RESUMO

Virtual environments, also called virtual reality systems, are computational enviromnents that incorporate a style of Human-Computer interaction in which the signs to which hmnan beings are exposed, are generated by the computer in accordance with the point of view" of an individual participant. Early directed to scientific applications and to high-cost simulators, nowadays the virtual enviromnents are broadly applied to fields such as architectme, medicine, enterta.inment, education, psychotherapy, visualization, digital modeling of manufactures, communication and even in arts because of the confluence of 3 factors: the decrease in the cost of computational resources, the increase in the performance of processors and the development of efficient and robust algorithms for graphics and sound processing. Research on virtual environments has so far put a focus on the improvement of performance and quality of the response from the system. Concem with the design of the interaction of the human being in virtual enviromnents in a broad way is recent. Having as a background the Semiotics of Pierce, this thesis deals with the design of interaction of the human being in virtual enviromnents proposing the understanding of these enviromnents and of the design itself as a sign. We aimed primarily the development of a conceptual model for the interaction in virtual environments, the establishment of interaction design principIes and the creation of a design method for such environments. Secondarily, we analyzed the potential that the proposed conceptual model in being applied to other software classes and how the design principIes proposed may be used in a framework of logica1 inference related to questions that have to do with virtual environments. A virtual enviromnent prototype which allows children the development and the acting in theater plays was developed to illustrate the discussed concepts and to exemplify by practice the application of these concepts
