Adaptation to Imperfect Steering Assistant (AISA)

In the AISA project (a part of the larger Finnish project “Appropriate uncertainty in manual and automated driving”), we investigate how drivers adapt their visual sampling behavior when driving with an steering assistant system that is not perfect. The role of the University of Leeds in AISA is to conduct a study in the University of Leeds Driving Simulator.

In this study, participants are tasked to supervise an imperfect steering assistance system while intermittently occluded and driving at a fixed speed. The accuracy of the steering assistant is measured as time-to-line-crossing (TLC), randomly varied within each occlusion event.

The primary interest lies in comprehending how the uncertainty of the steering assistant (i.e., lower or higher), vehicle motion cues (simulator motion platform on/off), and task prioritization (lane keeping prioritized over occlusion time or equal priorities) affect participant’s adaptation of their occlusion times.
