Patent number: 11967020Abstract: A distributed, cross reality system efficiently and accurately compares location information that includes image frames. Each of the frames may be represented as a numeric descriptor that enables identification of frames with similar content. The resolution of the descriptors may vary for different computing devices in the distributed system based on degree of ambiguity in image comparisons and/or computing resources for the device. A descriptor computed for a cloud-based component operating on maps of large areas that can result in ambiguous identification of multiple image frames may use high resolution descriptors. High resolution descriptors reduce computationally intensive disambiguation processing. A portable device, which is more likely to operate on smaller maps and less likely to have the computational resources to compute a high resolution descriptor, may use a lower resolution descriptor.Type: GrantFiled: December 20, 2022Date of Patent: April 23, 2024Assignee: Magic Leap, Inc.Inventors: Elad Joseph, Gal Braun, Ali Shahrokni

Publication number: 20240077943Abstract: A display system can include a head-mounted display configured to project light to an eye of a user to display virtual image content at different amounts of divergence and collimation. The display system can include an inward-facing imaging system possibly comprising a plurality of cameras that image the user's eye and glints for thereon and processing electronics that are in communication with the inward-facing imaging system and that are configured to obtain an estimate of a center of rotation of the user's eye using cornea data derived from the glint images. The display system may render virtual image content with a render camera positioned at the determined position of the center of rotation of said eye.Type: ApplicationFiled: November 7, 2023Publication date: March 7, 2024Inventors: David Cohen, Elad Joseph, Ron Nisim Ferens, Eyal Preter, Eitan Shmuel Bar-On, Giora Yahav

Publication number: 20230058154Abstract: A method includes a computing system associated with a first artificial-reality device accessing sensor data of a real environment, generating a first plurality of feature descriptors for the real environment, and generating a second plurality of feature descriptors for the real environment based on the first plurality of feature descriptors, wherein the second plurality of feature descriptors have lower detail than the first plurality of feature descriptors. The computing system may further cause the first plurality of feature descriptors to be transmitted using a wireless connection, wherein the transmitted first plurality of feature descriptors are configured to be converted into a third plurality of feature descriptors different from the second plurality of feature descriptors. The third plurality of feature descriptors are configured to be used by a second artificial-reality device for tracking the real environment.Type: ApplicationFiled: August 19, 2021Publication date: February 23, 2023Inventors: Evyatar Bluzer, Elad Joseph, Ezri Joseph Sonn, Shanghsuan Tsai

Publication number: 20210302587Abstract: Techniques are disclosed for operating a time-of-flight (TOF) sensor. The TOF may be operated in a low power mode by repeatedly performing a low power mode sequence, which may include performing a depth frame by emitting light pulses, detecting reflected light pulses, and computing a depth map based on the detected reflected light pulses. Performing the low power mode sequence may also include performing an amplitude frame at least one time by emitting a light pulse, detecting a reflected light pulse, and computing an amplitude map based on the detected reflected light pulse. In response to determining that an activation condition is satisfied, the TOF may be switched to operate in a high accuracy mode by repeatedly performing a high accuracy mode sequence, which may include performing the depth frame multiple times .Type: ApplicationFiled: March 23, 2021Publication date: September 30, 2021Applicant: Magic Leap, Inc.Inventors: David Cohen, Elad Joseph, Eyal Preter, Paul Lacey, Koon Keong Shee, Evyatar Bluzer
