🤖 AI Summary
This study addresses the lack of domain-specific usability evaluation guidelines and systematic analytical tools for configurator user interfaces, which has led to inefficient and insufficiently expert assessments. To bridge this gap, the work proposes a semi-automated evaluation framework that leverages multimodal large language models (MLLMs) to jointly reason over visual and textual inputs. Grounded in 18 configurator-specific usability criteria, the framework automatically identifies usability issues, rates their severity, and generates actionable improvement suggestions. Experimental validation on 16 real-world configurators demonstrates that the approach reliably and efficiently diagnoses configurator-unique usability problems, substantially reducing manual effort while exhibiting strong scalability and adaptability across domains.
📝 Abstract
Configuration is a key technology for tailoring complex software systems, services, and products. A successful application of configurators not only depends on technical correctness, performance, and domain modeling but also on their usability. While general usability heuristics are widely used, configurator-specific criteria and tool support for systematic user interface (UI) analysis are limited. This paper explores the use of multimodal large language models (MLLMs) for scalable and semi-automated usability analysis of configurator UIs. We synthesize 18 configurator-specific usability criteria from the literature and apply these criteria in an MLLM-based analysis of 16 real-world configurators. Each criterion is assessed individually to generate severity ratings for usability issues and actionable improvement suggestions. A review of the results confirms that MLLMs can reliably identify configurator-specific usability issues and provide domain-aware improvement recommendations. Although human validation remains necessary, this approach has the potential to significantly reduce the required effort to analyze configurator usability.
