Abstract
No campo da soldagem, a preocupação com fatores ergonômicos e de usabilidade deve-se à crescente incorporação de tecnologias computacionais e à conseqüente transformação das atividades executadas pelos soldadores. Sendo assim, o objetivo deste trabalho foi avaliar a usabilidade de um sistema interativo destinado à soldagem robotizada aplicando-se métodos e técnicas de engenharia de usabilidade. Assim, foram realizados, em laboratório, testes de interação com o equipamento em uma bancada especialmente construída para simular atividades típicas envolvendo a configuração de parâmetros e processos de soldagem. A amostra da pesquisa foi constituída por treze participantes envolvidos em atividades de pesquisa em soldagem. Para a coleta de dados foram utilizados questionários específicos para avaliar a satisfação dos participantes com a usabilidade do sistema. Ainda, para avaliar o desempenho dos participantes durante a realização das tarefas foram registrados os tempos e as taxas de conclusão. Dessa forma, verificou-se que o sistema interativo atendeu ou superou as expectativas dos usuários quanto à utilidade, facilidade de uso, facilidade de aprendizado e qualidade da interface. Por fim, a avaliação de usabilidade forneceu um diagnóstico dos fatores que representaram obstáculos para os usuários, e informações que poderão ser usadas no aprimoramento das próximas versões do equipamento.
In the field of welding, the concern with ergonomic and usability factors due to the increasing incorporation of computer technologies and the consequent transformation of the activities performed by welders. Therefore, the objective of this study was to evaluate the usability of an interactive system for the robotic welding by applying methods and techniques of usability engineering. So were performed in the laboratory tests of interaction with the equipment in a specially constructed bench to simulate typical activities involving the configuration parameters and welding processes. The survey sample consisted of thirteen participants involved in welding research. To collect data specific questionnaires were used to assess participants' satisfaction with the usability of the system. Yet, to evaluate the performance of participants during the tasks were recorded times and completion rates. Thus, it was found that the interactive system met or exceeded the expectations of users regarding the usefulness, ease of use, ease of learning and quality of the interface. Finally, the usability evaluation has provided a diagnosis of the factors that represent obstacles for users, and information that may be used in improving future versions of the equipment.
