Interpersonal motions for mobile eye robot and its mentality expression

Interpersonal motions and their expression are proposed for a mobile eye robot. An interpersonal motion that consists of an interpersonal distance, a motion speed, and a motion trajectory is determined according to verbal information received from human in an interactive situation using a proposed fuzzy inference based on a mental distance type pleasure-arousal space. Interactive experiments with two scenarios are performed in an information recommendation situation with the mascot robot system. Subjective estimations using psychological scale are conducted for 11 subjects. Since the results of the subjective estimation show 3.08 and 2.62 (out of 6), the validity of the interpersonal motions expression is confirmed. The system provides user-friendly and casual information recommendation, which is essential for wide spread family use.
