Collaborative educational environments incorporating mixed reality technologies: a systematic mapping study

In this paper, we report findings from a systematic mapping study, conducted to review the existing literature on collaborative educational environments incorporating mixed reality technologies. There is increasing interest in mixed reality technologies in education, especially with the introduction of new Over Head Mounted Displays (OHMDs), such as HoloLens, Oculus Rift and HTC Vive. with the consideration of areas such as education, dynamic technology and complex environments, a research area is identified. We carried out an extensive review of the literature from 2007 to 2017 and conducted an analysis of the works on mixed reality technologies and its subcategories applied to collaborative education environments. Results highlighted the lack of research across the mixed reality spectrum, especially in the augmented virtuality subcategory, as well as technical limitations such as response time in the development of mixed reality technologies for collaborative environments. Furthermore, the difficulty of teaching professionals to replicate mixed reality experiments in real environments, due to the technical skills required, was identified. The main contribution of this article is the discussion of the current works with visualization of the present state of the area, which is aimed to encourage educators to develop mixed reality artefacts and conduct further research to support collaborative educational environments
