Yes, using multi-channel sound seems like it would be useful, or
alternatively a good 3D positioning scheme which encodes 3D sonic
information in stereo to be listened to via headphones...  I don't think
this is precise as vission, but it could certainly fill in the gaps so to
speak.

If you want to check out a game which uses this technique, check out the
game "Shades of Doom" from www.gmagames.com
There are other games which claim to do this, but in my humble opinion, this
is the only one which truly works and does it right!

Hi Rich,
Thanks for mentioning the shortcuts for traversing doc items on the Mac
side, that are different depending on the orientation of the doc. Yet
another feature that can easily require some notion of screen layout.

Usually in Windows, the direction stays the same regardless of physical
layout. For example, take opening sub-menus. Sometimes if there's not enough
space on the right, I've noticed the sub-menu may open at the left side of
it's parent or originating menu. Yet the logical keyboard shortcut to open
it is still the right arrow key. Also, I think the graphical arrow symbol
always points right.

Speaking of screen reader demos in presentations, I've got good experiences,
too. It was actually a course about scientific writing but I chose problems
of current screen readers from a user point of view and had a 15 minute
screen reader demo at the end with Supernova. The sighted people who were
present found the example helpful especially the bits about inaccessible
bitmapped text.

By the way, I've got enough sight to get some sparse layout info even
without magnification. Yet I cannot easily read text under say 28 pt, so I
use Supernova's magnification extensively. Also, apart from vague
recognizable shapes, I don't benefit much from icons either and would rather
turn them off to have a minimalist visual layout.

I also like the idea of being able to navigate freely in a certain direction
using virtual focus, view finder or whatever the screne reader specific
navigation mode is called. Though I do think that it might be very hard for
a totally blind person as it relys on layout information that the screen
reader doesn't ordinarily convey. Howabout conveying it with Torihara's
speaker matrix?

I find the idea fascinating and do have a real multi-channel sound card. An
unconventional speaker setup in which up is really up rather than forwards
might work well. Howabout using pseudo-surround sound with headphones as in
some games, is that feasible?

Just my two cents.

With kind regards Veli-Pekka Tätilä (vtatila@xxxxxxxxxxxxxxxxxxxx)
