The Multimedia Quality of Experience Research Lab (MUEXlab) is a research lab within the NetMedia group, Department of Telecommunications, Faculty of Electrical Engineering and Computing, University of Zagreb. The lab conducts multidisciplinary research in the areas of User Experience (UX) and Quality of Experience (QoE) modeling and management of advanced multimedia services, such as multiparty audiovisual communications, video streaming, virtual/augmented reality, and networked games.
A new contract was signed with the Croatian Science Foundation to fund the 4-year long project Modeling and Monitoring QoE for Immersive 5G-Enabled Multimedia Services (Q-MERSIVE)! The project will combine complementary expertise from engineering and networking (Faculty of Electrical Engineering and Computing, Univ. of Zagreb; Ericsson Nikola Tesla in Zagreb; Faculty of Traffic and Communications in Sarajevo), psychology (Faculty of Humanities and Social Sciences, Univ. of Zagreb), and interface/system design and usability (Faculty of Graphic Arts, Univ. of Zagreb), to achieve the following overall project goals:
- Propose novel QoE models for immersive 5G-enabled networked AR/VR applications and mobile multi-party conversational video communication services,
- Propose novel solutions for in-network monitoring of QoE and various Key Performance Indicators (KPIs), relying on machine learning-based techniques, as well as analytical approaches as applicable.
The project will kick-off in January 2020!
The Minister of Economy, Entrepreneurship and Crafts of the Republic of Croatia, Mr. Darko Horvat, visited the Center for Articial Intelligence at the Faculty of Electrical Engineering and Computing on October 14th, 2019. In the scope of the visit, the Minister and his collegues visited the Department of Telecommunications, where they met with reperesentatives from MUEXlab and IoTLab, both of which are a part of the Center for AI. MUEXlab representatives Lea Skorin-Kapov and Mirko Sužnjević discussed ongoing research activities and projects.
This years PhD Forum was held as part of the 27th International Conference on Software, Telecommunications and Computer Networks (SoftCOM 2019), in Split, Croatia, and was attended by 3 MUEXlab members. The event was organized with the help from Mirko Sužnjević who acted as a PhD Forum committee member, and a representative from FER. To participate on the PhD Forum, PhD students had to write a short abstract of their current research, hold a 2 minute pitch talk, and prepare and present a poster. Sara Vlahović presented her research area and results with the abstract and poster entitled QoE Assessment for Interactive AR/VR Applications, receiving the award for best pitch talk presentation. Ivan Bartolec presented his abstract and poster entitled The Implications of End-user Service Usage Behavior Patterns on In-network Video QoE Monitoring and Management, winning the second place for best pitch talk presentation.
EPSS19 Summer School on Machine Learning and Data Mining for Geo-Spatial Data, Quality of Experience and Human-Computer Interaction took place from 11th September until 16th September, in Würzburg, Germany, as part of the European Conference on Machine Learning and Principles and Practice of Knowledge Discovery in Databases (ECML/PKDD). It was attended by three MUEXlab members, Irena Oršolić and Ivan Bartolec, whom were both part of the QoE track of the Summer School, while Prof. Lea Skorin-Kapov held a lecture entitled "Assessing and Modeling Gaming QoE". The summer school had a strong focus on practical aspects. The participants got to know and learned to apply various machine learning and data mining techniques in their field of research.

Representatives from Rimac Automobili visted MUEXlab as a part of their visit to the Faculty of Electrical Engineering and Computing on Sept 6, 2019. Rimac Automobili is a high-tech Croatian-based company, manufacturing electric hypercars and providing full technology solutions to global automotive manufacturers. During the visit, we presented our ongoing research activities, with a focus on various applications of Virtual and Augmented Reality.
On 13th of June 2019, 17 undergraduate students visited Ericsson Nikola Tesla Zagreb as a part of the Multimedia Services course. The company visit provided students with the opportunity to learn more about the company, history of its collaboration with the Department of Telecommunications, new technology challenges and Ericsson's area of expertise. Students took a tour of the facility and got a first hand-look at network equipment and VR tile-based streaming service. Students were also given the opportunity to talk with people who are involved in the R&D. It was a great experience overall and students who were engaged the most won prizes. You can find the photo gallery here.

Mirko Suznjevic held and invited lecture on the Faculty of Teacher Education in scope of the "ICT in upbringing and education" course. The lecture was titled: "Virtual and augmented reality in early education".
Our PhD students, Irena Oršolić and Ivan Bartolec attended The 14th International Conference on Network and Service Management (CNSM 2018) in Rome, Italy. Irena presented a paper entitled In-Network QoE and KPI Monitoring of Mobile YouTube Traffic: Insights for Encrypted iOS Flows, co-authored with Petra Rebernjak, Mirko Sužnjević, and Lea Skorin-Kapov. She was also awarded with a student travel grant.
Members of the MUEXlab will present an application demonstrating different locomotion techniques in Virtual Reality at the University of Zagreb Fair. The fair will be held from November 21-24 this year in the premises of the Student Center in Zagreb. All interested students are invited to come visit us at our booth!
Our PhD students Sara Vlahović, Ivan Bartolec, and Irena Oršolić attended the PhD forum organized in the scope of International Conference on Smart Systems and Technologies (SST 2018), Osijek, Croatia.
