No previous message | Next message →
Hello Everyone,
I am working on a use case scenario to test an accessible MAP.
I need your thoughts on it. What are we expecting from an accessible map?
How we usually test an accessible map?
What are the environments? Desktop? Ios? Android?
I'd appreciate any feedback.
Thank you

Hello Shiva,
For visual users, follow WCAG guidelines for contrast, not relying on
colors, and text size.
There is no real good solution yet for nonvisual maps. My masters degree is
in solving this problem, but solutions have not been made scalable yet.
What is the point of the map? Why in the world are you showing a map and
not using text to prove the point?
At the moment, if the answer to the above solution is that the map is just
aesthetic and the information can be, or is already, duplicated in the
text, then I would treat the map as an image and put alt text and duplicate
the image contents in text.
Otherwise the answer gets a bit more complex. If the data that the map is
representing is simple enough to be put into a table, do that.
If it is relational information that is important, such as the list of
points of interest around you, or showing that Sacramento is the capital of
California, then use a menu or list of links.
If the spatial information on the map is extremely important, then you're
going to have to use an experimental solution to make the map nonvisual.
If the map is an overview, like a globe, or showing the location of a
hurricane to the south coast, then I would use a grid system, similar to a
spreadsheet to navigate. There are two options:
1. Use something similar to our prototype at:
https://frastlin.github.io/Nonvisual-Modeling-and-Mapping/globegrid1
2. Make the map into a MUD environment, similar to what you can do
with:
https://github.com/evennia/evennia
We have used both with significant success.
If you are wanting to show users a detailed first-person view, as if they
are walking through the map (like Google street view), then use something
similar to Swamp:
https://audiogames.net/db.php?action=view&id=Swamp
Where you use 3D audio to represent objects, the user can hit objects and
enter objects.
Sorry the spatial methods are so experimental, there is not very much
research on this topic.
If your map is not one of these types, please let me know and I'll see what
other ideas I have for representing it.
Thank you,
