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: In an example in accordance with the present disclosure, a system is described that includes a hub for routing data traffic between a first computing device and a second computing device. A detection device of the system detects a communication protocol between the computing devices. A switch of the system routes traffic directly between the computing devices when a first communication protocol is detected. When a second communication protocol is detected, the switch re-routes traffic of the first type from the first computing device back to the hub to convert the traffic of the first type to a second type and routes converted traffic directly to the second computing device.

Abstract: Examples of a method for emotive avatar animation are described. Some examples of the method may include combining first user pose data captured by an external camera with second user pose data captured by a head-mounted display (HMD). Some examples of the method may include animating an emotive avatar based on the combined user pose data.

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: 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: 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.
