Claim 15:
16. A method performed at least in part by an autonomous mobile device (AMD), the method comprising:
determining a first proximity value associated with a first user, wherein the first proximity value is indicative of correspondence between a first location in a physical space of the first user and a first predicted location in the physical space of the first user at a first time;
determining the first proximity value exceeds a first threshold value;
determining a first feature vector associated with a first image of a first person;
determining a first similarity value, wherein the first similarity value is indicative of similarity between the first feature vector and a previously stored second feature vector that is associated with the first user;
determining that the first similarity value exceeds a second threshold value; and
generating identification data indicative of the first person being the first user.
