The AI of Oz: A Conceptual Framework for Democratizing Generative AI in Live-Prototyping User Studies

Commonly used methods in User-Centered Design (UCD) can face challenges in incorporating user feedback during early design stages, often resulting in extended iteration cycles. To address this, we explore the following question: “How can generative artificial intelligence (AI) be utilized to enable prototyping within user studies to facilitate immediate user feedback integration and validation?” We introduce a conceptual framework for live-prototyping, where designers modify AI-generated components of a prototype in real time through a separate control interface during user testing. This approach invites more immediate interaction between feedback and design decisions. To explore our concept, we engaged in a case study with experienced prototyping practitioners, examining how real-time prototyping might shape design processes. Participants highlighted the framework’s potential to support spontaneous insight generation and enhance collaborative dynamics. However, they also highlighted important considerations, including the need for a certain level of AI knowledge and challenges around planning and reliability. By integrating generative AI into the UCD process, our conceptual framework contributes to ongoing conversations around evolving user-centered methodologies.
