This paper discusses the conflicting expectations for media artists taking part in art-science collaborations. Despite the increasing opportunity to participate in these interdisciplinary projects, it can be unclear how media arts activities are best articulated, or even if they need to be defined at all. Additionally, this paper examines a methodological framework widely used in the visualization community for identifying different visualization tasks within research activities. Inspired by its success, this paper proposes a new methodological framework for media arts activities in art-science contexts. This framework splits media arts activities into overlapping areas: generation, augmentation, provocation and mediation, providing a useful way to articulate the broader importance of media arts in interdisciplinary collaboration.
