| Abstract | Motivation: Software visualization can be helpful in comprehending the architecture of large software systems. Traditionally, software visualisation focuses on representing the structural perspectives of systems. In this paper we enrich this perspective by adding the notion of role-stereotype. This rolestereotype carries information about the type of functionality that a class has in the system as well as the types of collaborations with other classes that it typically has.Objective: We propose an interactive visualization called RoleViz, that visualizes system architectures in which architectural elements are annotated with their role-stereotypes.Method: We conducted a user-study in which developers use RoleViz and Softagram (a commercial tool for software architecture comprehension) to solve two separate comprehension tasks on a large open source system. We compared RoleViz against Softagram in terms of participant's: (i) perceived cognitive load, (ii) perceived usability, and (iii) understanding of the system. Result: In total, 16 developers participated in our study. Six of the participants explicitly indicated that visualizing roles helped them complete the assigned tasks. Our observations indicate significant differences in terms of participant's perceived usability and understanding scores.Conclusion: The participants achieved better scores on completing software understanding tasks with RoleViz without any cognitive-load penalty.Demo: https://youtu.be/HqCUAlai4qw?t=258 |
