Patent number: 11972040Abstract: A virtual space configuration system of an artificial reality system can detect a user posture and provide various corresponding customizations of the system's virtual space. The virtual space configuration system can, when a user is in a seated posture, provide for seated virtual space customizations. In various implementations, these customizations can include allowing adjustment of a floor height; setting a flag that can be surfaced to applications to adjust the applications' mechanics for seated users; customizing display of virtual space boundaries when in seated mode to be less intrusive; providing options to detect when a user leaves seated mode and trigger corresponding actions; provide a passthrough workspace area allowing a user to interact with certain real-world objects naturally without having to remove a virtual reality headset; or automatically determining virtual space dimensions for seated users.Type: GrantFiled: January 11, 2023Date of Patent: April 30, 2024Assignee: Meta Platforms Technologies, LLCInventors: Samuel Alan Johnson, Shaik Shabnam Nizamudeen Basha, Mahdi Salmani Rahimi, Benjamin Antoine Georges Lefaudeux

Publication number: 20240062492Abstract: The disclosed artificial reality system can provide a user self representation in an artificial reality environment based on a self portion from an image of the user. The artificial reality system can generate the self representation by applying a machine learning model to classify the self portion of the image. The machine learning model can be trained to identify self portions in images based on a set of training images, with portions tagged as either depicting a user from a self-perspective or not. The artificial reality system can display the self portion as a self representation in the artificial reality environment by positioning them in the artificial reality environment relative to the user's perspective in the artificial reality environment. The artificial reality system can also identify movements of the user and can adjust the self representation to match the user's movement, providing more accurate self representations.Type: ApplicationFiled: October 30, 2023Publication date: February 22, 2024Inventors: James Allan BOOTH, Mahdi SALMANI RAHIMI, Gioacchino NORIS

Publication number: 20230245499Abstract: A computing system may receive an image captured by a camera, and determine based on (1) one or more regions in the image that include a portion of a body of a user, and (2) a camera pose of the camera, a three-dimensional volume constraint that stems from the camera pose in which an elbow of the user is likely to be located. The system may infer, based on at least the three-dimensional volume constraint, an elbow pose of the user, wherein the elbow pose includes a location associated with an elbow of the user in three-dimensional space. The system may determine the location associated with the elbow is outside the three-dimensional volume constraint, and in response to the determination, adjust the inferred elbow pose. The system may generate, based on the adjusted elbow pose, a body pose of the user that includes at least the adjusted elbow pose.Type: ApplicationFiled: April 6, 2023Publication date: August 3, 2023Inventors: Samuel Alan Johnson, Mahdi Salmani Rahimi, Benjamin Antoine Georges Lefaudeux, Kishore Venkateshan

Patent number: 11651625Abstract: A computing system may determine a head pose and a wrist pose of a user based on sensor data captured by a head-mounted device. The computing system may further receive an image captured by a camera of the head-mounted device that includes at least portion of the body of the user. Using this image, the computing system may determine one or more regions in the image that correspond to the body of the user, and determine, based on these regions and a camera pose of the camera, a three-dimensional volume constraint in which an elbow of the user is likely to be located when the image was captured. From this information, the computing system may utilize the head pose, the wrist pose, and the three-dimensional volume constraint to infer a body pose of the user that includes at least an inferred elbow pose associated with the user.Type: GrantFiled: September 17, 2020Date of Patent: May 16, 2023Assignee: Meta Platforms Technologies, LLCInventors: Samuel Alan Johnson, Mahdi Salmani Rahimi, Benjamin Antoine Georges Lefaudeux, Kishore Venkateshan

Patent number: 11335077Abstract: A method includes receiving an image of a real environment using a camera worn by a user, and determining a portion of the image that comprises an object of interest. Based on the portion of the image that comprises the object of interest, a surface representing the object of interest is generated. Depth measurements of the real environment corresponding to the portion of the image comprising the object of interest are received and used to determine a depth of the surface representing the object of interest. The surface is posed in a coordinate system corresponding to the real environment based on the depth of the surface and a visibility of a virtual object is determined relative to the object of interest by comparing a model of the virtual object with the surface. The output image is generated based on the determined visibility of the virtual object.Type: GrantFiled: March 19, 2021Date of Patent: May 17, 2022Assignee: Facebook Technologies, LLC.Inventors: Mahdi Salmani Rahimi, Gregory Mayo Daly, Gian Diego Tipaldi, Alexander Sorkine Hornung, Mark David Strachan
