Abstract: Methods and systems for depth-based foveated rendering in the display system are disclosed. The display system may be an augmented reality display system configured to provide virtual content on a plurality of depth planes using different wavefront divergence. Some embodiments include monitoring eye orientations of a user of a display system based on detected sensor information. A fixation point is determined based on the eye orientations, the fixation point representing a three-dimensional location with respect to a field of view. Location information of virtual objects to present is obtained, with the location information indicating three-dimensional positions of the virtual objects. Resolutions of at least one virtual object is adjusted based on a proximity of the at least one virtual object to the fixation point. The virtual objects are presented to a user by display system with the at least one virtual object being rendered according to the adjusted resolution.

Abstract: A head mounted display system can include a camera, at least one waveguide, at least one coupling optical element that is configured such that light is coupled into said waveguide and guided therein, and at least one out-coupling element. The at least one out-coupling element can be configured to couple light that is guided within said waveguide out of said waveguide and direct said light to said camera. The at least one coupling element may comprise a diffractive optical element having optical power. Additionally or alternatively, the at least one coupling optical element may have a coupling area for coupling light into said waveguide having an average thickness in a range from 0.1 to 3 millimeters across and/or may have a slit shaped coupling area.

Abstract: Examples of wearable systems and methods can use multiple inputs (e.g., gesture, head pose, eye gaze, voice, and/or environmental factors (e.g., location)) to determine a command that should be executed and objects in the three-dimensional (3D) environment that should be operated on. The multiple inputs can also be used by the wearable system to permit a user to interact with text, such as, e.g., composing, selecting, or editing text.

Abstract: Systems and methods are disclosed for operating a head-mounted display system based on user perceptibility. The display system may be an augmented reality display system configured to provide virtual content on a plurality of depth planes by presenting the content with different amounts of wavefront divergence. Some embodiments include obtaining an image captured by an imaging device of the display system. Whether a threshold measure or more of motion blur is determined to be exhibited in one or more regions of the image. Based on a determination that the threshold measure or more of motion blur is exhibited in one or more regions of the image, one or more operating parameters of the wearable display are adjusted. Example operating parameter adjustments comprise adjusting the depth plane on which content is presented (e.g., by switching from a first depth plane to a second depth plane), adjusting a rendering quality, and adjusting power characteristics of the system.
