  Virtual Reality (VR) and Augmented Reality (AR) tools have been applied in
all engineering fields in order to avoid the use of physical prototypes, to
train in high-risk situations, and to interpret real or simulated results. In
order to complete a shared task or assign tasks to the agents in such immersive
environments, collaboration or Shared Cooperative Activities are a necessity.
Collaboration in immersive environments is an emerging field of research that
aims to study and enhance the ways in which people interact and work together
in Virtual and Augmented Reality settings. Collaboration in immersive
environments is a complex process that involves different factors such as
communication, coordination, and social presence. This paper provides an
overview of the current state of research on collaboration in immersive
environments. It discusses the different types of immersive environments,
including VR and AR, and the different forms of collaboration that can occur in
these environments. The paper also highlights the challenges and limitations of
collaboration in immersive environments, such as the lack of physical cues,
cost and usability and the need for further research in this area. Overall,
collaboration in immersive environments is a promising field with a wide range
of potential applications, from education to industry, and it can benefit both
individuals and groups by enhancing their ability to work together effectively.
