Abstract
We aim at a robot to manipulate human's mental state. Manipulating human's mental state, a robot is expected to relieve human's anxiety or decrease human's unpleasant feelings. It is known that human's facial expression is one of the signal caused by a change of mental state. As a means to manipulate human's mental state, we have been proposed an action selection method of predicting human's facial expression. A robot is expected to selects an action based on prediction of human's facial expression to elicit arbitrary human's expression. Using the method, we performed an experiment of arbitrary human's facial expression elicitation with Mof-mof robot. Mof-mof robot selected some actions to elicit happy, surprised, angry and surprised facial expression from examinees. In some cases, several types of a target facial expression seems to be elicited by robot's action.
