Patent number: 11978159Abstract: A cross reality system that provides an immersive user experience by storing persistent spatial information about the physical world that one or multiple user devices can access to determine position within the physical world and that applications can access to specify the position of virtual objects within the physical world. Persistent spatial information enables users to have a shared virtual, as well as physical, experience when interacting with the cross reality system. Further, persistent spatial information may be used in maps of the physical world, enabling one or multiple devices to access and localize into previously stored maps, reducing the need to map a physical space before using the cross reality system in it. Persistent spatial information may be stored as persistent coordinate frames, which may include a transformation relative to a reference orientation and information derived from images in a location corresponding to the persistent coordinate frame.Type: GrantFiled: December 3, 2021Date of Patent: May 7, 2024Assignee: Magic Leap, Inc.Inventors: Anush Mohan, Rafael Domingos Torres, Daniel Olshansky, Samuel A.

Publication number: 20230209373Abstract: A cross reality system enables any of multiple devices to efficiently and accurately access previously stored maps and render virtual content specified in relation to those maps. Both stored maps and tracking maps used by portable devices may have wireless fingerprints associated with them. The portable devices may maintain wireless fingerprints based on wireless scans performed repetitively, based on one or more trigger conditions, as the devices move around the physical world. The wireless information obtained from these scans may be used to create or update wireless fingerprints associated with locations in a tracking map on the devices. One or more of these wireless fingerprints may be used when a previously stored map is to be selected based on its coverage of an area in which the portable device is operating. Maintaining wireless fingerprints in this way provides a reliable and low latency mechanism for performing map-related operations.Type: ApplicationFiled: March 6, 2023Publication date: June 29, 2023Applicant: Magic Leap, Inc.Inventors: Gilboa Shveki, Ben Weisbih, Ofer Kapota, Rafael Domingos Torres, Daniel Olshansky, Joel David Holder

Publication number: 20230127303Abstract: A cross reality system enables any of multiple devices to efficiently and accurately access previously stored maps and render virtual content specified in relation to those maps. The cross reality system may include a cloud-based localization service that responds to requests from devices to localize with respect to a stored map. The request may include one or more sets of feature descriptors extracted from an image of the physical world around the device. Those features may be posed relative to a coordinate frame used by the local device. The localization service may identify one or more stored maps with a matching set of features. Based on a transformation required to align the features from the device with the matching set of features, the localization service may compute and return to the device a transformation to relate its local coordinate frame to a coordinate frame of the stored map.Type: ApplicationFiled: December 20, 2022Publication date: April 27, 2023Applicant: Magic Leap, Inc.Inventors: Ali Shahrokni, Daniel Olshansky, Xuan Zhao, Rafael Domingos Torres, Joel David Holder, Keng-Sheng Lin, Ashwin Swaminathan, Anush Mohan

Patent number: 11386629Abstract: An augmented reality viewing system is described. A local coordinate frame of local content is transformed to a world coordinate frame. A further transformation is made to a head coordinate frame and a further transformation is made to a camera coordinate frame that includes all pupil positions of an eye. One or more users may interact in separate sessions with a viewing system. If a canonical map is available, the earlier map is downloaded onto a viewing device of a user. The viewing device then generates another map and localizes the subsequent map to the canonical map.Type: GrantFiled: March 22, 2021Date of Patent: July 12, 2022Assignee: Magic Leap, Inc.Inventors: Jeremy Dwayne Miranda, Rafael Domingos Torres, Daniel Olshansky, Anush Mohan, Robert Blake Taylor, Samuel A.

Publication number: 20220130120Abstract: A cross reality system enables any of multiple types of devices to efficiently and accurately access previously stored maps and render virtual content specified in relation to those maps. The cross reality system may include a cloud-based localization service that responds to requests from devices to localize with respect to a stored map. Devices of any type, with native hardware and software configured for augmented reality operations may be configured to work with the cross reality system by incorporating components that interface between the native AR framework of the device and the cloud-based localization service. These components may present position information about the device in a format recognized by the localization service. Additionally, these components may filter or otherwise process perception data provided by the native AR framework to increase the accuracy of localization.Type: ApplicationFiled: January 7, 2022Publication date: April 28, 2022Applicant: Magic Leap, Inc.Inventors: Xuan Zhao, Ali Shahrokni, Daniel Olshansky, Christian Ivan Robert Moore, Rafael Domingos Torres, Joel David Holder
