The XVR Platform provides a realistic and immersive learning environment for professionals involved in decision making in emergencies. XVR is used at the command level in emergencies and by strategic managers, both in individual and multi-agency scenarios. Similarly, XVR can be used to recreate past incidents and analyse the response provided and also to create evaluation scenarios that are predictable and repeatable to allow for the impartial evaluation of participants. The validity of the evaluations depends on the traceability of the results. A portable simulation platform for the on-going practical training and accreditation of Sea Rescue VTS operators.
