How to Activate Your iPhone’s Motion Sickness Prevention Tool

These subtle indicators might help you avoid nausea during your next car journey.

Using your phone in a moving vehicle often triggers motion sickness. Despite the discomfort, many passengers still attempt to scroll through their devices while traveling. Apple’s iOS 18 introduces a solution to reduce this sensory conflict: Vehicle Motion Cues. Here’s how to enable it.

What is Motion Sickness

Motion sickness arises when your body receives conflicting signals—your eyes perceive a stationary screen, while your inner ear senses the vehicle’s motion. This mismatch can lead to symptoms like nausea, dizziness, and headaches.

How Vehicle Motion Cues Work

Integrated into iOS 18, Vehicle Motion Cues display dynamic dots along the edges of your screen. These animations mirror the vehicle’s movement, providing visual cues to align your sensory input. Notably, these dots don’t appear in screenshots or screen recordings, ensuring seamless use.

Step-by-Step Activation Guide

1. Open Settings: Launch the Settings app on your iPhone.

2. Accessibility Menu: Tap “Accessibility” in the settings list.

3. Motion Settings: Under the “Vision” section, select “Motion.”

4. Enable Feature: Choose “Vehicle Motion Cues” from the menu.

5. Adjust Preferences: Toggle between “On” (permanent activation) or “Automatic” (activates only when motion is detected).

By activating this tool, your iPhone adapts to reduce sensory dissonance, making travel more comfortable. Whether you enable it manually or rely on automatic detection, these cues offer a practical way to stay symptom-free on the go.
