Readability metrics for program code: how is reading ease reflected in gaze?

    Research output: Chapter in Book/Report/Conference proceedingChapter (peer-reviewed)peer-review


    This paper describes a range of models that have been proposed for the readability of program code. We consider ways in which eye movements can be used to provide evidence for the validity of these models. It is proposed that gaze metrics based on fixation count and duration may correlate with readability scores. We also consider the prospects for developing a model based on gaze to measure readability. The usefulness to educators of measures of readability is discussed.
