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.
They provide a QR+ Navi combination that solves exactly that. When the company goes bankrupt (or gets bought out by Google and shut down), the city can still provide useful information. You can get Navi codes with a fallback URL for non-Navi scanners.
GPS+gyro+camera access can be done by an (archivable) web application as well, but I suppose Navi is incentivised to not offer any non-app fallback so they can charge a subscription for their services.
