Wang, J. Martens, M.H. Verwey, W.B. Publication year 2019 Abstract Studies show that drivers’ intention to use automated vehicles is strongly modulated by trust. It follows that their benefits are unlikely to be achieved if users do not trust them. To date, most studies of trust in automated vehicles have relied on self-reports. However, questionnaires cannot capture real-time changes in drivers’ trust, and are hard to use in applied settings. In previous work, we found evidence that gaze behaviour could provide an effective measure of trust. In this study we tested whether combining gaze behaviour with Electrodermal Activity could provide a stronger metric. The results indicated a strong relationship between self-reported trust, monitoring behaviour and Electrodermal Activity: The higher participants’ self-reported trust, the less they monitored the road, the more attention they paid to a non-driving related secondary task, and the lower their Electrodermal Activity. We also found evidence that combined measures of gaze behaviour and Electrodermal Activity predict self-reported trust better than either of these measures on its own. These findings suggest that such combined measures have the potential to provide a reliable and objective real-time indicator of driver trust. © 2019 Elsevier Ltd Subject Electrodermal ActivityEye movement behaviourSecondary taskTrust calibrationTrust in automationAutomationEye movementsSurveysVehiclesAutomated drivingAutomated vehiclesEffective measuresElectrodermal activityMovement behaviourObjective measureReal-time changesSecondary tasksElectrodes To reference this document use: http://resolver.tudelft.nl/uuid:de55233f-cc6a-4d6a-8894-4667d0cdd1f0 DOI https://doi.org/10.1016/j.trf.2019.05.021 TNO identifier 867840 ISSN 1369-8478 Source Transportation Research Part F: Traffic Psychology and Behaviour, 64, 401-412 Document type article Files To receive the publication files, please send an e-mail request to TNO Library.
