Camera Modes in Multi-user Virtual Reality Applications in Industry 4.0

virtual reality and a user using interaction through computer
peripherals. User cooperation is used in applications for Industry 4.0
in the field of employee training or in the deployment of digital twin
companies.
Four scenarios are devoted to the possibility of displaying scenes
and the use of avatars in virtual reality using outside in tracked
headsets and a user using a monitor display with control via a
keyboard and computer mouse. Within the scenarios, we define the
VR view, the use of a free camera, the character mode, and the
automatic orbit camera, the movement of which depends on the
position and orientation of the user in space in virtual reality.
We show the applications of individual scenarios in a case study of
user training in the field of mining and production in industrial
enterprises.
In the tests, we compared the increase in productivity of employees
after training with the use of assisted VR in a multiuser
environment.
