Topic overview
This PhD position is part of a joint Franco-German project. The PhD student will study very small data visualizations, micro visualizations, in display contexts that can only dedicate minimal rendering space for data representations. The increasing demand for data visualizations on small mobile devices such as fitness tracking armbands, smart watches, or mobile phones drives this research direction. Given this usage context, the goal is to focus on situations in which visualizations are used “on the go,” while walking, riding a vehicle, or running.
Research Goals
It is still unclear to which extent our knowledge of desktop-sized visualizations transfers to contexts that involve minimal display space, diverse viewing angles, and moving displays. We want to understand how visualizations can be read when they are worn on a person. Do certain types of visualization support better reading when people just briefly glance at them - or when their hands or arms are shaking (e.g. while jogging or moving in a vehicle)?
Impact
Our focus on small or moving displays is novel and timely while supporting realistic usage scenarios. Ultimately, this research direction aims to empower people to use visualizations outside a typical work environment furthering the research agenda of “beyond-the-desktop” visualizations. Example usage scenarios include fitness tracking armbands showing step counts or heart rates, hand-held GPS trackers showing elevation profiles, or mobile phone visualizations used in emergency response scenarios.
In summary, we aim at paving the way for a pervasive use of visualizations and thus a better and broader understanding of the complex world around us.
Related Work
This proposal builds on and expands two existing research streams: data glyphs, which focus on studying data representations of multi-attribute dimensions, and word-scale visualizations such as sparklines, which focus on small visualizations embedded in text-documents. In this project, we consider these types of small visualizations together under the umbrella of “micro visualizations.” Specifically, we define micro visualizations as small-scale visualizations that lack or have a limited set of reference structures such as labels, data axes, or grid lines and have a small physical footprint of a few square centimeters. Micro visualizations can be as simple as small unit-based visualizations such as a battery indicator but also include multi-dimensional visualizations such as star glyphs, small geographic visualizations or even small network visualizations. 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 in interpreting micro visualizations.
