As part of the TRANSMIXR work on metrics and evaluation, the research carried out by the Distributed and Interactive Systems (DIS) group from Centrum Wiskunde & Informatica (CWI) has resulted in two contributions to ACM Multimedia Conference (ACM MM 2023). ACM Multimedia is the worldwide premier conference and a key world event to display scientific achievements and innovative industrial products in the multimedia field. It is the flagship of the ACM Special Interest Group on Multimedia (ACM SIGMM) which provides a forum for researchers, engineers, and practitioners in all aspects of multimedia computing, communication, storage, and applications. This year, ACM MM was held in Ottawa, Canada from October 29th to November 2nd, 2023.
The DIS team presented two workshop papers: “Correlation between Entropy and Prediction Error in VR Head Motion Trajectories”, and “Subjective Quality Evaluation of Point Clouds using Remote Testing”. The first one was presented by Silvia Rossi and explores the relationship between the way in which users interact with immersive content and the predictability of their trajectories. While the second contribution, presented by Ashutosh Singla, investigates the applicability of remote testing by using Absolute Category Rating (ACR) test method for assessing the subjective quality of point clouds in different test environments (e.g., lab-based tests).

In addition to the previous publications related with TRANSMIXR, DIS group were involved in other important activities during ACM MM. Pablo Cesar participated at the SIGMM retreat, an important occasion for the leadership of SIGMM, ACM Multimedia and other SIGMM conferences to discuss the most important challenges that the multimedia community is now facing. Irene Viola co-organised and held the workshop “Interactive eXtended Reality”, with the above presentations from Ashutosh Singla and Silvia Rossi. Irene held and moderated a panel titled “On the Impact of Interactive eXtended Reality: Challenges and Opportunities for Multimedia Research”. Silvia Rossi, instead, was an invited panellist in the panel “Multimodal Large Foundation Models” organised by Marcel Worring (UvA, The Netherlands) and Mohan Kankanhalli (NUS, Singapore). Finally, Silvia was awarded the 2023 SIGMM Award for Outstanding PhD Thesis in Multimedia Computing, Communications and Applications for her PhD thesis entitled “Understanding user interactivity for the next-generation immersive communication: design, optimisation, and behavioural analysis”.
