What is the most relevant legacy by Turing for epistemology of Artificial Intelligence (AI) and cognitive science? Of course, we could see it in the ideas set out in his well-known article of 1950, Computing Machinery and Intelligence. But how could his imitation game, and its following evolution in what we know as Turing Test, still be so relevant? What we want to argue is that the nature of imitation game as a method for evaluating research on intelligent artifacts, has not its core specifically in (natural) language capability as a way of showing the presence of intelligence in a certain entity, but in the interaction between human being and machines. Human-computer interaction is a particular field in information science for many import...
