A messaging system for audio character type swapping. Methods of audio character type swapping include receiving input audio data having a first characteristic and transforming the input audio data to an input image where the input image represents the frequencies and intensities of the audio. The methods further include processing the input image using a convolutional neural network (CNN) to generate an output image and transforming the output image to output audio data, the output audio data having a second characteristic. The input audio and output audio may include vocals. The first characteristics may indicate a male voice and the second characteristics may indicate a female voice. The CNN is trained together with another CNN that changes input audio having the second characteristic to audio having the first characteristic. The CNNs are trained using discriminator CNNs that determine whether audio has a first characteristic or a second characteristic.

Methods, devices, media, and other embodiments are described for managing and configuring a pseudorandom animation system and associated computer animation models. One embodiment involves generating image modification data with a computer animation model configured to modify frames of a video image to insert and animate the computer animation model within the frames of the video image, where the computer animation model of the image modification data comprises one or more control points. Motion patterns and speed harmonics are automatically associated with the control points, and motion states are generated based on the associated motions and harmonics. A probability value is then assigned to each motion state. The motion state probabilities can then be used when generating a pseudorandom animation.

A finger gesture recognition system is provided. The finger gesture recognition system includes one or more audio sensors and one or more optic sensors. The finger gesture recognition system captures, using the one or more audio sensors, audio signal data of a finger gesture being made by a user, and captures, using the one or more optic sensors, optic signal data of the finger gesture. The finger gesture recognition system recognizes the finger gesture based on the audio signal data and the optic signal data and communicates finger gesture data of the recognized finger gesture to an Augmented Reality/Combined Reality/Virtual Reality (XR) application.

A device that measures a size of a user's face, referred to as face scaling, using a monocular camera. Depth is calculated from sparse feature points. A face mesh is used to improve the estimation accuracy. A processing pipeline detects face features by applying a face landmark detection algorithm to find the important face feature points such as the eyes, nose, and mouth. The processing pipeline estimates feature points depth using depth obtained through image defocus. The processing pipeline further scales the face using an estimated depth of the face features.

A pose tracking system is provided. The pose tracking system includes an EMF tracking system having a user-worn head-mounted EMF source and one or more user-worn EMF tracking sensors attached to the wrists of the user. The EMF source is associated with a VIO tracking system such as AR glasses or the like. The pose tracking system determines a pose of the user's head and a ground plane using the VIO tracking system and a pose of the user's hands using the EMF tracking system to determine a full-body pose for the user. Metal interference with the EMF tracking system is minimized using an IMU mounted with the EMF tracking sensors. Long term drift in the IMU and the VIO tracking system are minimized using the EMF tracking system.

Methods, devices, media, and other embodiments are described for generating, modifying, and outputting pseudorandom animations that can be synchronized to audio data. In one embodiment, a computer animation model made up of comprising one or more control points is accessed by one or more processors, which associate motion patterns with a first control point of the one or more control points, and associate one or more speed harmonics with the first control point. A set of motion states is identify with a motion state for the combinations of possibilities, and a probability value is assigned to each motion state of the set of motion states. The probability value can be used to probabilistically determine a particular motion state to be part of displayed animation for the computer animation model.

An audio response system can generate multimodal messages that can be dynamically updated on viewer's client device based on a type of audio response detected. The audio responses can include keywords or continuum-based signal (e.g., levels of wind noise). A machine learning scheme can be trained to output classification data from the audio response data for content selection and dynamic display updates.

Method to retrieve media content items using captured parameters associated with a moment starts with a processor detecting an activation of a selectable element. Processor determines parameters associated with the activation including a date and a time that the activation is detected and a location of the selectable element when the activation is detected. Processor stores in a memory of a client device a first record including the parameters. When a request for the first record is received, processor transmits the request to a server for media content items associated with at least one of the parameters of the first record. Media content items are uploaded to the server from client devices communicatively coupled to the server. Processor causes a display of the client device to display the media content items. Other embodiments are described herein.
