Abstract
Generating meaningful layout of iStar models is a challenging task, which currently requires significant manual efforts. However, it is time-consuming when dealing with large-scale iStar modeling, rising the need of having an automatic iStar layout tool. Previously, we have proposed an algorithm for laying out iStar SD models and have implemented a corresponding prototype tool. In this paper, we report our ongoing empirical work which aims to evaluate the effectiveness and usability of the prototype tool. In particular, we present a research design which is applied to compare manual layout and automatic layout in terms of efficiency and model comprehensibility. Based on such a design, we are planning to carry out empirical studies accordingly in the near future.
