Apple's Vehicle Motion Cues Aim to Ease Travel Discomfort for Users While Reading or Using Their Phones 
Many iPhone users are discovering a little-known accessibility feature that could help reduce motion sickness while travelling in cars, trains and buses.
The feature, called Vehicle Motion Cues, displays small animated dots along the edges of the iPhone screen that move in sync with a vehicle's motion, helping the brain better process movement and reducing the sensory conflict that often causes nausea.
How the “Dancing Dots” Work
Motion sickness typically occurs when the eyes and inner ear send conflicting signals to the brain. For example, when someone looks down at a phone while travelling, their eyes perceive little movement even though the body feels acceleration, braking and turning.
Apple's Vehicle Motion Cues attempt to solve this by placing animated dots around the edges of the display. The dots subtly shift as the vehicle changes direction, accelerates or slows down, giving the eyes visual cues that match what the body is experiencing.
Researchers believe this can reduce the mismatch between visual perception and physical motion, helping many users feel more comfortable during travel.
How to Turn It On
The feature is available on supported iPhones running recent versions of iOS.
To enable it:
- Open Settings.
- Tap Accessibility.
- Select Motion.
- Tap Show Vehicle Motion Cues.
- Choose On, Automatic, or Off.
When set to Automatic, the feature activates whenever the iPhone detects that the user is travelling in a moving vehicle.
Designed With Accessibility in Mind
Apple introduced Vehicle Motion Cues as part of its broader commitment to accessibility, aiming to make devices easier and more comfortable to use for everyone.
Although primarily intended for users who experience travel-related motion sickness, the feature can benefit anyone who frequently reads, works or watches videos on their iPhone while commuting.
Expert Opinion
Health experts note that while Vehicle Motion Cues may help reduce symptoms for many people, individual experiences can vary.
Other strategies for managing motion sickness include sitting where movement is less noticeable, looking toward the horizon, ensuring good ventilation and taking regular breaks from screen use during long journeys.
For people with severe or persistent motion sickness, medical advice may still be necessary.
Technology Meets Everyday Comfort
The popularity of Vehicle Motion Cues demonstrates how smartphone technology is increasingly being used to solve practical everyday problems beyond communication and entertainment.
As more users discover the feature, Apple's innovative “dancing dots” are gaining attention as one of the most useful hidden settings available on the iPhone, particularly for commuters and frequent travellers.
