General framework of geometric simplification for mitigating cybersickness
Communication avec acte
Virtual reality have advanced rapidly and are spreading in much of the world for huge numbers of application domains. However the cybersickness appears for many VR users and it is still a significant issue preventing them to feel free to use VR technology. In most of VR experience, the immersive display system can provoking much more self-motion perceived by eyes than the one given by vestibular systems. Through the sensory conflict theory, the mismatch in visual and vestibular sense causes sickness. In this paper a general framework for applying geometric simplification on the virtual scene is proposed with the aim of lowering the visually induced self-motion that can be quantified by optic flow analyzed on the rendered images. The synthetized image that includes original scene at central part and simplified scene at peripheral part, are rendered to VR users. The analyzed optic flow on the synthetized images is much less than the one given by the original images.
