We report an empirical study on the use of current VR technologies for requirements gathering in the field of simulation and training. We used synchronous and asynchronous traditional techniques plus collaborative virtual environments such as MozillaHubs and AltspaceVR. Our results show that requirements gathering in VR makes a difference in the process of requirements identification. We report advantages and shortcomings that can be useful for future practitioners. For example, we found that VR sessions allowed for better identification of dimensions and sizes. VR sessions for requirements gathering could also benefit from better pointers and better sound.
