Research on Personality Traits of In-Vehicle Intelligent Voice Assistants to Enhance Driving Experience

Despite the rapidly expanding research on in-car intelligent voice assistants, relatively little attention has been paid to the study of their personality traits and how to improve the user's emotional experience by cutting through from this perspective. In this study, first, an exploratory interview-based study is conducted to identify key traits that elicit driver emotions and five personality traits that can be used in in-car intelligent voice assistants: emotional enrichment, emotional expressiveness, persona congruence, empathic expressiveness, and user impressions. Second, an online survey-based study is conducted to investigate how the above five performance dimensions that focus on the degree of personification of intelligent assistants can be incorporated into smart car voice interaction systems in different scenarios. Finally, the ideal use cases for each personality trait are investigated, as well as how in-car intelligent voice assistants can apply the corresponding trait dimensions according to the current real-time driving situation. This study explores how the five personality trait dimensions can enhance driving users' emotional experience and emotional connection with intelligent voice assistants by adding a pleasant attitude, a sense of pleasure, and can accurately grasp users' emotional state and provide proactive services conducive to emotional appeasement and safe driving in navigation.
