Efficient Personalization of Generative User Interfaces

The paper "Efficient Personalization of Generative User Interfaces" addresses the challenge of tailoring generative user interfaces (GenUIs) to individual users when interface screens are not pre‑defined. By collecting judgments from 20 participants on 600 GenUI pairs, the authors show low agreement (Krippendorff's alpha = 0.25) and diverse rationales for UI preferences. They propose a sample‑efficient personalization method that leverages a few pairwise judgments to weight prior users’ preferences, outperforming a pretrained UI evaluator and a larger multimodal model offline and outperforming all baselines in an online study with 12 new users. "whyItMatters":"The study demonstrates a practical approach to personalizing on‑demand interfaces, showing that even sparse, subjective feedback can be effectively used to improve user satisfaction with generative UI designs."
