Would anyone be interested in a cane that could sense things further away?

Hello!
My first post, so sry if im doing something wrong.

So last year, i got an inflammation in my eyes, im now back to almost normal, but for a while i was almost blind. It got me thinking of ways i would be able to adapt to the world in case i never got my sight back.

I have a background in electrical engineering and i now work as a developer in the field of small embedded IoT devices. I dont know if this thing already exists, but i had this thought that i could make a cane attachment that you put on the cane or just a short cane, that would then send out a sonar ping to see how far away the thing you are pointing the cane at is and vibrate the cane with different intensity depending on how close it would be. I could imagine myself getting good with such a device and be able to "see" the world around me by swinging it back and fourth.

But i dont know, and i dont need it anymore, so im asking you guys what you thing about the idea?
