Abstract: In an approach to generating playlists/sequences of images, a system includes: a memory configured to store at least a first image; a one or more computer processors; one or more non-transitory computer readable storage media; and program instructions. The program instructions include: receive the first image; determine at least one characteristic associated with an object represented within the first image and an expected user input associated with the at least one characteristic; and generate a sequence definition, the sequence definition including an identifier of the first image and an identifier of the at least one characteristic, where the sequence definition is configured to cause the first image to be interactively visualized to a user via a user interface to determine if a user input matches an expected user input based on the identifier of the at least one characteristic.
