Abstract: Implementations relate to an automated assistant that provides and manages output from one or more elements of output hardware of a computing device. The automated assistant manages dynamic adjustment of access permissions to the computing device according to, for example, a detected presence of one or more users. An active-user queue can be established each time a unique user enters a viewing window of a camera of the computing device when, up to that point, no user was considered active. Multiple image frames can be captured via the camera and processed to determine whether an initial user remains in the viewing window and/or whether another user has entered the viewing window. The initial user can be considered active as long as they are exclusively detected in the viewing window. Restricted content associated with the user may be rendered by the computing device whilst the user is active.

Abstract: Techniques are described herein for reducing false positives in vision sensor-equipped assistant devices. In various implementations, initial image frame(s) may be obtained from vision sensor(s) of an assistant device and analyzed to classify a particular region of the initial image frames as being likely to contain visual noise. Subsequent image frame(s) obtained from the vision sensor(s) may then be analyzed to detect actionable user-provided visual cue(s), in a manner that reduces or eliminates false positives. In some implementations, no analysis may be performed on the particular region of the subsequent image frame(s). Additionally or alternatively, in some implementations, a first candidate visual cue detected within the particular region may be weighted less heavily than a second candidate visual cue detected elsewhere in the one or more subsequent image frames. An automated assistant may then take responsive action based on the detected actionable visual cue(s).

Abstract: A method for proactive notifications in a voice interface device includes: receiving a first user voice request for an action with an future performance time; assigning the first user voice request to a voice assistant service for performance; subsequent to the receiving, receiving a second user voice request and in response to the second user voice request initiating a conversation with the user; and during the conversation: receiving a notification from the voice assistant service of performance of the action; triggering a first audible announcement to the user to indicate a transition from the conversation and interrupting the conversation; triggering a second audible announcement to the user to indicate performance of the action; and triggering a third audible announcement to the user to indicate a transition back to the conversation and rejoining the conversation.

Abstract: Techniques are described herein for dialog-based enrollment of individual users for single- and/or multi-modal recognition by an automated assistant, as well as determining how to respond to a particular user's request based on the particular user being enrolled and/or recognized. Rather than requiring operation of a graphical user interface for individual enrollment, dialog-based enrollment enables users to enroll themselves (or others) by way of a human-to-computer dialog with the automated assistant.
