苹果iPhone内置一项鲜为人知的功能"Vehicle Motion Cues"，旨在帮助用户缓解晕车不适[1]。该功能通过在屏幕边缘显示与车辆运动同步的动画点，利用手机加速度计检测运动，为用户提供空间运动感知反馈[1]。用户可在"iPhone Settings > Accessibility > Motion > Vehicle Motion Cues"路径下启用此功能，并自定义点的大小和颜色[1]。
这一功能已获得多名用户的正面评价[1]。研究表明，"视觉反馈能够非常有帮助"[1]。一些使用者称该功能"改变了游戏规则"，还有人表示"这些点真的有效"[1]。不过，也有使用者反映效果不明显[1]。此外，该功能的潜在弊端是可能鼓励用户增加屏幕使用时间[1]。
目前，第三方Android应用已开始复制这一设置，传言谷歌Pixel手机即将推出类似功能[1]。
Apple has integrated a lesser-known accessibility feature into iPhone settings that aims to alleviate motion sickness symptoms. Called "Vehicle Motion Cues," the setting displays animated dots synchronized with vehicle movement around the screen's edges, helping users maintain spatial awareness during travel.[1] The feature works by detecting motion through the iPhone's accelerometer and providing visual feedback based on established medical principles for managing motion-related discomfort.[1]
To enable the feature, users can navigate to Settings > Accessibility > Motion > Vehicle Motion Cues on their devices.[1] The dots can be customized in both size and color to suit individual preferences.[1] User experiences with the feature vary considerably: some report significant relief, with one user stating "It's been a game changer,"[1] while others describe the dots as highly effective.[1] However, not all users find the feature beneficial.[1] A medical researcher noted that "There is some research that has looked into visual feedback and found it can be very helpful."[1]
A notable drawback of relying on the feature is that it encourages extended screen time during travel.[1] Beyond Apple's ecosystem, the concept has attracted attention from other manufacturers; Android developers have created similar applications, and reports suggest that Google's Pixel phones may introduce comparable functionality in the future.[1]
