Walk the independent claim. Meta's grant US11537198B1, "Reconfigurable headset that transitions between virtual reality, augmented reality, and actual reality" (issued December 27, 2022), is a granted patent — the B1 kind code indicates a grant issued without a prior publication. Its CPC tags G06F 3/011 and G06V 20/20 are the AR/VR-interaction and scene-understanding classes, not pure optics, which is the first signal that the invention lives in the control logic, not the lenses.

Claim 1 is a computer-implemented method, and it defines three named configurations precisely. The virtual-reality and augmented-reality configurations both include a computer-generated image; the direct-reality and augmented-reality configurations both include a real-time image of the user's environment. So the claim partitions the experience by what is being shown: pure synthetic content (VR), synthetic content over a live view (AR), and an unobstructed live view (direct reality). The method then (a) identifies a scenario to switch between these configurations, (b) provides the user a notification that includes "an intent to switch," (c) switches according to the scenario, and (d) provides an avatar of the user to a remote device when the configuration has switched to VR. That fourth element is easy to overlook and important: the independent claim is not merely about toggling modes — it ties the transition into VR to surfacing the user as an avatar to a connected remote device, which is the social/telepresence hook.

The dependent claims spell out what "identifying a scenario" means, and they read like a catalogue of passthrough triggers. Claim 2 identifies the scenario by capturing an image of the environment and detecting a potential hazard. Claim 3 does the same from captured audio, detecting an alert. Claim 5 uses multiple inertial motion sensors and recognizes a signal pattern indicative of a hazard. Claim 4 runs the logic the other way — determining that a period of time has lapsed with no alert or hazard and then selecting an intent to switch from AR back into VR. Claim 6 describes the notification as a "through-video image in a portion of a display," i.e. a window of passthrough as the prompt itself; claim 7 requires receiving the user's validation of the intent before switching; claim 8 adds a physical button for the user to pick among the three modes. Read together, the dependents disclose a hazard-aware mediation layer: the headset watches the room with cameras, microphones, and IMUs, decides when immersion is unsafe or unnecessary, warns the wearer, and transitions — sometimes only after the user confirms.

That is a sharper invention than "passthrough." The claim's contribution is the closed loop between environment sensing and immersion level, with the user kept in the loop via notification and optional validation. The independent system claim (claim 10) and the non-transitory medium claim (claim 15) re-cast the same logic, with claim 15 notably requiring both image-based hazard detection and audio-based alert detection together, plus the VR-avatar step — a tighter combination than claim 1.

What it reads on is the mixed-reality headset that blends VR and passthrough AR — the category Meta's Quest Pro and successors target. The framing as a sensor-driven transition is strategically deliberate: it captures the user-facing capability that distinguishes mixed reality from older single-mode devices, and it captures the safety behavior (drop the user back to a live view when the room demands attention) that regulators and users increasingly expect.

It is worth being precise about genealogy. A switchable VR/AR device is not itself new — earlier grants from other companies describe dual-mode headsets. What claim 1 adds is the three-way transition that explicitly includes actual reality, the notification-of-intent step, and the VR-avatar-to-remote-device limitation. The enforceable scope is whatever those limitations recite, not the general concept of mode-switching.

Scope discipline therefore cuts two ways. A headset that achieves passthrough without the recited scenario-identification-and-notification flow — for instance, a manual-only toggle with no hazard detection and no avatar step — may sit outside claim 1. Conversely, a device that watches the environment for hazards, prompts the user, and represents them as an avatar in a remote VR session is walking straight through the middle of these limitations. The defensible elements are the sensing-driven scenario detection, the intent notification, and the avatar handoff, not the bare idea of moving between realities.

It is worth noting how the three independent claims fence the same idea at different breadths, because that shapes how an opponent would attack or design around it. Claim 1 (the method) is the broadest framing of the sensing-to-transition loop plus the VR-avatar step. Claim 10 (the system) builds in the image-based hazard detection as a required element of the processor's operation, narrowing it to a vision-aware device. Claim 15 (the computer-readable medium) is narrower still: it requires both image-based hazard detection and audio-based alert detection together, plus the scenario switch and the VR-avatar handoff in a single recited method. A challenger arguing that one broad claim is anticipated by an earlier dual-mode headset still has to contend with the layered combinations in claims 10 and 15, where the specific multi-sensor mediation and the avatar limitation are knit into the independent scope rather than left to dependents.

Granted status makes US11537198B1 a live consideration for anyone building a mode-transitioning headset, and the breadth of the dependent triggers (vision, audio, inertial, timeout) means a designer cannot easily route around it by swapping one sensor for another. For a strategist, the patent is also a marker of where Meta stakes its mixed-reality claims — not on optics, but on the experience and safety layer of moving between immersion levels, with social presence wired into the VR end of the transition.
