Abstract:

The present embodiments relate to automated memory creation and retrieval from moment content items. In some implementations, the automated memory creation and retrieval system can obtain moment content items from user-designated sources with a single user perspective or multiple user perspectives. The moment content items can be assigned tags and arranged in chronological order. The arranged moment content items can be clustered into memory content items based on clustering conditions. Once memory content items are created, they can be arranged into a memory hierarchy made up of connected nodes. In some implementations, the memory content items are also linked together based on similarity in various dimensions in a memory graph. The automated memory creation and retrieval system can receive search criteria for memories from a user interface and provide the user with memories from matched nodes in the memory hierarchy or linked memories in the memory graph.

Abstract:

Various client devices include displays and one or more image capture devices configured to capture video data. Different users of an online system may authorize client devices to exchange information captured by their respective image capture devices. Additionally, a client device modifies captured video data based on users identified in the video data. For example, the client device changes parameters of the image capture device to more prominently display a user identified in the video data and may further change parameters of the image capture device based on gestures or movement of the user identified in the video data. The client device may apply multiple models to captured video data to modify the captured video data or subsequent capturing of video data by the image capture device.

Abstract:

A conversation augmentation system can automatically augment a conversation with content items based on natural language from the conversation. The conversation augmentation system can select content items to add to the conversation based on determined user “intents” generated using machine learning models. The conversation augmentation system can generate intents for natural language from various sources, such as video chats, audio conversations, textual conversations, virtual reality environments, etc. The conversation augmentation system can identify constraints for mapping the intents to content items or context signals for selecting appropriate content items. In various implementations, the conversation augmentation system can add selected content items to a storyline the conversation describes or can augment a platform in which an unstructured conversation is occurring.

Abstract:

This disclosure describes a computing system that automatically detects users in visual proximity and adds the users to a private collaboration space enabling the users to share digital content. In one example, the computing system includes a video processing engine configured to detect, from first image data representative of a first physical environment that includes a second user, the second user, wherein the first image data is captured by an image capture system of a head-mounted display (HMD) worn by a first user. The computing system also includes a collaboration application configured to add, in response to detection of the second user, the second user to a set of users associated with a private collaboration space in which the set of users access shared digital content, wherein the set of users includes the first user.

International Classification:

Abstract:

Various client devices include displays and one or more image capture devices configured to capture video data. Different users of an online system are associated with client devices that exchange information captured by their respective image capture devices. When exchanging information, presentation of content to users associated with different client device may be initially synchronized across the client devices. To synchronize content presentation, a client device initiating presentation of the content transmits a request identifying the content and an initial time to other client devices. The initial time is greater than than a maximum return time or latency in a network coupling the client devices and the online system from a time when the request is transmitted. A client device determined to be out of synchronization with one or more other client devices receives a command to modify a rate at which the content is presented to reestablish synchronization.
