of such framework and give possible solutions for some of the problems.
