We have concocted a Phototelling assignment that encourages the student to see their own neighborhood with new eyes and then to share that experience with their classmates. What will we ask of the creative and sharing student that can't see?
We have a version of Phototelling for the student that doesn’t own a smartphone. See Geocoding Street View
Can we invent a variation for the kid that can’t see?
I had a blind colleague who explained to me once how he could stay on a straight course walking across a parking lot by feeling the sun on his skin. This is “seeing” that I don’t know how to share with fellow students in a wiki.
I can imagine spending a weekend recording the ambient sounds in a neighborhood. How could that be shared with sighted peers such that they become more aware of what they hear?
Binaural for sound is like color for pictures. Listen to a Wonderful Place in Italy. audio 
Perhaps we could develop a workflow where sounds fill a page. We would want this to be "sounds first" but could see some visual augmentation added later for the benefit of less aurally sensitive students.

Wouldn’t it be great if a smartphone with three cameras also had two microphones?
Aside: Back in the days of portable cassette recorders I had one that had a stereo microphone. I could record a conversation in a room full of chatter and hear everything said clearly so long as I put on my headphones.
