Collection Wall Prototype #4 features a Digital Twin of the physical wall, offering an interactive experience that enhances visual navigation and wayfinding. Visitors can explore the Collection Wall by topic or by category—such as study books, recommended readings, student exhibitions, heritage objects, and dissertations—or engage directly with a 2D representation to discover its content. Located in the library hall, the experience is accessible through an interactive kiosk, where users can also scan a book to instantly find its location on the wall or access its online version.
