"Using image-matching algorithms the researchers have found a way to adorn the real world with digital content."
When I saw the headline, I assumed they were doing something slightly different...
Cheap cameras are sensitive to IR light, so using an IR scanning laser you could project stuff that was visible to cameras but not to the naked eye.
(I don't know if mobile phone cameras typically have IR filters or not, though, so this might not actually work...)
