    Abstract: Head-mountable devices can include adjustment mechanisms to achieve optimal alignment of optical components during and/or after assembly thereof within the head-mountable device. The alignment mechanisms can be integrated into the head-mountable device itself. A light projecting display element can be adjustable based on movement of ramp members within the head-mountable device (e.g., within an arm) to adjust an orientation of the light projecting display element relative to the waveguide onto which it projects light. Alignment can be verified based on the optical output of the display element. The adjustment mechanisms can adjust the display element during initial assembly and/or be operated by actuators that actively adjust the alignment as needed over time.

    Abstract: Head-mountable devices can include adjustment mechanisms to achieve optimal alignment of optical components during and/or after assembly thereof within the head-mountable device. The alignment mechanisms can be integrated into the head-mountable device itself. A light projecting display element can be adjustable based on operation of one or more actuators within the head-mountable device (e.g., within an arm) to adjust a position and/or orientation of the light projecting display element relative to the waveguide onto which it projects light. The adjustment mechanisms can adjust the display element during initial assembly and/or be operated by actuators that actively adjust the alignment as needed over time.

    Abstract: An electronic device such as a head mounted device may have a head-mounted support structure. A portion of the head-mounted support structure may form a transparent housing member through which real-world objects can be viewed from eye boxes. A display system for the head-mounted device may have a display device that provides image light to a waveguide and may have an output coupler that couples the image light out of the waveguide toward the eye box. Peripheral portions of the transparent housing member or other peripheral device structures may be provided with a peripheral display that emits diffuse light into a user's peripheral vision. The peripheral display may use light guide structures, light sources, reflective structures, and other structures that provide transparency to real-world light.

    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.
