Title: Towards a Cognitive Model of Feature Model Comprehension: An Exploratory Study using Eye-Tracking. Authors: Elmira Rezaei Sepasi, Kambiz Nezami Balouchi, Julien Mercier, and Roberto Erick Lopez-Herrejon. Abstract:Feature models are pivotal components of Software Product Lines. Therefore, their correct comprehension is crucial for performing adequately all the tasks where they are involved. Despite their importance, to the best of our knowledge, no research has been done on feature model comprehension. As a first step to address this lack, our work contributes an empirical study of feature model comprehension in simple configuration validation tasks. We propose a first cognitive model for this type of tasks that we analyze by measuring eye gaze fixations on the different visual elements involved in the tasks. Our results identified three main components of the cognitive model and their distribution in terms of the cognitive effort for performing these tasks. We argue that further research on feature model comprehension can inform language design and tool development to provide more suitable language structures, user interfaces and support for this kind of models.

JSS An Empirical Eye-Tracker Study of Visualization Techniques for Coverage of Combinatorial Interaction Testing in Software Product Lines
Borealis
Lopez Herrejon, Roberto Erick; Nezami Balouchi, Kambiz — 2024-02-09 Software Product Lines (SPLs) typically provide a large number of configurations to cater to a set of diverse requirements of specific markets. This large number of configurations renders unfeasible to test them all individually. Instead, Combinatorial Interaction Testing (CIT) compute a representative sample according to criteria of the interactions of feature in the configurations. We performed an empirical study using task performance an eye-tracker technologies to analyze the effectiveness of two visualization techniques at conveying the test coverage of ten case studies of varying complexity. Our evaluation considered accuracy, execution time, metacognitive monitoring, and visual attention. The study revealed clear advantages of a visualization technique over the other in three evaluation aspects, with a reverse effect depending on the strength of the coverage and distinct areas of visual attention.
