Previous chapters have addressed a variety of ways in which style can be expressed and evoked—in production, perception, and interaction. The present chapter explores the future of style in interactive applications of artificial intelligence (AI). To do so we dissect style along various dimensions, including functions, levels, domains, and uses, in a survey of current applications and a roadmap for future innovations. We conclude that major advances will require a shift in focus from the function of production to the function of perception—and from the level of semantics to the level of aesthetics.
