I saw this on my breakfast cereal box (in the US) and looked it up. A company called Navilens made this to help visually impaired people with things like street signs, etc... neat!
EDIT TO ADD: Haha, I forgot I am on lemmy so we're discussing the technology and licensing issues, instead of focusing on how this might improve the lives of visually impaired people.
Yeah but no. I think, in a way, they're having your phone's camera assist you if you can't see well.
Yeah, it looks like it's both more detailed navigation for sighted people, and geared towards helping people with difficulty seeing.
Wish it didn't look like to be a proprietary code format, since that severely limits it's viability as a widespread thing.
