Patent number: 12293029Abstract: Head-mounted augmented reality (AR) devices can track pose of a wearer's head to provide a three-dimensional virtual representation of objects in the wearer's environment. An electromagnetic (EM) tracking system can track head or body pose. A handheld user input device can include an EM emitter that generates an EM field, and the head-mounted AR device can include an EM sensor that senses the EM field (e.g., for determining head pose). The generated EM field may be distorted due to nearby electrical conductors or ferromagnetic materials, which may lead to error in the determined pose. Systems and methods are disclosed that measure the degree of EM distortion, as well as correct for the EM distortion. The EM distortion correction may be performed in real time by the EM tracking system without the need for additional data from imaging cameras or other sensors.Type: GrantFiled: October 19, 2021Date of Patent: May 6, 2025Assignee: Magic Leap, Inc.Inventor: Richmond B.

Patent number: 12283011Abstract: A cross reality system enables any of multiple devices to efficiently and accurately access previously persisted maps of very large scale environments and render virtual content specified in relation to those maps. The cross reality system may build a persisted map, which may be in canonical form, by merging tracking maps from the multiple devices. A map merge process determines mergibility of a tracking map with a canonical map and merges a tracking map with a canonical map in accordance with mergibility criteria, such as, when a gravity direction of the tracking map aligns with a gravity direction of the canonical map. Refraining from merging maps if the orientation of the tracking map with respect to gravity is not preserved avoids distortions in persisted maps and results in multiple devices, which may use the maps to determine their locations, to present more realistic and immersive experiences for their users.Type: GrantFiled: August 28, 2023Date of Patent: April 22, 2025Assignee: Magic Leap, Inc.Inventors: Miguel Andres Granados Velasquez, Javier Victorio Gomez Gonzalez, Mukta Prasad, Eran Guendelman, Ali Shahrokni, Ashwin Swaminathan

Patent number: 12283010Abstract: An augmented reality (AR) display device can display a virtual assistant character that interacts with the user of the AR device. The virtual assistant may be represented by a robot (or other) avatar that assists the user with contextual objects and suggestions depending on what virtual content the user is interacting with. Animated images may be displayed above the robot's head to display its intents to the user. For example, the robot can run up to a menu and suggest an action and show the animated images. The robot can materialize virtual objects that appear on its hands. The user can remove such an object from the robot's hands and place it in the environment. If the user does not interact with the object, the robot can dematerialize it.

Patent number: 12283012Abstract: A cross reality system enables any of multiple devices to efficiently access previously stored maps. Both stored maps and tracking maps used by portable devices may have any of multiple types of location metadata associated with them. The location metadata may be used to select a set of candidate maps for operations, such as localization or map merge, that involve finding a match between a location defined by location information from a portable device and any of a number of previously stored maps. The types of location metadata may prioritized for use in selecting the subset. To aid in selection of candidate maps, a universe of stored maps may be indexed based on geo-location information. A cross reality platform may update that index as it interacts with devices that supply geo-location information in connection with location information and may propagate that geo-location information to devices that do not supply it.Type: GrantFiled: November 15, 2023Date of Patent: April 22, 2025Assignee: Magic Leap, Inc.Inventors: Xuan Zhao, Christian Ivan Robert Moore, Sen Lin, Ali Shahrokni, Ashwin Swaminathan
