Robot confidence and trust alignment

Trust in automation plays a crucial role in human-robot interaction and usually varies during interactions. In scenarios of shared control, the ideal pattern is for the user's real-time trust in the robot to align with robot performance. This should lead to an increased overall efficiency of the system by limiting under-trust and over-trust. However, users sometimes display incorrect trust and the ability to detect and alter user trust is important. This paper describes measures for real-time trust alignment.
