IPTC Researchers Explore the Future of Immersive Communication
Researchers from the Information Processing and Telecommunications Center(IPTC) at Universidad Politécnica de Madrid (UPM) have presented a new study on immersive communication systems, exploring how people experience remote interaction using advanced Free Viewpoint Video (FVV) technologies.
The research evaluates how different display technologies — traditional 2D screens and Virtual Reality headsets (HMDs) — affect users’ Quality of Experience (QoE), social connection, communication ease, and sense of presence during remote collaboration tasks. Using a real-time FVV system with multiple cameras and 6 Degrees of Freedom navigation, participants could interact with remote environments almost as if they were physically there. The study involved 54 participants performing a collaborative task while researchers analyzed factors such as interaction quality, task performance, immersion, and cybersickness.
Beyond the specific findings, the work is especially relevant because it contributed to the development of the new international ITU-T P.1321 recommendation for evaluating immersive communication systems.
Potential applications of this research include remote collaboration, telepresence, education, healthcare and rehabilitation, virtual events, entertainment, and future immersive workspaces.
The article was presented on May 4th at the IEEE International Conference on Acoustics, Speech, and Signal Processing (ICASSP) in the Workshop on Data Science for Telepresence and Extended Reality Applications.
