Meta智能眼镜新增驾驶模式：自动关闭显示屏，仅保留音频功能

智能眼镜正逐渐融入人们的日常生活，查看通知、拨打电话等操作无需掏出手机，确实带来了不少便利。然而一旦坐到方向盘后，这种便利便可能迅速变成安全隐患，尤其是配备显示屏的款式。但这并不意味着你上车后就必须摘下Meta Ray-Ban Display眼镜。

遗憾的是，Meta Display眼镜并非为提供实时驾驶导航而设计。但如果你希望在车内继续使用它又不想分心，只需将其切换至“仅音频”模式即可。开启该模式后，眼镜显示屏会完全关闭，相当于变成了一副普通的Meta Ray-Ban AI眼镜。你仍然可以通过免提音频拨打电话、使用快捷语音指令，但没有任何视觉干扰。

设置驾驶检测功能非常简单，而且无需每次上车都手动切换模式。Meta AI应用内置了驾驶检测功能，可以自动完成这一切。开启后，眼镜会通过内置传感器判断你是否处于行驶中的车辆内。一旦识别出你正在驾驶，便会自动关闭显示屏。

设置过程只需几秒钟：在手机上打开Meta AI应用，进入“设置”，选择你的眼镜并点击“设备设置”，然后开启“仅音频”并将“驾驶检测”切换为激活状态即可。剩下的交给眼镜自动处理。当你到达目的地并下车后，显示屏会自动重新开启。

Meta AI应用在启用该功能前可能会要求特殊权限，因为应用还需要访问手机传感器才能正常工作。你也可以随时手动切换模式，只需说“Hey Meta，开启/关闭仅音频”即可。

值得一提的是，Meta眼镜并非为驾驶导航而设计。如果你仍在想能否用Meta眼镜获取驾驶方向，答案是：不能。这款眼镜目前仅支持步行导航，其界面并非为高速移动场景设计，也缺少高速公路驾驶所需的实时路况更新、车道指引和复杂地图功能。驾驶导航还是应该使用手机GPS或车载导航系统。

除了安全方面的考量，使用“仅音频”模式还有其他好处。驾驶时关闭显示屏可以节省电量，以备真正需要时使用。此外，适当远离屏幕和过多的通知也有益身心。

如何在驾驶时使用Meta Display眼镜的纯音频功能

该功能会完全关闭显示屏。

智能眼镜正悄然成为一些人日常生活中的一部分，用来查看通知和拨打电话等。有时候，不用拿起手机就能完成这些操作确实非常方便。但坐到方向盘后面，这种便利很快就会变成让人分心的隐患，尤其是如果你戴的是带内置显示屏的那款。但这并不意味着你一上车就得摘下Meta Ray-Ban Display。

遗憾的是，Meta Display眼镜在设计上并不支持提供实时驾驶导航。但如果你想在车里继续使用它们又不被分心，只需将它们切换到纯音频模式即可。开启该模式后，眼镜上的显示屏会完全关闭。几乎就相当于把它们变成了普通的Meta Ray-Ban AI眼镜。你仍然可以通过免提音频打电话和使用快捷语音指令，但没有任何视觉上的干扰。

在Meta Display眼镜上设置驾驶检测

更改这些设置非常简单，你不必每次上车都记着切换模式。Meta AI应用内置了驾驶检测功能，可以帮你自动完成这一切。开启该功能后，眼镜会利用内置传感器检测你是否在一辆行驶中的车辆里。一旦眼镜判断你正在驾驶，就会自动关闭显示屏。

设置过程只需几秒钟。操作方法：在手机上打开Meta AI应用，进入“设置”，选择你的眼镜，然后点击“设备设置”。在那里打开“纯音频”，并将“驾驶检测”切换为开启状态。剩下的交给眼镜就行。当你到达目的地下车后，显示屏会自动重新开启。

Meta AI应用在启用此功能前可能会向你请求特殊权限。这是因为该应用还需要访问你手机的传感器才能正常工作。如果你愿意，也可以手动切换模式。只需说“Hey Meta，打开/关闭纯音频”即可。

Meta眼镜并非为驾驶导航而设计

如果你还在想能不能用Meta眼镜来做驾驶导航，答案是：不能。这些眼镜目前仅支持步行导航。其界面并非为高速出行而设计，也缺少你在高速公路上所需的实时路况更新、车道指引和复杂地图功能。驾驶导航还是乖乖用手机上的GPS或车载内置导航系统吧。

虽然使用纯音频模式最显而易见的原因是安全，但也有一些其他好处。驾驶时关闭显示屏可以省下一些电量，留到真正需要的时候再用。此外，偶尔远离屏幕和过多的通知总是好事。如果你想进一步了解Meta Display眼镜，可以看看我们的完整评测。

How to use Meta Display glasses while driving with the Audio Only feature
The feature turns off the display entirely.
Smart glasses are quietly becoming part of some people's daily routines for things like checking notifications and making calls. Being able to do that without having to pick up your phone is really useful sometimes. But behind the wheel, that same convenience turns into a distraction fast, especially if you have one of those with a built-in display. But that doesn't mean you have to take off your Meta Ray-Ban Display as soon as you get in the car.
Unfortunately, Meta Display glasses were not designed to provide real-time driving directions. But if you want to keep using them in your car without getting distracted, you just need to switch them to Audio Only mode. With this mode on, the display on the glasses turns off completely. It's almost as if you were turning them into regular Meta Ray-Ban AI glasses. You still have hands-free audio for calls and quick voice commands, but without any visual distractions.
Setting up driving detection on your Meta Display glasses
Changing these settings is quite easy and you don't have to remember to switch modes every time you get in the car. The Meta AI app includes a Driving Detection feature that handles the heavy lifting for you. When the feature is on, the glasses use their internal sensors to detect when you're in a moving vehicle. Once the glasses realize you're driving, they automatically disable the display.
Setting it up only takes a few seconds. To do this, open the Meta AI app on your phone. Go to Settings, select your glasses and tap Device Settings. From there, turn on Audio Only and toggle Driving Detection to active. The glasses will handle the rest. Once you reach your destination and step out of the car, the display will turn back on automatically.
The Meta AI app may ask you for special permission before enabling this feature. That's because the app also needs access to your phone's sensors to work. You can also switch modes manually if you want. Just say "Hey Meta, turn on/off audio only."
Meta glasses were not designed for driving navigation
If you're still wondering whether you can use Meta for driving directions somehow, the answer is no. These glasses currently only support pedestrian navigation. The interface is not really designed for high-speed travel and it lacks the real-time traffic updates, lane guidance and complex mapping you need on the highway. You should probably stick with the GPS on your phone or your car's built-in navigation system for driving directions.
Although safety is the obvious reason to use Audio Only mode, there are some other benefits too. Turning off the display while you drive can save some battery for when you really need it. Besides, it's always good to take a break from screens and excessive notifications. And if you want to learn more about the Meta Display glasses, here's our full review.
