I can’t comment on anything specific to this year’s format, but having witnessed a lot of unsuccessful E-posters in the past, I can personally advocate (if possible for your particular content) a technique I have used for my own previously:
Have one “home / master slide” that summarises the work statically.
For each individual detail within that home page, insert a hyperlink in such a way that clicking on that detail forwards the presentation to some other slide.
Your other pages in the presentation then contain further details about specifics of the experiment / cohort / method / whatever that don’t all fit on the home slide.
At the end of each of these “blocks” of slides (you may have a sequence of multiple slides providing extra details on any particular topic), insert a full-page-size hyperlink that redirects back to the home slide.
You now have essentially an “overview” of the abstract, and can then digitally “zoom in” on individual details, subsequently “zooming out” back to the overview upon completion of discussion of those details.
Biggest trouble with E-posters is that people tend to produce a 15-minute presentation, which they get to present a couple of times in their hour block, to 1 or 2 people each time, because passers-by don’t want to start listening halfway through a linear presentation. This format gives passers-by regular opportunities to both grasp the key message, and ask for more information about whatever interests them.
