Abstract: Methods and apparatus for measuring biometric data including temperature in head-mounted devices (HMDs). Thermal sensors may also be integrated into the HMD and used to collect thermal data from the surface of the user's face. This thermal data may, for example, be processed to determine core body temperature of the user, or be processed to generate estimates of the user's respiration. The temperature data and/or respiration rate and changes to respiration rate derived from signals from the sensors may be used to generate and present biometric data to the user.

Abstract: A head-mounted device may include a housing having openings that receive lenses. Displays may output images. Waveguides that overlap the lenses may receive the images from the displays and may direct the images to eye boxes that are aligned with the lenses. Infrared light sources such as infrared light-emitting diodes or lasers may be used to supply infrared light to the waveguides. Each waveguide may have multiple localized output couplers that overlap the lenses. The localized output couplers of each lens each direct a beam of the infrared light out of the waveguide towards an eye surface in the eye box associated with that lens to produce an eye glint. A gaze tracker infrared camera may captured images of the eye glints to determine a user's point of gaze.

Abstract: A head-mounted device may include a first display having a first projector and a first waveguide, a second display having a second projector and a second waveguide, first and second cameras, an optical sensor that couples the first waveguide to the second waveguide, and position sensors mounted to the first and second cameras and the optical sensor. The optical sensor may gather image sensor data from first image light propagating in the first waveguide and second image light propagating in the second waveguide. The cameras may capture real-world images. The position sensors may gather position measurements. Control circuitry may calibrate optical misalignment in the device by adjusting the first and/or second image light based on the image sensor data, the position measurements, and/or the world light.

Abstract: Eyewear such as a head-mounted device may include display-optimized lenses. The lenses may be optimized for viewing an external display while also providing sun protection for the user's eyes. The external display may form part of a handheld electronic device that serves as a controller for the head-mounted device. The lenses in the head-mounted device may reduce ambient light brightness while maintaining the brightness of the external display so that the user can use the external display while wearing the head-mounted device. The user may, for example, provide touch input to the external display to adjust display content on the head-mounted display. The lenses may include a polarizer and a color filter having a transmission spectrum curve with peaks corresponding to the primary colors of the external display. The lenses may be removable clip-on lenses and the light filter may be an electrochromic filter.
