Qualcomm has revealed its latest AR glasses reference design, which it offers up to other companies as a blueprint for building their own AR devices. The reference design, which gives us a strong hint at the specs and capabilities of upcoming products, continues to lean on a smartphone to do the heavy compute, but this time is based on a wireless design. Qualcomm’s prior AR glasses reference design was based on the Snapdragon XR1 chip and called for a wired connection between a smartphone and the glasses, allowing the system to split rendering tasks between the two devices.
Now the company’s latest design, based on Snapdragon XR2, takes the wire out of the equation. But instead of going fully standalone, the new reference design continues to rely on the smartphone to handle most of the heavy rendering, but now does so over a wireless connection between the devices. In addition to Snapdragon XR2, the AR glasses include Qualcomm’s FastConnect 6900 chip which equips it with Wi-Fi 6E and Bluetooth 5.3. The company says the chip is designed for ultra-low latency and manages less than 3ms of latency between the headset and the smartphone.
