Interactive Session Guideline

Interactive Session Guideline
Speakers should upload their video files (2-3 minutes) and poster image files (A0 landscape) through the system by September 24, 2021.


Introduction to the platform: SpatialChat

We will use the platform for the poster session. This is an online communication tool based on an avatar. When the audience enter the room, the background of the room is filled with up to poster images. And the audience can control the location of their avatar by moving it using the mouse. By scrolling the button of the mouse, background image is zoomed in and out. The presenter’s avatar should be located within the area of his/her poster image. Note that this platform provides communication through camera and microphone, but the communication is enabled only when the participants get close to each other (that is, it is a distance-based chatting system as the name suggests).

How to prepare your poster?

You need to upload a pdf file that contains only one page of your poster. Its format should be landscape (not portrait), A0 size with at least 45 font size. If it is not easy to estimate the paper size with the font size, your poster file should look like this, and a sample PowerPoint file can be downloaded. While provides zooming in, its ratio is limited, and so, it is important that your font size is not too small.

How to prepare your short introductory video file?

Since is relatively new technology, it may be better to think about a contingency plan. For this, we recommend you to prepare a short (2~3 min) video file that briefly introduce your contribution. You may use your own poster or make a few pages of slides for the video. The detailed format of the video can be found in Guidelines for Oral Session. If you upload the video file (as well as the mandatory poster file), then we will post your video on the Online Program Book so that people can access your video any time during the conference.
