Can you communicate with me? - An experimental design how humans regard artificial agents as communication partners

In this paper, we introduced our recent study to construct a speech interface agent which can communicate smoothly with everyday users and can be a communication partner for them. To evaluate the interaction between users and this agent model, e.g., whether a user regards this agent as a communication partner or not, we need to refer the objective indicator which reflects users' internal status accurately and reliably. We then explained the experimental setting to acquire such objective indicator based on the users' cognitive, behavioral and physiological indexes.
