blind assist needs both tui and aui

11.23: adde/blind assist needs both tui and aui:

. many softwares don't have an audio user interface (aui)

so the blind typically employ their own screen scraper

to convert gui to aui .

. there is some advantage to adde having a dedicated aui,

but in case people want to user their own screen scraper,

there should also be a mode that presents a

textual user interface (tui) .

. this means translating even graphical concepts

into the sort of text that makes sense being verbalized .

. one of the first problems is

how to intuitively read a table:

. in a table you'd give dimensions;

then choices about how the table is read:

eg row i loop contents;

eg, row i loop col j contents;

eg, row-col i,j: cell contents .

. they can be made aware of customizable orderings:

can hand-switch col' order before proceeding;

can order a row as ascending or descending; etc .

. an intelligence plug-in should provide

trends in table data .

. all native d'types have a visual representation

that is text

and can have also have a separate audio representation

for when the text is an abbreviation

or some other non-word

that a screen scraper couldn't figure how to say .
