Monitoring Trust Levels in Human-Machine Engagements in Real-Time
In a groundbreaking development, a new trust sensor model has been designed to determine real-time human trust levels in human-machine interactions. Known as the empirical trust sensor model, this innovative system uses psychophysiological measurements to gauge trust levels during human-machine interactions.
The model relies on three core psychophysiological inputs: skin conductance responses (SCR), heart rate (HR), and eye movement data. These signals provide objective indicators of physiological arousal and stress, which correlate with trust or distrust states during interaction.
During trust assessment tasks, participants wear biometric sensors, such as those on the wrist, to record skin conductance. This measurement reflects sympathetic nervous system activity and thus stress or arousal levels when evaluating a machine or agent. The model also integrates additional physiological data, including heart rate and gaze tracking, to build a comprehensive representation of the participant’s cognitive and affective state as they engage with the system.
By combining these biosignals with behavioral data, machine learning models can predict trust levels dynamically and continuously. Self-supervised learning techniques applied on these multimodal physiological datasets improve the model’s generalizability and robustness across different contexts.
While the exact mean accuracy of the specific empirical trust sensor model is not stated in the excerpts, comparable trust prediction systems using similar physiological measures and machine learning approaches have achieved promising results, often reporting accuracy levels around or above 80% in distinguishing trust states in experimental settings.
The empirical trust sensor model represents a significant step forward in the development of human-machine interfaces, as it offers a means to understand and respond to human trust levels in real-time. Future work will consider the effect of human demographics on feature selection and modeling, aiming to further refine the model's accuracy and applicability.

The empirical trust sensor model, using psychophysiological measurements like skin conductance, heart rate, and eye movement data, is designed to assess mental health and wellness during human-machine interactions, particularly trust or distrust states. This comprehensive representation of the participant's cognitive and affective state during engagement with the system could potentially lead to improved therapies and treatments for mental health issues.
By predicting trust levels dynamically and continuously, self-supervised learning techniques applied on these multimodal physiological datasets in the field of health-and-wellness can help improve the generalizability and robustness of trust prediction systems across different contexts.
