An Empirical Study on the Patterns of Eye Movement during Summarization Tasks

摘要

Eye movement patterns are the order in which keywords or sections of keywords are read. These patterns are an important component of how programmers read source code. One strategy for determining how programmers perform summarization tasks is through eye tracking studies. These studies examine where people focus their attention while viewing text or images. In this study, we expand on eye tracking analysis to determine the eye movement patterns of programmers. We begin the study with a qualitative exploration of the eye movement patterns used by 10 professional programmers from an earlier study. We then use what we learned qualitatively to perform a quantitative analysis of those patterns. We found that all ten of the programmers followed nearly identical eye movement patterns. These patterns were analogous to eye movement patterns of reading natural language.
