Yes, I think the difference between facialvision and echolocation is the emanation of clicks that are picked up auditory, whereas, Facial Vision is a sensation of nearby objects picked up by the facial nerves. That is the medically accepted definition in the Stedman's Medical Dictionary. I doubt that echolocation works for the deaf-blind; whereas they do exhibit facial vision.

Others on that list have talked about facial vision.

I don't know when it is on your local stations; but it is on WUOM-91.7 tonight at 8:00 EST January 26. It can be heard on their website as well, michiganradio.org.
