Apple has introduced Vehicle Motion Cues, a feature designed to help reduce motion sickness for passengers in moving vehicles such as cars and buses. The technology operates by displaying small animated dots on the iPhone screen that synchronize with the vehicle's motion. This visual input aims to align visual perception with inner ear signals, addressing a common theory that motion sickness is triggered by a poor perception of movement. Primarily intended for forward-facing passengers, the Vehicle Motion Cues feature can be added to a device's Control Center for quick access. Initial user feedback indicates that while some users may experience relief, effectiveness can vary, and a period of adjustment might be required.
