1. Web Implementation of 3-way ChessJanez Koprivec, Matija Marolt, Ciril Bohak, 2025, independent scientific component part or a chapter in a monograph Abstract: This paper presents the design and implementation of a web-based platform for three-player chess, a non-standard variant developed by Dario Varga that until now has only existed in physical form. The work addresses several human–computer interaction challenges: intuitive visualization of a hexagonal chessboard, synchronization of three players in real time, and support for learning unfamiliar rules. The platform was developed using Node.js, React, Mantine, Socket.IO, and MongoDB, providing user account management, both single-device and online multiplayer modes, and access to game history. A key contribution lies in creating a user-friendly and responsive interface that lowers the entry barrier for new players while ensuring robust performance in real-time gameplay. Evaluation confirmed that the application meets functional requirements and offers minimal latency for online play, with results highlighting the impact of server proximity on player experience. The project demonstrates how thoughtful interaction design and modern web technologies can support the digital transformation of analog games, broadening accessibility and engagement with alternative chess variants.

2. Human-Computer Interaction in Slovenia : A Retrospective and Trend Analysis of Local ResearchCiril Bohak, 2025, independent scientific component part or a chapter in a monograph Abstract: This paper presents a retrospective and trend analysis of Human-Computer Interaction (HCI) research in Slovenia, with a focus on publications from national Human-Computer Interaction (HCI) conference venues between 2014 and 2024. Drawing on a dataset of 84 papers authored by 138 distinct contributors, we examine the evolution of research topics, author participation, and institutional involvement over time. The results show a relatively stable number of accepted papers per year, accompanied by fluctuations in author diversity, with 2022 marking a peak in community engagement. The analysis highlights both the persistence of core Human-Computer Interaction (HCI) themes—such as usability, interaction design, and visualization—and the gradual inclusion of emerging areas, including immersive technologies and data-driven design. By situating local contributions within broader international developments, the study provides an overview of the Slovenian Human-Computer Interaction (HCI) landscape, identifies patterns of collaboration and dissemination, and relects on challenges and opportunities for strengthening the community in the future.
