In this paper, we consider two different concepts that include both slides and VR technology in one presentation, mixed presentations, and virtual presentations, and examine the role of the presenter in these concepts. We conducted three user studies which indicate that it is not necessary that presentations need to be held completely in VR as both virtual and mixed presentations were accepted by our participants, and that our participants preferred immersed presenter integrations.enShort Virtual Reality ExperiencesSlideshow PresentationsGame Engine IntegrationE-Learning10.18420/inf2020_891617-5468
