    Abstract: Various implementations disclosed herein include devices, systems, and methods for detecting and correcting the posture of users of electronic devices. In some implementations, an image capture device or other sensor is used to estimate or otherwise determine a posture of a user. As a specific example, a head mounted device (HMD) may include a camera that captures an image of the user wearing the device and the image may be analyzed to identify 3D joint locations representing the current posture of the user relative to the HMD. The user's posture is analyzed to assess whether a posture correction or change is desirable, for example, by classifying the posture as good or bad or by scoring the posture on a numerical scale. If a posture correction or change is desirable, appropriate feedback to encourage the user to adopt the posture correction or otherwise change his or her posture is identified and provided.

    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: Implementations disclosed herein provide systems and methods that use classification-based machine learning to generate perceptually-plausible content for a missing part (e.g., some or all) of an image. The machine learning model may be trained to generate content for the missing part that appears plausible by learning to generate content that cannot be distinguished from real image content, for example, using adversarial loss-based training. To generate the content, a probabilistic classifier may be used to select color attribute values (e.g., RGB values) for each pixel of the missing part of the image. To do so, a pixel color attribute is segmented into a number of bins (e.g., value ranges) that are used as classes. The classifier determines probabilities for each of the bins of a color attribute for each pixel and generates the content by selecting the bin having the highest probability for each color attribute for each pixel.

    Abstract: In some implementations, a method includes obtaining a computer graphic generated based on one or more visual elements within a first video frame. In some implementations, the first video frame is associated with a first time. In some implementations, the method includes obtaining a second video frame associated with a second time. In some implementations, the second time is different from the first time. In some implementations, the method includes applying an intensity transformation to the computer graphic in order to generate a transformed computer graphic. In some implementations, the intensity transformation is based on an intensity difference between the first video frame and the second video frame. In some implementations, the method includes rendering the transformed computer graphic based on one or more visual elements within the second video frame.

In one implementation, a method includes generating, using an event camera comprising a plurality of light sensors at a plurality of respective locations, a plurality of event messages, each of the plurality of event messages being generated in response to a particular light sensor detecting a change in intensity of light and indicating a particular location of the particular light sensor. The method includes determining an eye tracking characteristic of a user based on the plurality of event messages.
