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: 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 method is disclosed, the method comprising the steps of receiving, at a first time interval from a first sensor configured to output data indicative of a first position of an eye, first data; receiving, at a second time interval from a second sensor configured to output data indicative of a delta position of the eye, second data; determining, based on the first data, a first position of the eye; determining, based on the second data, a delta position of the eye; determining, using the first position of the eye and the delta position of the eye, a second absolute position of the eye; and in response to determining the second position of the eye, generating an output signal indicative of the second position of the eye.
