This blog post showed up in my Google Reader. It is about QR codes, the ones that you can get an app for your phone and scan bar codes and it will give you information. I have only thought of this being used with food at the grocery store and it never occurred to me that they could be used as Assistive Technology!
If anyone is still looking for more groups to join, I have been informed by Jeremy (the creator of the group) to join Assistive Technnology (yes I know it has two n's) which is a group on Facebook. http://www.facebook.com/groups/125241767530963?ap=1
