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.
Using AR features as assistive tech (navigation, visual inference, etc) for the blind and visually impaired was the focus of most of my publishing up until a few years ago. I expect you’ll see more of this type of stuff moving forward, including codes like this and hidden calibration markers for indoor spatial orientation and object interaction.
