Category: About the project

Within the QoE4VR project, we are eager to find out the connection between network related parameters (such as latency, packet loss, jitter, bandwidth and others) and human perception of quality of Virtual Reality applications.

Our group of researchers is maybe small, but we overcome the lack in numbers with our enthusiasm, scientific curiosity and overall hard working. The team leader is professor Stefica Mrvelj – experienced researcher in the telecommunication field. Members of the team are Mario Mustra and Marko Matulin (with expertise in video quality, coding, evaluation, QoE, QoS) as well as Tomislav Fratrovic, Diana Rupcic and Marijana Greblicki (all expert mathematicians and data analysts).

The QoE4VR project is funded by the University of Zagreb, Faculty of Transport and Traffic Sciences. The project started in June 2017.

Work Plan

The work within the QoE4VR project is divided into stages. Namely, there are three major milestones along the way: (1) establish the test environment, (2) conduct the subjective tests with the subjects and (3) analyze and publish the results. Continue reading to find out more about the tasks within the specific stages that will lead us towards achieving the milestones. Continue reading “Work Plan”

General info

Summary

The focus of the QoE4VR project is the analysis of user Quality of Experience (QoE) when using Virtual Reality (VR) applications in different network conditions. The objective is to find out the correlation between the level of user QoE (i.e. his or hers subjective perception of quality) and values of measurable network parameters such as latency, packet loss, video frame rate etc. Continue reading “General info”
