  The interplay between text and visualization is gaining importance for media
where traditional text is enriched by visual elements to improve readability
and emphasize facts. In two controlled eye-tracking experiments ($N=12$), we
approach answers to the question: How do visualization techniques influence
reading behavior? We compare plain text to that marked with highlights, icons,
and word-sized data visualizations. We assess quantitative metrics~(eye
movement, completion time, error rate) and subjective feedback~(personal
preference and ratings). The results indicate that visualization techniques,
especially in the first experiment, show promising trends for improved reading
behavior. The results also show the need for further research to make reading
more effective and inform suggestions for future studies.
