This is one of my first augmented reality projects that I created in Unity 3D. The app replaces the cover of several books with an overlay that has key information about the book (title, author, publisher, copyright year, and ISBN).
At a large scale, an app like this has the potential of making it much easier for librarians and library patrons alike to get key information about their books without even having to open the cover.
This project also reinforced how excellent augmented reality is for presenting additional information about a target at a glance.
I used Unity 3D and Vuforia to track the image targets and present the overlays.
If you think that you may need an augmented reality app to help improve human performance at your organization, please contact me.
