Bonjour Mathieu,
Je suis employé STMicroelectronics et malvoyant depuis 2007. Je suis donc potentiellement un utilisateur de vos développements. A ST, Dans le cadre d'un projet Minalogic (Pôle de compétitivité), nous avons travailler à faciliter le déplacement des personnes déficientes visuelles avec le projet Autonomie :
http://autonomie.minalogic.net/
Je me demande si les tablettes android en terme d'accessibilité sont utiles au déficients visuelles. Ma compréhension du lecteur d'écran Android (Talk Back, je crois) n'est pas au niveau de celui d'Apple qui a un grand
succès dans le monde des DV.
Cdlt
Francois

Hi,
We just launch geotablet project (http://sites.google.com/site/geotablet/). The result we will obtain should answer your needs (I hope so [cid:image001.png at 01CCBF3C.79CAAB50] ). May be you could be a tester ?
The way we work is to use the haptimap framework (http://haptimap.org/) in our own application. However starting from navit source code could also be a good idea.
It is the very beginning of the project, every idea interest us.
Thanks for information about "AccessiblityNodeINfo"
Keep in touch.

It occurs to me that this should be fairly easily done on Android 4.0 using its new accessibility APIs, and maybe without any custom plugins for the nav apps.

The key would be making the map view export itself as a hierarchy of AccessibilityNodeInfo objects. One challenge would be dividing all map features, even things like curving roads, into a series of rectangles. You would then create an AccessibilityNodeInfo for each of these rectangles and set a meaningful content description via setContentDescription().
There might need to be a bit of support on the screen reader side, but the result would be a map that works both visually and accessibly.
No time to work on such a project myself, but I'm happy to provide whatever screen reader support I can in Spiel. This would be a neat project.

I would like to have an OSM map accessible for visually impaired users
with a program that makes sounds when you move your finger over the map.
A different sound for the different map items (roads, water and
buildings) and that speaks the names on the map. By moving your finger
over the map you know what is where on the map.
You know where your finger is on the device and you hear what is under
your finger so you can make an image in your mind what is where.
If the map is centered around you (with GPS) you can find out what is
around you and where to go.
You would not need special hardware, just a smart phone with gps and
touchscreen and one that knows its orientation.
By adapting one of the open source programs that use OSM maps (like
Navit) you would not need to completely write a navigation and map
viewing program. You would just need to develop a plugin/module for such
a program to satisfy our needs.
I have also posted the idea in the Navit forum on sourceforge.net<http://sourceforge.net>
http://sourceforge.net/projects/navit/forums/forum/512959
Does anyone have ideas about how to organize and program (write the
code) this?
Thanks,
Robert
