Abstract
To establish a harmonic interaction between a human and a computer, we reconsider human interactions that establish natural communication. Instead of investigating verbal communication, we use the simple and low-level environment where inputs and outputs of subjects are restricted in a low dimension at the behavioral level. Our final goal is to clarify with the simple environment how humans can create human-like interaction such as an interaction that produces the feeling of human. To achieve it, behavior-based turing-test is proposed here. As a result, it is shown that the emergence of turn-taking behavior plays an important role to pass our behavior-based turing test. The results are also discussed with the attractor superimposition.
