Qualcomm AR Glasses Reference Design Drops the Tether

Qualcomm has revealed its newest AR glasses reference design, which it presents as much as different firms as a blueprint for constructing their very own AR units. The reference design, which supplies us a robust trace on the specs and capabilities of upcoming merchandise, continues to lean on a smartphone to do the heavy compute, however this time relies on a wi-fi design.

Qualcomm’s prior AR glasses reference design was primarily based on the Snapdragon XR1 chip and referred to as for a wired connection between a smartphone and the glasses, permitting the system to separate rendering duties between the 2 units.

Now the corporate’s newest design, primarily based on Snapdragon XR2, takes the wire out of the equation. However as an alternative of going absolutely standalone, the brand new reference design continues to depend on the smartphone to deal with a lot of the heavy rendering, however now does so over a wi-fi connection between the units.

Along with Snapdragon XR2, the AR glasses embrace Qualcomm’s FastConnect 6900 chip which equips it with Wi-Fi 6E and Bluetooth 5.3. The corporate says the chip is designed for “ultra-low latency,” and manages lower than 3ms of latency between the headset and the smartphone. The corporate has additionally introduced XR-specific software program for controlling its FastConnect 6900, permitting system makers to tune the wi-fi visitors between the units to prioritize probably the most time-critical knowledge to be able to scale back situations of lag or jitter as a result of wi-fi interference.

Although a linked smartphone looks as if the obvious use-case, Qualcomm additionally says the glasses may simply as nicely be paired to a Home windows PC or “processing puck.”

Past the additional wi-fi tech, the corporate says the most recent design is 40% thinner than its earlier reference design. The newest model has a 1,920 × 1,080 (2MP) per-eye decision at 90Hz. The microdisplays embrace a ‘no-motion-blur’ characteristic—which feels like a low persistence mode designed to forestall blurring of the picture throughout head motion. A pair of monochrome cameras are used for 6DOF monitoring and an RGB digicam for video or photograph seize. The corporate didn’t point out the system’s field-of-view, so it’s unlikely to be any bigger than the prior reference design at 45° diagonal.

Like its many prior reference designs, Qualcomm isn’t really going to make and promote the AR glasses. As an alternative, it presents up the design and underlying know-how for different firms to make use of as a blueprint to construct their very own units (hopefully utilizing Qualcomm’s chips!). Corporations that construct on Qualcomm’s blueprint often introduce their very own industrial design and customized software program providing; some even customise the {hardware} itself, like utilizing totally different shows or optics.

That makes this AR glasses reference design a fairly good snapshot of the present state of AR glasses that may be mass produced, and a glimpse of what some firms shall be providing within the close to future.

Qualcomm says its newest AR glasses reference design is “accessible for choose companions,” as of right this moment, and plans to make it extra broadly accessible “within the coming months.”
