Abstract: A head-mounted device may have projectors that provide images. Waveguides in lenses may be used in conveying the images to eye boxes. A head-mounted frame in the head-mounted device may have lens openings that receive the lenses. The frame may include a frame member such as an elongated metal member that extends across the frame above the left and right lenses. The frame may include frame structure such as polymer structures that cover the frame member and that are configured to form the lens openings. The frame member may have a cable channel. Cabling may be used to route signals between the projectors, strain gauge circuitry, control circuitry, and other circuits in the head-mounted device. The cabling may be received within the cable channel and encapsulated in a protective polymer. Additional polymer may be molded over the protective polymer to form the frame.

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.
