“Save as…”. The role of a computer interface in digital ontology

The article provides the analysis of the computer interface as a digital world phenomenon in correlation with its constitutive and representative function for image production. Several concepts of media theorists and researchers of visual culture of new (i. e. digital) media (M. Hansen, D. Bruno, D. Drucker) are examined in the context of considering intermediary functions of interface between the computer code message and the user. The analysis of the project of art group Share Lab about the interface and algorithms of Facebook for user behavior is being carried out. The representative role of interface in production of the ontological reality of media is considered, which is correlated both with the production of a media event and with such concept of a contemporary world as “post-truth”. The conclusion is offered that the constitutive role of computer interface is manifested both in social practices of digital media users and production of media events with attention to its representative function.
