Augmented reality app helps libraries keep track of books

Library books that have been shelved incorrectly are a constant cause of frustration for those searching for a specific text, and rearranging them is constant chore for library staff. Hoping to make the task a little easier for librarians everywhere, ShelvAR is an augmented reality app for Android devices that’s designed to help library workers scan books to identify and re-shelve those that were put in the wrong spot.
