Reusable semantic differential scales for measuring social response to robots

Abstract

This paper presents eight novel reusable semantic differential scales measuring a variety of concepts relevant to the field of social HRI: Understandability, Persuasiveness, Naturalness, Appropriateness, Welcome, Appeal, Unobtrusiveness and Ease. These scales were successfully used in two HRI experiments, and were found to have acceptable (> 0.7) or higher levels of internal reliability. These scales are reusable and were designed to simplify comparison between HRI studies, especially in the area of social robotics, where measuring the quality of interaction and social response to robots is of paramount importance.
