Leuven, Belgium


MUM 2021, the 20th International Conference on Mobile and Ubiquitous Multimedia will be held in Leuven, Belgium, December 5th - 8th.

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.

The MUM poster track provides an opportunity for researchers and practitioners to show and discuss their recent work on mobile and ubiquitous multimedia systems, services, interactions and experiences. The submissions can also be about something that has not been fully designed, implemented or tested but shows great promise, has a provoking topic or only preliminary results, or summarizes several small-scale studies. Topics of interest are the same as mentioned in the CfP for short and full papers. Posters provide the opportunity for researchers to get feedback on early-stage work, discuss potential collaborations and burning issues in an informal manner with the MUM community.

Topics could 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

Poster submissions should be maximum 3 pages (excluding references). 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). Poster submissions must contain an abstract with less than 150 words that clearly states the poster's contribution to the field.

Submissions will undergo a review process managed by the poster chairs. The authors of the accepted posters will receive instructions about the format of the poster. Poster must be submitted via EasyChair.

Accepted submissions will be presented as a poster at the conference. Authors are expected to bring the accepted posters to the conference site with them and be present throughout the posters and demos session of the conference.

Submissions should not have been previously published or be concurrently under submission elsewhere. Submissions should be anonymized and will undergo a double-blind review process. Final camera-ready versions of accepted submissions must be accompanied by a signed copyright form. An agreement to publish the accepted poster papers in the ACM Digital Library is currently being negotiated.

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.
