Apple’s ‘Vehicle Motion Cues‘ Feature: Can Your iPhone Finally Cure Carsickness?
Table of Contents
A new iPhone feature aims to alleviate motion sickness by visually syncing screen movement with the vehicle’s motion, offering hope to passengers who struggle to read or use devices on the go.
Many find reading in a moving vehicle unfeasible. While audiobooks and music are fine, focusing on a page or screen often induces nausea. Now,Apple offers a potential solution: Vehicle Motion Cues,a feature that overlays moving dots on the screen’s edges to mirror the vehicle’s movements.
But how does it work? Understanding the root causes of motion sickness is key.
The Science of Motion Sickness
Two primary theories explain why we get sick on the move: the postural instability theory and the more widely accepted sensory conflict theory. The former suggests sickness arises from losing control of our posture – think rocky boats or roller coasters. Though, the sensory conflict theory, favored by medical research and the Centers for Disease Control (CDC), posits that motion sickness occurs when “the movement you see is different from what your inner ear senses.”
The inner ear plays a surprisingly crucial role. Beyond hearing, the vestibular system within the inner ear is essential for balance and spatial orientation. According to the Cleveland Clinic, this system relies on a fluid called endolymph; movement of this fluid, detected by hair cells, allows us to “feel” motion even with our eyes closed.
This system typically works in harmony with our vision. When we move under our own power – walking or running – both systems align. The problem arises when we aren’t controlling the movement, like in a car. Looking away from the horizon creates a disconnect: the body senses motion,but the eyes don’t register it,leading to sensory conflict and potential nausea.
The Cleveland Clinic recommends looking at distant objects or the horizon to resolve this conflict when feeling motion sick while reading. Other preventative measures include eating before travel and avoiding alcohol or smoking, both of which can exacerbate symptoms.
How Apple’s Feature Attempts to Bridge the Gap
Apple’s Vehicle Motion Cues feature, found under Accessibility > Motion in system Preferences, displays moving circles on the screen’s sides.These circles can operate continuously or activate only when the iPhone detects vehicle movement.

these circles are designed to provide a visual reference point for the vehicle’s motion.if the car accelerates, the circles move accordingly, mirroring the speed of roadside objects. Turns are similarly reflected in the circles’ movement, aiming to reduce the conflict between the eyes and inner ear.
While Apple hasn’t cited specific research inspiring the feature, a 2019 study by researchers at the University of Salzburg explored a similar approach. Their Android app utilized moving bubbles on the screen’s periphery, and participants reported reduced motion sickness, though the study was small in scale.
Currently, there’s limited research on the effectiveness of Apple’s specific implementation – it’s only been available for about a year.User reports are mixed, with some experiencing meaningful relief while others find it ineffective. Anecdotally, one user found the feature helpful while running errands. If you’re prone to carsickness while reading, toggling the feature on while in a moving vehicle could be worth a try; you might discover a newfound ability to enjoy a book on the road.
