PREVis: Perceived Readability Evaluation for Visualizations
Although readability is recognized as an essential quality of data visualizations, so far there has not been a unified definition of the construct in the context of visual representations. As a result, researchers often lack guidance for determining how to ask people to rate their perceived readability of a visualization. To address this issue, we… Continue reading PREVis: Perceived Readability Evaluation for Visualizations
A cognitive load approach to designing and evaluating data visualizations
Visual representations of data are increasingly prevalent, but we lack a detailed theoretical framework to explain what factors make easy or difficult to read and understand; nor do we know how such factors can impact data visualizations’ efficiency as learning material. In this Master’s Thesis, I address this gap by exploring the validity and applicability… Continue reading A cognitive load approach to designing and evaluating data visualizations
A case to study the relationship between data visualization readability and visualization literacy (position paper)
Only with reliable and relevant measures can we assess how a potential factor affects a reader’s performance; accordingly, only with appropriate measuring instruments can we start to investigate the tight web of interactions between individual characteristics, features of the visual design, and reading tasks requirements. As we slowly progress in our understanding of how people… Continue reading A case to study the relationship between data visualization readability and visualization literacy (position paper)

Pondering the reading of visual representations
We draw from the cognitive psychology literature on models of reading text, and describe a knowledge gap for cognitive processes at work when reading visual representations of data. Access the document on HAL
