Transitions of User Internal States by Transition of Agent States

We propose a model for designing embodied virtual agents for use in online retailing. Such agents are necessary for transiting user internal states to manipulate the decision-making process. To satisfy this demand, the agents need to build a trustworthy relationship with users through interactions. In our model, user internal state transitions are derived from agent state transitions. The trustworthiness of agents changes according to agent states and is difficult to operate directly. We define two factors of trustworthiness, emotion and intelligence, and propose a way to transit these two factors of the agents to improve their trustworthiness.
