Abstract: Foldable displays may have portions folded into a folded configuration. Each folded portion may be observed by a user at a different viewing angle. As such, folding-artifacts may appear in the displayed image as a result of the different viewing angles. For example, a perceptible color difference and/or a perceptible brightness difference may appear between folded portions. Disclosed here are systems and methods to create compensated images that when displayed reduced the folding artifacts. The creation may include sensing a viewing angle for each portion and determining adjustments for pixels in each portion using a display model. The display model may be created by measuring color and brightness of pixels for various folded configurations, view-points and/or viewing angles.

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.
