Shelfreading is like dusting--no one wants to do it, but it has to be done. Now, however, a new Android app may make shelfreading a breeze. The brainchild of the Miami University Augmented Reality Research Group, the app "'reads' a bookshelf, and with an AR overlay, quickly flags those books that are misplaced. It will also point to the correct place on the bookshelf so the book can easily be re-shelved correctly." This description comes from Audrey Watters' post on the ReadWriteWeb blog. The post includes a video of Professor William "Bo" Brinkman demonstrating how shelfreading would work using the app. Professor Brinkman makes the point that the app won't work well for thin books as they would be difficult to tag. In addition, at the moment the "prototype only uses 16 bits on the tag, but Brinkman says the group is working on a version that would allow them to put around 72 bits on a tag, allowing the system to scale up to work with any library collection." Professor Brinkman says the app would also facilitate doing inventories of library collections. The app will be demonstrated at the ACRL conference on Saturday, April 2.
