Re: Ang: AT for LD

Hi Peter,

You and I discussed this on the phone once as well.

I think Orca magnification as well as its interpretation of AT-SPI information could do a lot here. We need other visual effects: changing colors, stretching text, adding extra whitespace, etc. But this, for the most art, seems to exist in graphics libraries.

I'm not the guy to do this project, it's way too visual. I've just known so many people for whom a "professional" solution for people with non-blindness print disorders.

I have a bunch of ideas collected from my days at FS and would work with others to help as I can.

Happy Hacking,

As Mats may recall (from conversations about this in AEGIS meetings), I have also long been interested in seeing such an app.  I personally believe that the foundational work supporting GNOME Shell Magnifier is the right place to start such an effort.  Much of what you would like to offer someone with LD is highlighting of various parts of the UI.  Also potentially stripping parts of the UI away that get in the way.  A research project called UI Façades (see and the paper at gives a sense of what is possible when you own the window manager, have X Composite & OpenGL, and leverage AT-SPI.

I personally hope developing something like this could be done in the context of a significant, funded research project.

cdh: I agree entirely. THe idea I had was to start an entirely new
project but use parts of Orca where such would be convenient.
Joanie: Is there a danger of depending on Orca for this support? I fear there
be. Perhaps the thing to do instead is identify the needs which are in
common, and develop a separate library or tool which Orca and this new
LD tool under consideration could each use (should they see fit to do

cdh: I'm just tossing this idea around now. I have discussed it with some friends but how the engineering would work is way off in the future.

cdh: My idea is to provide an interface like KESI has in K3000 but instead of doing everything in one unified ghetto app, add the augmentations on the screen with information derived from AT-SPI. 

cdh: This will need to be a highly graphical piece of software so I'm not likely the right person for the gig but I've studied the problem and have a bunch of ideas for people with print impairments in the workplace.
