Man I miss Microsoft Soundscape (https://www.microsoft.com/en-us/research/product/soundscape/), although it has been open-sourced.
As visually-impaired I can't really make use of stuff like street signs that much. I mean, I _can_, but I have to be really conscious about it and I've never really gotten good at it. With Soundscape, you'd wear earbuds and it'd read you out the street names as you were approaching them, but the street names would be read out from the correct direction using spatial audio that was also head tracked.
So for the first time I felt like I could start using way more cues to build that map in my head. Unfortunately I discovered it far too late because about a year (I think) after I started using it, it was discontinued. Would love to see a fully device-local version of something like this.
