This article introduces a new concept, digital interactivity, through examining local digital culture; and video game culture is employed as a metaphor to interpret local digital culture. As a result, 'control-' and 'communication-based interaction are initiated, based on 'user to media' relationships. Based on the degree of physical interaction, 'liminal' and 'transitive' interactions are initiated. Less physical digital interaction is described as 'liminal' interaction and more physical digital interaction is described as 'transitive' interaction. These new classes of digital interaction can be applied to real-world examples, such as digital interactive installation artworks and video games.
