Summary
This study investigates how the location of in-vehicle displays affects motion sickness in passengers, specifically isolating the impact of head motion from sensory conflict. As smart cockpits encourage passengers to engage in non-driving related tasks (NDRTs) like entertainment or work, prolonged screen viewing can induce motion sickness due to sensory mismatch and altered head posture. While previous research established that display location influences sickness, it failed to distinguish between the effects of visual sensory conflict and the mechanical influence of head orientation on vestibular stimulation. This paper aims to evaluate motion sickness induction across four common display locations and differentiate the role of head motion. The researchers employed a simulation-based approach combining empirical data with theoretical models. First, they measured the head poses of seven participants (aged 26–31) when viewing displays at four specific locations in a stationary vehicle: a headrest screen, a lower backrest screen, an armrest screen, and a roof-mounted screen. Head rotation angles were recorded using an IMU attached to a helmet. Second, they collected a real-world vehicle dynamic profile during a 75-minute, 31.2-kilometer drive in Guangzhou, China, capturing longitudinal, lateral, and vertical accelerations. These vehicle dynamics were then translated into head motion using a motion transfer function. Finally, a 6-degree-of-freedom (DoF) subjective vertical conflict (SVC) model was used to calculate the Motion Sickness Index (MSI) for each display location, simulating the vestibular response to the combined vehicle and head motion. The results indicated significant individual variability in head positioning, even when participants viewed the same display location. Statistical analysis using a Friedman test revealed a significant difference in the final MSI among the four display positions ($p = .03$). Post-hoc pairwise comparisons showed a marginally significant difference between the armrest display and the roof display ($p = .08$), with the roof display resulting in a higher MSI. The armrest display yielded the lowest simulated motion sickness index. The vehicle dynamics data confirmed that the drive included acceleration frequencies known to induce motion sickness, particularly in the 0.2 Hz lateral range and 0.8–8 Hz vertical range. The findings suggest that display location significantly influences motion sickness through its effect on head motion, independent of visual sensory conflict. The lower MSI associated with the armrest display contrasts with previous findings that higher displays (like head-up displays) reduce sickness by improving road visibility, highlighting a conflict between optimizing for vestibular head motion versus visual motion cues. The study validates the feasibility of using the 6-DoF SVC model and motion transfer functions to predict motion sickness based on head posture. These insights inform the ergonomic design of smart cockpits, suggesting that lower display placements may mitigate vestibular-related motion sickness, though further on-road experiments are needed to quantify the combined effects of visual and vestibular factors.
Key finding
Simulated motion sickness levels varied significantly by display location, with the armrest display resulting in the lowest motion sickness index and the roof display showing marginally higher levels than the armrest.
