Apologies for cross-posting. ********************************************************************************** MUM 2021, 20th International Conference on Mobile and Ubiquitous Multimedia December 5-8, 2021 Leuven, Belgium ********************************************************************************** # Important Dates MUM is an interdisciplinary forum for advances in research of mobile and ubiquitous multimedia systems, applications, and services. At MUM, academics and practitioners gather to discuss challenges and achievements in this field from diverse perspectives, such as interaction techniques, user research, system development, software solutions, and devices. This edition of MUM aims to continue the tradition of innovation and excellence in research established by previous MUM conferences. This year, we have all been confronted with significant changes caused by the corona virus outbreak. Based on vaccination data coming from Europe, the USA, and other countries, we are confident that MUM 2021 will be able to be organized physically. However, we plan for it to be a hybrid in-person event with support for remote participation for those who might not be able to travel to Belgium. We are currently considering which solution to use to be as inclusive as possible to those who will prefer to present and participate remotely. We will monitor the unfolding of the events in the short term and update the conference modality accordingly. We welcome submissions of high-quality papers that offer original and unpublished contributions relevant to the field of mobile and ubiquitous multimedia. Paper topics include, but are not limited to, the following: * Architectures, systems, algorithms and other constructions tackling relevant technical challenges * Augmented, mixed, and virtual reality systems and applications * Case studies, field trials, or user experience evaluations of new applications and services * Conceptualizations and theorizations of the field * Context-aware and location-based mobile and ubiquitous services * Metrics and measures for evaluating and testing mobile and ubiquitous systems * Middleware and distributed computing support for mobile and ubiquitous multimedia * Novel applications for mobile and ubiquitous gaming, entertainment, networking, and advertising * Privacy and security related issues to multimedia systems * Social implications of mobile and ubiquitous multimedia systems * Tools and development environments for building mobile, wearable, and ubiquitous multimedia systems * User interfaces, interaction design, and interaction techniques for mobile and ubiquitous systems * Papers should be grounded in existing literature and knowledge, and should be written for an * interdisciplinary audience. Papers must be submitted via EasyChair at the latest by August 6th, 2021 * AoE. An application for inclusion of the conference proceeding in the ACM International Conference * Proceeding Series is currently being processed. # Submission and Templates The correct template for submissions is the ACM Primary Article Template in single-column format (in PDF format). Submissions should be prepared using either the single column Word Submission Template or the single column LaTeX template (using the “manuscript, review, anonymous” style available in the template). Submissions can be of variable length. Paper length must be based on the weight of the contribution with 16 pages (excluding references) in single column format being valued as long papers in past editions and 7 pages (excluding references) in single column format being valued as short papers in past editions. Successful submissions of around 16 pages typically represent significant empirical, theoretical or methodological advances in the field. Successful submissions of around 7 pages offer more focused contributions; they are not intended to be work in progress reports but, instead, they offer complete, rigorously developed work, with a solid contribution to the field. Short papers have a smaller scope or more focused contribution than long papers. Submissions should not have been previously published or be concurrently under submission. Papers must be anonymized. Submitted papers will undergo a rigorous double-blind review process managed by the Program Chairs. Each submitted paper will be reviewed by at least three reviewers, chosen from the pool of members of the Program Committee listed below. This pool of reviewers features both experts from the previous edition, as well as new researchers to address new emerging research areas and underrepresented communities. Papers will be assigned through a bidding process. Authors are encouraged to submit an optional video of maximum 5 minutes to support their submission. To ensure videos can be viewed by all reviewers, authors should preferably use the H.264 encoding and the MP4 file format. To accommodate the upload limits of EasyChair (max. 50mb per file), the bit rate of videos can be lowered. # Reviewing process There will be a single round of reviews with three potential outcomes: desk-rejects (papers that are significantly out of scope, not written in English, etc.), rejection, and conditional acceptance. No rebuttal phase is planned. Authors of conditionally accepted papers will find in the reviews a list of revisions and requested changes they need to satisfy to have their paper be officially accepted into the program. At least one author from each accepted paper must register to the conference. # Organisers: Adalberto L.
