abstract

We seek to elicit individual design preferences through user-computer interaction. During an iteration of the interactive session, the computer presents a set of designs to the user who then picks any preferred designs from the set. The computer learns from this feedback and creates the next set of designs using its accumulated knowledge to minimize a merit function. Under the hypothesis that user responses are deterministic, we show that an effective query scheme is akin to the Efficient Global Optimization (EGO) algorithm. Using simulated interactions, we discuss how the merit function form and user preference sensitivity can affect search efficiency and hence the time to complete an interactive session. We demonstrate the proposed algorithm in the design of vehicle exteriors.
