Many smartphone users experience discomfort when using their devices in a moving vehicle. This problem, often known as car sickness, can arise from reading text or engaging with images while the surroundings rapidly change. Fortunately, Apple has introduced a new feature in its latest operating system aimed at alleviating this issue: Vehicle Motion Cues.
Launched with iOS 18, which rolled out in early 2024, this feature helps users manage motion sickness by displaying animated black dots on the screen while they are in a moving vehicle. These dots mimic the vehicle’s motion, providing visual cues that may help the brain reconcile the conflicting signals caused by being stationary while observing a moving environment.
Understanding the science behind car sickness is crucial. When inside a vehicle, the body remains still, but the eyes perceive motion from the passing scenery. This sensory conflict can lead to feelings of nausea, similar to seasickness or motion sickness experienced during flights. Research indicates that this phenomenon occurs because the brain struggles to process mixed signals regarding movement.
With Vehicle Motion Cues, users can either activate the feature manually or set it to automatically turn on when the device detects it is in a moving car. The feature uses the iPhone’s built-in sensors, such as accelerometers and gyroscopes, to determine when to display the moving dots. These dots appear near the edges of the screen, moving in accordance with the vehicle’s acceleration, braking, and turning, thereby reminding the brain of the body’s motion.
To enable Vehicle Motion Cues, users can follow these steps: navigate to the Settings app, select Accessibility, tap Motion, and then choose Show Vehicle Motion Cues. From there, users can opt for either Manual activation, which keeps the feature on continuously, or Automatic activation, which activates it only during car rides.
Early feedback from users on platforms like r/apple and r/iOS suggests that the feature is effective for many. One user noted, “I activated it in rough seas and while riding a bus with adventurous drivers, and it makes a huge difference for me.” Another user expressed surprise at how well it worked for them.
Despite the positive responses, experts urge caution. There is a possibility that the feature could exacerbate symptoms for some users. According to a scientist quoted in Self, “The last thing you want is to add another confusing sensory input that’s not accurate.” This means that while many may benefit, others could find the experience disorienting.
Apple emphasizes that Vehicle Motion Cues should not be used by drivers. Safety remains paramount, and users should avoid distractions while operating a vehicle.
As more users explore this new feature, it represents a significant step in addressing a common issue for smartphone users on the go. By integrating a simple yet effective tool into its iPhone ecosystem, Apple continues to enhance user experience, allowing individuals to use their devices in a more comfortable manner, even while navigating the challenges of car sickness.
