Abstract: Techniques and systems are provided for capturing images by a first device. For instance, a process can include obtaining a first image from a first camera, the first image being associated with a first capture time based on a first clock; mapping the first capture time to a second clock to obtain a second capture time, the second capture time based on a second clock, and wherein the second clock is based on a network time; associating the second capture time with the first image; obtaining a second image from a second camera of another device, the second image including a third capture time based on the second clock; determining phase delta information based on a time difference between the second capture time and the third capture time; and outputting the phase delta information to adjust a next capture time of at least one of the first or second camera.

Abstract: Systems and techniques are described herein for using head mounted display (HMD) hinge motion to calibrate the head mounted device. For example, an device (or component of the device) can obtain, via one or more sensors, sensor measurements during rotation of a display of the HMD between a first end of a range of motion of a hinge of the display about an axis and a second end of the range of motion of the hinge about the axis; determine parameters of the HMD based on the sensor measurements and the rotation of the display between the first end of the range of motion of the hinge and the second end of the range of motion of the hinge about the axis; and determine pose information for the HMD based on the determined parameters.

Abstract: Systems and techniques are described for establishing one or more virtual sessions between users. For instance, a first device can transmit, to a second device, a call establishment request for a virtual representation call for a virtual session and can receive, from the second device, a call acceptance indicating acceptance of the call establishment request. The first device can transmit, to the second device, first mesh information for a first virtual representation of a first user of the first device and first mesh animation parameters for the first virtual representation. The first device can receive, from the second device, second mesh information for a second virtual representation of a second user of the second device and second mesh animation parameters for the second virtual representation. The first device can generate, based on the second mesh information and the second mesh animation parameters, the second virtual representation of the second user.

Abstract: Imaging systems and techniques are described. An imaging system receives, from an image sensor, image(s) of a user (e.g., in a pose and/or with a facial expression). The image sensor captures the first set of image(s) in a first electromagnetic (EM) frequency domain, such as the infrared and/or near-infrared domain. The imaging system generates a representation of the user in the first pose in a second EM frequency domain (e.g., visible light domain) at least in part by inputting the image(s) into one or more trained machine learning models. The representation of the user is based on an image property associated with image data of at least the part of the user in the second EM frequency domain. The imaging system outputs the representation of the user in the pose in the second EM frequency domain.
