This month's VR & Augmented Reality activity includes 4 filed patent applications from InterDigital CE Patent Holdings, SAS (1), Niantic (1), Roblox (1), and Sony (1).
The patents cover foundational infrastructure for immersive experiences, from runtime scene modification to cross-platform presence. InterDigital describes technology for translating standardized XR scene data into live game engine updates, while Sony details a system for populating virtual worlds with avatars from other metaverse platforms. Niantic's application covers server architecture that combines crowdsourced AR scan data into unified 3D map tiles, and Roblox describes camera-based facial tracking technology that synchronizes device orientation with avatar head movement.
InterDigital CE Patent Holdings, SAS received 1 patent addressing the challenge of updating 3D scenes in real time without recompiling or rebuilding game engine assets. The system introduces a translation layer that converts standardized scene description patch data, structured as JSON Patch-style operations on glTF or MPEG scene graphs, into commands that game engines can execute at runtime. This approach allows immersive content creators to modify XR environments using industry-standard formats while keeping those updates independent of the underlying engine's native scene representation.
Sony received 1 patent tackling the problem of empty or sparsely populated virtual worlds. When user counts drop below a threshold that creates a "ghost town" effect, the system pulls in avatar representations of users who are currently active in entirely different metaverse platforms and displays them in a visually distinct way within the host environment. This cross-platform presence mechanism differs from spawning scripted NPCs or merging instances within a single platform, instead creating the appearance of social activity by borrowing real users from separate virtual worlds.
Niantic received 1 patent describing server infrastructure that combines spatial scan data submitted by many users into coherent 3D map tiles. The system uses control points as reference anchors and applies an objective function with gradient descent to align and merge sensor data from overlapping scans captured by different devices operating in different coordinate systems. Rather than storing fragmented, device-specific spatial information, the server produces unified map tiles that can be continuously refined as more users contribute scan data, enabling high-fidelity AR experiences at global scale without dedicated scanning hardware.
Roblox received 1 patent focused on synchronizing mobile device orientation with facial landmark tracking to control 3D avatar head movement. The system tracks changes in the user's head position via the device camera while simultaneously monitoring the physical orientation of the device itself, combining both inputs rather than relying on facial tracking alone. The application describes applying only a predetermined percentage of detected facial landmark changes to the avatar's directional orientation, creating a tunable smoothing mechanism that adjusts how responsive the avatar appears to the user's physical movements.
