In this paper, we introduce a novel web-based tool built upon our previously developed relational model, designed for modelling, visualising, and generating interactions in interactive art. The current version of the tool focuses on modelling and visualising interactions and comprises two main components: a set of formal input fields for describing an interaction and a visualisation component that automatically generates a visual graph based on the description. We demonstrate the tool’s modelling capabilities and adaptability through three example artworks, encompassing both conventional and unconventional interactive art. The tool’s formal structure enforces the precision of descriptions and facilitates the modelling process. By producing a consistent data structure, it enables systematic comparisons of diverse interactive artworks. Furthermore, this approach enables us to implement features for exploring new interactive dialogues. Compared to the relational model, the tool places greater emphasis on the relational exchange between interacting elements and aids in identifying and contextualising known interaction models within an interaction. In addition to discussing its qualities, we address current limitations and our plans for future research and development. By sharing the design and development process of the tool and our insights, we aim to showcase how this approach can facilitate both the research and creation of interactive art and inspire the development of modelling tools and applications.
