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.
