Prejudice and discrimination against immigrants have been a constant presence in Western Europe for a long time, fueled considerably by the refugee crisis in 2015. This project, supervised by researchers from Game Studies & Engineering and Psychology, explores the possibilities of using virtual reality (VR)-based video games to increase empathy and positive attitudes toward the integration of refugees in our society. Virtual-reality games have enormous potential for immersing players emotionally in situations outside their usual experience and in the perspectives of others. The project involves the development and evaluation of a game in which participants go through typical experiences of refugees in a European country and an experimental study that assesses the effects of playing the game on empathy, perspective-taking, and implicit and explicit attitudes toward refugees. We believe that this approach has the potential to open up a new, attractive route for changing people’s attitudes through immersive virtual experiences.

The project was proposed by Judith Glück from the psychology department and Felix Schniz and Mathias Lux from ITEC and accepted for funding within the Ada Lovelace program of the University of Klagenfurt. The project will start in Q3 or Q4 2023 and has a duration of 4 years.

Abstact: High-quality programming education at universities is a significant challenge due to rapidly increasing student numbers, tight teaching budgets and a shortage of instructors. The “CodeAbility Austria” project aims to meet this challenge by establishing suitable programming learning platforms. In this paper, we introduce the project in more detail, present the results of our empirical research on the experiences and challenges of using programming learning platforms, and provide an outlook for future work.

The kick-off meeting of the EU Horizon project – Graph-Massivizer (Massive Graph Processing of Extreme Data for a Sustainable Economy, Society, and Environment) took place from January 30th – February 2nd, 2023, at Klagenfurt University.
The Graph-Massivizer team comprising twelve international industrial and academic partners from Austria, Italy, Ireland, Slovenia, Norway, Netherlands, and Germany, pledged support to research and develop a high-performance, scalable, and sustainable platform for information processing and reasoning based on the massive graph representation of extreme data. Moreover, various aspects of the Graph-Massivizer toolkit, including five open-source software tools and FAIR graph datasets, were discussed in this meeting.

Collaborative Edge-Assisted Systems for HTTP Adaptive Video Streaming

Abstract: The proliferation of novel video streaming technologies, advancement of networking paradigms, and steadily increasing numbers of users who prefer to watch video content over the Internet rather than using classical TV have made video the predominant traffic on the Internet. However, designing cost-effective, scalable, and flexible architectures that support low-latency and high-quality video streaming is still a challenge for both over-the-top (OTT) and ISP companies. In this talk, we first introduce the principles of video streaming and the existing challenges. We then review several 5G/6G networking paradigms and explain how we can leverage networking technologies to form collaborative network-assisted video streaming systems for improving users’ quality of experience (QoE) and network utilization.



Reza Farahani is a last-year Ph.D. candidate at the University of Klagenfurt, Austria, and a Ph.D. visitor at the University of Surrey, Uk. He received his B.Sc. in 2014 and M.Sc. in 2019 from the university of Isfahan, IRAN, and the university of Tehran, IRAN, respectively. Currently, he is working on the ATHENA project in cooperation with its industry partner Bitmovin. His research is focused on designing modern network-assisted video streaming solutions (via SDN, NFV, MEC, SFC, and P2P paradigms), multimedia Communication, computing continuum challenges, and parallel and distributed systems. He also worked in different roles in the computer networks field, e.g., network administrator, ISP customer support engineer, Cisco network engineer, network protocol designer, network programmer, and Cisco instructor (R&S, SP).

Radu Prodan participated in the panel on “Fueling Industrial AI with Data Pipelines” at presented the Graph-Massivizer project at the European Big Data Value Forum on November 22 in Prague, Czech Republic.

The threat of climate change requires a drastic reduction of global greenhouse gas (GHG) emissions in several societal spheres. Thus, this also applies to reducing and rethinking the energy consumption of digital technologies. Video streaming technology is responsible for more than half of digital technology’s global impact [ref]. There is rapid growth, also now with digital and remote work has become more mainstream, in the amount of video data volume, processing of video content, and streaming which affects the rise of energy consumption and its associated GHG emissions.

The International Workshop on Green Multimedia Systems 2023 (GMSys 2023) aims to bring together experts and researchers to present and discuss recent developments and challenges for energy reduction in multimedia systems. This workshop focuses on innovations, concepts, and energy-efficient solutions from video generation to processing, delivery, and further usage.
