Pulling Strings from a Tangle: Visualizing a Personal Music Listening History
In Proceedings of the 14th International Conference on Intelligent User Interfaces (IUI 2009), Sanibel Island, USA, Feb. 2009 (bib)

The history of songs, to which a person has listened, is a very personal piece of information. It is a rich data set that comes as a byproduct of the use of digital music players and can be obtained without interfering with the user. In this paper, we present three visualizations for this data set and a mechanism for generating new playlists from the users own listening history, based on a navigation metaphor. First, temporal proximity is interpreted as a simple similarity measure to lay out the entire history on a two-dimensional plane. Closed listening sessions are then used to make chronological relations visible. The generated playlists mimic the users previous listening behavior, and the visualizations make the automatic choices understandable, as they share visual properties with the history. In this sense, our visualizations provide a visual vocabulary for listening behaviors and bring scrutability to automatic playlist generation.
