An interface is the point of contact through which a viewer or user reads, navigates, and acts within a work or system. In the provided context, it appears especially in web-based and game-related art as the visible structure and operational layer that makes interaction possible. CSS and HTML, for example, are not only tools for visual composition but also part of the interface that shapes how a browser-based artwork behaves and feels. In this sense, the interface is not merely decorative; it is a core medium that organizes the experience of the work.
The passages also describe a broader technical role for interfaces in interactive environments, game engines, and real-time simulation. As experiences become more intuitive, the underlying engine, server, and data formats become less visible. The interface therefore both presents the range of actions available to the audience and helps define that range in advance through technical infrastructure. In this way, the interface is part of what determines how a world can be operated, not just how it is seen.
In participatory works such as tabletop role-playing formats, the rules and conversational framework that allow participants to become co-developers can also be understood as an interface in a wider sense. However, based on the provided sources, this entry is limited to interface as a concept in web art, interactive systems, and game-like artistic works.
