This paper presents SongExplorer, a system for the exploration of large music collections on tabletop interfaces. SongExplorer addresses the problem of finding new interesting songs on large music databases, from an interaction design perspective. Using high level descriptors of musical songs, SongExplorer creates a coherent 2D map based on similarity, in(More)
While the HCI community has been putting a lot of effort on creating physical interfaces for collaboration, studying multi-user interaction dynamics and creating specific applications to support (and test) this kind of phenomena, it has not addressed the problems implied in having multiple applications sharing the same interactive space. Having an ecology(More)
In the past decade we have seen a growing presence of table-top systems applied to music, lately with even some products becoming commercially available and being used by professional musicians in concerts. The development of this type of applications requires several demanding technical expertises such as input processing, graphical design, real time sound(More)
Interaction designers often use machine learning tools to generate intuitive mappings between complex inputs and outputs. These tools are usually trained live, which is not always feasible or practical. We combine RepoVizz, an online repository and visualizer for multimodal data, with a suite of Interactive Machine Learning tools, to demonstrate a technical(More)
Multi-touch technologies have been increasing its popularity in the last decade. Nowadays we can find a plethora of devices that includes this technology: tablets, smartphones or even in desktop computers. In parallel tangible tabletop surfaces started to appear in the global market with devices such as Reactable. What all this devices have in common is its(More)
Tangible interactions on horizontal surfaces are increasingly relevant for collaborative applications, embodied interaction, musical performance, and interaction with 3D information. This unique studio opportunity introduces approaches to developing applications on four related platforms: the Reactable: a musical tabletop, and its companion fiducial(More)
