Part of what they're addressing is typographical convention and part is cognitive science.
Some folks seem to think typographical conventions are laws of nature and what these researchers are saying is that cognitive science says otherwise. That current conventions about white space, scan width, font size, etc, are products of the specific limitations of the technology of the codex and not necessarily binding on other technologies.
Maybe scrolling text can be more effective than paging, maybe single line crawlers can reduce eye strain, maybe a different form of text presentation can be more useful.

It's something worth exploring but I wouldn't expect definitive answers soon.
They may have to work with children to get past cultural bias and the tyranny of the familiar.
