Communication Boards are widely used by individuals who are non-verbal to help them express themselves.  It consists of symbols that a user can drag onto the sentence form field or point to or blink at with someone’s assistance.  This is a companion app to EmberApp, a disability emergency preparedness app.  This can be used not only by individuals with a disability such as autism or a speech impairment, but even by those that are not able to communicate due to oral injuries during emergency situations.
