Interactivity and Interoperability in the Freehand Drawing: Digital Approaches Supporting Education

In the context of the digital revolution, the concept of ‘connection’ takes on a crucial value, enabling a transversal vision of knowledge, techniques and tools. The exchange of data in it environments is regulated by the ability to interact and function, measured by the degree of interoperability, which aims to ensure the best cooperation between systems or products. The article aims to investigate the relationship between analogue design and its digital reformulation - assisted, redefined, restructured, conformed, parameterized, even virtualized - exploring new possibilities of conceiving and constructing representation, either as a graphic schematization of a thought, in artistic or technical form, or as a tool to understand or prefigure. Specific hardware and software tools aim to establish a continuum between the freehand stroke and its analytical formulation within computer management. In this sense, terms such as interactivity and interoperability are provocatively introduced, which are not immediately associated with freehand drawing. Teaching is facing these approaches with ever-increasing expectations, evaluating the opportunities and methods for the inclusion of targeted training experiences. In this way, methods and techniques of representation useful for an enrichment of the outline of the future architect or engineer can be achieved already in the early academic years.
