Our research currently lies at the intersection of computing, crowdsourcing, and creativity. Since its inception, the field of human-computer interaction has concentrated on developing techniques that enhance productivity. Our work seeks to enhance creativity. Creativity is valued in both the engineering and aesthetic disciplines. We conduct experiments, implement novel systems, and analyze online data sets to contribute to a base of knowledge for improving creative outcomes. Our current work is grounded in the design domains, as these domains are replete with creative activity. Example projects include leveraging online crowds to produce structured feedback on visual designs, studying the iterative design process in open Web platforms, and building interfaces to support consensus building in online design discussions.
