Gesture design attribute and level value of social robot: A user experience based study

This study was to verify the attributes of the social robot's gesture design factors that has a significant difference in the user experience and to establish the level values of the attributes. To do so, the attributes and the level value standards for the gesture interface's key design factors have been organized and a user experience survey was conducted through researches on the existing literature and case studies. For the emotional gesture attributes, the level values were categorized as 'pleasure at low arousal', 'pleasure at high arousal', 'displeasure at low arousal', and 'displeasure at high arousal'. Among the communicative expression gesture attributes, the level values were categorized as ‘idling, conversation induction and concentration, and empathy’. Lastly, the derived attributes and the level values for the ‘emotional gesture’ and ‘communicative gesture’ have been integrated with the ones for the ‘functional/semantic gesture' derived on the previous studies; they have been presented as the robot's gesture interface design factors available in the aspect of the user experience.
