Trust in automation: An on-road study of trust in advanced driver assistance systems

A
ppropriate user trust is critical in ensuring the acceptance and safe use of Advanced Driver Assistance Systems
(ADAS). Despite the prevalence of ADAS on-road today, there is a limited understanding of how trust is affected
by a user’s first contact with the system on-road. Ten participants without prior experience were introduced to a level
2 system and completed an on-road test drive session. Utilizing a mixed-methods approach including the Trust in
Automation (TiA) questionnaire, verbal trust scores and Facial Emotion Recognition (FER), trust in the system was
measured at key milestones. TiA scores increased in a majority of participants, and a significant shift in the factor
Reliability/Competence (p=0.02) was observed post-drive. According to FER scores, participants with a gain in
TiA post-drive and those with a loss in TiA post-drive, more frequently displayed the emotions happy and angry,
respectively. Results indicate that trust increases after a user’s first experience with ADAS and further that FER may
be predictive of user trust in automation.
