    Abstract: Some implementations disclosed herein provide systems, methods (200), and devices (10) that use a retinal imaging technique to assess a user's eye (45) accommodation (i.e., focus) during use of an electronic device (10), e.g., in real time. One or more light sources (322a-d, 1022a-d) produce one or more illuminated spots (320, 420, 520, 620) on the retina that are detectable via a sensor (324, 1024). The size and shape of the spot(s) (320, 420, 520, 620) depend upon the eye accommodation/focus and thus are used to identify an accommodation/focus change or measure the eye's accommodation/focus. Eye accommodation may be determined in real time while a user is viewing, interacting with, or otherwise experiencing electronic content via the electronic device.

    Abstract: An electronic device includes a microphone, an array of coherent optical emitters, an array of balanced coherent optical vibration sensors, and a processor. Each balanced coherent optical vibration sensor in the array of balanced coherent optical vibration sensors is paired with a coherent optical emitter in the array of coherent optical emitters. The processor is configured to analyze a set of waveforms acquired by the array of balanced coherent optical vibration sensors; identify, using the analysis of the set of waveforms, a set of one or more voices in a field of view; and adjust an output of the microphone to accentuate a particular voice in the set of one or more voices.

    Abstract: Various implementations disclosed herein include devices, systems, and methods that provide retinal imaging-based gaze tracking In some implementations, a user's gaze is tracked based on a retinal imaging technique that selectively uses a subset of multiple light sources (222, 310, 610) that illuminate different portions of the user's retina (352). In some implementations, a method (700) includes selecting (710) a subset of light sources, where the subset of the light sources includes less than all of the light sources. In some implementations, one or more portions of a retina (352) are illuminated (720) by producing light using the subset of the light sources. In some implementations, sensor data is received (730) at a sensor (224, 340, 814), the sensor data corresponding to the light detected during retinal imaging, and an eye characteristic is determined (740) based on the sensor data.

    Abstract: Various implementations disclosed herein include devices, systems, and methods that provide retinal imaging-based gaze tracking. In some implementations, a user's gaze is tracked based on based on a retinal imaging technique that corrects for misalignment between content display components and tracking components. In some implementations, misalignment is detected by providing a light pattern (e.g., IR light sources embedded in a display) within or adjacent to displayed content and assessing the image of the light pattern on the retina.
