There are already devices that allow you to feel vibrations when you are near obstacles. Research the Sunu Band and Buzz Clip.

Nice degree and nice project thought. However, all the commenters thus far have it right. But i won’t be sarcastic i have enough electronics in my body for epilepsy I don’t want electric eyes too. What i would take is something reliable that can scan barcodes, read stuff like my mail, oh and something to help me I’d all those dang cans in the cupboard that i cant find the code on or that aren’t in a database for most barcode readers. Let’s be practical.

Please build me a new functional retina. 😫

How would such a device work? It would need something to detect you are on the correct path, as well as checking for obstacles. Would also need something to check for elevation changes as well as sudden drop-offs (holes or curbs). It would have to reliably detect objects that are mostly empty (chain link fences, rails) but not give too many false positives.

Hmmm, let me brain storm some ideas man.l. I’ll let you know what I come up with and you can tell me if it’s worth my time
