Meta公司推出的Aria Gen 2智能眼镜，作为其“研究眼镜”，集成了众多前沿技术。虽然短期内不会向公众开放，但其技术可能应用于Meta的其他项目。这款眼镜配备了多种传感器，包括用于眼球追踪的摄像头、计算机视觉摄像头、空间麦克风、环境光传感器、气压计、心率监测器和立体声扬声器。Aria Gen 2的特点在于其轻巧的设计和强大的功能，能够实现3D手部和物体追踪，以及精确的心率监测。Meta计划在CVPR会议上展示这款眼镜，展示其在智能眼镜领域的领先地位，引发了人们对未来智能眼镜发展的期待。

👓 **多摄像头系统:** Aria Gen 2配备了一个用于眼球追踪的摄像头和四个计算机视觉摄像头，与第一代相比，视野更广，重叠区域更大，从而实现了更先进的3D手部和物体追踪。

💡 **环境光感应:** 新的环境光传感器，具有紫外线模式，能够区分室内和室外照明，辅助计算机视觉和处理，提升了眼镜的智能化程度。

📡 **SubGHz无线电技术:** 采用SubGHz无线电技术，用于广播时间信息，从而对齐时间并最大限度地减少与其他Aria Gen 2设备或支持该技术的兼容设备之间的延迟。

❤️ **健康监测:** 集成在鼻托中的光电容积脉搏波 (PPG) 传感器，使眼镜能够跟踪佩戴者的心率，为健康监测提供了新的可能性。

📅 **未来应用:** Meta计划在今年晚些时候开放与Aria Gen 2配合使用的应用程序，并邀请研究人员试用该技术，这预示着智能眼镜的应用前景广阔。

Meta's got a pair of smart glasses that are so packed with bleeding edge tech, they truly deserve the "smart" moniker.

Announced earlier this year, the Aria Gen 2 are Meta's "research glasses," meaning they probably won't be available to the general public any time soon. However, the technologies used will probably bleed into Meta's other projects like Orion. In a new blog post Wednesday, Meta revealed some of the capabilities it managed to build into these fairly regular-looking glasses.

The Aria Gen 2 glasses are equipped with an array of cameras, including one for eye-tracking and four computer vision cameras, seven spatial mics, a barrage of sensors including an ambient light sensor, a barometer, a heart rate monitor, and stereo speakers. The glasses themselves are fairly lightweight, weighing 74 to 76 grams, depending on size.

Meta puts all that hardware to good use. The company says the four computer vision cameras produce a wider field of view and enable advanced 3D hand and object tracking. The new ambient light sensor also aids computer vision and processing, as its ultraviolet mode can distinguish between indoor and outdoor lighting.

The company says it uses SubGHz radio technology to broadcast timing information, so that it can align time and minimize delay between other Aria Gen 2 devices or compatible devices that support this tech.

The glasses also have an advanced eye tracking system that knows when the wearer is blinking or when their pupils dilate. And the photoplethysmography (PPG) sensor, built into the nosepad, enables the glasses to track the wearer's heart rate.

Meta says it will open up applications that work with Aria Gen 2 "later this year," and researchers who'd like to try out the tech can sign up for the Aria Gen 2 interest list.

The advances listed above are notable as other manufacturers, including Apple, reportedly race to build their own version of lightweight smart glasses. Judging by the work that Meta's engineers have put into the Aria Gen 2, Apple will have to push hard to match or surpass them.

We'll probably find out more about the Aria Gen 2 smart glasses in a week, as Meta plans to showcase them during the Computer Vision and Pattern Recognition Conference (CVPR) which starts June 11 in Nashville, Tennessee.
