Sounds like this could have been a place where we posted out game in development, for teaching social skills through gaming to young adults with autism, ADHD, or cochlear implants (and conditions similar to these).
Hi, Sally, I reached out to you on Facebook. On the OpenIDEO post, I pinged one of the martial artists I know who is most engaged in fall prevention work. You might want to also check out what MedlinePlus has on this: https://medlineplus.gov/falls.html (and there is more). I do not work with any of these teams or projects. It's just that I'm a medical librarian and I know how to find this stuff! I have mixed feelings about volunteering to be on another team, because right now I'm injured and suffering from having overcommitted before getting injured. I can help with little informational searches like these, though.
Your ideas on how tor each people in their community are solid. This is similar to how public health reaches out around important health issues. There are some wonderful resources at the Stop Falls website: http://stopfalls.org/ and the National Council on Aging. https://www.ncoa.org/healthy-aging/falls-prevention/ as well as NIH, CDC, AAOS, NOF, and others. Most of these are free and free to share. McKnights has a new articles on using virtual reality for fall prevention. http://www.mcknightsseniorliving.com/news/falls-prevention-may-be-aided-by-virtual-reality-in-the-future/article/652316/ There is also a lot of work going on with using martial arts for this.
