The robot ‘Lometh’is an information-presenting robot that naturally interacts with people in a supermarket environment. In recent years,considerable effort has been devoted to the implementation of robotic interfaces to identify effective behaviors of communication robots focusing only on the social and physical factors of the addresserand the hearer. As attention focus and attention target shifting of peoplediffers based on the human visual focus and the spatiality, this study considered four interactive regions, considering the visual focus of attention as well as the interpersonal space between robot and human. The collected primary data revealed that 56% attention shifts occurred in nearperipheral field of view regions and 44% attention shifts in farperipheral field of view regions. Using correspondence analysis,we identified that the bodily behaviors of the robot showed the highest success ratein the left nearperipheral field of view region. The verbal behaviors of the robot captured human attention best in the right nearperipheral field of view region. In this experiment of finding asocially acceptable way to accomplish the attention attractinggoals of a communication robot, we observed that the robots’ affective behaviors were successful in shifting human attention towards itselfin both left and right far-peripheral field of viewregions, so we concludedthat for farfield of view regions, designing similar interaction interventions can be expected to besuccessful.
