Abstract
Qualitative expressions using an Antenna Hair-type Object for Generating Empathy (AHOGE) are proposed for information presentation system, where the expressed motions by the AHOGE change according to the qualitative evaluation by the information presentation system. To estimate effects of the proposed expression by the AHOGE on human, two types of questionary investigations are performed in the three prepared scenarios, where impression and memory are evaluated in a human-robot interaction situation. It is confirmed that the proposed expressions work effectively to human memory by impressing qualitative information.
