The comment on the change is:
== Use cases ==
+ * Astrid, who has red-green colour blindness has trouble extracting date fra charts where both these colours are used. A filter changing greens to blue would help.
== Scope ==
+ Add filtering capability to gnome-mag (now available upstream). Add configuration settings to gnome-orca.
== Design ==
- Add a filtering feature to gnome-mag. This allows us to take advantage of other powerful features such as probing of the desktop via AT-SPI and filtering combined with zoom.
+ Add a filtering feature to gnome-mag enhance the contrast of the entire display. This will be similar to what is currently done with the 'Invert' option in gnome-mag, though many users of the new feature will simply run gnome-mag at zoom level 1.
- In the design of the interface for this, that must go in Orca or Gnopernicus, the references pointed in http://mail.gnome.org/archives/gnome-accessibility-list/2006-October/msg00074.html is a good source of informations.
+ Using an AT-SPI application (gnome-mag) as our base also allows us to take advantage of other powerful features in later stages such as probing of the desktop via AT-SPI to alter only selected ares such as charts with poor contrast. Filtering combined with zoom will be available from the start.
+ Add a configuration tool to Orca to apply settings to the colour filter.
== Implementation ==
- An initial implementation using [http://people.debian.org/~ruoso/libcolorblind-0.0.0.tgz libcolorblind] was done for gnome-mag and can be verified in http://bugzilla.gnome.org/show_bug.cgi?id=377856
+ An initial implementation using [http://people.debian.org/~ruoso/libcolorblind-0.0.0.tgz libcolorblind] was done for gnome-mag. See patches in the [http://bugzilla.gnome.org/show_bug.cgi?id=377856 gnome-bugzilla].
- === Code ===
+ Configuration tools should be developed with upstream (Gnome and Orca).
- == Unresolved issues ==
+ == Reference ==
- == BoF agenda and discussion ==
+ [http://mail.gnome.org/archives/gnome-accessibility-list/2006-October/msg00074.html Several links to assistive applications for colour blindness].
