The 24-25 October UDC has organized its Seminar at the National Library in The Hague, Netherlands, whose topic is the visualization and interaction with classifications. Since the subject is largely interdisciplinary, the people who are going to attend have different expertises: Library and Information Science, Information Visualization, Digital Humanities, Computer Science, Psychology, Design, etc. This is the first time I see libraries specialists opening so widely their opportunities of collaboration.
For this occasion I will present a paper written with the help of my former professor Giorgio De Michelis. The argument is simple: it regards two paradigms to navigate and manage classifications on tablet computers. The first is based on lists: they can be scrolled vertically or swiped horizontally by page. Usually these two interactions are separated, I propose a way to use both at the same time. The second treats the idea to manage classifications using a two-columns interface. Each column is a representation of one classification, this means that two instances of the same classification are shown simultaneously. The value is evident, if you want to make a relation between two subjects you can see them in their contexts at the same time. But this is not the only advantage, imagine this with two or three classifications or simply read the pre-printed version of the paper here for free.
