The Aria Gen 2 is designed for comfort and is lightweight at 74-76g. It has foldable arms like regular glasses, making it easy to store and carry. It also comes in eight sizes to accommodate a wide range of face shapes, taking into account variations in head width and nose bridge.
The camera features four computer vision (CV) cameras for tracking hands and objects, and one 12MP RGB camera for high-quality image capture. The CV camera's angle of view is 80 degrees, a significant improvement from the Gen 1's 35 degrees, which enables the generation of high-quality depth maps.
The Aria Gen 2 CV camera supports a high dynamic range (HDR) of 120 dB, and in the comparison movie below, the Aria Gen 2 CV camera (left) does not overexpose even when shooting bright lighting, and you can see that the filament inside the light bulb is clearly visible.
And the depth map created by Aria Gen 2 looks like the movie below.
Additionally, the device is equipped with an eye tracking camera that tracks the wearer's gaze with high precision, providing detailed information such as binocular gaze, blink detection, pupil center estimation, pupil diameter, and corneal center.
The device is also packed with sensors, with seven spatial microphones for high-quality voice capture. The contact microphone is built into the nose pad, so it can pick up the user's voice even in noisy environments. Below is a video comparing the sound quality of a voice spoken in front of the blower with that of a regular microphone and the Aria Gen 2's contact microphone.
The nose pads are also equipped with a photoplethysmography (PPG) sensor that can measure the wearer's heart rate.
Additional features include Device Time Synchronization, where an on-board hardware solution utilizes SubGHz wireless technology to broadcast timing information to enable precise time synchronization with other Aria Gen 2 devices and compatible hardware, enabling tasks like distributed capture and write from multiple Aria Gen 2 devices.
The interface includes a USB-C port, an LED indicator, a privacy switch, volume control, and stereo speakers.
Applications for Aria Gen 2 are scheduled to open in the second half of 2025. Applications for the Aria Research Kit with Aria Gen 1 glasses are still being accepted. In addition, an interactive demo of the Aria Gen 2 glasses will be exhibited at CVPR 2025 , which will be held in Nashville, Tennessee, USA in June 2025.
