ABSTRACT ABSTRACT This paper proposes a model,of approach,behavior with which a robot can initiate conversation with people who,are walking. We developed,the model by learning,from the failures in a simplistic approach,behavior ,used in a ,real shopping ,mall. Sometimes people were unaware of the robot’s presence, even when it spoke tothem. Sometimes, people were not sure whether the robot was really trying to start a conversation, and they did not start talking with it even ,though ,they displayed interest. To prevent ,such failures, our model includes the following functions: predicting the walking behavior of people, choosing a target person, planning its approaching path, and nonverbally indicating its intention to initiate ,a conversation. ,The approach ,model ,was implemented,and ,used in a ,real shopping ,mall. The field trial demonstrated,that our model ,significantly improves ,the robot’s performance,in initiating conversations.

    ABSTRACT: Walking side by side is a common situation when we go from one place to another with another person while talking. Our previous study reported a basic mechanism for side-by-side walking, but in the previous model it was crucial that each agent knew where he or she was going, i.e. the route to the destination. However, we have recognized the need to model the situation where one of the agents does not know the destination. The extended model presented in this work has two states: leader-follower state and collaborative state. Depending on whether the follower agent has obtained a reliable estimate of the route to follow, the walking agents transition between the two states. The model is calibrated with trajectories acquired from pairs of people walking side by side, and then it is tested in a human-robot interaction scenario. The results demonstrate that the new extended model achieves better side-by-side performance than a standard method without knowledge of the subgoal.

    ABSTRACT: Introduction of user models (e.g. models of a user's belief, skill and familiarity to the system) is believed to increase flexibility of response of a dialogue system. Conventionally, the internal state is estimated based on linguistic information of the previous utterance, but this approach cannot applied to the user who did not make an input utterance in the first place. Thus, we are developing a method to estimate an internal state of a spoken dialogue system's user before his/her input utterance. In a previous report, we used three acoustic features and a visual feature based on manual labels. In this paper, we introduced new features for the estimation: length of filled pause and face orientation angles. Then, we examined effectiveness of the proposed features by experiments. As a result, we obtained a three-class discrimination accuracy of 85.6% in an open test, which was 1.5 point higher than the result obtained using the previous feature set.

    ABSTRACT: To enable natural and productive situated human-robot interaction, a robot must both understand and control proxemics, the social use of space, in order to employ communication mechanisms analogous to those used by humans: social speech and gesture production and recognition. My research focuses on answering these questions: How do social (auditory and visual) and environmental (noisy and occluding) stimuli influence spatially situated communication between humans and robots, and how should a robot dynamically adjust its communication mechanisms to maximize human perceptions of its social signals in the presence of extrinsic and intrinsic sensory interference?
