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 more images, that a first user is located within a field of view of the camera and is facing a display interface of the computing device; causing, based on determining that the first user is facing the display interface of the computing device, the display interface to render first personalized content that is based on first content data associated with the first user; 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, wherein the priority queue controls output from at least one hardware element of 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 and that the first user is no longer facing the display interface of the computing device; causing, based on determining that the second user is located within the field of view of the camera of the computing device: the queue data to indicate that the second user is assigned another position in the priority queue for the computing device and the first user is assigned a priority position in the priority queue for the computing device; and prefetching and/or pre-compiling second personalized content that is based on second content data associated with the second user; causing, based on determining that the first user is no longer facing the display interface of the computing device: the timer to initialize in order to gradually decrease the amount of time remaining for the first user to be assigned the priority position in the priority queue for the computing device; causing, responsive to the timer expiring, the second user to be assigned the priority position in the priority queue for the computing device; and causing, responsive to the second user being assigned the priority position in the priority queue for the computing device, the display interface to render the second personalized content. 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;
