The Role of Personality in AI Chatbots

As conversational AI gains traction in industrial settings, the role of chatbot personality in shaping user experience becomes increasingly relevant. This study explores how chatbot personalities can enhance user experience within test and verification systems within industrial environments. Three distinct personas, The Expert, The Friendly, and The Machine were designed based on defined personality dimensions for conversational agents, informed by previous research. Expert interviews guided the development of realistic test scenarios, followed by user testing and semi-structured interviews. Collected data was analyzed using thematic analysis. This study contributes new knowledge on UX/UI principles for AI-powered chatbots, examining how personality affects user experience and trust. Findings suggest that aligning chatbot personality with user context and expectations is key to fostering trust and improving the overall usability of industrial AI systems.
