• Abstract:
  This study aimed to assess the potential of driver distraction, task performance, orientation of ; attention, and perceived workload in a multitasking situation involving interaction with touchscreen ; interface, compared to physical interface. Authors conducted a real-driving experiment focusing on ; qualities of synthetic feedback produced from the interfaces mounted on the center console, when a ; driver engages in an input task with the interfaces while maintaining visual attention and awareness on ; the road and the roadside. Participants drove a vehicle along a straight double-lane route prescribed on ; the closed-course track in Texas A&M University–Riverside Campus. The results revealed that the ; lack of both auditory and vibro-tactile feedback in touchscreen interaction led to significant ; degradation in input task performance, compared to a natural haptic feedback from the physical ; interface. The insufficiency also significantly deteriorated drivers’ ability in detecting and promptly ; responding to objects designed to suddenly appear on the roadside, as opposed to the physical interface ; or touchscreen interface with synthetic feedback. Perceived workload appeared to be not significantly ; affected by the difference in the interface characteristics. The findings emphasized the impact of ; synthetic feedback on multitasking performance as previous studies did, and highlighted its potential ; on regulating visual attention resource on which awareness is based. Designers of user interface or ; policy makers concerning with driving safety will benefit from the findings.
