Meta: Aria Gen 2, the smart glasses that go beyond the smartphone

Aria Gen 2 is designed to be more comfortable than the previous version. Thanks to the new design, the new glasses fit more faces. Improved comfort: the new devices are lighter, have foldable arms and are more convenient to carry.

In terms of technical innovations, the light sensitivity of the integrated cameras is increased and the field of vision is extended. The eye tracking system is able to detect the gaze in great detail, calculating the direction of each eye, where they converge, the movement of the eyelids and even the diameter and centre of the pupil.

Gesture tracking also covers, for example, hand movements. It analyses the position of joints in three-dimensional space and provides extremely important data for creating training sets for robotics, such as in the field of intelligent prosthetics.

A microphone is positioned at the nose pad to capture audio more easily, even in noisy environments. The new version of the glasses also features new systems for tracking and monitoring gestures and eye movements. Thus the instrument is able to respond more reactively to the user's intentions to increase the accuracy of the data collected.

A new feature is the integration of low-frequency radio technology into the device, which enables time alignment with other compatible devices with sub-millisecond accuracy. A customised low-power coprocessor is then integrated into the glasses, which handles advanced perception algorithms in real time. These algorithms continuously analyse how the user interacts with his or her surroundings.

One of the most advanced aspects of Aria Gen 2 is its ability to locate itself in space through a technique that combines motion and image data to track the position of the eyewear. This enables precise mapping of the environment and makes it possible to use it in autonomous or robotic navigation scenarios, even in the absence of GPS.
