causing presentation of a camera interface, the camera interface displaying a first image captured by a camera of a computing device of a first user of an interaction system;

identifying a set of users of the interaction system that are associated with the first user;

determining a subset of the set of users that have been active on the interaction system within a determinable time period;

causing presentation, within the camera interface, of a rotatable carousel interface which includes a graphical element for each user of the subset of users, each graphical element being user-selectable to invoke an augmentation mechanism, the rotatable carousel interface being configured to receive a swipe gesture for rotating through the graphical elements;

detecting user selection of a first graphical element associated with a second user of the subset; and

causing presentation, within the camera interface and responsive to the detection of the user selection of the first graphical element, of an augmentation of the first image to generate an augmented image

wherein the augmentation comprises one or more second images of an avatar representation of the second user, and a third image comprising a clock indicating a time of a most recent activity by the second user, and

wherein causing presentation of the augmentation comprises combining the first image, the second image and the third image to create the augmented image, such that the first image, the second image and the third image are simultaneously displayed in response to the detection of the user selection of the first graphical element.
