The Snapdragon AR2 is Qualcomm Technologies' first system-on-chip (SoC) solution designed specifically for headworn AR devices. Its distributed processing architecture enables the development of AR smart viewers that are powerful, yet slim and energy-efficient. Combining the groundbreaking design of Snapdragon AR2 and Goertek's leading design and development capabilities coupled with its cumulative experience and investment in the AR field, the new AR viewer reference design is lighter and thinner, with a total weight of just under 100g. With lightning fast Wi-Fi 7 connectivity, the design can reduce the latency between the AR glasses and the host device (smartphone) to less than 2 ms. It consumes less energy, and supports SLAM and environmental sensing, 6 DoF (degrees of freedom) and will support the Snapdragon Spaces™ XR Developer Platform. The compact and lightweight appearance, combined with its exceptional performance, makes the reference design truly wearable for a variety of applications including mobile office, teleconferencing, gaming and entertainment, learning, and training. At this time, the reference design is available as a companion device to Snapdragon 8-powered smartphones that are Snapdragon Spaces ready, with additional platforms for mobile, PC and other computing devices to be supported in the future.

        This reference design is a continuation of the Snapdragon XR2-based AR glasses reference design that Goertek unveiled in June 2022. With a 12.8% reduction in frame thickness and a 30% reduction in leg height, these engineering improvements allow the design to be more resemblant of genuine spectacles. The carbon fiber and magnesium-lithium alloy make the housing lighter while still maintaining exceptional thermal performance. With the unique flexible hinge design, the glasses will automatically return to the folded position once removed from the head, while the temples can be bent into position to fit different face sizes.

        The reference design makes use of a new generation of free-form modules for optics, which improves visual acuity with a 38° display FOV and a wider viewing angle, increasing the vertical field of view by 50%. To better accommodate the requirements of various indoor and outdoor as well as daytime and nighttime scenarios, the maximum brightness has been increased to 1500 nits. In a major step up in terms of enhanced visual performance, the reference design also features a handy magnetic removal and replacement lens feature that enables the user to easily swap out lenses with various light transmission rates (using high transmission rate lenses in bright light and low transmission rate lenses in dim light) and supports lenses with various degrees of myopia adjustment. The reference design will also be available in future versions with other optical configurations. The reference design uses Goertek's proprietary near-ear stereo acoustic solution, which strikes a balance between sound quality and privacy while optimizing the noise reduction algorithm to improve voice recognition and deliver an unmatched listening experience.
