Do MLLMs Capture How Interfaces Guide User Behavior? A Benchmark for Multimodal UI/UX Design Understanding

arXiv:2505.05026v5 Announce Type: replace Abstract: User interface (UI) design goes beyond visuals to shape user experience (UX), underscoring the shift toward UI/UX as a unified concept. While recent studies have explored UI evaluation using Multimodal Large Language Models (MLLMs), they largely focus on surface-level features, overlooking how design choices influence user behavior at scale. To fill this gap, we introduce WiserUI-Bench, a novel benchmark for multimodal understanding of how UI/UX design affects user behavior, built on 300 real-world UI image pairs from industry A/B tests, with

Why this matters
Why now

The proliferation of advanced MLLMs and the increasing complexity of digital interfaces necessitate better evaluation methods for UI/UX, pushing for more sophisticated benchmarks.

Why it’s important

This development allows for a more nuanced understanding of how AI can not only design but also interpret the behavioral impact of UI/UX, moving beyond superficial aesthetic evaluation.

What changes

The ability of MLLMs to assess user behavior from UI/UX designs marks a shift towards more intelligent and data-driven interface development, integrating behavioral insights directly into AI design processes.

Winners
  • · AI/ML researchers
  • · Software companies
  • · Product designers
  • · Digital advertisers
Losers
  • · Traditional UI/UX testing firms
  • · Manual A/B testing processes
  • · Inefficient design methodologies
Second-order effects
Direct

MLLMs will become more capable of predicting user interactions and optimizing interface designs for specific behavioral outcomes.

Second

This capability leads to a new generation of AI-driven design tools that autonomously iterate and improve user interfaces based on simulated or real-world behavioral data.

Third

The enhanced efficiency in UI/UX design could accelerate the development and adoption of new digital products and services, further blurring the lines between human and AI design.
