Hi, Happy New Year everyone (and an early Happy New Year to those in
I'd like to comment on the 640x400 accessibility issue. I agree that
this is desirable for
accessibility, but since 640x480 is getting less and less common,
perhaps 800x600 is
a better target for now. A 'virtual' 800x600 (with a physical 640x480),
which I believe
XFree supports now, may be a good compromise, since it allows
applications to write
to a somewhat bigger virtual area in which the 640x480 area is panned.
What's possibly even more important is support for larger fonts; 12
point isn't usually
big enough for users with vison difficulties, unless fullscreen
magnification is available
(KMag can't do that yet, and even gnome-mag/gnopernicus has a hard time
have two framebuffers).
I think 18 to 20 point fonts are a reasonable target. This will
(especially in conjunction
with 800x600 displays) probably be harder to accommodate than just
640x480, but it's
really important. I would argue that working well with such large fonts
is actually more
critical to accessibility than working with a limited screen resolution.
There's no reason why this is impossible, but it requires careful design
of widget sets
and user interfaces.
