I think it’s great for my Deck but, that will indeed be a problem. The headset contains only the sensors and display systems but, none of the logic circuitry to “pin” displays. Including that would increase the price a good deal.
It is pretty narrow but also what makes it work, IMO. I don’t have them for immersion but for display replacement. The narrow field of view lets the 1080p display have nearly 0 screen door effect. Plus, the birdbath optics are really cheap compared to waveguides or fancy lenses in VR headsets.
That’s basically what I got. Xreal Air (formerly Nreal until a C&D from Epic). 1080p per eye and something like 49PPD with a 45° FOV. Tracking is 6DOF and requires software on the host (only complaint) and connectivity is via a USB-C cable (uses DP alt mode).
It’s nearly as “dumb” as an HMD can get. From the teardowns that I’ve seen, it’s really just got an MCU, a GPIO expander, a 6DOF chip, and the displays + drivers. And I love that about it. No batteries or anything to worry about.
