Abstract
How do people interact with computers? This fundamental question was asked by Card, Moran and Newell in 1983 with a proposition to frame it as a question about human cognition, in other words as a question of how information is processed in the mind. Recently, the question has been reframed as a question of adaptation: how do people adapt interaction to the limits imposed by cognition, device design and its environment? We synthesize advances in answering this question under the theoretical framework
of computational rationality. The core assumption is that users act according to what is best for them given the limits imposed by their cognitive architecture and their experience of the task environment. The theory can be expressed in computational models which explain and predict interaction. We review the theoretical commitments and emerging applications in HCI. We close by outlining challenges for future work.
