Tree-Based versus Hybrid Graphical-Textual Model Editors: An Empirical Study of Testing Specifications
arxiv(2024)
摘要
Tree-based model editors and hybrid graphical-textual model editors have
advantages and limitations when editing domain models. Data is displayed
hierarchically in tree-based model editors, whereas hybrid graphical-textual
model editors capture high-level domain concepts graphically and low-level
domain details textually. We conducted an empirical user study with 22
participants, to evaluate the implicit assumption of system modellers that
hybrid notations are superior, and to investigate the tradeoffs between
tree-based and hybrid model editors. The results of the user study indicate
that users largely prefer hybrid editors and are more confident with hybrid
notations for understanding the meaning of conditions. Furthermore, we found
that tree editors provide superior performance for analysing ordered lists of
model elements, whereas activities requiring the comprehension or modelling of
complex conditions are carried out faster through a hybrid editor.
