Speaking of Trust -- Speech as a Measure of Trust
This addresses the challenge of subjective or non-real-time trust measures for users in human-robot interaction, but it appears incremental as it builds on existing ideas of using behavioral cues.
The paper tackles the problem of measuring trust in human-robot interaction by proposing speech cues as an objective, real-time measure, which could enable robots to calibrate appropriately, though it also raises ethical concerns.
Since trust measures in human-robot interaction are often subjective or not possible to implement real-time, we propose to use speech cues (on what, when and how the user talks) as an objective real-time measure of trust. This could be implemented in the robot to calibrate towards appropriate trust. However, we would like to open the discussion on how to deal with the ethical implications surrounding this trust measure.
