Abstract: Structured light is projected onto an object, and an image of the object as illuminated by the projected structured light is captured. Reference object points are identified within the captured image, and the structured light projected onto the object is modified based on the identified reference object points. An additional image of the object as illuminated by the modified projected structured light is captured, and additional reference object points are identified within the captured additional image.

Abstract: A computing device receives a notification from a tracking device that the tracking device has entered a gripped state in which a user has securely gripped the tracking device with a hand of the user. The computing device responsively receives orientation data from the tracking device indicative of an orientation of the tracking device in a tracking device space. The computing device determines an orientation of the hand of the user in a hand tracking space from captured image data of the hand of the user and the tracking device. The computing device generates a transformation matrix to anchor the tracking device space to the hand tracking space. The tracking device resultantly enters an anchored state.

Abstract: In various examples, a head-mountable display (“HMD”) may include a light source to emit light across a target region of a wearer, a light sensor, and a circuitry operably coupled with the light source and the light sensor. The circuitry may operate the light source to periodically emit light across the light sensor. Based on a determination that a time interval since the circuitry last received a signal from the light sensor satisfies a threshold, the circuitry may trigger a remedial action to cause the light source to cease emission of light across the target region of the wearer.

Abstract: Facial movement of a wearer of a head-mountable display (HMD) is detected by detecting movement of a gasket of the HMD positioned against a face of the wearer using resistive or magnetic sensors within the gasket. A facial expression of the wearer is identified based on the detected facial movement.

Abstract: In an example in accordance with the present disclosure, an extended reality system is described. The extended reality system includes an imaging system to present virtual objects to a user. The extended reality system also includes a machine vision tracking system. The machine vision tracking system includes a camera to capture images of a user's hand a tool grasped in the user's hand. The machine vision tracking system also includes a processor. The processor 1) tracks a position and orientation of the user's hand in physical space, 2) identifies the tool grasped in the user's hand, and 3) tracks a position and orientation of the tool in physical space. The extended reality system also includes an XR controller to manipulate the XR environment based on the position and orientation of the tool and the position and orientation of the hand.

Abstract: An adaptable connector, a non-standard PCIe module, and a computer readable medium are disclosed. The adaptable connector for a PCIe interface allows for multiple standard PCIe modules and non-standard PCIe modules at different times An external I/O port has a set of non-PCIe I/O signal lanes coupled to the adaptable connector in lieu of a set of root port host PCIe signal lanes when a non-standard PCIe module is mated to the adaptable connector.
