A propos du centre ou de la direction fonctionnelle

Located at the heart of the main national research and higher education cluster, member of the Université Paris Saclay, a major actor in the French Investments for the Future Programme (Idex, LabEx, IRT, Equipex) and partner of the main establishments present on the plateau, the centre is particularly active in three major areas: data and knowledge; safety, security and reliability; modelling, simulation and optimisation (with priority given to energy).   

The 500 researchers and engineers from Inria and its partners who work in the research centre's 30 teams, the 60 research support staff members, the high-level equipment at their disposal (image walls, high-performance computing clusters, sensor networks), and the privileged relationships with prestigious industrial partners, all make Inria Saclay Île-de-France a key research centre in the local landscape and one that is oriented towards Europe and the world.

Contexte et atouts du poste

The thesis is fully funded by Inria and the ANR project GLACIS, which brings together experts from Human-Computer Interaction (HCI), Information Visualization, and Computer Graphics. There are opportunities for collaboration with Inria Sophia Antipolis (Computer Graphics), as well as Inria Bordeaux, the École Centrale de Lyon, and the University of Toronto (Visualization and HCI). We also foresee close interactions with design experts.

Mission confiée

Context

Professionals commonly switch between sketches on paper and computers to reach a new data visualization design [Landers and Heller, 2014]. Computer programs are powerful tools that allow professionals to generate solutions keeping a direct binding with the underlying data. But many expert designers first start by exploring visualization solutions through hand-drawn sketches. Before having access to the actual data, sketches enable them to “visualize the architecture of the infographics and cultivate ideas for shaping the data visually,” while later, sketching with data can “help raise new questions about the data itself” [Lupi, 2015].

Unfortunately, dominant visualization systems target data-exploration and data-analysis tasks and fail to meet communication purposes [Kosara, 2016]. Previous studies [Bigelow, 2014] also suggest that current visualization tools impose a data-to-graphics workflow that hinders visual thinking. As a result, the process of creating an original infographic can be extremely manual, involving multiple tools that are largely disconnected from the underlying data. In contrast, we aim to address the more ambitious goal of computer-aided design that treats infographic creation as a visual-thinking process [Ware, 2008]. This process is driven by the graphics, starting from sketches, moving to flexible graphical structures that embed constraints, and ending with data and generative parametric instructions, which can then re-feed the designer’s sketches and graphics.

Principales activités

Objectives

The key objectives of the PhD thesis are as follows:

  1. Devise a grammar of expressive visualization graphics that accommodate flexible and organic sketch-based representations.
  2. Establish a set of sketching operators that can express representative workflows for constructing creative visualizations through sketching.
  3. Design sketch-based user interface techniques for data illustrators or visualization designers that turn sketches into organic, generative elements of a design solution.

The work will build upon a very activate research on visualization authoring tools [Kim et al., 2017; Ren et al., 2019; Tsandilas, 2021], sketching user interfaces [Tsandilas et al., 2015, Xia et al., 2018], visualization grammars [Satyanarayan, 2017], approaches for synthesizing diagrams [Ye et al., 2020], and shape grammars [Stiny, 2006].
