Meta Explains Tech Behind Its Aria Gen 2 Glasses


Earlier this 12 months, Meta introduced Aria Gen 2 as a research-focussed wearable system and the successor to 2020’s Mission Aria. The corporate has now taken a deep dive into the know-how which powers the second technology of the AI and ML-powered sensible glasses. It comes with plenty of enhancements in comparison with the primary technology mannequin, that includes upgraded sensors, hand and eye monitoring methods, and a photoplethysmography (PPG) sensor similar to the Apple Watch.

According to Meta, the Aria Gen 2 maintains its light-weight design, weighing between 74-76g. The sensible glasses are mentioned to boast improved wearability and luxury, with folding arms for extra handy storage and transport. It’s accessible in a complete of eight measurement choices for various face morphologies, accounting for components like head width and nostril bridge variations.

The sensible glasses’ world shutter digital camera sensor can seize a excessive dynamic vary of 120dB in comparison with 70dB on the primary technology mannequin. Meta claims this helps the pc imaginative and prescient work throughout diverse lighting situations. Additional, it has been outfitted with 4 pc imaginative and prescient (CV) cameras with a wider subject of view to energy superior 3D hand and eye-tracking capabilities. The Meta Aria Gen 2 additionally will increase stereo overlap from 35-degree on the first-gen mannequin to 80-degree. That is mentioned to facilitate stereo-based basis and fashions which enhance spatial consciousness and depth notion.

The standout options on the sensible glasses are their hand and eye monitoring capabilities. They leverage a camera-based eye-tracking system that tracks the wearer’s gaze and offers info comparable to gaze per eye, vergence level, blink detection, and pupil diameter. Meta says this could probably enhance human-computer interplay and perceive the wearer’s visible consideration. In the meantime, the Aria Gen 2 can observe a hand in 3D area and produce hand-joint poses within the body of reference. As per the corporate, these allow exact guide labelling of datasets for functions comparable to dexterous robotic hand manipulation.

Aria Gen 2 Glasses include the next {hardware}:

  • 12-megapixel RGB digital camera
  • 4 Laptop Imaginative and prescient cameras
  • Ambient gentle sensor
  • Seven spatial microphones
  • Accelerometer
  • GNSS
  • Barometer
  • Stereo audio system
  • Privateness swap and quantity management
  • USB Sort-C port

Aria Gen 2 additionally takes benefit of Visible Inertial Odometry (VIO) to detect glasses in six levels of freedom (6DOF) inside a spatial body of reference. It’s mentioned to assist in contextual AI and robotics by permitting for navigation and mapping of the setting. These options are powered by superior on-device machine notion algorithms that run on Meta’s customized coprocessor.

The sensible glasses carry an improved suite of sensors. This features a calibrated ambient gentle sensor, which has higher management algorithms which work even at low body charges. It comes with an ultraviolet mode that may distinguish between color and indoor lighting. In the meantime, there is a contact microphone embedded within the nostril pad of the sensible glasses for capturing audio. The nostril pad additionally includes a PPG sensor that may precisely detect the wearer’s coronary heart price.

Regardless of these upgrades, the Aria Gen 2 Glasses are claimed to serve solely as a “testbed” within the growth of superior sensible glasses they usually will not be commercially accessible. It’s geared toward researchers and Meta’s companions, corporations like BMW and universities together with Carnegie Mellon, IIIT Hyderabad, and the College of Bristol.
