Towards Generation of Visual Attention Map for Source Code

Abstract

Program comprehension is a dominant process in software development and maintenance. Experts are considered to comprehend the source code efficiently by directing their gaze, or attention, to important components in it. However, reflecting the importance of components is still a remaining issue in gaze behavior analysis for source code comprehension. Here we show a conceptual framework to compare the quantified importance of source code components with the gaze behavior of programmers. We use "attention" in attention models (e.g., code2vec) as the importance indices for source code components and evaluate programmers' gaze locations based on the quantified importance. In this report, we introduce the idea of our gaze behavior analysis using the attention map, and the results of a preliminary experiment.

Deep Learning for Head Pose Estimation: A Survey

“…• Interface Design: By perceiving the human attention when they look at an interface (e.g. the page of web or software), it is possible to evaluate the property and significance of the displayed visual elements and further guide the design or rearrangement of these elements [27] (see Fig. 1).…”

Decoding the underlying cognitive processes and related support strategies utilised by expert instructors during source code comprehension

“…This means that the attention may be divided and therefore not fully focused on the current activity. During SCC, expert programmers often focus their attention on complex lines or sections of code (Itoh, 2019). These complex sections of code are likely to contain dynamic representations such as literals, comparisons, operators and keywords (Busjahn et al, 2011).…”
