1. A computer-implemented method comprising: as implemented by a user computing device comprising one or more hardware processors and configured with specific computer-executable instructions, obtaining a continuous stream of images that depict at least a plurality of items located within a physical area, wherein the continuous stream of images are obtained from an image capturing device configured to capture the continuous stream of images; identifying the plurality of items depicted in the continuous stream of images; generating an interactive user interface element comprising a representation of the plurality of items that differs from a presentation of the plurality of items within the continuous stream of images and differs from a presentation of the plurality of items within the physical area; outputting for display to a user the continuous stream of images and the interactive user interface element; receiving, in response to interaction by a user with a portion of the interactive user interface element, a selection of a representation of an item from the plurality of items included in the representation of the plurality of items; and for at least a subset of images of the continuous stream of images output for display, animating at least a portion of each of the subset of images, the portion including a depiction of an item corresponding to the representation of the item selected from the interactive user interface element.
