Summary

This study investigates auditory interventions delivered via in-car voice assistants to counteract passive driver fatigue, a state of cognitive underload caused by prolonged, monotonous driving. While secondary tasks can stimulate drivers, poorly designed interventions may compromise safety by causing distraction. The research aims to identify strategies that boost driver arousal without significantly deteriorating driving performance, specifically comparing music and interactive story games across varying levels of driver participation. The researchers conducted a within-subject study with 21 participants using a driving simulator featuring a monotonous highway environment. Participants engaged in two activity types—Music and Interactive Story Games—under three participation modes: Passive listening, Vocal interaction (singing or verbal choices), and Physical interaction (rhythmic steering taps or head nods). Physiological arousal was measured using electroencephalography (EEG) and electrodermal activity (EDA). Driving performance was assessed through steering wheel reversal rate (SRR) and driving performance metrics (DPM), which tracked lane deviations, speeding, following distance violations, and averted visual attention. Results indicated that music significantly increased arousal compared to interactive stories, as measured by both EEG and EDA, while imposing a smaller adverse effect on driving performance. Interactive stories, while effective at raising arousal, resulted in higher rates of driving errors and cognitive load. Regarding participation levels, vocal participation yielded the most favorable balance between arousal enhancement and driving safety. Physical participation produced the highest arousal levels but also the worst driving performance, whereas passive listening resulted in the lowest arousal and best performance. Statistical analysis confirmed significant main effects for both activity type and participation level on arousal and performance metrics, with no significant influence from demographic variables. The findings suggest that in-car voice assistants can effectively mitigate passive fatigue by recommending music over complex interactive stories, particularly when encouraging vocal participation. This approach maintains driver alertness with minimal distraction, offering a viable strategy for both manual and semi-automated driving contexts where driver readiness for takeover is critical. The study highlights the potential for adaptive systems that tailor auditory interventions to optimize the arousal-to-distraction ratio, thereby enhancing road safety. Future work is recommended to refine these interventions and explore real-world applications, potentially leveraging large language models to create more immersive and context-aware auditory experiences.
