29 November 2007 Light path indication system for route guidance in public facilities
Author Affiliations +
The authors developed a prototype indication display system for route guidance. We suppose that this system is set up in the public facilities especially a library. A city public library has a collection of many books. It is difficult for a visitor to find the desired book from many books. But we can recently use a library search system for inquiring the whereabouts of a book. The search system outputs a receipt which shows the search result. The destination is shown in this receipt. Though the visitor carries about the receipt during the treasure hunting, that receipt will be a trash after the arrival at his/her destination. The motivation of this research is to build the paperless whereabouts guide system. The guidance system using an electronic display would be possible to provide us with route information to the desired book.
