In this paper, we evaluate the influence of different
VR rendering styles on the QoE of users of a training application.
To this end, we present the results of a lab-based QoE study
featuring a virtual manufacturing training setting in which
participants were asked to correctly allocate spare parts to
mounting locations inside and outside a vehicle using an HTC
Vive VR Setup. We evaluate how five different rendering styles
(defined by rendering technique and shader used), ranging from
point cloud to highly photo-realistic, affect different quality
dimensions such as perceived visual quality, task difficulty, spatial
orientation ability, and discomfort (including cyber-sickness). Our
results show that while rendering style has a significant impact
on QoE and other dimensions (like task completion time), a
standard shader already can provide sufficient quality to support
the provided training task and can even outperform rendering
styles using more sophisticated techniques like ambient occlusion.
Furthermore, we also discuss significant influence of user-related
factors like previous experience with VR as well as gender as well
as other related critical issues to be considered in VR training
application and assessment study design.
