Ah. http://www.nngroup.com/reports/mobile-website-and-application-usability/ looks like it might be the actual report, but I'm not about to drop $300 to find out. Even that looks like it's mainly a set of guidelines aimed at web developers extrapolated from the research, and the actual _foundational research_ looks to be skipped over in only 11 pages, according to the table of contents (there's an excerpt freely available which includes the contents). It's also not the original 2009 report, but a 2011 update, though presumably the short write-up of the studies includes the 2009 ones. Again, Nielsen's actual piece on masking only mentions any study at all very briefly, in passing: "Password masking has proven to be a particularly nasty usability problem in our testing of mobile devices [hyperlink to http://www.nngroup.com/articles/mobile-usability-update], where typing is difficult and typos are common. But the problem exists for desktop users as well." That's it. So far as I can see, that's the sole reference to any actual identifiable study. And again, so far as I can see, the entire 2009 debate spiraled out from that single post, with lots of 'experts' adding their subjective $0.02 on either side (mostly against), but no-one actually adding any kind of useful empirical research. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | identi.ca: adamwfedora http://www.happyassassin.net -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
