How to do a good remote presentation?
Differences between a real in-person and a remote presentation are quite many, but the main key points of keeping an audience engaged remain the same. Assuming the audience can access the slides somewhere before or after the presentation, I would suggest to have pictorial representations of main concepts - use schematic diagrams and small bullet point sentences to assist them. Play around with bold fonts and highlight colours for texts, but not too much of any of these. There are many other good practices for giving a scientific and technical presentation, do perform a google search and find your preferred ones.
For a remote session, it is best to choose a platform where you can share your screen and keeping your video on, which actually adds a real feel to the presentation for the audience. It is good to have a plain background and silent environment as much as possible. If you choose a virtual background, make sure the software platform has had enough practice with it so that it can recognize between you and the background without patches of your face disappearing in the background. Structure your words more like a conversation and less like a monologue because even though the audience might be the best in this field, it is easy to zone out in such a session, so it is best to put in elements that attract attention and makes your talk easy to follow. Also, remember to number your slides/equations, etc so that they are easy to refer to.
Also, keep track of the time, if there is a chair or convener, probably they will give warnings, otherwise time yourself and don't rush or be overly slow, try to keep a steady tempo. A neutral tone is also a strong requirement for remote sessions because if your audience is spread across the planet, you don't want to come across as either a rude person or a bore.
I remember the speakers from remote sessions whose talks were natural and didn't seem too rehearsed and plastic. In the end, the content matters the most, but it is always pleasant to see it presented in an easier way - just like in a good paper.
