How domain experts without expertise in VR development can be direct actors in the creation of Virtual Reality Environments for Training (VRET)? In order to facilitate a more hands-on approach to scenario authoring for domain experts, this paper proposes an extension of the Scenario Authoring Model with Pedagogical Objectives (SAMPO) for Virtual Reality. It expands SAMPO with accessible activity prerequisites, pedagogical guidance triggers, and learning activity selectors. This paper adopts the domain experts’ authoring perspective to describe the authoring process.
