Posture and Performance: Assessing the Influence of Body Posture and Non-Driving-Related Task Engagement on Automated Vehicle Takeover Performance
DescriptionLevel 3 Automated Driving Systems (ADS) require driver takeover upon request, necessitating readiness assessments before takeover requests. Engagement in non-driving-related tasks (NDRTs) has been shown to impair takeover performance, which may not be the case for non-urgent takeovers. This study investigates the impacts of NDRT engagement on drivers' in-vehicle posture and takeover performance during non-urgent takeovers. Forty-six participants engaged in various cognitive tasks during a simulated Level 3 driving scenario and decided when to end the NDRT. Driver posture was monitored using a pose estimation model. Overall, significant variations in posture were found to depend on NDRT, affecting both physical takeover readiness and driving performance during a takeover event. Specifically, tasks that required information organization and creation resulted in distinct hand and head positions, and increased vehicle jerk and acceleration during takeover. Findings highlight the need to design ADS interfaces that consider cognitive and physical ergonomics for improving safety.
