She uses "simply technologies" like mime, gestures and drawings to engage groups and facilitate communication with non-literate populations.
Talking with Debbi, I was reminded of two things:
1. I regularly take for granted the TREMENDOUS opportunity I have to write and teach and be heard by others.
2. Good communication is not about tools it's about CONNECTION and EMPOWERMENT and the successful TRANSFER of KNOWLEDGE from listener to listenee.
It doesn't make a bit of difference how communication is achieved. What matters is that people are seen and heard and valued and that hopefully from this exchange all good things - like improved water systems, better health care, greater access to education, etc. - result.
