A wearable device may include a head-mounted display (HMD) for rendering a three-dimensional (3D) virtual object which appears to be located in an ambient environment of a user of the display. The relative positions of the HMD and one or more eyes of the user may not be in desired positions to receive image information outputted by the HMD. For example, the HMD-to-eye vertical alignment may be different between the left and right eyes. The wearable device may determine if the HMD is level on the user's head and may then provide the user with a left-eye alignment marker and a right-eye alignment marker. Based on user feedback, the wearable device may determine if there is any left-right vertical misalignment and may take actions to reduce or minimize the effects of any misalignment.

Display systems and methods for determining vertical alignment between left and right displays and a user's eyes

A wearable device includes a left optical stack having a left eyepiece configured to receive left virtual image light, a left accommodating lens, and a left compensating lens. The wearable device also includes a right optical stack having a right eyepiece configured to receive right virtual image light, a right accommodating lens, and a right compensating lens. An optical power of the left accommodating lens is equal in magnitude to an optical power of the left compensating lens, an optical power of the right accommodating lens is equal in magnitude to an optical power of the right compensating lens, and the optical power of the left accommodating lens and the optical power of the right accommodating lens differ by an offset amount.

Monovision display for wearable device

A method of generating foveated rendering using temporal multiplexing includes generating a first spatial profile for an FOV by dividing the FOV into a first foveated zone and a first peripheral zone. The first foveated zone will be rendered at a first pixel resolution, and the first peripheral zone will be rendered at a second pixel resolution lower than the first pixel resolution. The method further includes generating a second spatial profile for the FOV by dividing the FOV into a second foveated zone and a second peripheral zone, the second foveated zone being spatially offset from the first foveated zone. The second foveated zone and the second peripheral zone will be rendered at the first pixel resolution and the second pixel resolution, respectively. The method further includes multiplexing the first spatial profile and the second spatial profile temporally in a sequence of frames.

Methods to improve the perceptual quality of foveated rendered images

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 determining a fixation point of a user's eyes. Location information associated with a first virtual object to be presented to the user via a display device is obtained. A resolution-modifying parameter of the first virtual object is obtained. A particular resolution at which to render the first virtual object is identified based on the location information and the resolution-modifying parameter of the first virtual object. The particular resolution is based on a resolution distribution specifying resolutions for corresponding distances from the fixation point. The first virtual object rendered at the identified resolution is presented to the user via the display system.

Depth based foveated rendering for display systems

A wearable device may include a head-mounted display (HMD) for rendering a three-dimensional (3D) virtual object which appears to be located in an ambient environment of a user of the display. The relative positions of the HMD and one or more eyes of the user may not be in desired positions to receive image information outputted by the HMD. For example, the HAMID-to-eye vertical alignment may be different between the left and right eyes. The wearable device may determine if the HMD is level on the user's head and may then provide the user with a left-eye alignment marker and a right-eye alignment marker. Based on user feedback, the wearable device may determine if there is any left-right vertical misalignment and may take actions to reduce or minimize the effects of any misalignment.

Wearable and optical display systems and methods for operation thereof incorporating monovision display techniques are disclosed. A wearable device may include left and right optical stacks configured to switch between displaying virtual content at a first focal plane or a second focal plane. The wearable device may determine whether or not an activation condition is satisfied. In response to determining that the activation condition is satisfied, a monovision display mode associated with the wearable device may be activated, which may include causing the left optical stack to display the virtual content at the first focal plane and causing the right optical stack to display the virtual content at the second focal plane.

An image display system includes an optical subsystem configured to emit a modulated light beam, and a scanning mirror for generating a reflected light beam that is scanned according to randomly selected or pseudo-randomly selected scan patterns to generate multiple image fields of a multiple interlaced scan image. A plurality of different scan patterns can be cycled through, randomly or pseudo-randomly selected, for the different image fields to reduce artifacts that may be observed while viewing a projected image.

Method and system for reducing line separation artifacts in interlaced image projection

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.
