Steam Frame

Foveated streaming! That's a great idea. Foveated rendering is complicated to implement with current rendering APIs in a way that actually improves performance, but foveated streaming seems like a much easier win that applies to all content automatically. And the dedicated 6 GHz dongle should do a much better job at streaming than typical wifi routers.

It's an ARM Linux PC that presumably gives you root access, in addition to being a VR headset. And it has an SD card slot for storage expansion. Very cool, should be very hackable. Very unlike every other standalone VR headset.

> 2160 x 2160 LCD (per eye) 72-144Hz refresh rate

Roughly equivalent resolution to Quest 3 and less than Vision Pro. This won't be suitable as a monitor replacement for general desktop use. But the price is hopefully low. I'd love to see a high-end option with higher resolution displays in the future, good enough for monitor replacement.

> Monochrome passthrough

So AR is not a focus here, which makes sense. However:

> User accessible front expansion port w/ Dual high speed camera interface (8 lanes @ 2.5Gbps MIPI) / PCIe Gen 4 interface (1-lane)

Full color AR could be done as an optional expansion pack. And I can imagine people might come up with other fun things to put in there. Mouth tracking?

One thing I don't see here is optional tracking pucks for tracking objects or full body tracking. That's something the SteamVR Lighthouse tracking ecosystem had, and the Pico standalone headset also has it.

More detail from the LTT video: Apparently it can run Android APKs too? Quest compatibility layer maybe? There's an optional accessory kit that adds a top strap (I'm surprised it isn't standard) and palm straps that enable using the controllers in the style of the Valve Index's "knuckles" controllers.

The real limiting factor is more likely to be having a large headset on your face for an extended period of time, combined with a battery that isn't meant for all-day use. The resolution is fine. We went decades with low resolution monitors. Just zoom in or bring it closer.

The battery isn't an issue if you're stationary, you can plug it in.

The resolution is a major problem. Old-school monitors used old-school OSes that did rendering suitable for the displays of the time. For example, anti-aliased text was not typically used for a long time. This meant that text on screen was blocky, but sharp. Very readable. You can't do this on a VR headset, because the pixels on your virtual screen don't precisely correspond with the pixels in the headset's displays. It's inevitably scaled and shifted, making it blurry.

There's also the issue that these things have to compete with what's available now. I use my Vision Pro as a monitor replacement sometimes. But it'll never be a full-time replacement, because the modern 4k displays I have are substantially clearer. And that's a headset with ~2x the resolution of this one.
