Because images are sometimes better than a thousand words, Yvonne Jansen, formerly a researcher at ISIR, uses situated data visualization to facilitate learning and decision making in our daily lives. The researcher in human-computer interaction was awarded the bronze medal of the CNRS for her work.
Many of our daily decisions are based on data that are more or less accessible and easy to understand. The objective of Yvonne Jansen’s research, a CNRS researcher at the Bordelais Computer Science Research Laboratory, is to facilitate their understanding thanks to tools that allow us to represent and interact with the information around us through situated visualization.
She first devoted herself to researching new modes of human-computer interaction before moving on to concrete applications. Her first contributions to ISIR, with her doctoral student Clara Rigaud, were in the area of sharing and learning environments: Fab Labs. Her goal: to determine the best way to capture data in a manufacturing workshop. Each machine – ranging from 3D printers to milling machines – captures experiences and sends recommendations back to the person using it. “This device theoretically reduced the amount of trial and error that leads people to the right options through feedback from previous experiences,” Yvonne Jansen explains.
Yvonne Jansen’s work aims at facilitating access to data for non-experts through visualizations beyond the classical desktop screens. During her PhD at the University of Paris-Sud she focused on physical visualization techniques (e.g., digitally created histograms). She did her post-doctorate at the University of Copenhagen (Denmark), on the role of the body in human-computer interaction. She is then interested in situated visualizations, which allow to integrate data in the physical environment close to the place or the object they are about. Her research contributes, among other things, to the explanation of climate and energy sobriety issues. Yvonne Jansen designs and studies interactive systems for policy makers and the general public to help them appreciate the data behind everyday decisions, such as the impact of food choices or modes of transportation.
