A Study on the Correlation between Serving Robot Form Elements and User Emotional Responses -Focusing on Design Factor Exploration Based on Emotional Evaluation-

Key Points

• The research aims to identify the relationship between the design elements of serving robots and user emotional responses.
• Conducted laddering interviews with 26 participants to derive cognitive features and emotional adjectives.
• Developed a semantic differential evaluation questionnaire with 20 bipolar adjective pairs.
• Performed SD evaluations with 62 participants to assess emotional responses.
• Conducted factor analysis to identify principal components related to robot design features.
• Identified physical properties such as 'volume' and 'stability' and emotional factors like 'friendliness' and 'convenience' as key components.
• Found a correlation between physical traits and emotional adjectives using a preference mapping approach.
• Optimal emotional responses were linked to robot silhouettes with moderate stability rather than extreme volume.
