Abstract: User interaction to create clusters and annotate data is crucial in the Visual Interactive Labeling process. In this work we get the feedback from a clinician researcher expert on sleep and activity data analysis, using a basic interactive labeling interface. We study the design of a new interface to improve its usability based on a Voronoi treemap visual metaphor and the Centroidal Voronoi Diagram technique. We propose new interactions to create, move, split and merge groups of items in this framework.
