"Computational interaction can be used as an approach to explaining and enhancing the interaction between humans and information technology. It applies abstraction, automation, and analysis to inform our understanding of the structure of interaction and also to inform the design of the software that derives new and exciting human-computer interfaces. Embedded in an iterative design process, computational interaction has the potential to complement human strengths and provide methods for generating inspiring and elegant designs."
