Abstract: A wrist-pose isolation system can infer a wrist pose (e.g., the user's hand position relative to her forearm) and can reduce wrist-induced jitter for projection casting in an XR environment. A user's projection cast can be determined as a combination of a “low-wrist contribution” component (e.g., a body-and-arm component) and a “high-wrist contribution” component (e.g., the pose of the wrist with respect to the arm). Using input from a gesture-tracking system, the contribution of the user's wrist pose to the user's current projection cast is calculated as a “wrist-contribution vector.” A projection cast direction can be determined as the interpolation of the current low-wrist contribution component and the high-wrist contribution component. This interpolation can be performed by weighting each by a specified amount and combining them.

Abstract: The disclosed computer-implemented method may include generating a virtual item within a virtual environment. The method may also include detecting, using various hardware sensors, a current position of a physical object that is to be portrayed within the virtual environment. The method may next include generating a virtual representation of the physical object within the virtual environment. The virtual representation of the physical object may be configured to at least partially follow movements of the physical object relative to the virtual item. The method may also include presenting the virtual item and the generated virtual representation of the physical object within the virtual environment, where the virtual representation of the physical object is at least partially, controllably decoupled from the movements of the physical object relative to the virtual item. Various other methods, systems, and computer-readable media are also disclosed.
