This paper proposes a multimodal interactive approach to improving recognition performance of objects a person indicates to a robot. We considered two phenomena in human-human and human-robot interaction to design the approach: alignment and alignment inhibition. Alignment is a phenomenon that people tend to use the same words or gestures as their interlocutor uses; alignment inhibition is an opposite phenomenon, which people tend to decrease the amount of information in their words and gestures when their interlocutor uses excess information. Based on the phenomena, we designed robotic behavior policies that a robot should use enough information without being excessive to identify objects so that people would use similar information with the robot to refer to those objects, which would contribute to improve recognition performance. To verify our design, we developed a robotic system to recognize the objects to which people referred and conducted an experiment in which we manipulated the redundancy of information used in the confirmation behavior. The results showed that proposed approach improved recognition performance of objects to which referred by people.

The recognition of indicated objects by interacting people is an essential function for robots that act in daily environments. However, due to ambiguous references by them, accurate recognition of indicated objects have difficulties for the robots. For example, people sometimes use the words which did not contain in the robots' databases, or they did not use enough words to identify the object. Therefore, to improve recognition accuracy, we must decrease such ambiguity of indicating behaviors of people. For this purpose, we experimentally compared two kinds of interaction strategies to decrease the ambiguity: explicitly providing requests to people about how to refer to objects, or implicitly aligning with people's indicating behaviors. The experimental results showed that participants evaluated the implicit strategy to be more natural than the explicit strategy, and the recognition performances of the two strategies were not significantly different.
