Re: Sluggish user experience on Facebook

Felix G.

Hello Enes and list,
sorry for my potentially confusing remark. I was not contrasting our
user experience with that of sighted users. Rather, I was implying
that some peculiarity of Facebook or the affected browsers might give
screen readers in general a hard time, and not just NVDA specifically.
So I did some testing, that is, I performed some comparative screen
reader theology, with the following results:
The late Window-Eyes, digital peace be upon it, occupies the slow end
of the speed scale combined with the high end of the accuracy scale.
You tend to get to wait quite some time for an answer, but when that
answer finally arrives, it is accurate to the degree of fully
supporting the weight of subsequent interactions.
JAWS seems to take quite the opposite approach, erring, when it does,
in favor of speed. There is the occasional unsolicited switch to focus
mode, as well as the occasional double-speaking of text, but the
snappy experience minimizes these frustrations.
NVDA currently takes what I call, from my perspective, the unfortunate
middle ground of this tradeoff. Applying this observation to Facebook,
it means that the experience is slow enough to feel sluggish, and just
unpredictable enough to feel nondeterministic as well. One can clearly
spot all the good intentions with which this particular road to hell
has been paved, so I wouldn't consider this proof that anything is
being consciously ignored, but the result, at least for me, combines
the worst of both worlds enough to make me switch screen readers when
using Facebook.
If, as Enes suggests, this observation applies to a broader category
of websites of which Facebook is just one prominent example, the
approach taken by NVDA in interacting with browsers deserves
reconsideration. Given the dynamic nature of todays's web, I strongly
suggest favoring speed over complete consistency. Selectively
decoupling focus from virtual cursor position, and re-coupling them on
demand, may be an effective first step in the right direction, as some
isolated speed cost when activating an element is allowable while a
permanent speed cost while navigating is clearly not.
All the best,

Yes, as sighted obviously do not have this problem, or we would've heard
more about by now.

so you're certain it's an NVDA issue rather than a Facebook or browser one?

This is an NVDA issue which has existed for about a few centuries, which
is also ignored by the devs. This happens not only in facebook, but in
many websites with dynamically changing content, or with dialogues, for
instance, the Oxford scholarship online database my university
subscribes to. This has to do with the way NVDA interacts with the
browser, however a better way was not implemented.

Hi everyone,
is anyone else noticing that when arrowing or otherwise navigating
Facebook's standard view, the interface tends to slow down to a crawl?
In addition, I am experiencing the virtual cursor randomly jumping
back a few lines, resulting in lines being read twice, and random
switches to focus mode.
Are there any known remedies, except of course switching to mobile
view, which is not even recommended to blind users by Facebook itself?
All the best,
