Chromatic Aberration

Effect of Lateral Chromatic Aberration for Chart Reading in Information Visualization on Display Devices

Kyle Koh, Bohyoung Kim, and Jinwook Seo / 2014

Motivation

We examine the effect of lateral chromatic aberration (LCA) when reading information displayed on the screen and how it leads to misinterpretation of charts and values represented. Although the effect can be observed from natural scenes, we focus on LCA on modern displays. We present a result from a user study to observe the effect on users’ judgment when reading charts on displays. We also introduce a prototype software-based correction method with promising results. Lastly, we suggest guidelines for information visualization designers to avoid the issues.
