Influence of attention and predictive visual cue on motion perception and sickness in immersive virtual environment.

Relieving motion sickness and enhancing self-motion perception are required for the public application of immersive visual display system. The effects of user attention and predictive visual cue have been experimentally evaluated in this study. A viewpoint moving visual stimulus was applied to eighteen healthy adults. The subjective evaluation presumably suggested that a predictive visual cue enhances self-motion perception and relieves motion sickness at a same time.
