There are all sorts of great opportunities for AAC users to build on one another's shoulders, but that can't happen until sharing and collaboration is easy and painless. This is why we built CoughDrop to be both an AAC speech app and also a communication board repository -- to make it easier to share and reuse work that's already been done.
On top of that, we're today releasing an open-licensed file format called .obf (that stands for "Open Board Format"). The idea is to create a file format that doesn't have any usage restrictions and is easy for multiple vendors to implement in their apps. That way we can get past the app-specific limitations and collaborate on interesting and innovation solutions for everyone regardless of what AAC app or device works best for them. Fortunately we're not the only ones that think this is a good idea.
If you're interested in learning more about .obf or want to get involved, check it out at openboardformat.org. Also please spread the word on Facebook, Twitter and everywhere else, and contact your current vendor to ask them about adding support for .obf. Let's keep opening doors!
