Abstract: Head-mountable devices can include a light projection display element that is directly coupled to an assembly that includes a waveguide. Such a direct coupling can be achieved by bonding the light projection display element directly to a lens or other optical component that is, in turn, directly coupled to the waveguide. Such an optical module can be assembled outside of the head-mountable device for precision alignment and subsequently installed as an integrated unit. These measures can help maintain component alignment while allowing a head-mountable device to be lightweight and small in size.

Abstract: Head-mountable devices can include an arrangement of components that include a waveguide that is decoupled from the ability of system loads to be transferred into the waveguide. Such decoupling can be achieved by utilizing an elastic bond with low stiffness to bond certain components together. This allows the system to flex and deform without transferring stress to the waveguide. Such decoupling can also be achieved by selectively bonding in regions that have relatively lower displacements between a support structure and the waveguide. These measures can help preserve component alignment while allowing a head-mountable device to be lightweight and small in size.

Abstract: A display system may include a waveguide with an output coupler that couples image light out of the waveguide and towards an eye box. The output coupler may also transmit world light from real-world objects towards the eye box. A bias lens may pass the world light to the output coupler. An adjustable tint layer having multiple states that involve transmission of different amounts of the world light may be disposed between the bias lens and the output coupler. Different states may impart different colors and/or may impart a gradient transmission characteristic to the world light. The bias lens itself may form the adjustable tint layer. The adjustable tint layer may have a transparent electrode layer that is provided with one or more AC voltages that heat the adjustable tint layer. The adjustable tint layer may be a self-switching electrochromic device that includes a transparent solar cell.

Abstract: A head-mounted device may include near-eye displays and gaze tracking components to track a user's gaze. The head-mounted device may include an optical system, including a waveguide and optional lenses to guide images produced by display modules to an eye box. The gaze tracking components may include infrared emitters that emit infrared light toward the user's eyes and infrared sensors that detect infrared light that has been reflected from the user's eyes. To reduce interference with the gaze tracking components from environmental infrared light, the optical system may include an infrared-reflective coating and an infrared-absorptive coating. The infrared-reflective and infrared-absorptive coatings may be formed on the optional lenses or on other transparent structures in the optical system. Together, the infrared-reflective and infrared-absorptive coatings may reduce an amount of environmental infrared light that reaches the gaze tracking components and reduce a thermal load on internal components within the head-mounted device.

Abstract: An electronic device may include an optical combiner with a waveguide. The waveguide may have an output coupler that directs high resolution light towards an eye box within a field of view. Peripheral light sources may provide low resolution peripheral light to the eye box about a periphery of the field of view. The peripheral light sources may be mounted to a frame for the waveguide, to an additional substrate mounted to the frame and overlapping the waveguide, in a low resolution projector that projects the peripheral light towards reflective structures in the additional substrate, or in a display module that produces the high resolution light. The optical combiner may overlay real world light with the high resolution light and the low resolution peripheral light.

Abstract: A display may include a waveguide having an output coupler that couples image light out of the waveguide and towards a lens, which imparts a first power to the image light. A cover layer may have an outer surface with a three-dimensional curvature and an inner surface. A portion of the inner surface overlapping the output coupler may have a different three-dimensional curvature that forms an additional lens in the cover layer that transmits world light to the output coupler. The output coupler may transmit the world light to the lens, which transmits the world and image light to the eye box. The curvature of the portion of the inner surface may impart power to the world light that reverses the first power and/or a power imparted to the world light by the outer surface of the cover layer.

Abstract: Head-mountable devices can include connection mechanisms that provide adjustable and exchangeable connections with other devices to enhance performance of the head-mountable device. Such connections can provide both mechanical engagement and operable communication between the connected devices. Accessory devices and/or external devices can be easily connected to provide different components and functions at different times as desired. Accordingly, a main portion of the head-mountable device need not include permanent components that provide every function that will later be desired by the user. Instead, the head-mountable device can have expanded and customizable capabilities by the use of one or more accessory devices.

Abstract: A head-mounted device may have a left display and a right display that provide respective left and right images. Left and right optical combiner systems may be configured to pass real-world light to left and right eye boxes while directing the left and right images respectively to the left and right eye boxes. Misalignment of the left and right images with respect to the left and right eye boxes may be detected using gaze tracking systems, using cameras such as front-facing cameras in conjunction with a database of known real-world object properties, using visual inertial odometry systems formed from cameras and inertial measurement units, or using one or more sensors in a portable head-mounted device case or other item with a receptacle configured to receive a head-mounted device. Compensating adjustments may be made to the images based on the measured misalignment.
