Abstract: A system may include electronic devices such as a head-mounted electronic device, a cellular telephone, a wristwatch device, a computer, and other devices. During operation of the system, one or more of the electronic devices may gather information on the positions of the electronic devices. Information may also be gathered on the positions of objects and obstructions. This position information and/or other information such as information on which sensor resources are available in each of the devices may be used to determine which of the sensors of the electronic devices in the room should be shared. Shared sensors may gather information that is communicated wirelessly to other devices for use by those devices.

Abstract: A head-mounted device may have a head-mounted support structure with left and right portions that are coupled at a nose bridge portion. The left and right portions may support respective clear transparent members that form left and right lenses. During operation of the head-mounted device, a user with eyes located in left and right eye boxes may view real-world objects through the left and right lenses. A left display system may have a left display device that faces inwardly and a right display device that faces inwardly. Input couplers, waveguides, and output couplers may be used to supply left and right images from the left and right display systems to the left and right eye boxes. The left display device and right display device may be mounted in the nose bridge portion of the head-mounted support structure.

Abstract: A head-mounted device may have a head-mounted support structure. Gaze tracking systems may be supported by the support structure so that the gaze of a user may be monitored. Lenses may be supported by the support structure. Display systems may provide computer-generated images to the user while the user is viewing real-world objects through the lenses. The gaze tracking systems may include image-sensor-based systems such as glint-based systems. A glint-based gaze tracking system may include light-emitting devices that emit light beams that create eye glints on the surface of a user's eyes and may include an image sensor that measures the eye glints to gather information on the user's gaze. A low-power gaze tracking system may be included in the head-mounted device. The low-power gaze tracking system may use light detectors to measure the magnitudes of respective light reflections of the light beams.

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: 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: 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 head-mounted device may have a transparent display. The transparent display may be formed from a display unit that provides images to a user through an optical coupler. A user may view real-world objects through the optical coupler while control circuitry directs the transparent display to display computer-generated content over selected portions of the real-world objects. The head-mounted display may also include an adjustable opacity system. The adjustable opacity system may include an adjustable opacity layer such as a photochromic layer that overlaps the optical coupler and a light source that selectively exposes the adjustable opacity layer to ultraviolet light to control the opacity of the adjustable opacity layer. The adjustable opacity layer may block or dim light from the real-world objects to allow improved contrast when displaying computer-generated content over the real-world objects.
