ShelvAR consists of an Android app and a set of coded tags, representing call numbers, that are placed on books’ spines. When a librarian holds a smartphone or tablet camera up to a shelf, the app reads all the tags at once, thanks to a new algorithm that can decipher multiple patterns even though they’re small when viewed at a didistance.
Researchers at Miami University have created on 2011 an augmented reality app that makes all those books easier to organize.
