While augmented reality apps can be pretty flashy and cool to look at, there are only a few I would actually call useful and practical in real life situations. Sure, I can pan my Yelp or Layar apps around to see nearby food locations, kill virtual ghosts, or run away from non-existent zombies, but those are not nearly as meaningful as what a Miami University professor Bo Brinkman has up his sleeve.
The Augmented Reality App for Shelf Reading, developed by Miami University Augmented Reality Research Group (or just MU ARRG - ha!) and headed by Bo, will have librarians salivating over its potentially time-saving capabilities. Watch Bo demonstrate the app's near-instant detection of out-of-order books on a shelf, followed by an on-screen shortest path algorithm to return misplaced books back to their locations. The icing on the cake - instant inventory of whole bookshelves, which would likely save hours of time per week for a typical librarian.
Now that is truly useful. Bravo, MU ARRG (I just can't stop saying it):
