TEST-1: EasyChair's Slide service: 

Check the Slide service by EasyChair on the program any time and leave some message to authors on SNS service such as Slack.

How to prepare your slide:

Log in to EasyChair for ECOS 2020 as "program author" account, then upload your "slide" for EasyChair Smart Slide Service, then publish your slide.

Please note that published slides cannot be un-published, so they cannot just be "published" temporarily.

Is the presentation with recorded video streaming service effective?

 Log in to EasyChair as "program author" then select "update information" to update the contents of your abstract.

Then add the URL in the "abstract" to access your video on the streaming service such as YouTube.


TEST-3': Online presentation at zoom meeting: 

We have approved the request for the VCS demo. However, EasyChair made a mock conference for our demo as a mini-session with only two talks.

Unfortunately, EasyChair does not allow more than 10 persons to participate in the demo-VCS. The VCS demo was for the conference organizer only so far.

So, we will set-up a zoom meeting for the special sessions at 21:00~22:30(JST) on August 31.

If you prepared for the TEST-3, please check the function of zoom meeting online presentation.

Please prepare your presentation material such as PowerPoint file to present online.


TEST-3: EasyChair's VCS meeting function:

By attending the special virtual session, check the availability of the virtual conference function of VCS.
