Abstract: A computer implemented method for warping multi-field color virtual content for sequential projection includes obtaining first and second color fields having different first and second colors. The method also includes determining a first time for projection of a warped first color field. The method further includes determining a second time for projection of a warped second color field. Moreover, the method includes predicting a first pose at the first time and predicting a second pose at the second time. In addition, the method includes generating the warped first color field by warping the first color field based on the first pose. The method also includes generating the warped second color field by warping the second color field based on the second pose.

Abstract: A projector assembly includes a light emitting diode (LED) array, wherein the LED array has an array axis, wherein the LED array includes a plurality of LEDs arranged along the array axis, and wherein the plurality of LEDs are individually addressable. The projector assembly includes a rotatable actuator supporting the LED array, wherein the rotatable actuator has a rotation axis, and wherein the rotation axis and the array axis are parallel. The projector assembly includes a collimator positioned in optical communication with the LED array for collimating light emitted from the plurality of LEDs and a set of imaging optics positioned in optical communication with the collimator for focusing collimated light and forming a first image of the LED array at a distance, wherein the first image includes a first axis corresponding to the array axis and a second axis orthogonal to the rotation axis.

Abstract: An eyepiece for a head-mounted display includes one or more first waveguides arranged to receive light from a spatial light modulator at a first edge, guide at least some of the received light to a second edge opposite the first edge, and extract at least some of the light through a face of the one or more first waveguides between the first and second edges. The eyepiece also includes a second waveguide positioned to receive light exiting the one or more first waveguides at the second edge and guide the received light to one or more light absorbers.

Abstract: A thin transparent layer can be integrated in a head mounted display device and disposed in front of the eye of a wearer. The thin transparent layer may be configured to output light such that light is directed onto the eye to create reflections therefrom that can be used, for example, for glint based tracking. The thin transparent layer can be configured to reduced obstructions in the field of the view of the user.
