Abstract: A virtual or augmented reality display system can include a first sensor to provide measurements of a user's head pose over time and a processor to estimate the user's head pose based on at least one head pose measurement and based on at least one calculated predicted head pose. The processor can combine the head pose measurement and the predicted head pose using one or more gain factors. The one or more gain factors may vary based upon the user's head pose position within a physiological range of movement.

Abstract: A virtual, augmented, or mixed reality display system includes a display configured to display virtual, augmented, or mixed reality image data, the display including one or more optical components which introduce optical distortions or aberrations to the image data. The system also includes a display controller configured to provide the image data to the display. The display controller includes memory for storing optical distortion correction information, and one or more processing elements to at least partially correct the image data for the optical distortions or aberrations using the optical distortion correction information.

Abstract: A head mounted display system can process images by assessing relative motion between the head mounted display and one or more features in a user's environment. The assessment of relative motion can include determining whether the head mounted display has moved, is moving and/or is expected to move with respect to one or more features in the environment. Additionally or alternatively, the assessment can include determining whether one or more features in the environment have moved, are moving and/or are expected to move relative to the head mounted display. The image processing can further include determining one or more virtual image content locations in the environment that correspond to a location where renderable virtual image content appears to a user when the location appears in the display and comparing the one or more virtual image content locations in the environment with a viewing zone.

Abstract: A virtual or augmented reality display system that controls a display using control information included with the virtual or augmented reality imagery that is intended to be shown on the display. The control information can be used to specify one of multiple possible display depth planes. The control information can also specify pixel shifts within a given depth plane or between depth planes. The system can also enhance head pose measurements from a sensor by using gain factors which vary based upon the user's head pose position within a physiological range of movement.
Abstract translation: 虚拟或增强现实显示系统，其使用旨在显示在显示器上的虚拟或增强现实图像中包含的控制信息来控制显示。 控制信息可用于指定多个可能的显示深度平面中的一个。 控制信息还可以指定给定深度平面内或深度平面之间的像素漂移。 该系统还可以通过使用基于在生理运动范围内的用户头部姿势位置而变化的增益因子来增强来自传感器的头部姿势测量。
