 Over the years the development and optimization of multimedia systems from traditional media (static 2D imagery and 2D video) to immersive media (manipulable 3D and XR) have been tailored towards delivering better experiences in remote communication. This has been essential for enhancing the sensation of presence and interactivity provided by immersive media, where users are no longer passive consumers but assume active engagement and decision-making. The topic has attracted a lot of attention from academia as well as industry players, with several publications and patents published every year on the topic, in addition to relevant standardization efforts from organizations such as ITU, JPEG and MPEG.

Despite remarkable advances, current Extended Reality (XR) applications are in their majority local and individual experiences. A plethora of interactive applications, such as teleconferencing, tele-surgery, interconnection in new buildings project chain, Cultural Heritage and Museum contents communication, are well on their way to integrate immersive technologies. However, interconnected, and interactive XR, where participants can virtually interact across vast distances, remains a distant dream. In fact, three great barriers stand between current technology and remote immersive interactive life-like experiences, namely the (i) content realism, (ii) motion-to-photon latency, and accurate (iii) human-centric quality assessment and control.

Overcoming these barriers will require novel solutions at all elements of the end-to-end transmission chain. This workshop focuses on the challenges, applications, and major advancements in multimedia, networks, and end-user infrastructures to enable the next generation of interactive XR applications and services. We hence encourage original paper submissions, which have not been published or submitted for publication elsewhere, from both academia and industry presenting novel research addressing the aforementioned challenges.

Topics of Interest

• Novel low latency encoding techniques for interactive XR applications
  
• Novel networking systems and protocols to enable interactive immersive applications. This includes optimizations ranging from hardware (i.e., millimeter-wave networks or optical wireless), physical and MAC layer up to the network, transport and application layers (such as over the top protocols);
  
• Significative advances and optimization in 3D modeling pipelines for AR/VR visualization, accessible and inclusive GUI, interactive 3D models;
  
• Compression and delivery strategies for immersive media contents, such as omnidirectional video, light fields, point clouds, dynamic and time varying meshes;
  
• Quality of Experience management of interactive immersive media applications;
  
• Novel rendering techniques to enhance interactivity of XR applications;
  
• Application of interactive XR to different areas of society such as health (i.e., virtual reality exposure therapy), industry (Industry 4.0), XR e-learning (according to new global aims), new building/CH management, etc.;
