Certain aspects of the present disclosure provide a method for operating a wearable display device. The method includes determining a position of the wearable display device based on a motion sensor. The method includes rendering, by a graphics processing unit, an image based on the determined position. The method includes determining a first updated position of the wearable display device based on the motion sensor. The method includes warping, by a warp engine, a first portion of the rendered image based on the first updated position. The method includes displaying the warped first portion of the rendered image on a display of the wearable display device.

Abstract: Systems, methods, and non-transitory media are provided for generating obfuscated control interfaces for extended reality (XR) experiences. An example method can include determining a pose of an XR device within a mapped scene of a physical environment associated with the XR device; rendering a virtual control interface within the mapped scene according to a configuration including a first size, a first position relative to the pose of the XR device, a first ordering of input elements, and/or a first number of input elements; and adjusting the configuration of the virtual control interface based on a privacy characteristic of data associated with the virtual control interface and/or characteristics of the physical environment associated with the XR device, the adjusted configuration including a second size, a second ordering of input elements, a second number of input elements, and/or a second position relative to the pose of the XR device and/or first position.

Abstract: Systems, methods, and non-transitory media are provided for using a wearable ring device for extended reality (XR) functionalities. An example wearable device can include a structure defining a receiving space configured to receive a finger associated with a user, the structure including a first surface configured to contact the finger received via the receiving space; one or more sensors integrated into the structure, the one or more sensors being configured to detect a rotation of at least a portion of the structure about a longitudinal axis of the receiving space; and a wireless transmitter configured to send, to an electronic device, data based on the rotation.

Abstract: Systems and methods relate to safely and efficiently operating a multiprocessing system involving cooperation of a first processor and a second processor. For example, with regard to a first process of a first processor to be handed off to a second processor for execution, a first memory protection domain (PD) is created in a common memory, the first memory PD corresponding to the first process. The first memory PD is extended between the first processor and the second processor such that the second processor is enabled to execute the first process within the first memory PD. With regard to the first process, accesses to the common memory by the first and second processors are limited to the first memory PD, which ensures safety of the first and second processors from one another.
Abstract translation: 系统和方法涉及安全和有效地操作涉及第一处理器和第二处理器的协作的多处理系统。 例如，关于要切换到第二处理器进行执行的第一处理器的第一处理，在公共存储器中创建第一存储器保护域（PD），第一存储器对应于第一处理。 第一存储器PD在第一处理器和第二处理器之间延伸，使得第二处理器能够执行第一存储器PD内的第一处理。 关于第一处理，第一和第二处理器对公共存储器的访问被限制到第一存储器PD，其确保第一和第二处理器彼此的安全性。

Abstract: Systems and techniques are described for establishing one or more virtual sessions between users. For instance, a first device can transmit, to a second device, a call establishment request for a virtual representation call for a virtual session and can receive, from the second device, a call acceptance indicating acceptance of the call establishment request. The first device can transmit, to the second device, first mesh information for a first virtual representation of a first user of the first device and first mesh animation parameters for the first virtual representation. The first device can receive, from the second device, second mesh information for a second virtual representation of a second user of the second device and second mesh animation parameters for the second virtual representation. The first device can generate, based on the second mesh information and the second mesh animation parameters, the second virtual representation of the second user.

Abstract: A method by a wearable device is described. The method includes receiving geometric information from a controller. The geometric information includes a point cloud and a key frame of the controller. The method also includes receiving first six degree of freedom (6DoF) pose information from the controller. The method further includes synchronizing a coordinate system of the wearable device with a coordinate system of the controller based on the point cloud and the key frame of the controller. The method additionally includes rendering content in an application based on the first 6DoF pose information.
