Uma abordagem de engenharia de requisitos para o processo de especificação e análise de requisitos em aplicações de realidade aumentada

Abstract

Augmented reality (AR) is characterized by the inclusion of virtual objects - such as images, texts, animations - in the real world, through technological devices, allowing the user to explore attractive and highlighted scenarios. One of the most valuable advantages of this technology is the ability to allow the use of multimodal interfaces, involving touch, gestures, and others. However due to its variety of interfaces the development of AR applications becomes an expensive task at the moment of specification and analysis of requirements. This work presents an approach composed of a set of activities based on the concepts of Requirements Engineering (RE) and the particular characteristics of AR to assist in the process of specification and analysis of requirements for AR applications. Such an approach is intended to support the development of AR application requirements, avoiding errors that arise from the initial stage of production to propagate to other phases, and also to promote an effective integration in those involved, which in many cases are multidisciplinary teams. Moreover, such an approach meets an express demand in the literature. This work used a mixed methodological approach. In this case, the systematic review of the literature carried out with the purpose of mapping the evidences of the use of Requirements Engineering in the process of development of AR applications; and the experiments carried out to verify the main elements of AR applications; the application of an AR scenario in order to consolidate the developed approach; and also a case study in order to verify the adherence of the approach in the process of specification and analysis of requirements. With the execution of the methods it was possible to analyze the feasibility of this approach. The results indicated that the approach presented in this work is valid and can be applied in the productive sector, it is hoped, then, to assist the developers and to broaden the discussions and debates about their effectiveness.
