    Abstract: An electronic device may include an optical module with a display and a tunable lens. During operation, the electronic device may gather data and adjust the tunable lens based on the gathered data. The optical module may include a non-adjustable lens element with convex curvature in addition to the tunable lens. The optical module may include a Fresnel lens element in addition to the tunable lens. The optical module may include a catadioptric lens in addition to the tunable lens. The optical module may include a catadioptric lens that includes the tunable lens. The optical module may have a birdbath architecture that includes the tunable lens. The optical module may include a waveguide and the tunable lens may be an adjustable positive bias lens and/or an adjustable negative bias lens.

    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 disclosed herein include devices, systems, and methods that dynamically-size zones used in foveated rendering of content that includes text. In some implementations, this involves adjusting the size of a first zone, e.g., a foveated gaze zone (FGZ), based on the apparent size of text from a viewpoint. For example, a FGZ may be increased or decreased in width, height, diameter, or other size attribute based on determining an angle subtended by one or more individual glyphs of the text from the viewpoint. Various implementations disclosed herein include devices, systems, and methods that select a text-rendering algorithm based on a relationship between (a) the rendering resolution of a portion of an image corresponding to a part of a glyph and (b) the size that the part of the glyph will occupy in the image.

    Abstract: Methods and systems for relative inertial measurement may include a user device comprising an inertial measurement device and/or a camera. A second inertial measurement device may be configured to move with a reference frame. One or more processors may receive inertial measurements from the first and second inertial measurement devices and determine movement of the user device relative to the reference frame by comparing the received inertial measurements. Additionally reference objects in a view of a camera may be used to calibrate the determined motion of the user device within the reference frame.
