A lot of virtual reality (VR) experiences require switching between different environments or scenes. To achieve a plausible and perspicuous transition between those scenes, transition techniques can be used. These techniques visualize the change and should support continuity in storytelling and a high degree of presence while respecting the interactive nature of VR. We implemented six different transition techniques. Three of them are inspired by techniques which are used in movies since decades: Cut, Fade, and Dissolve. Furthermore, we added three techniques that leverage the peculiarities of VR: Portal, Orb, and Transformation. The techniques were compared in a user study regarding presence, continuity, usability, and preference. The results showed significant differences for all variables. In general, Orb and Portal received highest ratings.
