Content Format and Quality of Experience in Virtual Reality
In this paper, we investigate three forms of virtual reality content
production and consumption. Namely, 360 stereoscopic video, the combination of
a 3D environment with a video billboard for dynamic elements, and a full 3D
rendered scene. On one hand, video based techniques facilitate the acquisition
of content, but they can limit the experience of the user since the content is
captured from a fixed point of view. On the other hand, 3D content allows for
point of view translation, but real-time photorealistic rendering is not
trivial and comes at high production and processing costs. We also compare the
two extremes with an approach that combines dynamic video elements with a 3D
virtual environment. We discuss the advantages and disadvantages of these
systems, and present the result of a user study with 24 participants. In the
study, we evaluated the quality of experience, including presence, simulation
sickness and participants' assessment of content quality, of three versions of
a cinematic segment with two actors. We found that, in this context, mixing
video and 3D content produced the best experience.Comment: 25 page
