Abstract: Fiducial patterns that produce diffraction patterns at a camera sensor are etched or otherwise provided on the surface of a cover glass (CG) in front of a camera. An active light source injects light into the cover glass or into a diffractive optical element to strengthen the signal from the fiducial pattern, or alternatively an active light source is used to reflect light off a reflective fiducial pattern on the cover glass, thus requiring fewer frames to capture and process the diffraction pattern caused by the fiducial pattern.

Abstract: Methods and apparatus for measuring biometric data including respiration in head-mounted devices (HMDs). Accelerometers may be integrated into a HMD and used to collect motion data from a user's face. This motion data may be processed to generate estimates of the user's respiration rate and changes to the respiration rate. Thermal sensors may also be integrated into the HMD and used to collect thermal data from the surface of the user's face (or other regions of the user's head). This thermal data may also be processed to generate estimates of the user's respiration. The 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: Various implementations disclosed herein include devices, systems, and methods that use a marking on a transparent surface (e.g., a prescription lens insert for an HMD) to identify information (e.g., prescription parameters) about the transparent surface. In some implementations, the markings do not interfere with eye tracking through the transparent surface or using the transparent surface to view virtual content or a physical environment. In some implementations, image data is obtained from an image sensor of an electronic device, the image data corresponding to a transparent surface attached to the electronic device. Then, a code is identified in the image data, wherein the code is detectable on the transparent surface by the image sensor without interfering with a function of the electronic device involving the transparent surface. In some implementations, content is provided at the electronic device based on the identified code, wherein the content is viewable through the transparent surface.

Abstract: Object detection may include transmitting, by a first device, a first pulse into an environment using a wide field configuration of an ultrasonic sensor array, detecting a presence of an object in the environment based on a detected echo based on the first pulse. In response to detecting the presence of the object, a targeted configuration of the ultrasonic sensor array is determined, and a second pulse is transmitted into the environment based on the second pulse, wherein a characteristic of the object is determined based on a detected echo from the second pulse.

Abstract: Various implementations track an eye using both camera images and light sensor data, e.g., from a photosensitive surface or set of photodetectors. The camera need not capture images at a high capture rate since the light sensor data captured from the light sensor provides information about the eye during the time periods between camera frames. An eye tracking device may thus provide eye tracking with high temporal resolution using less power and resources and prior devices. The eye tracking device includes a lens (e.g., a diffractive optical element (DOE)) that splits received light onto the camera and light sensor. The camera and light sensor may be aligned, e.g., co-centered. Using such a lens to provide light to an aligned camera and light sensor facilitates tracking the eye characteristics by reducing the need for matching the data and/or accounting for multiple environmental light sources.
