Ruth Rosenholtz - Do predictions of visual perception aid design?
Understanding and exploiting the abilities of the human visual system is an important part of the design of usable user interfaces and information visualizations. Designers traditionally learn qualitative rules-of-thumb for how to enable quick, easy and veridical perception of their design. More recently, work in human and computer vision, including in our lab, has produced more quantitative models of human perception. These models often take as input arbitrary, complex images of a design. We ask whether such models aid the design process. Through a series of interactions with designers and design teams, we find that the models can help, but in somewhat unexpected ways. Based on this study, I will suggest general design principles for perceptual tools.
