Nesta dissertação, apresentamos um panorama teórico das propostas de sistemas interativos no live electronics, bem como, os autores discutem e consideram a formulação de interação e interatividade dessa prática. Para isso, iniciaremos com uma breve retrospectiva do que consideramos como live electronics e do que consideramos interação até chegar no atual estado dessa vertente musical. Assim, apresentamos os pontos de discussão acerca de Robert Rowe, Garth Paine, Simon Emmerson, Philippe Manoury e Agostino DiSpio, na qual discutem sobre esta área de composição. Conseguinte, realizamos uma exposição sobre a perspectiva semiológica, nos fundamentando na teoria elaborada por C. S. Peirce, para que entendamos como o fenômeno musical por meio desse viés. Assim, expor a emergência de significação para que possamos compreender como o modelo tripartido de Jean Molino nos inspirou para relacionar suas respectivas dimensões dos processos poiéticos, estésicos e o nível neutro dentro da tríade peirciana de significação. Por fim, realizamos uma análise dos métodos composicionais da obra Traverser la réseau, baseados nas questões expostas sobre a tripartição aplicada para este fim numa obra do tipo live electronics. / In this research, we present a theoretical overview of the proposals of interactive systems in live electronics music, as well as, how the authors who discuss this matter consider interaction on this type of music. To do this, we start with a brief retrospective of what we consider live electronics and what we consider what interaction is until the actual state of discussion to get to the current state of this musical strand. Thus, we present some points of discussion about Robert Rowe, Garth Paine, Simon Emerson, Philippe Manoury and Agostino DiScipio which discuss this area of composition. Consequently, we conduct a exposition about the semiological vision, based on the theory elaborated by C. S. Peirce, for the understanding of the musical phenomenon through this view. Thus, from an emergence of signification for a tripartite model of Jean Molino, we will be inspired to identify the perspective of the poietic, estesic processes and the neutral level within the Peircian triad of signification. Thus, we can have a statistical analysis of the interactive processes of a live electronic work. Finally, we performed an analysis of the processes of the peace called Traverser la r´eseau, based on the questions on tripartition applied for this purpose in a work of type live electronics.

In current component models, interaction aspects of system behaviour are mostly specified by components, rather than by composition mechanisms, due to the fact that most composition mechanisms cannot express complex interactions. Consequently current component models do not enjoy the benefits that arise from separating the specification of computation from the specification of interaction in software architecture. This thesis investigates the possibility of representing recurring patterns of interaction as composition mechanisms (and other associated component model entities), as distinct from components that define computation; these composition mechanisms would appear as first-class entities in architectures, and can be stored in and reused from repositories. To this end, we have defined a novel, control-driven and data-driven component model that strictly separates computation from interaction. To represent interaction patterns in this model, we have defined composite connectors that can encapsulate control flow and data flow and can be reused via repositories in different contexts. We have also developed a prototype implementation of the component model, and carried out a case study from the reactive control systems domain in order to evaluate the feasibility of our approach. Comparison with related work shows that our composite connectors improve the state of the art in component-based interaction modelling (i) by specifying control flow and data flow explicitly and separately in software architecture; and (ii) by increasing the reuse potential of interaction patterns compared to patterns that are represented by components only.
