The Brazilian Symposium on Virtual and Augmented Reality (SVR) celebrated its 10th edition in 2008, in the city of João Pessoa. During these last 10 years, SVR has earned its space and magnitude as a truly consolidated event within the Brazilian research community. The papers in this special issue of RITA were selectively chosen among the 24 full papers presented in SVR 2008. They are extended and revised versions of those originally presented in the symposium. The material in this special issue is representative of the wide scope of the areas covered by the symposium. The first paper, the only one not presented at the symposium, was written by the editors jointly with Luciano Soares and Veronica Teichrieb. It provides a rich panorama of current Brazilian research in Virtual Reality (VR) and related areas, based on an analysis of the 124 full papers presented over the last four SVR editions. The second paper, by Silvano Malfatti, Selan dos Santos, Luciane Fraga, Claudia Justel, Paulo Rosa, and Jauvane Oliveira, describes some interesting VR work. Its authors present an engine (EnCIMA) aimed at the quick development of VR applications. The third paper, by Fábio Miranda, Romero Tori, Cláudio Bueno, and Lucas Trias, presents research results from the Augmented Reality (AR) area. This paper, which received the best paper award in the symposium, presents a projection-based AR X-Ray tool to allow visual exploration of internal details of walls, as an illustration. The fourth paper, by Leandro Fernandes, Vitor Pamplona, João Prauchner, Luciana Nedel, and Manuel Oliveira, explores 3D user interaction. It presents the implementation of a data glove that uses a camera to track visual markers at finger tips. Finally, the last paper, by Ednaldo Pizzolato, Diego Duarte, and Marcio Fernandes, explores speech recognition as a form of interaction, introducing a software framework for application developers.

Currently an increasing number of head mounted displays (HMD) for virtual and augmented reality (VR/AR) are equipped with integrated eye trackers. Use cases of these integrated eye trackers include rendering optimization and gaze-based user interaction. In addition, visual attention in VR and AR is interesting for applied research based on eye tracking in cognitive or educational sciences for example. While some research toolkits for VR already exist, only a few target AR scenarios. In this work, we present an open-source eye tracking toolkit for reliable gaze data acquisition in AR based on Unity 3D and the Microsoft HoloLens 2, as well as an R package for seamless data analysis. Furthermore, we evaluate the spatial accuracy and precision of the integrated eye tracker for fixation targets with different distances and angles to the user (n=21). On average, we found that gaze estimates are reported with an angular accuracy of 0.83 degrees and a precision of 0.27 degrees while the user is resting, which is on par with state-of-the-art mobile eye trackers.

Editorial Foreword

This special issue of the JIS (SBC Journal on 3D Interactive Systems) is in the second year acknowledging the best papers of the Symposium on Virtual and Augmented Reality. In the SVR 2011 several interesting research projects in the field of Virtual and Augmented Reality appeared and among the best papers this issue presents two selected papers for the readers of JIS. The SVR is the most important event on Virtual and Augmented Reality in Brazil, which is being conducted by academic professionals’ members of the Brazilian Computer Society (SBC) that is supporting the conference for many years. The two papers in this issue were selected among the best papers presented at the SVR 2011. Although the technical implementation of the papers is different each other, they try to solve problems of communication and location. It is possible to note that the virtual and augmented reality is really changing our life style, and these papers show important ideas that can be directly applied by people around the world. The paper “xGroupware: Supporting Collaborative Cross-Reality Environments using Multiagents System” authored by Katia Vega, Débora Cardador, Hugo Fuks and Carlos Lucena, presents very modern proposals of meetings, combining the virtual and real in a way that users can really take advantage of the resources available to improve their communication. It is also important to say that the clever idea to use multi agents in the system as an autonomous way to perceive and interact with the situations of the meetings is amazing. Finally the integration of wearable computing devices in the system makes it very interesting and probably reflects meetings of the future. The second paper “A Case Study of Augmented Reality for Mobile Platforms” authored by Gabriela Tinti Vasselai, Dalton Solano dos Reis and Paulo Cesar Rodacki Gomes presents how the mobile devices can contribute to help our localization with the resources of augmented reality. The paper shows that the resources available in the mobile devices can be used to augmented reality purposes although some improvements in the mobile platforms must be done. We would like to thank all the reviewers of the process, the editors and staff that supported us with the submission system, and of course the authors that had to extend and adapt their papers in order to have some new content that makes this special issue an important reference point for virtual and augmented reality research.

Risky Business

This special edition of Information Technology in Construction is focuses on new realities in construction. The editors have curated a series of papers intended to provoke speculation on the potential future of construction in the 21st Century and beyond. This edition grew from ConVR 2018: Evolving Construction, a conference held in Auckland, New Zealand. Where researchers reported on ideas, innovations and applications for virtual and augmented reality for construction. Authors of excellent papers were invited to extend their submission for publication in this special edition. Thus, this issue presents a glimpse into the state of research focused on construction and specifically the topic of ‘virtual and augmented reality’ in its broadest sense. The Architecture, Engineering and Construction (AEC) sector is age-old, comprises a variety of stakeholders and professions and is worth trillions of dollars globally. It is also a fiercely complex and risky business, which is highly regulated, because of this, change and innovation can occur slowly. However, we are now in the 21st century, a century that has come to be defined by fast changing technology. What are the implications for the AEC industry?

Virtual And Augmented Reality

The aim of this work is to study the development of virtual and augmented reality environment for the support of human-based processes in manufacturing. Virtual and augmented reality technologies can significantly reduce the development time and cost of products and processes in manufacturing. However there is currently a big gap between the conventional CAD-based processes and the advanced prototyping and validation methods offered with the use of VR and AR technology. There is a need for the virtual environments to be enriched with intelligence through the incorporation of knowledge. This will allow for complex tasks to be carried out, thus reducing the need for an ad hoc development, while the reusability of such an environment will be increased. On the one hand, augmented reality environments based on semantic knowledge and new user interaction methods can provide the means for putting the human back in the process loop at manufacturing level. On the other hand, virtual reality environments coupled with semantic knowledge can provide methods and tools that integrate 3D geometries with information/knowledge so that engineers can effectively evaluate and manipulate virtual prototypes in an immersive and interactive environment. Within the current dissertation, a generic VR and AR approach is developed based on human task analysis and knowledge mapping methods that are implemented in a Virtual and Augmented Reality Framework. The VR/AR framework is developed to be used with the two-step method approach using advanced interaction techniques. The developed method and framework are validated through a series of real life manufacturing test cases derived from both the automotive and aerospace industrial practices. Finally, an evaluation of the proposed methods and framework is carried out, based on one of the industrial test cases using quantitative metrics, giving insight on to the improvement of the engineering workflow using the proposed work compared with the conventional physical workflow.
