"What does your Agent look like?": A Drawing Study to Understand Users' Perceived Persona of Conversational Agent

Conversational agents (CAs) become more popular and useful at home. Creating the persona is an important part of designing the conversational user interface (CUI). Since the CUI is a voice-mediated interface, users naturally form an image of the CA's persona through the voice. Because that image affects users' interaction with CAs while using a CUI, we tried to understand users' perception via drawing method. We asked 31 users to draw an image of the CA that communicates with the user. Through a qualitative analysis of the collected drawings and interviews, we could see the various types of CA personas perceived by users and found design factors that influenced users' perception. Our findings help us understand persona perception, and that will provide designers with design implications for creating an appropriate persona.
