Abstract: Aspects of the disclosure provide remote training in a virtual reality (VR) environment. Multiple users may engage in the session. For example, a trainee may practice or be evaluated in performing a virtual version of a training task. A trainer may join the trainee's session. Embodiments enable the trainer to switch from a third-person perspective viewing the environment to the trainee's first-person perspective to see what the trainee is seeing. Virtual objects may be highlighted to guide the trainee's steps. Some embodiments may configure the training module to be engaged at various points out of order. For example, a user may select a specific point in a training sequence and work from there, replay or forward the environment in time to other points so that the trainee can skip or practice parts of the procedure.
