Peripheral Vibrotactile Cues Enhance Situation Awareness but Do Not Alleviate Motion Sickness in Autonomous Vehicles
Providing passengers with peripheral vibrotactile information about upcoming vehicle maneuvers can improve their awareness of the driving situation but does not inherently reduce motion sickness.
International Journal of Automotive and Mechanical Engineering · 2020
Key Findings
- 01The vibrotactile display significantly increased passengers' situation awareness.
- 02The vibrotactile display did not significantly reduce motion sickness symptoms.
Application
Design takeaway
Designers should not assume that increased situational awareness through haptic feedback will automatically reduce motion sickness; a multi-faceted approach is likely needed.
How to apply
When designing haptic feedback systems for autonomous vehicles, consider incorporating information directly related to motion prediction and vehicle dynamics, and explore complementary solutions for motion sickness.
Project actions
- 01When designing for comfort in automated vehicles, think about more than just information delivery; consider the passenger's physical well-being.
- 02If you are investigating motion sickness, ensure your design addresses the physiological aspects, not just cognitive awareness.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Utilized a real-world driving environment for greater ecological validity.
- +Employed a 'Wizard of Oz' method for robust simulation control.
Limitations
The specific nature of the vibrotactile cues was not detailed, making it hard to replicate or adapt without further information. The study did not explore individual differences in susceptibility to motion sickness.
Reliability & validity
The use of objective and subjective measures for both situation awareness and motion sickness enhances the study's validity. The sample size of 20 participants may limit generalizability, impacting reliability across broader populations.
Think critically
If increased situation awareness did not reduce motion sickness, what other factors might be more influential in mitigating this issue for passengers in automated vehicles?
Design Principles
"Sensory feedback for motion sickness mitigation in automated vehicles requires a holistic design that addresses both cognitive awareness and physiological responses."
As vehicles become more automated, understanding how to maintain passenger comfort and engagement is crucial. This research highlights a gap in current haptic feedback strategies, suggesting that while awareness can be boosted, the complex physiological response of motion sickness requires a more nuanced approach.
What This Means for Your Design
Giving car passengers little buzzes to tell them what the car is going to do makes them more aware, but it doesn't stop them from feeling sick.
How to use in your project
- 1.Use this study to justify the need for a multi-modal approach in your design for passenger comfort in automated vehicles.
- 2.Reference this study when discussing the limitations of purely informational feedback systems for mitigating motion sickness.

Paragraph starter
Research by Yusof et al. (2020) demonstrated that while peripheral vibrotactile cues can enhance situation awareness in automated vehicles, they did not significantly reduce motion sickness. This suggests that a comprehensive design approach is necessary, addressing both informational needs and physiological responses to ensure passenger comfort and well-being in future mobility solutions.
