Abstract: Systems and methods in the present disclosure relate to surface-based user input for extended reality (XR) devices. An XR device tracks a hand of a user across multiple captured image frames to obtain positions of the hand in a real-world environment. The XR device detects an input plane associated with a physical surface in the real-world environment and projects the positions onto the input plane. The XR device continuously monitors an input state with respect to the input plane to identify when the user is providing user input via the input plane and to differentiate between ongoing user input and finalized user input. Based on the monitoring of the input state, the XR device records one or more of the projected positions as input data. The input data is processed to interpret the user input. The XR device executes an action based on the interpreted user input.

The communication method includes: An application server (AS) sends a data stream, where the data stream includes at least two substreams, a first substream in the at least two substreams carries a first substream identifier, the at least two substreams correspond to a same 5-tuple, and substreams in the at least two substreams correspond to different substream identifiers. A user plane function (UPF) receives the data stream, and obtains the first substream identifier of the first substream from the at least two substreams included in the data stream; and maps the first substream to a first quality of service (QoS) flow indicated by a first QoS flow identifier (QFI) corresponding to the first substream identifier. According to the method, substreams in data streams corresponding to different QoS requirements can be mapped to different QoS flows by using substream identifiers of the substreams.

Abstract: Systems and methods in the present disclosure relate to the sharing of hand tracking data in the context of multi-user extended reality (XR) experiences. A first XR device of a first user and a second XR device of a second user participate in a shared XR experience.

The first XR device captures images that include a first hand of the first user and the second hand of the second user. While the shared XR experience is in progress, tracking operations performed by the first XR device are controlled based on the images captured by the first XR device and the hand tracking data it receives from the second XR device.

Abstract: An augmented reality (AR) device generates hand annotations for an image depicting a user's hand. The device includes a display, a processor, and a memory storing instructions for performing operations. The device performs a calibration operation to generate a 3-D model of the user's hand based on measurements. The calibration operation prompts the user to mimic the hand gesture presented by the animated virtual representation of a hand to obtain optimal images of the hand for hand pose estimation. A 3-D virtual representation of a hand in a hand pose corresponding with a hand gesture is generated based on the 3-D model. The device presents the 3-D virtual representation of the hand in AR via the display. During presentation, the device detects an input and captures an image of the user's hand positioned to correspond with the 3-D virtual representation. The captured image is stored with corresponding hand annotations based on the 3-D model.

Abstract: Software applications often incorporate an embedded browser to perform web-based operations. Not all browsers operate the same way, for example, elements within tabs in Microsoft Edge browsers use messages to communicate through web extensions, while Microsoft Internet Explorer (IE) browsers use the original browsers helper object (BHO). A consequence of the different paradigms is that certain graphical elements may be duplicated in a resource table. A test development may fail to identify the duplication and may produce extraneous or erroneous tests. By launching on a system and monitoring the system's executing processes, a browser application may be determined to be running and, if so, a refresh operation is performed on an application under test (AUT). If the AUT refresh operation results in a browser also performing a refresh, the type of embedded browser may be identified and any duplicates of the same graphical elements identified and merged for subsequent testing.

Abstract: A head-worn device system equipped with cameras, display devices, and processors uses stored instructions to facilitate interactions between an augmented reality (AR) device and an external display system. When executed, these instructions establish a communications link between the AR device and the external display. The system identifies the pose of the external display and receives user inputs from the AR device user, relating to interactions with virtual objects in a real-world setting. It also identifies the positions of viewers watching the external display. Based on the external display's pose and the viewer locations, the system generates display data for the virtual object, ensuring it appears correctly on the external display. This display data is then transmitted to the external display system, completing the interaction loop and enhancing the viewing experience for the audience.
