Patent number: 12218944Abstract: Aspects of the present disclosure are directed to group travel between artificial reality (XR) destinations. Currently, users in an artificial reality (XR) experience cannot travel with a group to a specific destination or between destinations (e.g., to and from virtual worlds, levels, applications, etc.). Thus, some implementations assign users within a group in a multiplayer XR experience (e.g., a virtual lobby) a same session identifier. When the users select a destination, some implementations can provide a computing system hosting the destination with the session identifier associated with the users, such that the hosting computing system can ensure that the users travel to the same instance of the destination together. If a user does not already have the destination installed, some implementations can allow the user to acquire access rights to the destination, then travel to the same instance of the destination as the other users.Type: GrantFiled: October 10, 2022Date of Patent: February 4, 2025Assignee: Meta Platform Technologies, LLCInventors: Michael Hadley, Danyang Zhao, Patrick McGartoll, Nicolas Sleiman Machado

Patent number: 12212705Abstract: Aspects of the present disclosure are directed to controlling a sending side of an augmented call based on a receiving user's gaze. Some implementations provide a hologram moderation system in which a receiving user's gaze can control how the system generates a representation of a sending user on a sending side. For example, some implementations can moderate the capture or generation of hologram data representing the sending user when the receiving user isn't focused on the hologram that results from the data. Such moderations can reduce power consumption, bandwidth, heat production, and/or processing power needed by the artificial reality system when the receiving user is not looking at the hologram of the sending user, such as when the sending user is in the receiving user's periphery or outside the receiving user's field-of-view.Type: GrantFiled: June 15, 2022Date of Patent: January 28, 2025Assignee: Meta Platforms Technologies, LLCInventors: Jing Ma, Paul Armistead Hoover, Joshuah Vincent

Patent number: 12205229Abstract: A head-mounted device (HMD) of a first user has a transparent display. The HMD determines location information of a second user relative to the HMD of the first user. The second user is located within a predefined distance of the HMD. The location information identifies a distance and a direction of the second user relative to the HMD. The HMD receives audio content from the second user, generates augmented reality (AR) content based on the audio content, and displays the AR content in the transparent display based on the location information of the second user. The AR content appears coupled to the second user.Type: GrantFiled: December 8, 2022Date of Patent: January 21, 2025Assignee: Meta Platforms Technologies, LLCInventor: Brian Mullins

Patent number: 12200409Abstract: In holographic calling, it is difficult to capture the eyes of a caller due to lighting effects on an artificial reality (XR) headset. However, it can be important to capture the eyes when rendering the caller as they can show emotion, gaze, physical characteristics, etc., that aid in natural communication. Thus, implementations can capture the eyes of the caller using an external image capture device by briefly turning off the lighting effects on the XR headset. Some implementations can trigger the image capture device to capture an image of the eyes by temporal multiplexing in which timers on both the image capture device and the XR headset are synchronized. In other implementations, the image capture device can be an event-based camera that is automatically triggered to capture an image of the eyes based on a detected pixel change caused by deactivation of the lighting effects on the XR headset.Type: GrantFiled: August 26, 2022Date of Patent: January 14, 2025Assignee: Meta Platforms Technologies, LLCInventors: Jean-Charles Bazin, Alexandre Chapiro

ROM instruction authentication and integrity verification for artificial reality security controller
Patent number: 12200130Abstract: Systems, methods, and devices authenticate processor instructions stored by a read-only memory (ROM). In one example, a ROM stores a block of register words. The block of register words includes a first register word specifying an authentication tag and one or more register words that each specify an instruction. A security controller identifies the first register word as specifying the authentication tag and performs authentication of the authentication tag. Upon successfully authenticating the authentication tag, the security controller forwards the register words that each specify instructions to a processor for execution. Upon unsuccessfully authenticating the authentication tag, the security controller blocks the register words that each specify instructions from execution by the processor.Type: GrantFiled: January 7, 2021Date of Patent: January 14, 2025Assignee: Meta Platforms Technologies, LLCInventors: Sudhir Satpathy, Wojciech Stefan Powiertowski, Nagendra Gupta Modadugu, Neeraj Upasani -
Patent number: 12197644Abstract: When a notification is to be shown, an artificial reality notification system can add the notification to a pre-defined location in the user's field of view (e.g., top, side, or bottom) where it stays as a head leashed virtual object until the user's gaze is direct to the notification. When the user's gaze is directed at the notification, the artificial reality notification system can make the notification world locked, allowing the user to move her head to bring the notification to the center of her field of view, move closer to the notification to make it larger, move around the notification to see aspects from different angles, etc. The notification can be dismissed if the user never directs her gaze at it for a first threshold amount of time or when the user looks away from the world-locked version for a second threshold amount of time.Type: GrantFiled: October 17, 2023Date of Patent: January 14, 2025Assignee: Meta Platforms Technologies, LLCInventor: Hayden Schoen
