An important problem in development of an integrated multi-functional system of video monitoring and recognition of objects is the problem of an interface that would provide a link between various programme applications of the system and between applications and users. This interface must be configured with reference to the object that the system of video monitoring will be attached to, and it must be based on data transmission channels, skills and competences of users. The authors specify the basic requirements to the software and the user interface. The concept is implemented as a self-software facility that has successfully passed a test in ergonomics and speed. In this project, an attempt is made to develop and implement a user interface that assures the best relationship between individual modules of an integrated system and between the system and the user. Therefore, the interface is to meet the following requirements: flexibility, volatility, mobility, and frequency of principal forms and templates. Design and development of a user interface incorporates development of pattern dialogues, resolution of user problems, WIMP (window, icon, menu, pointing device), applied graphic scenes, as well as connection of the interface to the application. The characteristics of users are employed as the criteria of the interface adaptability; they can be divided into the following semantic groups: demographic indicators, individual psychological features, psychomotor qualities, cognitive abilities, training and qualification, motivation, nature of the system interaction with software applications. This approach assures a high productivity of user actions through improvement of ergonomics and better performance of the interface.

A experiência e o aprendizado adquiridos em simuladores estão diretamente relacionados à qualidade e ao realismo dos cenários de treinamento propostos. Em contrapartida, o processo de construção de cenários de treinamento é uma atividade complexa, que envolve um grande volume e variedade de informações e, que demanda da equipe responsável conhecimentos multidisciplinares (design do ambiente virtual, educação, domínio especifico, etc.) . Nesta pesquisa propõe-se uma abordagem sistemática para a construção de cenários de treinamento de operadores de sistemas elétricos em ambientes de simulação. Esta abordagem se apoia dentre outras fontes: na instanciação de ontologias de domínio; nas normas IEC 61970-301 e ISO 10015; no contexto do treinamento em sistemas elétricos; na observação de treinamentos realizados na empresa CHESF e em documentos relacionados, gentilmente cedidos por esta empresa do setor elétrico. Com base nos termos, relacionamentos e restrições definidos, foram descritos os elementos constituintes de um cenário de treinamento, possibilitando o seu reuso em diferentes cenários, a partir de sua combinação e configuração, de acordo com informações armazenadas em uma base de conhecimento. Os objetivos deste trabalho foram: propor uma abordagem sistemática dos cenários visando facilitar a construção dos cenários a partir da formalização do conhecimento em ontologias do domínio; disponibilizar uma estrutura de dados reutilizável capaz de auxiliar tutores no processo de autoria do ambiente virtual; facilitar a compreensão dos requisitos de treinamento; favorecer a reusabilidade e a escalabilidade dos objetos representados nos cenários tais como: os componentes de animação e os modelos de simulação. As ontologias e o processo de desenvolvimento de cenários de treinamento foram validados a partir da descrição de cenários reais para o treinamento no simulador 2D utilizado na empresa CHESF- Simulop e na construção de cenários para o Simulador 3D- SimuLIHM, desenvolvido no LIHM da UFCG. The industrial training of system operators in simulated environments favours the assimilation of technical procedures by reproducing similar to real situations experienced in the workplace. The experience and learning acquired in simulators is directly related to the quality and realism of the proposed training scenarios. However, the process of building training scenarios is a complex one, involving a large volume and variety of information. It also demands from the development team a multidisciplinary knowledge of the virtual environment design, education, specific field, etc.). In this research it is proposed a systematic approach for building training scenarios in simulation nvironments, for electric system operators. This approach was based, amidst other sources, on: the instantiation of domain ontologies; IEC 61970-301 and the ISO 10015 standards; in the context of training in electrical systems; training observations conducted at the Brazilian electricity company- CHESF and related documents kindly made available by this company. The components of a training scenario were described on the basis of the terms; relationships and constraints defined, thus enabling their reuse in a variety of other scenarios, through their configuration and combination, in accordance with the information stored in a knowledge base. The objectives of this study were: to propose a scenario authoring process to facilitate the building of scenarios supported by the formalization of knowledge in domain ontologies; to provide a reusable data structure capable of assisting tutors in the virtual environment authoring process; to facilitate the understanding of training requirements; to promote reusability and scalability of the objects represented in scenarios such as: animation components and simulation models. Both the ontologies and the training scenarios development process were validated through the authoring of real scenarios for training in 2D simulator in CHESF- Simulop and, authoring scenarios for the 3D-SimuLIHM Simulator, developed in LIHM UFCG.
