AI BriefingFlowEval: Reference-based Evaluation of Generated User Interfaces (UI)
Key point
We propose FlowEval, a framework that measures whether LLM-generated UIs support natural interaction flows like real websites.
Details
LLMs and coding agents are widely used for UI development, but reliably evaluating the visual and interaction design capabilities of the interfaces they generate remains a difficult challenge.
Existing evaluation methods have two limitations.
- Human expert evaluation: enables accurate usability measurement but is costly and slow
- Automated Judges: highly scalable but lack accuracy and the evaluation process is opaque
FlowEval is a proposed Reference-based framework designed to address these problems. This framework measures whether a generated UI supports realistic interaction flows by comparing it against Navigation traces from real websites.
