Automatic updating of a book storage database in a ubiquitous library information system

This article proposes the Augmented Library (AL), which is a library system augmented by ubiquitous computing (UbiComp) technology. In UbiComp, users interact with computers without being aware that they are actually using a computer. We applied the UbiComp concept to a library system. In the AL, the action of removing and returning books, which are the natural actions in a library, become the library system's input. This function is called a "real-time book database update." The system uses a combination of infrared sensors and CCD cameras to identify which book is moved from the shelf. After developing a prototype a prototype system, we conducted experiments that investigated the effectiveness and effectiveness and efficiency of AL.
