Reframing Cultural Heritage Collections in a Visualization Framework of Space-Time Cubes

During the last decades, digitization broadened access to cultural heritage collections for public audiences. Large online databases have been prepared for open access with simple search interfaces or visual exploration methods. In this position paper we discuss new challenges arising from these initiatives with regard to casual users. To meet their specific needs, we introduce a novel method for synoptic collection visualization which makes use of parallel space-time cubes to provide multiple spatiotemporal overviews, support free exploration, and to specifically engage casual audiences.
