The increasing demand for data visualizations on small mobile devices such as fitness tracking armbands, smart watches, or mobile phones motivates my past work on the design and perception of very small micro visualizations. Micro visualizations are very small data visualizations that can only dedicate minimal rendering space for data representations and, thus, often reference structures such as labels, axes, or grid lines. Although micro visualizations are essential to mobile visualization contexts, we know surprisingly little about their general visual and interaction design space or people’s ability to interpret them. In this talk I will give an overview of my joint past work in the area of micro-visualizations and give an outlook on how they can help to enable a more pervasive use of visual data representation.


Petra Isenberg Petra Isenberg is a research scientist (CR1) at Inria, Saclay, France in the Aviz research group. Prior to joining Inria, Petra received her PhD from the University of Calgary in 2009 and her Diplom-degree in Computational Visualistics from the University of Magdeburg in 2004. Her main research areas are information visualization and visual analytics with a focus on collaborative work scenarios, interaction, and evaluation. She is interested in exploring how people can most effectively work together when analyzing large and complex data sets on novel display technology such as small touch-screens, wall displays, or tabletops.
