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: An electronic device may include a display module that produces light having an image, a lens that directs the light to a waveguide, and a waveguide that directs the light to an eye box. The lens may produce a foveated image in the light by applying a non-uniform magnification to the image in the light. The non-uniform magnification may vary as a function of angle within a field of view of the lens. This may allow the foveated image to have higher resolution within the central region than in the peripheral region. Performing foveation using the lens maximizes the resolution of images at the eye box without increasing the size of the display module. Control circuitry on the device may apply a pre-distortion to the image that is an inverse of distortion introduced by the lens in producing the foveated image.

Abstract: A head-mounted device includes a device housing, a support structure that is connected to the device housing to support the device housing with respect to a user, a display device that is connected to the device housing to display content, an optical system that is associated with the display device, and sensors that generate sensor output signals. The head-mounted device also includes a tension controller that determines a tensioning command based on the sensor output signals, and a tension adjuster that applies tension to the user according to the tensioning command in order to restrain motion of the device housing with respect to the user.

Abstract: A head-mounted device may have displays that provide images. Waveguides may be used in conveying the images to eye boxes. The waveguides may overlap lenses in a glasses frame or other head-mounted support structure. The waveguides and lenses may be transparent. This allows real-world objects to be viewed from the eye boxes. Infrared-light reflectors may overlap the lenses. Gaze tracking system light sources may supply infrared light that reflects from the infrared-light reflectors to the eye boxes to illuminate a user's eyes. Gaze tracking system cameras capture gaze tracking images of the eyes from the eye boxes to track the user's gaze. Fiducials associated with the infrared-light reflectors may be monitored using the gaze tracking system cameras. This allows components such as the gaze tracking system cameras to be calibrated.

Abstract: A head-mounted device may have a head-mounted support structure with a left side portion, a right side portion, and a transparent front portion forming a lens. The lens may extend across the front of a user's face between the left and right side portions. The lens may have a mirror coating or other optical coating that helps obscure objects on the inner side of the lens when viewed from an exterior region surrounding the head-mounted device. Left and right forward-facing cameras with overlapping fields of view may be used to capture visible-light images through the lens. The cameras may also be used for gaze tracking. Left and right light sources may provide eye illumination that reflects from the lens into left and right eye boxes. Images from the eye boxes may reflect from the lens towards the left and right forward-facing cameras.

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-mountable device can provide passive cooling that utilizes surfaces of an optical assembly to allow heat to be managed in a manner that does not detrimentally impact the visual information displayed to the user. Lenses can be coated with a transparent and thermally conductive material, such as silver nanowire. Such a thermal layer can provide superior thermal conductivity, transmittance, flexibility, flat transmission, low cost, and angular color stability. The thermal layer can passively manage heat by increasing the surface area across which heat can be efficiently dissipated.

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.
