Qualcomm launches wireless AR glasses reference design
Qualcomm has launched its next generation of reference design for augmented reality glasses, its first with a wireless interface.
The Wireless AR Smart Viewer reference design by Goertek in China is based around the Qualcomm 5G XR2 chip with Goertek’s near-ear acoustic module. The design has a 40% thinner profile and a more ergonomically balanced weight distribution for increased comfort.
The two 1920 x 1080 OLED screens come from SeeYA in China and support frame rates up to 90Hz and have a no-motion-blur feature. Dual monochrome cameras and one RGB camera on the smart viewer enable six-degrees of freedom (6DoF) head tracking and hand tracking with gesture recognition to achieve AR precision and simultaneous localization and mapping (SLAM). The XR2 uses the Adreno GPU cores for foveation and eye tracking technology.
The reference design enables a wireless split processing architecture to distribute computing workloads between the smartphone and the AR glass. This provides a latency of under 3ms between the smartphone and AR glass. With the FastConnect 6900 chip the reference design supports Wi-Fi 6 and 6E and Bluetooth connectivity.
The design can be paired with the FastConnect XR Software Suite to allow system integrators and application developers better control and preferential channel access for XR traffic to improve M2R2P (motion-to-render-to-photon) latency, reduce jitter, and avoid unwanted interference.
The design has purpose-built power modes for low power operation, without impacting latency performance. for longer, sustained XR experiences. Through the pairing of premium technology and form factor innovation, Qualcomm Technologies will continue to enable the diverse consumer and enterprise needs to help scale AR to the masses. The is available for select partners, with wider availability expected in the coming months.
