Virtual Conference Guide for Attendees

Virtual Conference Guide for Attendees

Though it is not complicated, we still need your attention to read all the guides before the conference starts. It is the first time we run this conference virtually and for many of you, and it may be the first time for you to attend a virtual conference. There indeed many things are different compared with an in-person conference. Although we have spent numerous time to make it easy to follow, it may be still not intuitive. Therefore, please be patient and please do read the guides before the conference.

This is the guide for all ACM Multimedia 2020 attendees as “generic audience” (instead of session chairs or paper presenters or speakers) to participate the conference.

Please note: If you’re a presenter for a paper/demo etc., please also read the Live QA Session Presenter Guide besides this guide.

Please note: If you’re a speaker or session chair for a single track live sessions (including conference opening/closing, keynotes, panels, industrial talks, best paper session, SIGMM business meeting, award ceremony, SIGMM Tech Achievement Award talk, SIGMM Rising Star Award talk, handover meeting), please also read check your email about “ACM MM20 Main Conference Single Track Live Session Presenter Guide” besides this guide. If you have not received this email, please ask your session chairs (for speakers) or general chairs (for session chairs).

Again, the year of 2020 is indeed destined to be an unprecedented year full of turbulence and challenges. Due to COVID-19, ACM Multimedia 2020 is forced to be held in a 100% online format for the first time in its long history. With this constraint, it is clear that it is not possible to work out a perfect solution so as to accommodate every conference participant from all different time zones. In consultation with the SIGMM Executive Committee, the Organizing Committee of MM2020 has adopted a principle to accommodate as many attendees as possible from different time zones during the main conference events. You can find our temporary program schedule at

Important: There are three types of programs in the virtual conference:

  • Pre-recorded videos
  • Main conference single track live sessions
  • Live question and answering (QA) sessions

All these will be embedded (as video playing window or link) in the one-stop conference app: Whova. You can either download Whova Mobile App, or you can use Whova Web App. Please use your email for conference registration to register Whova app account, and ACM Multimedia 2020 will be automatically shown in your Whova app.

About Whova app: Please watch this short video to get to know the main features of Whova, and read the attendee guide of Whova.

Pre-recorded videos: In Whova (either Whova Mobile App or Web App), we have pre-recorded video presentations for all papers (including main conference regular papers, accepted submissions of other tracks, and also tutorials) with a few exceptions (that means, the authors didn’t provide videos). Typically, the length of the video is 15 minutes (for regular oral papers) and 5 minutes (for most other presentations). Tutorial videos may be as long as one or more hours. The video is shown as “Recorded Video” in Whova. Please read the attendee guide of Whova for more details about using Whova.

Please note each paper of the conference will have one recorded video and two mirrored QA sessions (please read on for more details about the QA sessions). Pre-recorded videos will be published online for on-demand streaming. No time slot will be allocated for showing these videos. All participants are encouraged to watch the video presentations before going to the corresponding live QA sessions.

For each paper in Whova App, you can read the paper in PDF version stored in ACM Digital Library through the associated link. And an alternative video link is also provided, which you can click if you find the embedded video play is not smooth enough. This information is listed in the paper description.

Main conference single track live sessions: This type of programs includes conference opening/closing, keynotes, panels, industrial talks, best paper session, SIGMM business meeting, award ceremony, SIGMM Tech Achievement Award talk, and SIGMM Rising Star Award talk. Here are the list:

All single-track programs are scheduled during the “golden four hours” (when 2/3 of the world is awake!). This is consistent with other major online conferences. To be exact, we will use EDT (UTC-4) 9:00-13:00 as the golden time slot. It will be 6:00-10:00 US West/Seattle, 21:00-01:00 Beijing time and UTC 13:00-17:00. Under this arrangement, people from Asia will be staying up a bit and US West people need to get up earlier a bit, while most other parts of the world will be fine. And, we have to say sorry to people from Australia.

Please use Whova to get the Zoom Webinar link for the main conference single track sessions. Please use Zoom App or Zoom Web App to join the Webinar. When you enter Zoom by following the link, please enter your name and an email address (not necessarily your Zoom account) and then wait the host to start the Webinar (if it has not started yet). You will be an “Attendee” of the Webinar after entering. If you’d like to ask questions, please use “Chat” function to input your question using text, or please click “Raise Hand” to ask for a permission to speak.

Please note we will use the same Webinar for all the sessions on the same day. That is, the Webinar will continue without stop though we will switch from opening to keynote, from keynote to panel, etc. As an attendee, you don’t need to leave and rejoin when we switch sessions.

Live QA Sessions: Besides the pre-recorded videos, two mirrored live Q&A sessions will be scheduled for each paper (for main conference regular papers and tutorials) or each session (for some main conference tracks). The idea about the live Q&A session is like an in-person poster presentation, which allows a direct interaction between the interested attendees and the authors.

The two live Q&A sessions will cover most of time zones, and this will give all attendees over the globe the opportunities to interact with the authors. You can choose one of them to attend.

For main conference regular papers, the QA live zoom meetings for the papers in one particular session will be running in parallel. This arrangement will allow attendees to ask questions of all the papers in this session in one hour, by switching among the corresponding Zoom meeting rooms. Alternatively, if we schedule the QA meetings in sequential for the papers in one particular session, an attendee needs a few hours to go through all the QA meetings for the papers in the session, which is too long. This is the reason why we run the zoom meetings for the papers in one session in parallel.

In Whova agenda, you can get the link of the QA meeting for each paper. Please use Zoom App or Zoom Web App to join the meeting. You can join the meeting any time (within the scheduled one hour) to ask questions. In Live QA Zoom meetings, you’re allowed to ask questions any time without raising hand, but please note the meeting host may mute all attendees at the very beginning of each paper QA thus he or she can introduce the paper briefly before question asking and answering.


Doctoral Symposium: Please be noted doctoral symposium will be running as a live session using Zoom Webinar. Please follow the same instructions as “Main conference single track live sessions” though it will be running in parallel with other sessions.

Tutorial 2: Deep Learning for Privacy in Multimedia: This tutorial will be running as a 4-hour live session using Zoom meeting and it will only run once. The format of all other tutorials is: pre-recorded video + two mirrored one-hour QA sessions.

Workshops: All workshops will be running as live sessions. Please join the corresponding Zoom meetings at the workshop time through the link provided in Whova. Attendees may be muted by the workshop organizers unless it is the time for question answering. Some workshops may also have pre-recorded videos available.

We hope you will have an enjoyable experience on the virtual conference. If you have any questions, please let us know.
