Abstract: In one embodiment, a method includes rendering a first output image comprising one or more augmented-reality (AR) objects for displays of an AR rendering device of an AR system associated with a first user. The method further includes accessing sensor signals associated with the first user. The one or more sensor signals may be captured by sensors of the AR system. The method further includes detecting a change in a context of the first user with respect to a real-world environment based on the sensor signals. The method further includes rendering a second output image comprising the AR objects for the displays of the AR rendering device. One or more of the AR objects may be adapted based on the detected change in the context of the first user.

Abstract: In one embodiment, a method includes receiving a media content for delivery to a first user, wherein the media content is associated with a priority level, accessing context information associated with the first user, wherein the context information is determined based on one or more multimodal signals from a client device associated with the first user, determining a delivery level for the media content based on the priority level of the media content and the context information, and instructing the client device to present a notification associated with the media content to the first user, wherein the notification is rendered in one or more modalities determined based on the delivery level for the media content.

Abstract: In one embodiment, a method includes presenting a text message comprising n-grams via a user interface of a client system based on a user utterance received at the client system, receiving a first user request at the client system to edit the text message, presenting the text message visually divided into blocks via the user interface, wherein each block comprises one or more of the n-grams of the text message and the n-grams in each block are contiguous with respect to each other and grouped within the block based on an analysis of the text message by a natural-language understanding (NLU) module, receiving a second user request at the client system to edit one or more of the blocks, and presenting an edited text message generated based on the second user request via the user interface.

Abstract: Techniques for determining an answer that relates to a user question when a system is unable to determine an exact answer to the user question are described. When the system receives a user question, the system may parse the user question to determine the words making up the question. The system may then process the words against an indexed dictionary of words to piece the words of the question together to from interpretations of the different possible relationships that may exist between the words. The system may attempt to determine an exact answer to the user question using the indexed words. If the system determines an exact answer, the system may output the answer to the querying user. If the system is unable to determine an exact answer, the system may navigate through a ontology of relationships within a knowledge base to determine an answer that is related to the user question but that may not directly answer the user question.
