Editors’ Note

Abstract

It is our pleasure to introduce you the second issue of JIS in 2017. This issue contains six papers of the Special Issue of the 15th Brazilian Symposium on Human Factors in Computing Systems (IHC 2016). As we have been doing since IHC 2014, the best papers of the conference are invited to submit extended versions to a special issue of JIS, guest edited by the conference program chairs. In the current publication, our guest editors are Profs. Carla Leitão, from Pontifícia Universidade Católica - Rio de Janeiro (PUC-Rio), and Luciana Salgado, from Universidade Federal Fluminense (UFF), who we thank a lot for the dedication in the preparation of this issue. We invited you to read their editorial in the following.

We also have in this issue an original paper by Paulo Paiva, Liliane Machado, Jauvane de Oliveira, and Ronei de Moraes, entitled “Networking Issues for 3D Medical Collaborative Virtual Environments: Design and Applications”. The authors discuss specific networking issues for Collaborative Virtual Environments (CVEs) applied to the simulation of medical procedures. They designed, developed, and validated a peer-to-peer multicast architecture on the collaborative module of the CyberMed Virtual Reality framework, aiming at providing better network scalability.

Finally, we would like to thank the authors and reviewers that contributed to JIS. At the end of the issue we acknowledge the reviewers that contributed to JIS in 2015, 2016, and 2017.

JIS Editorial Board is looking forward to receiving your contributions. We hope you enjoy reading this issue!
