    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-mountable electronic device can include a frame, a first display window attached to the frame, a second display window attached to the frame, a first waveguide associated with the first display window, a second waveguide associated with the second display window, a first arm connected to the frame, the first arm including a first projector to emit light into the first waveguide, the first projector pivotable relative to the first waveguide, and a second arm connected to the frame, the second arm including a second projector to emit light into the second waveguide, the second projector pivotable relative to the second waveguide.

    Abstract: A head-mounted device may have a housing with a frame that supports lenses. Each lens may have a positive bias lens element and a negative bias lens element. A waveguide may overlap the lens. During operation, images from the waveguide may be provided to an eye box through the negative bias lens element. An eye sensor such as a gaze tracking camera may operate through the negative bias lens element. The negative bias lens element may have a protruding portion through which the sensor operates, may have a surface facing the sensor that has a curved surface to provide a desired lens characteristic, may have a prism for helping to couple light from the eye box to the eye sensor, and/or may have other features to facilitate use of the eye sensor to monitor the eye of a user in the eye box.

    Abstract: A system can include head-mounted devices that collaborate to process views from cameras of the respective head-mounted devices and identify objects from different perspectives and/or objects that are within the view of only one of the head-mounted devices. Sharing sensory input between multiple head-mounted devices can complement and enhance individual units by interpreting and reconstructing objects, surfaces, and/or an external environment with perceptive data from multiple angles and positions, which also reduces occlusions and inaccuracies. As more detailed information is available at a specific moment in time, the speed and accuracy of object recognition, hand and body tracking, surface mapping, and/or digital reconstruction can be improved. Such collaboration can provide more effective and efficient mapping of space, surfaces, objects, gestures and users.

    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.

    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.
