General Information for Presenters

To provide a virtual TEI’21 conference for community members from all time zones, each contribution of the program will be presented twice (live and recorded). First, the live presentation will combine a pre-produced video with demos and discussions in Zoom. Then, the recorded presentation will be streamed on YouTube. In the breaks, following each session, presenting authors will be available in the corresponding Discord channels for informal discussions with the audience and further demos (if applicable). Please note that a registration is necessary to attend the virtual conference and engage in discussions. More information can be found in the program and Discord, you will receive the necessary link through CVENT after registration.

Live Presentation in Zoom

Preparation of the session: Presenters and chairs will receive a special Zoom link for panelists, and should log into their Zoom session at least 25 minutes before the session starts. Please make sure that you have a Zoom account and have installed the latest Zoom client. Session chairs should check if all presenting authors are present. The admins will assign all necessary access rights to the session chair and all presenters.

Introduction by the session chair: Welcome audience and authors (3 min).

Presentations: Total time per presentation 

  • Papers & Pictorials (15 min)
  • Work-in-Progess (10 min)

The control center plays the pre-produced video presentations according to the program. In case of any difficulties, contact the control center in Discord. Q&A are then read by the session chair from the Discord channel, any further author presentations and interactions are meant to be done through video chat and Discord rather than screen sharing.

Q&A: The session chair selects questions during the live program that are posted in the Discord channels, please avoid Zoom chat. If there are no questions in the channels and still some time, the session chair asks his/her own questions  (prepared in advance). Session chairs are expected to prepare a couple of questions per paper in advance. Please work with the authors to curate these questions. Authors should carefully think about the questions and be ready to respond briefly.

Closing the session: Thank you to the audience and presenters. Invite to further discussion in the Discord Channel during the following 30 min break. The control center interrupts the Zoom sessions and starts to stream the break time slide.
