Abstract: In this article we present a case study on digital representation of the art historical research and metadata brought together for a scientific collection catalogue by the Prussian and Gardens Foundation -. The resulting interface aims at linking the structure and texture of a collection of drawings by Frederick William IV of Prussia (1795–1861) with additional contextual information. The article describes the context of the larger research project and presents the resulting visualization and interaction techniques specifically designed for dynamic exploration along time and subjects. Keywords: information visualization, metadata, zoomable user interface, direct visualization, case study, inventory catalogue, digital art history Link: https://uclab.fh-potsdam.de/fw4/en

The research project »VIKUS - Visualizing Cultural Collections« (Visua­ ­li­ sie­rung kultureller Sammlungen, 2014 - 2017) brings together researchers from various fields such as information visualization, computer science, inter­face design, and the humanities to develop and evaluate graphical inter­faces aimed at enabling interactive examination of cultural objects. The project liaises closely with cultural institutions (e.g., museums, libraries and foundations) as well as with developers of media databases. The VIKUS team approaches the area of digital cultural heritage by combining technological possibilities with cultural considerations in order to develop visualizations and interfaces that open up interesting and useful perspectives on digitized collections. Thereby, novel interaction techniques and representations are designed and evaluated for their suitability for different scenarios.
