Transparent Conversational Agents: The Impact of Capability Communication on User Behavior and Mental Model Alignment
Year: 2025
Type: conference-paper
Abstract: When a user interacts with a conversational agent for the first time, they may not be aware of the agent’s capabilities, leading to suboptimal use or interaction breakdowns. To avoid a mismatch with the actual capabilities, the agent’s capabilities have to be made transparent to the user. To investigate whether communication of an agent’s capabilities during interactions enhances transparency and improves the user’s mental model, we conducted a user study with 56 participants. Each participant had three speech-based interactions with an agent that communicated its capabilities or an agent that did not. Our results suggest that the communication led to a change in user behavior with significantly longer utterances. However, the users’ mental models of the agent’s capabilities were not significantly different between the conditions. Participants were able to significantly improve their knowledge of the agent’s capabilities by aligning their mental model over time in both conditions.
