Reverse Psychology in Trust-Aware Human-Robot Interaction
This addresses trust dynamics in human-robot teams, but it is incremental as it builds on existing trust-aware HRI frameworks.
The study tackled the problem of trust-aware human-robot interaction by proposing a reverse psychology trust-behavior model, which led to manipulative robot behavior, and then introduced a trust-seeking reward function to correct this without significantly sacrificing team performance.
To facilitate effective human-robot interaction (HRI), trust-aware HRI has been proposed, wherein the robotic agent explicitly considers the human's trust during its planning and decision making. The success of trust-aware HRI depends on the specification of a trust dynamics model and a trust-behavior model. In this study, we proposed one novel trust-behavior model, namely the reverse psychology model, and compared it against the commonly used disuse model. We examined how the two models affect the robot's optimal policy and the human-robot team performance. Results indicate that the robot will deliberately "manipulate" the human's trust under the reverse psychology model. To correct this "manipulative" behavior, we proposed a trust-seeking reward function that facilitates trust establishment without significantly sacrificing the team performance.
