Today, during the XR edition of The Android Show, Google showed off a bunch of updates and new features headed to its mixed reality OS. And while most of the news was aimed at developers, I got a chance to demo some of the platform's expanded capabilities on a range of hardware including Samsung's Galaxy XR headset, two different reference designs and an early version of Xreal's Project Aura smart glasses and I came away rather impressed. So here's a rundown of what I saw and how it will impact the rapidly growing ecosystem of head-mounted displays.
First up was one of Google's reference design smart glasses with a single waveguide RGB display built into its right lens. I've included a picture of it here, but try not to read too deeply into its design or aesthetics, as this device is meant to be a testbed for Android XR features and not an early look at upcoming models.

After putting them on, I was able to ask Gemini to play some tunes on YouTube Music before answering a call simply by tapping on the touchpad built into the right side of the frames. And because the reference model also had onboard world-facing cameras, I could easily share my view with the person on the other end of the line.

Naturally, I was curious about how glasses had the bandwidth to do all this, because in normal use, they rely on a Bluetooth or Bluetooth LE connection. When asked, Max Spear, Group Product Manager for XR, shared that depending on the situation, the device can seamlessly switch between both Bluetooth and Wi-Fi, which was rather impressive because I couldn't even detect when that transition happened. Spear also noted that one of Google's focuses for Android XR is making it easier for developers to port over the apps people already know and love.
This means for devices like the reference design I wore that feature a built-in display (or displays), the OS actually uses the same code meant for standard Android notifications (like quick replies) to create a minimalist UI instead of forcing app makers to update each piece of software to be compliant with an ever-increasing number of devices. Alternatively, for models that are super lightweight and rely strictly on speakers (like Bose Frames), Google has also designed Android XR so that you only need mics and voice controls to access a wide variety of apps without the need for visual menus.
