Oral presentation

  • For on-site speakers

Please connect to the Symposium Zoom at least 30 minutes before your talk and bring your PC to the podium to share your presentation file once the Q&A slot of your previous speaker is done. While you're talking, please use a microphone on the podium, not the one on your PC, which should be kept mute. You have the option to use the on-site public PC. In such cases, please upload your file more than 30 minutes before your presentation starts from our file upload website (to be announced).

  • For online speakers

Please connect to the Symposium Zoom at least 30 minutes before your talk and share your presentation file when the Q&A slot for your previous speaker is done. And please unmute your microphone before you start talking.
You can upload your pre-recorded presentation file or your presentation file in case you cannot attend the symposium on time or your zoom connection is unstable. In such cases, please upload your file more than 30 minutes before your presentation starts from our file upload website (to be announced).

  • For audience

When you connect to zoom, please remember to mute your microphone.
If you have a question for the presenter, please use the "Raise hand" button of zoom and unmute the microphone to ask a question, as the chairperson will assign you for online attendees.
For on-site attendees, please raise your hand to the chairperson and receive a microphone from our floor staff, as the chairperson will assign you to start speaking out. We will also prepare a public viewing space for the oral presentations next to the conference hall, where you can freely discuss with others during the session.

Poster presentation

  • For presenters

For on-site presenters, you can post your poster to the board on-site. The panel size is A0 (W841 x H1189 mm), and you can discuss it with the on-site audience in front of your poster.
The poster session is held also online via the breakout room function of Zoom. Every presenter will be assigned to a breakout room to share their poster. Any file format is acceptable (e.g., PDF, PowerPoint, Keynote).
Poster presenters participating online can give a five-minute flash talk. Flash talk will be held at the beginning of the poster session. Please connect to the Symposium Zoom at least 30 minutes before that time.

  • For audience

During the poster session time slot, you can freely access each poster site or breakout room of the posters. Please freely visit and discuss with the presenters. The breakout room for poster presenters will be open only during the session, so please make sure to attend the poster you are interested in. On-site attendees also have the option to talk directly with the presenters in-person during the time slot.
