Anticipatory Vibrotactile Cues Show No Significant Effect on Motion Sickness Mitigation

Anticipatory vibrotactile cues, even when timed precisely, did not significantly reduce motion sickness in participants exposed to predictable linear motion.

Experimental Brain Research · 2023

Key Findings

01Anticipatory vibrotactile cues did not significantly mitigate motion sickness under the tested conditions.
02The timing of the vibrotactile cue (0.33s, 1s, or 3s prior to motion) did not affect its ability to reduce motion sickness.
03Participants reported that the cues were helpful, despite the lack of statistically significant sickness reduction.

Application

Design takeaway

How to apply

When designing interfaces for autonomous vehicles or other motion-sensitive environments, consider incorporating a multi-modal approach to passenger comfort, rather than relying on a single sensory cue. Test feedback systems under a wide range of motion conditions.

Project actions

01When testing sensory feedback, ensure your motion stimuli are varied and representative of real-world scenarios.
02Consider both objective measures (like sickness scores) and subjective feedback (user perception) in your analysis.

Method & Evidence

AimTo determine if anticipatory vibrotactile cues can mitigate motion sickness and if the timing of these cues influences their effectiveness.

MethodExperimental study

ProcedureParticipants were exposed to four sessions on a linear sled with unpredictable motion onset. In three sessions, a vibrotactile cue was presented 0.33, 1, or 3 seconds before forward motion. A control session with no cue was also conducted. Motion sickness was quantified using multiple sickness scores.

ContextAutonomous vehicle passenger experience, motion-based simulation.

Variables

IVPresence and timing of anticipatory vibrotactile cues.

DVMotion sickness scores.

CVLinear sled motion onset, type of motion (forward), participant exposure to different cue timings.

Strengths & Limitations

Strengths

+Uses a novel pre-registered measure for quantifying motion sickness.
+Investigates the influence of cue timing, adding nuance to the research.

Limitations

The study's findings might not apply to situations with more complex or unpredictable movements, such as those found in actual driving or turbulent environments.

Reliability & validity

The study's validity might be limited by the artificiality of the linear sled environment. Reliability would depend on consistent application of motion and cue delivery.

Think critically

Given that participants found the cues helpful but they didn't reduce sickness, what does this imply about the psychological versus physiological components of motion sickness mitigation?

Design Principles

"The efficacy of sensory cues for mitigating motion sickness is dependent on the predictability and variability of the motion itself."

This research is crucial for designers of autonomous vehicle interiors and other motion-based experiences. While vibrotactile feedback is a promising modality for conveying information without disrupting other tasks, its effectiveness in mitigating motion sickness requires further investigation, particularly under varied motion conditions.

What This Means for Your Design

Vibrations meant to warn you about movement in a car didn't actually make people feel less sick, even though people said they liked getting the warning.

Paragraph starter

Research by Reuten et al. (2023) investigated the effectiveness of anticipatory vibrotactile cues in mitigating motion sickness. Their findings indicated that, under conditions of predictable linear motion, these cues did not significantly reduce sickness, despite participants reporting them as helpful. This suggests that the context of motion variability is critical when designing sensory feedback for passenger comfort.
