Abstract: A display system can include a head-mounted display configured to project light to an eye of a user to display virtual image content at different amounts of divergence and collimation. The display system can include an inward-facing imaging system images the user's eye and processing electronics that are in communication with the inward-facing imaging system and that are configured to obtain an estimate of a center of rotation of the user's eye. The display system may render virtual image content with a render camera positioned at the determined position of the center of rotation of said eye.

Abstract: A display system includes a head-mounted display configured to project light, having different amounts of wavefront divergence, to an eye of a user to display virtual image content appearing to be disposed at different depth planes. The wavefront divergence may be changed in discrete steps, with the change in steps being triggered based upon whether the user is fixating on a particular depth plane. The display system may be calibrated for switching depth planes for a main user. Upon determining that a guest user is utilizing the system, rather than undergoing a full calibration, the display system may be configured to switch depth planes based on a rough determination of the virtual content that the user is looking at. The virtual content may have an associated depth plane and the display system may be configured to switch to the depth plane of that virtual content.

Abstract: Disclosed here in are systems and methods for mapping environment information. In some embodiments, the systems and methods are configured for mapping information in a mixed reality environment. In some embodiments, the system is configured to perform a method including scanning an environment including capturing, with a sensor, a plurality of points of the environment; tracking a plane of the environment; updating observations associated with the environment by inserting a keyframe into the observations; determining whether the plane is coplanar with a second plane of the environment; in accordance with a determination that the plane is coplanar with the second plane, performing planar bundle adjustment on the observations associated with the environment; and in accordance with a determination that the plane is not coplanar with the second plane, performing planar bundle adjustment on a portion of the observations associated with the environment.
