Blind people could benefit of carrying one or several ultrasonic sensor like those used on cars to park. That would emit soft bleeps, faster when something is on the way or closer to an obstacle.
Can be built easily with an Arduino
I think that another possibility could be to fill your home or workplace with those devices put on walls or furniture. The idea would be that your table could say to you "lookout, I'm here" when you are about to crash against it. Use it first in the areas that were more problematic. The volume of the bleeps should be reduced to a low comfortable whispering level so they don't annoy the user. I wonder why nobody has created still a kitt providing a soundscape for blind people. That product should have a different click sound for each object marked in the soundscape.
Another possibility would be a snapshot soundscape, where a remote control could turn on/off the system only when necessary providing the blind people with a mental picture hearing all the blips at the same time and its position respect to the other blips. Like a cane, but covering much more distance
Hum, that last idea deserve more time
I want to propose this system. Imagine that you are on a workplace where blind people came often to work or as clients. There is a soft, low, slow and sparse music that is pleasing to hear as a background for anybody and is always changing.
Now lets imagine that this music is codified and played on a 3D system.
Every time we hear a piano note it means "door here", all bass notes mean "danger/stairs" and a flute means for example "WC". That would be awesome for blind people navigating new places without interrupting other workers asking for directions. Each one of this signals would be played on intervals of one minute or more, never less, so most of the time you have either silence or pleasant sounds that don't bother other people and the notes played by a particular instrument are changed each time for the same reason.
If we need more information, we could add short cords from popular music to convey additional words. For example a <garage door> could play on piano the four note sequence "here on my car" from Gary Numan, or iterate over a list of similar parts of very popular songs with the word "car" on it to not be too repetitive.
Of course it just could also just say "garage door" when a modified white cane approach like on elevators, but that could be distracting for non blind workers.
