RE: [emacspeak The Complete Audio Desktop] Web Accessibility AndUsability: Comin...



I agree we need a challenge, but I would argue that rather than Nielsen, we
should challenge ourselves to bring the efficiency and effectiveness of
Emacspeak to more people.  After all, Nielsen's conclusions are
scientifically valid for probably 99% of all persons with disabilities
currently online.

How this should or can take place, I do not know. But I think we cannot
blame users for falling into the trap of inferior tools when they are not
aware of alternatives and when the alternatives are so difficult to find,
install, and learn.

I have been trying to figure out ways to make access to Emacs easier, and
have also thought about finding a way to fund a scientifically valid study
where Emacs is compared to more conventional tools, so I am glad to see
Raman bringing that idea up.  If anyone would like to be part of such a
study, or has suggestions of potential funding sources, etc, please contact
me directly.

You raise very valid points, Raman. Perhaps we might consider a challenge to
Nielsen. Perhaps we could point out that their presuppositions are unfair
and lead to unhelpful conclusions? As you point out, it's the task, not the
particular web site for that task, which matters. And, the performance of
users with minimal skills and inadequate tools is certainly a questionable
measure.
