[ossrp-control] Re: What Is A Screen Reader?

Some of the best uses of drag-and-drop involve moving stuff between
windows, and when one window can obscure another, techniques like the JAWS
drag-and-drop become dicey.

I think the tasks of a new screen reader will involve as much knowing what
not to convey to the user as knowing what to convey.  That Windows screen
can really become a cluttered mess.

I have also found drag-and-drop to be unreliable and inneficient, even
with the JAWS hot keys for this.  I think the same functionality can
usually be provided through well-designed wizards.

Hi Laura,

It's interesting to hear that you find drag and drop easy in audio. If
it works well for you, that's great.

All I'm suggesting is that there may be a better way to achieve the same

effect as drag and drop in audio. As far as I know (and correct me
someone if I'm wrong) nobody has really looked into the alternatives.
Drag and drop was "invented" for visual displays. Is there an equivalent

or more powerful metaphor for audio?

What if you have to go to work at a new company and are unfamiliar with
where the icons are located on the desktop. The first time you use drag
and drop, you have to explore their spatial relationships. But why
should you need to do that? All you really want to do is be able to
associate one object with another and not worry about switching cursors
and moving them in certain directions. Perhaps there's a way to easy the

learning.

There is also room for improvement from an information theory point of
view. The key presses needed to switch cursor modes and the time needed
to move one object to another are not critical to the task of
associating object and action. By eliminating them, or reducing the time

it takes to perform them, you'd have a better interface, purely from an
efficiency standpoint.
