From data exploration to presentation : designing new systems and interaction techniques to enhance the sense-making process

Abstract : During the last decade, the amount of data has been constantly increasing. These data can come from several sources such as smartphones, audio recorders, cameras, sensors, simulations, and can have various structure. While computers can help us process these data, human judgment and domain expertise is what turns the data into actual knowledge. However, making sense of this increasing amount of diverse data requires visualization and interaction techniques. This thesis contributes such techniques to facilitate data exploration and presentation, during sense-making activities. In the first part of this thesis, we focus on interactive systems and interaction techniques to support sense-making activities. We investigate how users work with diverse content in order to make them able to externalize thoughts through digital annotations. We present our approach with two systems. The first system, ActiveInk enables the natural use of pen for active reading during a data exploration process. Through a qualitative study with eight participants, we contribute observations of active reading behaviors during data exploration and design principles to support sense-making. The second system, SpaceInk, is a design space of pen & touch techniques that make space for in-context annotations during active reading by dynamically reflowing documents. In the second part, we focus on techniques to visually represent insights and answers to questions that arise during sense-making activities. We focus on one of the most elaborate data structures: multivariate networks, that we visualize using a node-link diagram visualization. We investigate how to enable a flexible iterative design process when authoring node-link diagrams for multivariate networks. We first present a system, Graphies, that enables the creation of expressive node-link diagram visualizations by providing designers with a flexible workflow that streamlines the creative process, and effectively supports quick design iterations. Moving beyond the use of static visual variables in node-link diagrams, we investigated the use of motion to encode data attributes. To conclude, we show in this thesis that the sense-making process can be enhanced in both processes of exploration and presentation, by using ink as a new medium to transition between exploration and externalization, and by following a flexible, iterative process to create expressive data representations. The resulting systems establish a research framework where presentation and exploration are a core part of visual data systems.
