Assigning priority for an automated assistant according to a dynamic user queue and/or multi-modality presence detection

A method implemented by one or more processors, the method comprising:

• processing, at a computing device, a first set of one or more images captured by a camera that is connected to the computing device, wherein the computing device provides access to an automated assistant;
• determining, based on processing the first set of one or images, that a first user is located within a field of view of the camera;
• generating, based on determining that the first user is located within the field of view of the camera, queue data that assigns the first user with a position in a priority queue for the computing device and characterizes a timer that, when initialized, gradually decreases an amount of time remaining for the first user to be assigned their respective position in the priority queue for the computing device;
• processing, at the computing device and subsequent to generating the queue data, a second set of one or more images captured by the camera;
• determining, based on processing the second set of one or more images, that a second user is located within the field of view of the camera;
• causing, based on determining that the second user is located within the field of view of the camera, the queue data to identify the second user as being assigned another position in the priority queue for the computing device,
• wherein the position assigned to the first user is prioritized over the other position assigned to the second user;
• processing, at the computing device and subsequent to generating the queue data, a third set of one or more images captured by the camera;
• determining, based on processing the third set of one or more images captured by the camera, whether the field of view of the camera includes the first user and/or the second user;
• when the field of view of the camera is determined to include the second user but not include the first user:
• causing, based on the field of view of the camera being determined to include the second user but not include the first user:
• the queue data to indicate that the second user is assigned the position in the priority queue for the computing device and the first user is assigned the other position in the priority queue for the computing device, and
• the timer to initialize in order to gradually decrease the amount of time remaining for the first user to be assigned the other position in the priority queue for the computing device.
