Google’s anti-nausea Motion Assist dots finally rolling out on Android

谷歌防晕动症功能“Motion Assist”圆点终于在 Android 上线

Some people are cursed with motion sickness, which can make it impossible to read or use a phone in a moving vehicle without suffering waves of nausea. There’s a surprisingly simple trick that can make smartphones usable in such situations. Apple deployed it on the iPhone a couple of years ago, and now Google’s own version is finally coming (slowly) to Android.

有些人深受晕动症（晕车）之苦，这使得他们在移动的车辆中阅读或使用手机时，往往会感到阵阵恶心。其实，有一个出奇简单的技巧可以让智能手机在这种情况下正常使用。苹果公司几年前已经在 iPhone 上推出了该功能，现在谷歌的版本也终于（缓慢地）来到了 Android 平台。

Motion sickness is caused by a disagreement between what your inner ear senses and what your eyes see. If you’re looking at a book or a screen while in a car, the sensory mismatch can lead to a pretty unpleasant time. As part of iOS 18 in 2024, Apple released a feature called Motion Cues that places a network of moving dots on the screen to alleviate motion sickness, and it seems to work surprisingly well. Google’s version is similar, but it’s called Motion Assist.

晕动症是由内耳感知与眼睛所见之间的不一致引起的。如果你在车里盯着书本或屏幕看，这种感官上的错位会导致非常不适的体验。作为 2024 年 iOS 18 的一部分，苹果发布了一项名为“车辆运动提示”（Motion Cues）的功能，通过在屏幕上显示一组移动的圆点来缓解晕动症，而且效果出奇地好。谷歌的版本与之类似，但被称为“Motion Assist”。

Google began testing Motion Assist back in 2024, but it never expanded beyond an internal test until now. Android Authority reports Motion Assist is appearing on Pixel phones running Android 17, but there’s no app or update you can install to get the feature—it’s being delivered by Play Services as part of a staged rollout.

谷歌早在 2024 年就开始测试 Motion Assist，但直到现在它才走出内部测试阶段。据 Android Authority 报道，运行 Android 17 的 Pixel 手机已经开始出现该功能，但用户无法通过安装应用程序或更新来获取它——它是通过 Google Play 服务以分阶段推送的形式提供的。

When activated, Motion Assist adds small dots around the edges of your phone screen over top of the content. It plugs into your phone’s accelerometer and gyroscope, allowing the dots to move in concert with the motion of the vehicle; they travel down the screen while the vehicle is moving forward, to the left when turning right, and so on. They basically mimic the way objects in the real world would move through your vision if you weren’t glued to the screen.

激活后，Motion Assist 会在手机屏幕边缘覆盖一层小圆点。它会调用手机的加速度计和陀螺仪，使这些圆点能够随着车辆的运动而同步移动；当车辆向前行驶时，圆点会向下移动；当车辆向右转弯时，圆点会向左移动，以此类推。它们基本上模拟了如果你没有盯着屏幕看时，现实世界中的物体在你视野中移动的方式。

People who have used Apple’s anti-nausea dots have reported that the feature works wonders in reducing motion sickness. So there’s every reason to expect Google’s version will be similarly effective. Motion Assist can be activated manually as needed from the menu or using a quick settings tile. You can also let your phone turn it on automatically when it detects you’re in a moving vehicle.

使用过苹果防晕动圆点的用户反馈称，该功能在减轻晕动症方面效果显著。因此，我们完全有理由期待谷歌的版本也能达到同样的效果。Motion Assist 可以根据需要通过菜单或快速设置磁贴手动激活。你也可以设置让手机在检测到你处于移动车辆中时自动开启该功能。

Google’s version of this feature also includes a few customization options, letting you change the shape, size, color, and opacity of the anti-nausea dots. If Motion Assist is available on your phone, you’ll find it in the Google services settings, usually nested one level below the main settings: Settings > Your profile > All services. Motion Assist will be under the Personal & Device section near the bottom.

谷歌版本的该功能还包含了一些自定义选项，允许你更改防晕动圆点的形状、大小、颜色和透明度。如果你的手机支持 Motion Assist，你可以在谷歌服务设置中找到它，通常位于主设置下一级：设置 > 个人资料 > 所有服务。Motion Assist 将位于底部的“个人与设备”部分下。

So far, Motion Assist has only appeared on Pixel phones running Android 17. The feature was obviously tested on earlier versions of Android, but it’s unclear if the final version will be exclusive to either Google’s phones or the latest version of Android. We’ve reached out to Google for clarification on this point.

到目前为止，Motion Assist 仅出现在运行 Android 17 的 Pixel 手机上。显然，该功能曾在更早版本的 Android 上进行过测试，但目前尚不清楚最终版本是否会仅限于谷歌手机或最新版本的 Android 系统。我们已联系谷歌以寻求对此点的澄清。
