An Eye Tracking Study on Text Customization for User Performance and Preference

This paper presents a user study which compares reading performance versus user preference in customization of the text. We study the following parameters: grey scales for the font and the background, colors combinations, font size, column width and spacing of characters, lines and paragraphs. We used eye tracking to measure the reading performance of 92 participants, and questionnaires to collect their preferences. The study shows correlations on larger contrast and sizes, but there is no concluding evidence for the other parameters. Based on our results, we propose a set of text customization guidelines for reading text on screen combining the results of both kind of data.
