Navigation system proposal -- Vision Impaired Interface

This is a proposal for how the vision-impaired interface would work for the
demo.

This is intended for voters that have the ability to,

- Hear and understand spoken instructions
- Use the arrow keys on a standard 101 PC keyboard
- Pick up a piece of paper from the printer and place the paper in a privacy
folder

For the demo, we won't be able to address issues for people with
disabilities beyond this. We should probably have some statistics to show
what percentage of the disabled community this covers and state that other
interfaces will be explored when the production software is developed.

There would be three basic levels: instructions, contests, and choices.
Contests and choices would consist of lists. Each contest has an
introduction and a detail list. After all the contests have been covered,
we go to confirmation/correction mode.

The arrow keys would function something like this:

Up arrow: like the Esc key; abandon, go up one level

Dn arrow: like the Enter key; select,

Left and Right arrows: skip through the list left or right

It would actually be possible to cast a ballot using only the Dn arrow
(select). In other words, you finish the instructions by hitting select.
Then you'd go straight to the first contest. You finish the first contest
by hitting select when you hear the desired choice. This would take you
automatically to the next contest and so on. After the last contest, you
review the selections made. If okay, hit select again to print the ballot.

There would be a quick list and a slow list. The quick list is to introduce
all the choices. The slow list is where the voter would pick the desired
choice (by hitting down arrow). But there would be no need for a quick list
on yes/no contests.

The instructions would go something like this:

***********
To vote, you will print your ballot and place it in the privacy folder.
Please locate the arrow keys on the keyboard and press a key.

[at this point, give some feedback like, "no, that's the End key. The arrow
keys are below that one." Or, "no, that's the Shift key. The arrow keys are
to the right." or "yes, that's the down arrow. Now press the Up arrow." And
so on.. until they've located all the arrow keys. ]

Good! Now locate the privacy folder. If you do not have a privacy folder,
please ask a pollworker for one now. Press the down arrow to continue after
you have located your privacy folder.

Before printing your ballot, we have to cover three subjects: the
instructions, the contests, and the choices. When you are done with the
instructions, press the down arrow to go to the contests. If you want to go
back to the instructions, press the up arrow.

We will go over each contest one-by-one. The contest will be described and
the choices listed so you will hear all of them. Then the choices will be
listed slowly. When you hear the choice you want, hit the down arrow to
select.

When the lists of contests and choices are being read, you can skip ahead or
go back with the right or left arrows.

Hit the down arrow to go to the contests, or hit the up arrow to hear the
instructions again.

FOR PRESIDENT AND VICE PRESIDENT OF THE UNITED STATES

The candidates are ...

[read the list of candidates quickly (introduction). At this point, hitting
the up arrow would go back to the instructions; the down arrow would skip
the quick list and go to the slow list (detail list); the right arrow would
skip this contest and go to the next one; the left arrow would go to the
last contest. If the slow list is read but no selection made or if the left
or right arrow is hit during the introduction, we say, "No preference was
indicated for President and Vice President" (whatever contest) then the next
contest is introduced. ]

[After all the contests have been covered, were in confirmation/correction
mode. At this point, the voter can print the ballot after hearing all the
selections read back or can go back to change]

Please listen to the selections you have made. [read selections like with
bva]. If the ballot is the way you want it, hit the down arrow to print.
If you want to make changes, hit the right arrow or the left arrow to go to
the contest you want to change.

Comments please.
