What about ultrasonic obstacle prevent shoes?
I suspect most of us participating in this forum are sighted. Thus, our perspective on what would be useful to the blind may not be very accurate.
Have you visited with blind people or with individuals/agencies that provide services to the blind?
Can you consider projects that might be useful to those with severe visual impairment, but who are not completely blind, such as people with diabetic retinopathy?

Yes, check with actual blind people - look for a forum. We looked into doing a sonic cane one time, only to discover they had been tried before (more than once) and the people they were intended to help didn't like them.
I looked into that a few times. I wanted to make a tactile grid so a person could feel a video picture on their forehead or abdomen. You would want to process the video so that only outlines would be displayed, door frame, chair, etc. Small electrical pulses from a wire mesh won't work because you don't just feel it at the wire intersections. I thought of little solenoids, like from a dot matrix printer or piezo vibrators but any kind of decent resolution would get heavy and sweat would gum up the works. 320 x 240 resolution would require 76800 solenoids or piezo vibrators. Only a robot could wire that thing.
But don't let me stop you. It kept my brain occupied for a while.
Good luck.

I was thinking along the same lines. A audio beep/tone like reverse parking indicators on a car that give you relative distance from an object you are pointing the device at.
I remember a project request long time before here asking for a -distance meter with buzzer integrated onto a walking stick.
