ABSTRACT
Interactive evolutionary design tools enable human intuition and creative decision-making in high-dimensional design domains while leaving technical busywork to the computer. Current evolutionary algorithms for interactive design tools accept only feedback about entire design candidates, not their parts, which can lead to user fatigue. This article describes several case studies in which designers used an enhanced interactive evolutionary design tool with region-of-interest feedback for character animation tasks. This enhanced interactive evolutionary design tool is called the Interactive Design with Evolutionary Algorithms and Sensitivity (IDEAS) tool. Designers’ feedback and narratives about their experiences with the tool show that interactive evolutionary algorithms can be made suitable for the ideation and generation of digital assets, even in time-varying domains.
